Abstract
The invention relates to an acrylate resin water latex paint and its preparation method. The invention is characterized in that the acrylate resin water latex paint mainly comprises ammonia water, butyl methacrylate, deionized water, an acrylate resin solution, an ammonium persulfate solution, etc. The acrylate resin water latex paint provided by the invention has the characteristics of high glossiness, good water resistance, capacity of allowing a film to be in an excellent state and a coating to have yellowing resistance, etc.
Description
Technical field
The present invention relates to a kind of acrylate resin water latex paint and preparation method thereof, belong to chemistry painting industry protection field.
Background technology
At present; The latex polymer that is used for water latex paint mainly comprises urethane, acrylate modified propenoate random copolymers; Usually contain the carboxylamine ester structure in the aqueous polyurethane molecular structure, with two isocyanate-frees and two no alcohol and dihydroxymethyl acid generation polycondensation, and through the preparation of self-emulsifying process; Different according to used monomer; Usually the water emulsion coating hardness of paint film by the aqueous polyurethane preparation is high, wear-resisting, scratch resistance is high, but cost is high, and also has deficiency at aspect of performances such as water tolerance and the sex change of the anti-yellow race.Also have a kind of through under the condition that exists in hydrophilic polyurethane prepolymers; Carry out the letex polymerization of acrylate monomer; Can prepare the propenoate interpenetrating(polymer)networks thereby acrylic polymer is grafted on the polyurethane chain, except keeping the excellent mechanical property of polyurethane coating film simultaneously, it has good use characteristics, mechanicalness and yellowing resistance also can to improve its water-resistant resin coating by the paint film of its preparation; But its production cost is too high, is difficult at present accepted by market.Propenoate liquid polymkeric substance makes through two kinds or multiple acrylate monomer copolymerization, prepared photocatalytic coating film excellent in stability, and the filler compatibility performance is high, and with the coated article strong adhesion, but ubiquity hardness is lower, shortcomings such as high temperature adhesive difference.
Summary of the invention
In order to solve the technical problem of above-mentioned existence; The present invention passes through special process; Reducing the coating film temperature, the hardness and the high temperature resistance to blocking of filming with raising when reducing the film forming auxiliary dosage are introduced the selfing chain gene on polymer chain; Impelling films, and self-crosslinking takes place in drying process, improves the water tolerance and the organic solvent resistance of filming; Introduce sticking power simultaneously and promote gene, further improve and film the sticking power of substrate.The objective of the invention is to provide a kind of acrylate resin solution that is used for water latex paint and preparation method thereof, it is characterized in that this acrylate resin water latex paint mainly by: ammoniacal liquor, NSC 20956, deionized water, acrylate resin solution, ammonium persulfate solution etc. are formed.
