Description
Technical field
The present invention relates to a kind of acrylic coating, is a kind of water-repellent preservation finish paint that adopts ACRYLIC EMULSION specifically.
Background technology
In present automobile industry, spraying paint in the outside of automobile is a very important operation, return the vehicle that repair in shop is managed after particularly hanging accident for some, its indispensable especially operation of spraying paint, existing automotive alcquer coating mostly is solvent based coating, common kind has Resins, epoxy, chlorinated rubber, vinylformic acid, urethane etc., wherein all contain a large amount of organic solvents, these solvents are to the healthy harmful and contaminate environment of workmen, and cost is higher.Just begun to substitute the novel antiseptic and rustproof lacquer development of organic solvent type coating abroad from the beginning of the seventies, but, do not obtained big progress over a long time because of technical difficulty is bigger.
Since the mid-80, the countries in the world legislations of environmental protection is to the restriction increasingly stringent of volatile organic solvent in the coating (VOC) content, and its replacer's research and development are also more urgent, and wherein the research key of water-based anticorrosive paint is the research of water-base resin.Through the research of decades, the water-base resin system of successfully having developed at present has water soluble acrylic acid, water-base epoxy, waterborne polyurethane resin, aqueous inorganic silicate and their modified resin.The outer finish paint that automobile is used has required good weather, and acrylic resin, urethane resin can be used widely with its better weather.Because the moderate cost of acrylic resin is so generally use acrylic resin to prepare finish paint at present.Water-based acrylic acid top-coat can satisfy the weathering resistance requirement, but present water-based acrylic acid top-coat gloss is lower than the oiliness acrylic acid top-coat, and gloss generally has only 10-20%, does not reach the effect of oiliness finish paint.Simultaneously its corrosion-resistant and wear resisting property also has bigger gap than the oiliness finish paint, therefore is badly in need of a kind of new acrylic acid aqueous antisepsis finishing paint of development to satisfy the requirement in market
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of acrylic acid top-coat is provided, be a kind of water-repellent preservation finish paint that adopts ACRYLIC EMULSION specifically, it mainly comprises softening water, aqueous acrylic emulsion and nano dye and filler, and other indispensable component, adopt the water-borne coatings of this component, can reach the painting effect of oiliness acrylic acid top-coat; Water-fast corrosion resistance and good; In addition, this water-based acrylic acid top-coat adopts water as the solvent environmentally safe, and is healthy harmless to the workmen, safe and convenient to use; Can adopt common spraying method, also applicable to airless spraying, the operating efficiency height, sagging does not ftracture, and just can finish the finish paint construction together; Except being applicable to that car body is decorated and protected, also can replace the oiliness acrylic acid top-coat to be used for the antirust of facility ferrous materials such as other vehicles, bridge, pipeline widely.
Technical scheme of the present invention is as follows: the prescription of this water-repellent preservation finish paint is as follows: by weight:
50～60 parts of aqueous acrylic emulsions,
Nano dye 15-30 part,
Filler 5-10 part,
Softening water 15-20 part
Film coalescence aid 5-9 part,
Owing to adopted the main component of aqueous acrylic emulsion in the present invention's prescription as finish paint, mainly can greatly reduce that finish paint uses and the environmental pollution that causes as solvent with water, and its painting effect can reach the effect of oiliness acrylic acid top-coat, and gloss can reach 50%: its water-tolerant; In addition, this water-based acrylic acid top-coat is owing to not adopting organic solvent, and is healthy harmless to the workmen, safe and convenient to use; Can adopt common spraying method, also applicable to airless spraying, the operating efficiency height, once Pen Tu thickness gets final product processing requirement, and sagging does not ftracture, and just can finish the finish paint construction together; And rate of drying is very fast, can finish spraying operation fast, extremely is suitable for the spraying and the patch work of automobile.
Why adopt nano-level pigment and abandoned original common pigments, mainly be exactly to rely on its small particle diameter directly to be attached to paint vehicle and get in the metallic surface, the sticking power and the uniform coloring that can improve pigment so greatly bigger aberration can not occur, convenient and easy reducing the cost during toning, simultaneously because the nano-level pigment excellent abrasion resistance, comprehensive raising the weathering resistance of whole sheet metal, adopt these pigment to play and remedy microgroove that self-defect caused on the sheet metal etc., in addition because its specific surface area is big, can play good impermeabilisation effect, so just can play and reduce anti-sealing of corrosive effect and air admission lacquer painting internal corrosion car body metal, improved the work-ing life of finish paint, nano-level pigment of the present invention, be lower than the pigment of 200 nanometers for fineness, as titanium dioxide, red iron oxide, carbon black, the mixture of one or more in the phthalocyanine blue etc., local accumulative phenomenon can not occur because its fineness is extremely low, so can improve its consumption to improve the result of use of finish paint; Simultaneously the filler that is adopted among the present invention is generally materials such as kaolin after ceramics powder, talcum powder, the calcining, barium sulfate, owing to adopted a large amount of nano-level pigments, replaced the effect of filler to a certain extent, therefore its consumption is controlled at 5-10 part, thus the difficulty that reduces cost and spray.In order to guarantee the stable of paint vehicle, the present invention preferably adopts softening water, and is to reduce the destruction that contained material brings for finish paint character in the ortho-water, optional with deionized water or distilled water.
Except the main raw material of above-mentioned employing, also contain following auxiliary agent in the coating formula of the present invention:
Flow agent, defoamer, adhesion promoter, dispersion agent etc., its total consumption weight part is 1-3 part, and film coalescence aid, its consumption is 5-9 part.
In addition, can also increase other auxiliary agents according to the difference of working conditions, above-mentioned auxiliary agent all adopts the auxiliary agent that can directly buy on the market to get final product.When the mixed system that adopts above-mentioned substance during as the raw material of coating, make the effect of auxiliary agent obtain maximum lifting, also make the performance of finish paint be greatly improved.
Wherein dispersion agent can be selected 5040 dispersion agents of Henkel KGaA company or the T-731 dispersion agent of U.S. Rhom and Hass for use; Defoamer is a BYK-141 type defoamer, and promotor is ADP type adhesion promoter, and the film coalescence aid that is adopted preferred alcohol ester-12, flow agent are BYK-306 type flow agent.
In sum, the invention provides a kind of water-repellent preservation finish paint that adopts ACRYLIC EMULSION, it mainly comprises softening water, aqueous acrylic emulsion and nano dye and filler, and other indispensable component, adopt the water-borne coatings of this component, can reach the painting effect of oiliness acrylic acid top-coat: water-fast corrosion resistance and good; In addition, this water-based acrylic acid top-coat adopts water as the solvent environmentally safe, and is healthy harmless to the workmen, safe and convenient to use; Can adopt common spraying method, also applicable to airless spraying, the operating efficiency height, sagging does not ftracture, and just can finish the finish paint construction together; Except being applicable to that car body is decorated and protected, also can replace the oiliness acrylic acid top-coat to be used for the antirust of facility ferrous materials such as other vehicles, bridge, pipeline widely.
