Abstract

The invention discloses a rosin modified high-toughness polyester board, which is prepared from the following raw materials in parts by weight: 200-260 parts of methyl methylcellulose methyl ester, 6-8 parts of dicumyl peroxide, 13-20 parts of ammonium polyphosphate, 3-5 parts of aluminum stearate, 0.1-0.3 part of octyl isothiazolinone, 2-4 parts of ricinoleic acid, 20-30 parts of polytetrafluoroethylene wax, 1-2 parts of ammonium persulfate, 10-15 parts of methyl cellulose, 10-18 parts of antimonous oxide and 20-30 parts of rosin. According to the polyester board, the dispersion compatibilityof methyl cellulose and rosin between finished products is effectively improved, the mechanical property of the finished products is improved, and the bonding strength of the finished product board is improved, so that the fracture resistance is improved. The polyester board is low in raw material cost, and the added ammonium polyphosphate, antimony trioxide and the like have certain fireproof performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a rosin-modified high-toughness polyester board and a preparation method thereof. Background technique [0002] Polymethyl methacrylate, polymers obtained by polymerization of acrylic acid and its esters are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethacrylate methyl is the most widely used, polymethylmethacrylate Methyl acrylate resin is a non-toxic and environmentally friendly material, which can be used to produce tableware, sanitary ware, etc. It has good chemical stability and weather resistance. Polymethyl methacrylate resin is not easy to produce sharp fragments when it is broken. The United States, Japan Countries and regions such as China have made mandatory regulations in the law that polymethyl methacrylate resin must be used for glass in primary and secondary s...
