Abstract

The invention discloses a high-strength high-transmittance acrylic plate. The high-strength high-transmittance acrylic plate is prepared from, by weight, 0.5% of methyl cyanoformate, 1% of chloromethyl acetate, 1.2% of dimethacrylate diethanol, 1.5% of fluorite powder, 1-2% of nano calcium carbonate, 1.8% of nano graphene, 8% of nano silicon carbide, 0.5% of maleic anhydride, 0.5% of trimethoxysilane, 0.5% of magnesium stearate, 15-20% of glass fibers and acrylic resin monomers, wherein the total weight percentage is 100%. The acrylic resin monomers are formed from a mixture of polycarbonate resin and polymethyl methacrylate, wherein a weight ratio of polycarbonate resin to polymethyl methacrylate is 2:9; the glass fibers are irregularly intertwined to form a honeycombed sheet structure. The acrylic plate prepared according to the method is high in strength, toughness and light transmittance, and the preparation method is simple in process and quite suitable for industrial production.

Description

technical field [0001] The invention relates to a high-strength and high-transparency acrylic plate and a preparation method thereof, belonging to the technical field of organic glass. Background technique [0002] Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic), and its chemical name is polymethyl methacrylate. Acrylic is a polymer thermoplastic material developed earlier, and its processing and molding are more convenient. The molding methods of acrylic materials mainly include casting molding and extrusion molding. After molding, acrylic materials can also be softened by reheating. Acrylic has good transparency and light transmittance, and its light transmittance can reach 92%. It has good chemical stability and weather resistance, and is highly adaptable to the natural environment. However, its toughness and light transmittance are slightly insufficient in high-demand special use environments, which directly affects the use...
