Abstract

The invention discloses a temperature-resistant wear-resistant high-quality acrylic board, belonging to the field of high-polymer materials. The temperature-resistant wear-resistant high-quality acrylic board is prepared from polymethyl methacrylate, ethyl cyanoacrylate, 3-trifluoroacetoxypropyltrimethoxy silane, methylchloroformate, ethoxylated trimethylolpropane triacrylate, acrylamide, 2-hydroxypropyl acrylate, dioctyl ester, tert-butyl peroxybenzoate, modified nano alumina, phthalic anhydride, methyltriethoxysilane, potassium pyrophosphate, methyl cellulose and microcrystalline cellulose. According to the characteristics of the polymethyl methacrylate, organic matters and inorganic matters in proper proportions are added to perform modification treatment so as to obviously enhance the comprehensive properties. The impact strength at normal temperature can reach 30 kJ / m<2> or above, the tensile strength can reach 90 MPa or above, the high temperature resistance is 140 DEG C, the surface Rockwell hardness is up to 100 or above, and the wear resistance is favorable, thereby well widening the application range of the acrylic board.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a high-quality acrylic plate with temperature resistance and wear resistance and a preparation method thereof. Background technique [0002] Acrylic, whose chemical name is polymethyl methacrylate, is as transparent as glass.
