Abstract

The invention belongs to the technical field of high-molecular materials, and relates to a polyphenyl ether / polypropylene copolymer blended alloy material and a preparation method thereof. The blended alloy material is prepared from the following composition in parts by weight: 20-60 parts of polyphenylene oxide (PPO), 20-60 parts of polypropylene copolymer (PP), 5-15 parts of a compatilizer, 5-15 parts of a flexibilizer, 0.2-0.6 part of an anti-oxidant, and 0.2-0.5 part of a lubricant. The added PP helps to improve the processing performance of PPO and reduce cost to a relatively large degree; additionally, PPO is blended with PP, so that the solvent resistance and the impact resistance of PPO are improved, the surface luster of PPO is improved, and the material density is reduced; and finally, PPO is firstly pretreated with maleic anhydride and then is blended with PP, so that the compatibility of PPO and PP is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyphenylene ether / polypropylene copolymer (PPO / PP) blend alloy material and a preparation method thereof. Background technique [0002] With the progress of society and the development of science and technology, people's life is becoming more and more convenient, and at the same time, people are paying more and more attention to the environment. Polyphenylene oxide (PPO) is a thermoplastic engineering plastic with excellent performance, which has low density, non-toxicity, good creep resistance, low molding shrinkage, glass transition temperature (T g ) High, good electrical performance and so on. Among them, high creep resistance is its most prominent feature, so PPO is especially suitable for making industrial structural parts that withstand long-term loads. However, PPO also has some disadvantages, such as poor solvent resistance, prone to stress cracking of prod...
