Abstract

The invention relates to a low linear expansion coefficient polyphenyl ether/high impact polystyrene composition and a preparation method thereof. The polyphenyl ether/high impact polystyrene composition is prepared from the following raw materials: polyphenyl ether resin, high-impact polystyrene resin, mica powder, flat glass fibers, calcium sulfate whiskers, a titanate coupling agent, an ethylene-maleic anhydride-glycidyl methacrylate copolymer, 2, 2 '-(1, 3-phenylene)-dioxazoline, N, N'-bis (2, 2, 6, 6-tetramethyl-4-piperidyl)-1, 3-benzenedicarboxamide and bis (2, 6-di-tert-butyl-4-methylphenyl) pentaerythritol diphosphate. The polyphenyl ether/high-impact polystyrene composition has excellent mechanical properties and processability, low linear expansion coefficient and low warping degree, and can be applied to the fields of automobiles, aviation, electronics and electrics, household appliances and the like.

Description

technical field [0001] The invention relates to the field of materials, in particular to a low linear expansion coefficient polyphenylene ether / high impact polystyrene composition and a preparation method thereof. Background technique [0002] The existing automobile industry requires the assembly gap between different material parts to be as small as possible and has high dimensional stability, which requires polymer materials to have low warpage and linear expansion coefficient. Polyphenylene ether (PPO) has the advantages of excellent mechanical properties, heat resistance, electrical insulation, and low creep at high temperatures. At the same time, PPO has low density and hygroscopicity, high strength, and good dimensional stability. However, pure PPO resin has poor melt fluidity and difficult molding process. It needs to be modified by blending high-impact polystyrene (HIPS) to improve its molding processability, and the PPO / HIPS composition has linear expansion. The c...
