Description:
NON-REWETTING O/W (OIL IN WATER) EMULSIFICATION SYSTEM FOR HYDROPHOBIC

COMPOUNDS

Technical field

The present invention generally relates to a new emulsifying system comprising a combination of an organic amide, an organic amine and an acid, and an improved method for obtaining enhanced hydrophobicity of inorganic, organic or fiber based materials by different application methods and broad activation temperatures with a good washing and/or weathering-durability.

Background of the invention One of the main challenges in the emulsification of hydrophobic chemicals is to find a dispersive /emulsifying/surface active agent which does not cause rewetting of the treated material after application of the emulsion on the surface of the different materials (inorganic, organic or fiber based materials). While traditional surfactants can be used for emulsifying a hydrophobic agent in a water borne formulation, their interference with the final expected material surface properties due to their intervention in the final surface properties of the treated material in terms of back wetting, reduce the actual performance of the hydrophobizing agent used in the emulsion. Different non wetting emulsifying systems have been introduced to the market, for example, using thermolabile surfactants with controlled lifetime (Commercially available amine oxide surfactants) such as Cetapol 0X20 (Avocet Dyes Ltd) or volatile surfactants such as Surfynol 61 (Air Products)). However, the use of these systems is limited due to their inability to provide strong surface active properties at low usage levels, their requirement for long periods of heating (thermolabile surfactants) and usage safety among other problems.

The Swedish patent application 1651195-8 discloses an emulsion for hydrophobizing fibrous materials with hydrophobic agents employing selected aminosiloxanes that will act as a provisional emulsifier while in protonated form in the presence of an acid, but will subsequently lose their surface activity when introduced into a network with the fibers, so the problem of back wetting is eliminated. Despite this there is a need for a new emulsifying system for hydrophobization of materials without back wetting or rewetting that admits curing at low temperatures and admits low usage level of emulsifiers and allows a broad range of hydrophobic agents to be emulsified such as oils, waxes, and silanes and similar. At the same time, the organic base of the new emulsifying system according to the present invention, compared to aminosiloxane based emulsifying system, would pave a way to use bio-based materials from renewable resources and hence lead to a more sustainable product portfolio.

Emulsifying compositions have previously been suggested as means to enhance hydrophobicity of fibre materials, see for instance US 3374100 A.

Objects of the invention

It is an object of the invention to provide new emulsifying compositions comprising a combination of an organic amide, an organic amine and an acid capable of emulsifying a broad range of hydrophobic compounds. It is also an object of the invention to provide improved application methods to obtain enhanced hydrophobicity, a water repellency durable to weathering and washing and a repellency against water soluble dirt on inorganic, organic or fiber based materials allowing the usage of a broad range of activation temperatures.

It is also an object of the invention to provide cost-effective applications that result in immediate hydrophobicity or the treated materials with an emulsion that is dilutable in water, and is stable both in concentrated and highly diluted form (1:30), thereby enabling efficient add-on control on the treated material.

It is also an object of the invention to avoid back-wetting or re-wetting of the applied material, which may result from conventional surfactants (emulsifiers) on the material surface with the consequence that an extra cleaning step is required for the material to induce correct hydrophobicity. It is another object of the invention to provide means to use a non-rewetting emulsifying composition with an organic structure which can be potentially produced from renewable sources.

A further object of the invention is to provide means to use known industrially used methods and the chemical emulsion composition, for example in the current production methods of inorganic, organic or fiber based materials, such as textile, non-woven, wood, paper, glass, glass fiber, stone, brick, and the like.

Further objects of the invention are to provide a chemical emulsion composition for application with low viscosity, such as below lOOmPas, broad temperature interval for drying and curing, which causes no or very low yellowing of the treated material, immediately enhances hydrophobicity and water based dirt repellency, as well as a soft hand on relevant materials such as textiles, whilst avoiding the use of fluorocarbons.

A further object of the invention is to provide a chemical emulsion composition for application, which allows for simple manipulations, through the addition or partly substitution of one or more of the compounds of the chemical composition of the invention using said optional co-emulsifier, catalyst, preservative, rheology modifier or mixtures thereof to adjust the properties and effects of the composition on the treated material, and to further adjust the drying and curing times and temperatures.

Still further objects of the invention are to provide chemical emulsion compositions which induce highly durable hydrophobicity for different material, having immediate effects following the application, having good shelf life and with minimal adverse environmental effect when washed/leached out.

A further object of the invention is to avoid or strongly minimize the use of surface active agents/emulsifiers/surfactants which negatively affect the final hydrophobic properties of the treated material and which might have adverse effect on the environment when washed/leached out. These and other objects, features and advantages of the herein described invention will become more apparent from the following detailed description thereof. General description of the invention

It has surprisingly been found that by using an emulsifying composition comprising water insoluble amides and amines according to the present invention, improved interaction between the emulsifying composition and a hydrophobic agent is achieved. This improved interaction results in the emulsifying composition exhibiting improved dispersion, i.e. stability, of the oil-in-water system. As a result, the emulsifying composition is able to better distribute a hydrophobic agent on a fibre-based material. Without being bound to theory, it is believed that a non-water-soluble emulsifying composition is able to better support the hydrophobicity phase to assemble to a treated fibre based material, thus resulting in a more persistent water-repellency and reduced rewetting.

