Multipurpose, ecological water-paint

Technical Field

The present invention relates to a new and original water-paint, in liquid form: a milky emulsion (pasteurized whole milk or powdered milk diluted in water) containing low amount of water and comprising minerals, acetic acid solutions and other components. Said water-paint, more than other similar products on the market, having bactericidal, fireproof, transpiring, ecologic, isolating, desalting properties is suitable for manufactured building articles, wood, metals and plastics. Coatings is, in general, the field of application of the present invention. A normal varnish is usually a solution and/or a suspension of variable consistency, with or without coloring pigments, characterized by the fact that upon application on whichever object it forms, on drying, a tough, resistant film with protective properties. The varnish consists of a liquid vehicle in which coloring components, in case of a colored paint, and various additives are suspended. The liquid vehicle once composed of oils, is nowadays composed of synthetic resins obtained through polymerization or polycondensation. Solvents or thinners (alcohol, esters, etc.) are the binding elements. Peculiar

characteristics are given to the paint by substances called additives among which driers, suspending elements, plasticizers etc. are to be mentioned. In particular, the group of plasticizers, as an integral part of the film, improves elasticity and flexibility. Disclosure of the Invention

The present invention is characterized by its new original composition whose advantages are not easily found in common coatings. The fundamental principle of the present invention is that the milk (whole pasteurized milk or powdered milk) allows to amalgamate in a solution with a low amount of water the following elements: a) minerals as calcium sulfate also in form of powdered stucco; litophone or a mixture of barium sulfate and zinc sulphide; silicon oxide; calcium oxide; calcium carbonate; calcium hydroxide; cement; talc and all the alkaline or alkaline-earth minerals; b) aqueous solution of acetic acid obtained with wine, beer, cider and other slightly alcoholic liquids through distillation and synthesis processes with a percentage of 6 to 15% acetic acid; c) wood (wood shavings); d) polyacrylic, polyvinyl and polyeurethan products; e) polysaccharides having either a mechanical function (cellulose, chitin) or a thickening function (wheat flour, oatmeal, corn meal, bonemeal, fishmeal, beet sugar and cane sugar, fructose, saccharose and dextrose);

f) drying oils like hempseed oil, linseed oil and tung oil mainly composed by glycerides of unsatured fatted acid charged with lead oxides, zinc oxides and manganese oxides or cobalt, lead and manganese resinates obtained by fusion with colophony; g) essential oils as fruits, flowers, leaves and wood oils obtained by organic solvents; h) repellents as silicon oils, organic mixture obtained by polycondensation of alkyl-silanol trioxide (RSi (OH)3) and di-alkyl silanol dihydroxide (R2Si (0H)2); i) pigments as oxides, bioxides and soil;

1) bleaching agents with both oxidizing and reducing properties;

The emulsion of the said components is achieved by centrifugation starting with the following basic components: milk, vinegar, calcium hydroxide (slaked lime), lithopone and powdered stucco.

Aim of the described water-paint is the protection of whichever painted surface, horizontal or vertical, from mildew, hydroscopic salts, potassium nitrate efflorescence and other salts. It also acts as dehumidifier.

Another application of the said water-paint is the coating of walls in a good state so that they will be imperious to air and moisture.

A further application of the said invention is its employment as additive for mortars in a proportion of

20-30% for stucco and 50% for plaster.

The mentioned properties are achieved because the

water-paint application on walls, for instance, causes a strong exothermic reaction of the acetic acid and the lactic acid on the calcium hydroxide producing water vapor; contemporary, the calcium sulphate, needed to be hydrated, absorbs the water of a humid wall or of ossidrilic basis of the salts in the walls. The desalting action is carried out by the lytophone, which through oxide reduction substitutes the hydroscopic salts; on the other hand, the water removal prevents the melting of corrosive hydroscopic salts and the formation of efflorescence both where there is water- paint and nearby it. The heat developed after the exothermic reaction causes the drying of mildew thus restoring the walls below. Another important role in the dehumidification action is played by the calcium sulphate which, having been emulsionated, has not stabilized with two water molecules. After the application of the water-paint this process produces a compacting effect of the paint on the wall. Ways of carrying out the invention

The water-paint is obtained by the following partial mixtures previously thoroughly amalgamated: a) 13% powdered stucco with 6% pastereuzed whole milk and 2.5% vinegar in a solution with a low amount of water; b) 13% lytophone and 3% paεtourized whole milk and 2% vinegar in a solution with low amount of water; c) 2% white cement in powder and water; d) 2% titanium powder and water;

SUBSTITUTE SHEET

e) solution of 47% calcium hydroxide with low amount of water, and successively amalgamate 5% pastourized whole milk, water, and again 2% pastourized whole milk and 2.5% vinegar. Mix successively solutions a), b), c) d) and e) and add a 1% pastourized whole milk and 1% vinegar. Solution e) can be used separately as semitransparent primer coat to treat surfaces from mildews, saltpetre and/or moisture. The combination of solutions b) lithopone (doubled), c) cement, d) titanium and e) calcium hydroxide, produces a water-paint which can be used as primer coat and has optimal transpiration, covering and pigmentation properties to paint manufactured building articles. The quantities of the said water-paint components can be, then, summarised as follows: milk (10-17%), vinegar (6-8%), calcium hydroxide (46-72%) calcium sulphate (2- 16%) and litophone (9-15%).

Moreover, the following components can be added to the water-paint by dispersion through centrifugation: a) 0.15 in volume percentage essential oils to scent the paint; b) pigments: 0.5 to 1% in volume percentage oxides; 3 to 6% in weight percentage bioxides and/or soil; c) 5 to 15% in weight percentage white cement and/or talc and/or silicon to give a better mechanical resistance; d) 4 to 6% in weight percentage polisaccharides to better the mechanical resistance and 1 to 3% in

weight percentage addensing polisaccharides. To obtain stuccos, mortars and bonding agents suitable for filling, finishing, restoring and coating walls, wood, metals and plastic materials the following components should also be disperded through centrifugation in the basic emulsion: 1 to 3% in weight polyuretan products; 2 to 4% in weight polyacrilic products; 2 to 6% drying oils; 1 to 3% bleaching agents; 2 to 5% wood shavings. Example

A practical formulation of the water-paint according to the invention comprises a mixture of milk (10%), vinegar (6%) and linseed oil (1%) in which calcium hydroxide (72%), calcium sulphate (2%) and litophone (9%) are to be dispersed through centrifugation to obtain said water-paint.
