Title of Invention Fire retardant coating material

Technical Field

[0001] The present invention relates to fire retardant coating compositions, their reparation and use.

Background Art

[0002] Fire retardant coating is a type of paint or coating that is designed to provide a passive fire protection barrier to the underlying material. Fire retardant coatings work by creating a protective layer on the surface of the material that they are applied to, which helps to prevent the material from igniting or spreading flames in case of a fire. These types of coatings can be applied to a variety of materials, such as wood, metal, and concrete, and can help to reduce the risk of fire damage and increase the overall safety of the structure or object.

[0003] There are different types of fire retardant coatings available that offer varying levels of protection and are designed for use in different applications. For example, intumescent coatings are a type of fire retardant coating that expand when exposed to high temperatures, providing a thick, protective layer that insulates the underlying material and helps to prevent it from igniting or burning.

[0004] Overall, fire retardant coatings are an important safety measure that can help to provide increased protection against the dangers of fire.

[0005] One of the latest achievements in the field of fire retardant materials is the development of intumescent coatings. These coatings are designed to expand when exposed to high temperatures, forming a thick, protective layer that insulates the underlying material and helps to prevent it from igniting or burning.

[0006] Additionally, advancements have been made in the development of new fire- resistant materials, such as aerogels, which are lightweight, porous materials made up of nanoparticles that can withstand extreme temperatures and have excellent thermal insulation properties. These materials have the potential to be used in a variety of applications, including in the construction of buildings, in aerospace and automotive industries, and in personal protective equipment. [0007] Overall, ongoing research and development in the area of fire retardant materials continues to explore new and innovative approaches to improving fire safety and protection.

Technical Problem

[0008] Some FR treatments may produce unwanted secondary side effects, such as increased moisture content, reduced strength, and increased potential to corrode metal connectors. Some disadvantages of fire-retardant paints or coating include their short shelf life (no more than 8-12 months), this is due to the use of flame retardants, and a limited limit of resistance to fire and temperatures. High temperature resistant paint can tolerate temperatures up to 600 °C. One of the goals of this invention is to introduce a fire-resistant material that is resistant to high temperatures and direct flame.

[0009] Resistant to temperatures over 600 degrees,

[0010] Resistant to direct fire,

[0011] Durability and long life on the applied surface.

Description of Embodiments

[0012] This material is produced from the combination of different materials that are explained herein after. The weight percentage mentioned in the document has an exemplary aspect and is not restrictive.

[0013] 1 -SiO2 nanoparticles or silicon dioxide are known as silica in the industry. These porous nanoparticles have many capabilities and applications in various fields. These materials are composed of two elements, silicon and oxygen. Silica nanoparticles are mineral substances that have high potential due to their unique properties, have. These materials are very suitable for use in various industrial and medical areas.

[0014] Properties of silica nanoparticles are following:

[0015] High biocompatibility and low toxicity,

[0016] Ease of synthesis and low production costs,

[0017] Hydrophilic, [0018] High stability and stability,

[0019] The ability to be functionalized with a series of molecules.

[0020] 2-Mica consists of a phyllosilicate with the general formula (AB2- 3X,Si)4O10(O,F,OH)2 where: A usually stands for potassium, but can also be sodium, calcium, barium, or cesium. B can contain aluminum, lithium, iron, zinc, chromium, vanadium, titanium, manganese and/or magnesium. The composition of this mineral consists of a hydrous aluminum silicate with potassium or sodium, which has various forms. Mica is composed of oxygen, silicon, aluminum, potassium and some other impurities. One of the important features of mica is high electrical and thermal resistance.

[0021] 3-Calcium carbonate decomposes to form carbon dioxide and lime. Due to its acid-resistant properties, calcium carbonate is used in industrial settings to neutralize the acidic conditions of soil and water.

[0022] 4- Glass powder

[0023] The powdered glass is less than 60-mesh particle size and substantially all between 20 and 50 mesh.

[0024] 5-Kaolin or Kaolinite(AI2Si205(OH)4). Kaolin can be found is some sedimentary deposits where it is mixed with quartz and feldspar particles, it can be separated by wet processing methods. Kaolinite is a pure clay mineral crystal of one part alumina and two parts silica. Kaolinite is used as a filler in paper, rubber, paint, plastics, adhesives, & sealants.

