Abstract
The invention discloses a modified acrylic resin-based normal temperature quick-drying automobile paint with high fullness and high solid. The modified acrylic resin is formed by esterification and copolymerization of 5 to 10 percent of unsaturated fatty acid, 2 to 6 percent of polyalcohol, 3 to 7 percent of diacid or diacid anhydride, 10 to 50 percent of styrene, 40 to 80 percent of acrylic ester monomer and 0.8 to 3 percent of initiator in percentage by mass. The normal temperature quick-drying automobile paint has the characteristics of thermoplastic acrylic resin paint such as quick drying and good weather resistance, has good fullness and easy construction, is suitable for coating automobiles with high decorative performance, and also can be used for coating household appliances, machinery and the like. Because of high solid and low VOC emission, the automobile paint meets nowadays environment-friendly requirements.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of acrylic resin modified, acrylic resin modified preparation method and based on this acrylic resin modified high fullness ratio, high solid normal temperature quick-drying automobile finish.
Background technology
Acrylic resin paint is protected light, tint retention can be good, can keep the gloss and the color and luster of original paint film for a long time, fast light, good weatherability; The outdoor exposure weather resistance is strong, and the ultraviolet resistance irradiation is difficult for decomposing or flavescence; The acrylic resin varnish color and luster is very shallow, and fabulous transparency is arranged; Corrosion-resistant, the contamination and the corrosive nature of chemical such as acid-and base-resisting preferably, salt, grease, washing composition are arranged.Advantages such as domestic technique reaches its maturity simultaneously, raw material (Acrylic Acid Monomer) is in liberal supply are more and more accepted by the user, so its quantity increase is more and more, and kind is more and more complete, and the application and construction technology is also ripe gradually.Became development one of coating variety the most rapidly in recent years.
But acrylic resin paint also exist the paint film fullness ratio not good, to temperature sensitive, snappiness is poor, solid is low, to shortcoming such as the pigment wetting dispersiveness is not good, all weakness cause its suitability not strong.
Use alkyd modified vinylformic acid, both kept acrylic resin paint and protected light, protect characteristics such as look, corrosion resistance and good, make the acrylic resin modified characteristics such as the Synolac fullness ratio is good, easy construction that have again, and cost is lower, and outstanding cost performance is arranged.
The method of alkyd modified vinyl resin has cold spelling, acrylic polymer esterification process, copolymerization method.Cold spelling is exactly to mix at normal temperatures with Synolac for preparing and vinyl resin to get final product; Because molecular weight, polarity all differ greatly between Synolac and the vinyl resin; So consistency is bad; This method causes that gloss of film is poor, fullness ratio is bad, so basically need not.The acrylic polymer esterification process is owing to be first acrylic acid synthesizing prepolymer; Utilize carboxyl and the polyvalent alcohol esterification on the acrylic polymer molecule and make acrylic resin modified; But this method still is shortcomings such as Synolac, acrylic polymer esterification are incomplete owing to molecular backbone chain, shortcomings such as the paint film erosion resistance of preparation is bad, gloss difference.Thereby acrylic resin modified copolymerization method preparation commonly used.
Chinese patent 200510123053.3A is disclosed to carry out modification with Vinyl toluene to Synolac separately, but because a large amount of easy xanthochromias of Vinyl toluene, weathering resistance is bad, therefore can't use out of doors, big limitations application.Chinese patent 200580017013.9,200810152804.8 disclosed acrylic acid modified alkyd resins all because acrylic acid content low (13-20%), still are main body with the Synolac, protect light, protect look, corrosion resistance nature is suitable with Synolac.Therefore still need to improve.A kind of interpenetrating(polymer)networks vinyl resin is disclosed in Chinese patent 200710022329.8 and " interpenetrating(polymer)networks vinyl resin synthetic and to the influence of film performance " article; But only synthetic in its polyester polyol by a kind of oleic acid of ricinolic acid, because the ricinolic acid degree of unsaturation is very low, cause most acrylic monomer can't be grafted on the polyester polyol; Basically can't realize the IPN modification; And the present invention adopts several kinds of oleic acid compound, guarantees percentage of grafting, realizes real IPN modification; Therefore excellent performance especially is much better than the disclosed performance of its article in water-fast, weathering resistance performance of the present invention.
Summary of the invention
The objective of the invention is with traditional technology prepare high fullness ratio, high solid is acrylic resin modified, does not lose simultaneously weathering resistance, the corrosion resistance nature of vinyl resin again.Adopt several kinds of oleic acid compound; Prepared Synolac with suitable degree of unsaturation, acrylic resin modified with it, guaranteed percentage of grafting; Thereby become mem stage unsaturated link(age) crosslinked film forming under the effect of siccative, than unmodified acrylic resin paint better heat resistanceheat resistant after tackiness is arranged.While is owing to acrylic resin modified with the part Synolac, so the high and low VOC discharging of the vinyl resin solid of modification, more meets present environmental requirement.
Another object of the present invention provides a kind of above-mentioned acrylic resin modified preparation method.
A further object of the invention provides a kind of based on above-mentioned acrylic resin modified high fullness ratio, high solid normal temperature quick-drying automobile finish.
The object of the invention can reach through following measure:
A kind of acrylic resin modified, this resin is that 5-10% unsaturated fatty acids, 2-6% polyvalent alcohol, 3-7% diprotic acid or dibasic acid anhydride, 10-50% vinylbenzene, 40-80% acrylic ester monomer and 0.8-3% initiator form through esterification, copolymerization by mass content.The preferred group of each component becomes: 7-10% unsaturated fatty acids, 5-6% polyvalent alcohol, 5-6% diprotic acid or dibasic acid anhydride, 15-30% vinylbenzene, 55-65% acrylic ester monomer and 0.8-1% initiator; Wherein each component sum is 100%.
Wherein unsaturated fatty acids is selected from one or more in linolenic acid, tall oil acid, behenic acid, vegetable seed oleic acid, cocinic acid, ricinolic acid, the dehydrated castor oleic acid.
Polyvalent alcohol is selected from one or more in glycerine, tetramethylolmethane, TriMethylolPropane(TMP), NSC 6366, the terepthaloyl moietie.
Diprotic acid or dibasic acid anhydride are selected from one or more in phthalic anhydride, m-phthalic acid, terephthalic acid, the hexanodioic acid.
Acrylic ester monomer is selected from one or more in Bing Xisuandingzhi, Propylene glycol monoacrylate, Hydroxyethyl acrylate, vinylformic acid, methylacrylic acid, NSC 20956, Rocryl 410, the Rocryl 400.
Initiator is selected from a kind of in Diisopropyl azodicarboxylate, BPO, Di Cumyl Peroxide 99, the peroxo-dimethylbenzoyl.
Acrylic resin modified synthetic through esterification, copolymerization two step process; Its preparation method is: earlier unsaturated fatty acids, diprotic acid and polyvalent alcohol are mixed; Be warmed up to 160-200 ℃ and carry out the polycondensation esterification; Add vinylbenzene, acrylic ester monomer and initiator then, carry out copolyreaction in 110-130 ℃.
