Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyphenylene ether / polystyrene (PPO / PS) blended alloy material, a preparation method and an application 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, because it has the following advantages: (1) Excellent physical and mechanical properties. Small density, non-toxic, high mechanical strength, good creep resistance, low molding shrinkage; (2) Excellent heat resistance. Glass transition temperature (T g ) is the highest among thermoplastics, about 210°C, and its melting point is about 260°C. It can work continuously in the range of 160-190°C. The creep resistance at high temper...
