Abstract

The invention relates to the PPO / HIPS material technology field, and concretely relates to a wear-resistant enhanced PPO / HIPS material and a preparation method therefor. The wear-resistant enhanced PPO / HIPS material is composed of the following raw materials, by weight, 20-40 parts of HIPS resin, 5-30 parts of PPO resin, 3-8 parts of nitrile rubber, 3-8 parts of TPU resin, 10-30 parts of glass fibers, 10-15 parts of aramid fiber, 3-10 parts of molybdenum disulfide, 3-10 parts of calcium sulfate whiskers, 1-10 parts of polytetrafluoroethylene, 0.5-1.5 parts of coupling agent, 0.5-1 part of lubricant and 0.2-0.8 part of anti-oxidant. The PPO / HIPS material has advantages of PPO such as excellent mechanical properties, heat resistance and electrical insulating properties and little creep deformation at a high temperature and the characteristic of HIPS improving the material fluidity, has high mechanical strength and modulus, and has excellent wear resistance.

Description

technical field [0001] The invention relates to the technical field of PPO / HIPS materials, in particular to a wear-resistant reinforced PPO / HIPS material and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) belongs to one of the five major engineering plastics and is a thermoplastic resin developed in the mid-1960s. PPO has the advantages of excellent mechanical properties, heat resistance, electrical insulation, and low creep at high temperatures, while PPO has low density and hygroscopicity, high strength, and good dimensional stability. However, pure PPO resin has a high glass transition temperature, poor melt fluidity, and difficult molding and processing. It needs to be processed at a high temperature of 300°C, which greatly limits its application range. In order to overcome the shortcomings of PPO and expand its application field, it must be modified. After PPO is modified by blending with high-impact-strength polystyrene (HIPS), ...