[0025] 6- Methyl-hydroxyethyl cellose ethers (MHEC) or Tylos®

[0026] Tylos is cellulose concentrate or hydroxypropyl methyl cellulose. The substance is a white powdery solid with a light beige color, which is sometimes found in the form of granules. When dissolved in water, tylose forms a colloid, which is non-toxic and combustible, and can be mixed with agents.

[0027] Tylose has thermal gelling properties. That is, when the solution is heated to a critical temperature, tylose turns into a non-flowable and semi-flexible mass. Normally, this critical temperature is inversely related to HPMC solution concentration and methoxy group concentration. Specifically, the higher the concentration of methoxy group, the lower the critical temperature. Also, the higher the concentration, the less sticky or flexible the mass obtained.

[0028] 7- Surfactants or thinner

[0029] Surfactants are compounds that reduce the surface tension of liquids and can also lower their viscosity. In the industry, surfactants are commonly used as wetting agents, emulsifiers, and dispersants to improve the performance of coatings and reduce defects. Some common surfactants used in the industry include:

[0030] 1 . Nonionic surfactants: These are surfactants that do not have an electric charge and are commonly used as wetting agents and emulsifiers in water-based paints. Examples include ethoxylated alcohols and alkylphenols.

[0031 ] 2. Anionic surfactants: These are surfactants that have a negative electric charge and are commonly used as dispersants in water-based paints. Examples include sulfonates and carboxylates.

[0032] 3. Cationic surfactants: These are surfactants that have a positive electric charge and are used as emulsifiers and wetting agents in solvent-based paints. Examples include quaternary ammonium compounds.

[0033] 4. Amphoteric surfactants: These are surfactants that have both positive and negative charges and are used as wetting agents and emulsifiers in both waterbased and solvent-based paints. Examples include betaines and amphoterics.

[0034] Thinners, also known as solvents, are liquids that are added to paint to reduce its viscosity and make it easier to apply. Thinners are typically made from organic solvents such as mineral spirits, turpentine, or acetone. The type of thinner used depends on the type of paint being used and the application method. For example, oil-based paints require a different type of thinner than water-based paints. It is important to use the correct type of thinner to ensure proper application and avoid any negative effects on the paint or surface being painted.

[0035] 8-Pigment

[0036] Pigments and fillers are mass-produced from non-renewable raw materials.

Most of them are obtained by extracting (titanium dioxide and iron oxides) or from oil products. Pigments are synthetic organic or inorganic compounds that are insoluble in water, although some are soluble in organic solvents.

[0037] 9-Ammonia in aqueous form

[0038] Aqueous ammonia is a weak base due to the presence of ammonia, which can accept hydrogen ions from water molecules. Aqueous ammonia is highly soluble in water, allowing it to form a homogeneous solution. Aqueous ammonia is used as a cleaning agent in various industries due to its ability to dissolve grease, oils, and other contaminants. Aqueous ammonia is used to control pH levels in water treatment plants.

[0039] 10-Talc

[0040] A type of mineral is a type of hydrous magnesium silicate mineral, which is also known by other names such as soapstone, magnesium silicate monohydrate and talcum. Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2.

[0041 ] The structure of talc is such that it has weak intermolecular bonds. For this reason, some atoms may be included in its structure and lead to the formation of a new substance. For example, iron atoms can replace magnesium atoms and lead to the formation of minnostoite, or aluminum atoms can replace magnesium atoms and lead to the formation of pyrophyllite.

[0042] 1 1 -Sodium benzoate

[0043] A white crystalline chemical with the formula C6H5COONa. It can be produced by reacting sodium hydroxide with benzoic acid. Sodium benzoate is also widely used in the industry with the aim of preventing metal corrosion

[0044] 12-Acrylic resin

[0045] Acrylic resin is a common ingredient in latex paint. Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl. Acrylic resin is considered extremely weatherproof and is well-suited for outdoor applications. In solid form, acrylic resin can last for decades. [0046] Water, tylose along with ammonia is added and mixed together in a suitable container, this mixture gels immediately, and then surfactants or thinner, antifoam material are added to the said mixture, and then mica powder, glass powder, calcium carbonate, kaolin, talc, acrylic resin is slowly added to the mixture, which remains as a gel after 24 hours, and then in the second step, it can be mixed again with the necessary amount of silica and water, and then it is ready to use.
