High-wear-resistance acrylic resin and preparation method thereof

The invention discloses high-wear-resistance acrylic resin and a preparation method thereof. The high-wear-resistance acrylic resin is prepared from the following components in percentage by mass: 30 to 40 percent of styrene, 8 to 15 percent of hydroxypropyl ester, 8 to 15 percent of propyl butyl ester, 1 to 5 percent of 3-isocyanate propyl trimethoxy silane, 0.3 to 1.5 percent of methacrylic acid, 0.5 to 2 percent of initiator and 30 to 40 percent of xylene. According to the experiment, the optimal raw material composition and proportion are obtained through screening of a large number of experiments, the optimal synthesis process is obtained through optimization of a large number of experiments, and the conversion rate is as high as 98.8%. The acrylic resin provided by the invention has excellent wear resistance, meanwhile, a coating film has the advantages of good weather resistance, high adhesive force, high hardness, good three-proofing performance and the like, and a very good technical effect is achiev
