Abstract

The invention relates to a grease-resistant high-impact polyphenylene oxide (PPO) composite material. The PPO composite material is prepared from the following raw materials in parts by weight: 40-50parts of PPO resin, 30-45 parts of PA12 resin, 6-10 parts of compound components and 10-14 parts of a compatilizer, wherein the compound components comprise acrylonitrile-styrene (AS) resin, polytetrafluoroethylene and calcium sulfate whiskers. The PPO composite material disclosed by the invention has relatively high impact resistance and good grease resistance.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a grease-resistant high-impact PPO composite material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) resin has the advantages of good mechanical properties, chemical stability and heat resistance. The products can be used continuously in high temperature or high humidity environment while maintaining good dimensional stability and mechanical strength. Applications in mechanical and electrical fields are becoming more and more extensive. However, PPO also has certain deficiencies. The most prominent disadvantages are its high melt viscosity and poor formability. Under the stress of injection molded products, mineral oil, ketones, and ester solvents will cause stress cracking, which is extremely difficult. This greatly limits the application of the material in other fields. [0003] Chinese patent 201310102133.5 discloses a PPO / PA alloy ...
