Problems solved by technology

[0003] Polyphenylene ether has outstanding electrical insulation, excellent water resistance, and good dimensional stability. It is widely used in household appliances and automobile industries, but the products are prone to stress cracking, low fatigue strength, and poor melt fluidity. Difficult processing and high price limit the application in the fields of photovoltaic solar energy, aerospace and aviation with high performance requirements

Abstract

The invention discloses reinforced polyphenyl ether by using grafted block elastomer (SEBS) modification. The reinforced polyphenyl ether is characterized by comprising the following raw materials by mass percent: 60-85% of polyphenyl ether, 5-20% of high impact polystyrene, 5-20% of grafted block elastomer, 0.5-20% of compatilizer and 0.1-1% of antioxidant.

Description

technical field [0001] The invention relates to a modification of polyphenylene ether, in particular to a polyphenylene ether modified and reinforced by a grafted block elastomer (SEBS). Background technique [0002] With the development of material science and the improvement of plastic modification technology, special engineering plastics are particularly prominent among engineering plastics, and their total demand is increasing day by day. Polyphenylene ether (PP0) is the special engineering plastic with the widest application range and the largest consumption. Over the past few years, China's consumption has been increasing at a double-digit rate every year. New materials are the basis for the development of other industries. New materials are materials that are different from traditional materials and have excellent properties and special functions that traditional materials do not have (such as functional polymer materials, high-temperature superconducting materials, m...
