Problems solved by technology

Compared with other polymer materials, polycarbonate itself has certain flame retardant properties, and has a certain degree of char formation when burning, but polycarbonate has low flame retardant properties and heat resistance. When used in televisions, computers, etc. In fields with high flame retardancy and high heat resistance requirements, such as transformer coils, auto parts, and building materials, the heat resistance and flame retardancy are still not ideal, and polycarbonate still needs to be modified

Abstract

A preparing method of an environmental friendly flame-retardant polycarbonate composite material is disclosed. The method includes mixing nanometer zinc oxide, nanometer titanium dioxide, nanometer aluminium hydroxide, glass fibre, kaolin, nanometer zinc stannate, ferrocene, zinc molybdate, basic sodium aluminium carbonate, calcium stearate, zinc stearate and a silane coupling agent KH-540 to obtain a modified filler; melting and extruding polyvinyl butyral, polyvinylidene fluoride, octafluoro-diphenyl diglycidylether, styrene-acrylonitrile copolymer, melamine resin and the modified filler in a twin-screw extruder to obtain dispersed master batch; adding polycarbonate, the dispersed master batch, tris(2,4-diisobutyl) phosphate, hexaphenoxycyclotriphosphazatriene, potassium perfluorobutanesulfonate, bisphenol A bisphthalonitrile, a plasticizer and an oxidant into a twin-screw extruder, melting and extruding. The composite material prepared by the method is good in heat resistance and excellent in flame retardance.

Description

technical field [0001] The invention relates to the technical field of polycarbonate, in particular to a preparation method of an environmentally friendly heat-resistant and flame-retardant polycarbonate composite material. Background technique [0002] Polycarbonate is one of the five major engineering plastics and the only transparent engineering plastic. Because of its excellent comprehensive performance, it has been widely used in construction, electronic appliances, aerospace, automobiles, optical discs and other fields. Compared with other polymer materials, polycarbonate itself has certain flame retardant properties, and has a certain degree of char formation when burning, but polycarbonate has low flame retardant properties and heat resistance. When used in televisions, computers, etc. In fields with high flame retardancy and high heat resistance requirements, such as transformer coils, auto parts, and building materials, the heat resistance and flame retardancy are ...
