Abstract

The invention discloses a high-wear-resistance vacuum coating hydroxyl acrylic coating as well as a preparation method and application thereof. The high-wear-resistance vacuum coating hydroxyl acrylic coating comprises a component A and a component B. The component B comprises an isocyanate curing agent, the component A comprises the following components in percentage by mass: 10%-30% of low-hydroxyl-value acrylic acid modified acrylic resin, 10%-45% of high-hydroxyl-value polyester polyol acrylic resin, 1%-10% of an adhesion promoter, 1%-5% of a nano wear-resistant material, 0.1%-2% of an auxiliary agent and 10%-50% of a diluent. According to the high-wear-resistance vacuum coating hydroxyl acrylic coating, high-hydroxyl-value polyester polyol acrylic resin is used as matrix resin and reacts with isocyanate, and a high polymer containing urethane bonds is generated. And part of acrylic acid modified low-hydroxyl-value acrylic resin and an adhesion promoter are matched, so that the adhesion of the finish paint to a metal coating layer and a material is improved, and then surface enhancement is performed through a nano wear-resistant material. Meanwhile, high impact resistance, wear resistance, tear resistance and corrosion resistance are achieved.

Description

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