Abstract

The invention discloses a flame-retardant and anti-static polycarbonate composite material for sockets and a preparation method of the composite material. The composite material is prepared from raw materials in parts by weight as follows: 80-100 parts of polycarbonate, 20-30 parts of polyvinyl chloride, 8-10 parts of SEBS, 2-4 parts of tributyl citrate, 3-5 parts of aluminum-doped nano-zinc oxide, 5-10 parts of zinc molybdate, 10-15 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 3-5 parts of brominated epoxy resin, 5-8 parts of vinyltriethoxysilane, 14-18 parts of calcined kaolin, 6-7 parts of barium metaborate, 3-4 parts of bis(2-hydroxy-4-methoxyphenyl)methanone, 8-10 parts of hexagonal boron nitride, 8-10 parts of ethylene terephthalate, 6-8 parts of fumed silica, 35-45 parts of colemanite powder, 4-6 parts of sodium metaantimonite, 12-14 parts of ammonium polyphosphate, 5-9 parts of pentaerythritol stearate and 7-8 parts of dimethicone. The polycarbonate composite material has excellent flame-retardant and anti-static properties, good mechanical properties, high strength, good heat resistance and chemical resistance and excellent electric properties and is low in cost, wide in application range and easy to popularize.

Description

technical field [0001] The invention relates to a polycarbonate composite material, in particular to a flame-retardant and antistatic polycarbonate composite material for a socket and a preparation method thereof. Background technique [0002] Composite materials are materials with new properties composed of two or more materials with different properties through physical or chemical methods on a macroscopic (microscopic) level. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. [0003] Polycarbonate is a thermoplastic engineering plastic with excellent comprehensive properties. It has outstanding impact resistance, good creep resistance and dimensional stability, and can maintain high mechanical strength in a high temperature range. It is non-toxic and dielectric With excellent...
