Abstract

The invention discloses a high wear-resistant vacuum coating hydroxy acrylic paint and its preparation method and application, comprising A component and B component, B component includes isocyanate curing agent, A component includes the following mass percentage: low hydroxyl value acrylic acid Modified acrylic resin 10%~30%, high hydroxyl value polyester polyol acrylic resin 10%~45%, adhesion promoter 1%~10%, nano wear-resistant material 1~5%, additives 0.1%~2 %, diluent 10% to 50%. The high wear-resistant vacuum coating hydroxyl acrylic paint of the present invention uses high hydroxyl value polyester polyol acrylic resin as the main resin, and reacts with isocyanate to form a high polymer containing urethane bonds. With some acrylic modified low-hydroxyl value acrylic resin and adhesion promoter, the adhesion of the topcoat to the metal coating layer and materials can be improved, and then the surface can be enhanced by nano wear-resistant materials. At the same time, it has high impact resistance, wear resistance, tear resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a highly wear-resistant vacuum-coated hydroxyacrylic coating. In addition, the present invention also relates to a preparation method and application of the above-mentioned high wear-resistant vacuum coating hydroxy acrylic coating. Background technique [0002] The light-curing system for mobile phone vacuum plating parts has fast curing speed, high efficiency, good wear resistance, good chemical resistance, and high hardness, but the paint film is brittle and shrinks, and it is prone to problems such as falling paint, bending and flying paint, etc. With the PU system, that is, hydroxy acrylic paint, isocyanate reacts with polyols, the reaction is mild, and high polymers containing urethane bonds are formed, which improves the flexibility of the paint film, reduces reaction shrinkage, and avoids the appearance of vacuum plating parts on the market in the past. The problem of falling pai...
