Abstract
The invention relates to water-soluble vacuum deposition coating. The formula of the invention comprises the raw materials (weight percent): vegetable oil and fatty acid thereof 10-20, polylol 2-10, phenolic resin 4-10, estolide 5-15, acrylic acid 4-8, modified chlorinated polyolefine 0-2, isocyanate 2-5, latent solvent 4-8, appropriate neutralizing agent and water 50-60, which undergo alcoholysis, polycondensation, addition, urethanation, latent solvent addition, pH value regulation and dissolution by adding water to produce the coating. The invention can be used for surface coating of vacuum deposition of products such as plastic, metal, ceramic, glass, unsaturated resin, wax, and paper and so on. The coating has the remarkable characteristic that the coating takes water as the solvent, which, during the preparation or the construction, saves a large amount of petroleum resource-petroleum solvent, also has no toxicity and odor, is not easy to burn and cause the hazard of fire accidents and human poisoning, and belongs to the environmental protection product.
Description
Technical field:
The present invention relates to the end, surface layer water soluble paint that a kind of vacuum coating technology adopts, be commonly called as water-soluble vacuum coating oil, can be used for the surface-coated of goods vacuum platings such as plastics, metal, pottery, glass, unsaturated polyester, wax, paper.
Technical background:
Existing vacuum metallizing coating, most of alcohol acid and polyurethane, phenolic aldehyde urethane or modification ammonia ester oil of adopting is to form with solution polymerization, and 50% petroleum solvent is wherein arranged approximately.In construction application, solids content only has about 12.5%, and all the other 87.5% are petroleum solvent, have not only consumed a large amount of energy, and initiation fire easily, has polluted atmosphere simultaneously.According to the data verification, because coating process condition harshness, general water soluble paint is difficult to adapt to.At present, still find no the water-soluble relevant report that crosses coating in pass both at home and abroad, more product-free supply.
Summary of the invention:
The present invention is directed to the weak point of above-mentioned vacuum metallizing coating, proposed a kind of water-soluble vacuum coating paint of excellent combination property, to adapt to the needs of harsh vacuum coating technology whole process.
The present invention mainly is made up of vinylformic acid, acid anhydrides, resol, polyvalent alcohol, isocyanic ester, vegetables oil and lipid acid thereof, solubility promoter, neutralizing agent and water, and its weight ratio ingredient comprises:
Vegetables oil and lipid acid 10-20 thereof;
Polyvalent alcohol 2-10;
Resol 4-10;
Acid anhydrides 5-15;
Vinylformic acid 4-8;
Modified chlorinated polyolefin 0-2;
Isocyanic ester 2-5;
Solubility promoter 4-8;
Neutralizing agent is an amount of;
Water 50-60.
Vegetables oil of the present invention can adopt Viscotrol C, Oleum Cocois, synourin oil, Chinese catalpa oil, Thistle oil, soya-bean oil, oleum lini or its mixed vegetable oil.Lipid acid can adopt linseed oil fatty acid, appropriate youngster's fatty acid oil, soy(a)-bean oil fatty acid or its mixed fatty acid; Polyvalent alcohol can adopt contract one or more mixing in glycerine, TriMethylolPropane(TMP), glycerol, hot the eleventh of the twelve Earthly Branches glycol, ethylene glycol, season the eleventh of the twelve Earthly Branches tetrol of multicondensed ethylene glycol, two; Resol can adopt the mixed phenol urea formaldehyde of modified phenolic resins, diphenylol propane formaldehyde resin, p tert butylphenol formaldehyde resin or described resin; Isocyanic ester can adopt one or more mixing in '-diphenylmethane diisocyanate, xylylene diisocyanate, tolylene diisocyanate, poly methylene poly phenyl poly isocyanate, the hexamethylene diisocyanate; Acid anhydrides can adopt one or more mixing in trimellitic acid 1,2-anhydride, pyromellitic dianhydride, phthalate anhydride, MALEIC ANHYDRIDE, the phthalic anhydride; Solubility promoter is one or more mixing in propylene glycol butyl ether, butanols, isopropylcarbinol, propylene-glycol ethyl ether, Virahol, diethylene glycol ether, the Diethylene Glycol butyl ether; Neutralizing agent is ammonia or organic amine, is used for adjusting the pH value of urushoil, adopts an amount of neutralizing agent, and the pH value that makes urushoil is 7.0-8.5, and to prolong its quality guaranteed period, organic amine can adopt triethylamine, diethylamine, dimethyl isobutyl hydramine or N, N dimethylethanolamine; The water of preparation water-soluble vacuum coating paint generally adopts distilled water.
The present invention, adopt vegetables oil to carry out alcoholysis, esterification, also can adopt fatty acid process, with resol addition, polymerization, with acrylic acid modified, carry out the ammonia esterification with isocyanic ester again, add solubility promoter, make acrylic acid modified phenolic aldehyde polyurethane dispersions, add neutralizing agent at last and adjust its required pH value, be dissolved in water, make water-soluble vacuum coating paint.
The present invention, its characteristics are:
1, owing to adopt a large amount of crude vegetals and lipid acid and natural resin in the prescription, so this coating has no side effect, and can do or oven drying at low temperature by gas, and paint film is plentiful, the luminance brightness height, and snappiness is good, and the starting material source is wide, moderate cost.
2, in order to adapt to harsh vacuum plating condition, improve the mechanical property and the chemical property of coating, therefore in prescription, introduced resol, vinylformic acid and isocyanic ester, improved the performances such as moisture-proof heat, water tolerance, luminance brightness and sticking power of filming greatly.Even coating only is 3 μ m, still can satisfy the coating technique requirement, stopped phenomenons such as Yi Qicai, cloudy colour, pull-away.
3, the free isocyanate content of coating is zero, and catalyzer adopts the heavy metal free salt, and product has no side effect, and meets the RoHS of European Union standard-required.
The present invention, its advantage is:
1, this coating is special in vacuum coating technology designs, and salient features is fit to the whole process of vacuum coating technology fully, both can be used as priming paint, can be used as surface protection coating again.
When 2, the present invention is applied to vacuum plating and applies, can convert 2-3 tap water mixing construction doubly, service tool can clean with tap water, has not only saved the bulk petroleum resource, and nontoxic, tasteless, nonflammable, is difficult for initiation fire and the personnel harm of poisoning.
3, this coating wide accommodation do not need to be specially adapted to surface-treated polyolefine material and to reclaim goods such as plastics, assorted material, glass.
