Abstract

A fire-retardant acrylic diamond is prepared from, by weight, 50-70% of acrylic resin monomer, 0.25-1% of a compatilizer, 0.1-0.5% of a curing agent, 0.1-2% of a compound antioxidant and the balance organic filler, wherein the total weight percent is 100%. The acrylic resin monomer is formed by a mixture of polycarbonate resin and polymethyl methacrylate, and a weight ratio of polycarbonate resin to polymethyl methacrylate is 5:1-3.5.

Description

technical field [0001] The invention relates specifically to a flame-retardant acrylic diamond and a preparation method thereof. Background technique [0002] Molded acrylic diamonds are prepared by mixing inorganic fillers such as aluminum hydroxide into acrylic resins. This acrylic diamonds have various excellent functions and properties, such as appearance, soft feel, etc., but due to the characteristics of the acrylic resin itself, the product's There are certain defects in strength and heat resistance. Contents of the invention [0003] In order to solve the above problems, the present invention provides a flame-retardant acrylic diamond: [0004] A flame-retardant acrylic diamond comprises the following components in parts by weight: [0005] Acrylic resin monomer 50-70%; [0006] Compatibilizer 0.25-1%; [0007] Curing agent 0.1-0.5%; [0008] Compound antioxidant 0.1-2%; [0009] Inorganic filler to 100%; [0010] The acrylic resin monomer is composed of a m...