Detailed and exemplifying part of the invention

Evaluation Methods For determination of resistance to surface wetting (spray test) of fabrics, European Standard EN 24920 (ISO 4920:1981) was used. The principles of this standard are the following: A specified amount of water is sprayed on a textile specimen mounted on a ring. The specimen is disposed at an angle of 45° in respect to the nozzle. The center of the standardized nozzle is disposed at a given distance above the center of the specimen. A given amount of water is filled in a reservoir disposed above the nozzle and in communication with it. The spray rating is determined visually and/or photographically. The stepwise spray rating scale of ISO 1-5 corresponds to 50-100% of the specimen having withstood wetting. The scale correlation is 100 % (ISO 5), 97-5 % (ISO -5), 92.5 % (ISO +4), 90 % (ISO 4), 87.5 % (ISO -4), 82.5 % (ISO +3), 80 % (ISO 3), 77-5 % (ISO -3), 72.5 % (ISO +2), 70 % (ISO 2), 66.67 % (ISO -2), 56.67 % (ISO +1), 50 % (ISO 1) of the specimen having withstood wetting.

Dynamic contact angle measurements were performed using PGX Serial 50585 contact angle measuring device on the surfaces of the treated and non-treated paper boards for 120 seconds.

Curing of fabrics were made in a preheated Wichelhaus WI-LD3642 Minidryer/Stenter frame oven or Termaks TS 8136 oven at the given temperatures and times, or room temperature (5-30°C) hang drying, or tumble drying at the given time and temperatures or ironing at the given heat. The water-repellency properties of the treated textile before and after machine washing, using an aqueous solution of a IEC reference detergent B, were evaluated (washing temperature 40 "C/duration approximately 90 minutes) by testing the textile with the standardized tests SS- EN 24920.

Stability of the compositions was determined by following changes in viscosity using a Brookfield DV-11 Pro viscometer and visually by evaluation of phenomenas such as creaming or phase separation. 250 g of each emulsion were kept in 250 ml flasks with sealed cap at three different temperatures; room temperature (23 °C), 40 °C (Incucell, L LSIS-B2V/IC 55) and 50 "C (Avantgarde ED 115).

General procedures for the preparation of the emulsion of the invention

The invented emulsifying system can be utilized in different emulsification processes using different amounts of the emulsifiers, hydrophobic chemicals, Lewis acid/catalysis and water. The process temperature in the premixing stage of the components or the homogenization of the dispersing phase in water as continuous phase should preferably be, but not limited to, higher than the melting point of the solid components in the mixture. In order to prepare the emulsion with finest particle size, for better stability and functionality a good homogenization is a requirement. A higher shear force from the homogenizer device will provide smaller emulsion droplet sizes which normally leads to more stable emulsions. By balancing the dispersed phase and the continuous phase the use of conventional stirrers can be enabled, in the preparation of the final emulsion. However, the use of high shear homogenizer is preferred. Non limiting examples of high shear homogenization can be accomplished using high shear propeller, homogenizer, in line-homogenizer, sonication and high pressure homogenizer.

The following preparation method examples should not be interpreted as limiting the scope of the invention set forth in the claims. All percentages in these examples are weight percentages (wt%), unless otherwise indicated: Preparation method 1:

In a beaker organic amide, organic diamine, hydrophobic agent, coalescing agents and warmed deionized water were charged (the temperature of the water preferably can be adjusted generally just higher than melting point (mp) of the component with highest mp). The mixture was pre-homogenized primarily for short time. Then a solution of Acid/Catalyst was added to the mixture and homogenizing continued until optimal particle size was achieved.

Preparation method 2:

In a beaker a hydrophobic agent, organic amide, organic amine, optionally coalescing agents and co-surfactant were charged. The mixture was stirred using magnetic stirrer at moderate speed using warm water bath until the dispersed phase was prepared called phase I (the temperature of the water preferably can be adjusted generally just higher than melting point (mp) of the component with highest mp). The Acid/Catalyst was added to warm deionized water called phase II. Phase II was homogenized for short time. Phase I was added gradually to phase II while homogenizing. The homogenization was thereafter continued until optimal particle size was achieved.

Preparation method 3:

In a beaker hydrophobic agent, organic amide, optional coalescing agents and cosurfactant were charged. The mixture was stirred using magnetic stirrer at moderate speed using warm water bath until homogenized phase was prepared called phase I (temperature of the water preferably can be adjusted generally just higher than melting point (mp) of the component with highest mp). The Acid/Catalyst and water soluble organic amine were added to warm deionized water called phase II. Phase II was mixed until consistent aqueous phase was prepared. Phase II was then homogenized for short time. Phase I was added gradually to phase II while homogenizing. The homogenization was thereafter continued until optimal particle size was achieved.

After curing the treated textiles they were subjected to evaluation using EN 24920. It can be concluded that composition 1 outperforms comparative composition 2 when it comes to spray score. Also a comparison was made on the emulsion stability of the compositions. It can be clearly seen that composition 1 is stable over longer period of time than comparative composition 2.

Example 7. Performance on different materials

Composition 1 of the invention was tested on several different materials in order to evaluate the performance on different materials and surfaces by measuring the contact angle of water on the treated surface.

Table 10. Comparison of treated and non-treated materials and surfaces.

In all cases, according to table 10, the contact angle is increased after treatment with composition 1, which means that better hydrophobic properties are achieved. These results also demonstrate the broad application area of the composition for different materials and surfaces.

Example 8. Physical change on materials

Composition 4 of the invention was tested on White 100 wt% Polyester in order to evaluate hands-feeling and color change on different materials and surfaces. Table 11. Evaluation of the stiffness/softness and yel lowing/color change of treated textiles

The treated polyester textiles according to table 11 were submitted for sensory panel evaluation. The sensory panel utilized individuals trained to compare textile products and evaluate softness/stiffness and yellowing/color changes (against original untreated textile). Stiffness was ranked on a scale from 0 describing a very soft hand feel, to 7 describing a stiff hand feel. Color changes/yellowing was ranked on a scale from o, describing no change, to 7 describing as big visual change. According to the results shown in table 12 it can clearly be seen that the emulsions according to the invention could offer very soft feeling along with very low yellowing on the treated textiles.
