Abstract

Belonging to the technical field of high polymer materials, the invention discloses a polyphenylene oxide / polystyrene blend alloy material, its preparation method and application. The polyphenylene oxide / polystyrene blend alloy material provided in the invention is prepared from the following components by weight: 36-90 parts of polyphenylene oxide, 10-50 parts of polystyrene, 0.2-0.7 part of a lubricant, 0.2-0.5 part of an antioxidant and 7.1-46.1 parts of an assistant. The preparation method of the polyphenylene oxide / polystyrene blend alloy material consists of the steps of: weighing 36-90 parts of polyphenylene oxide, 10-50 parts of polystyrene, 0.2-0.7 part of the lubricant, 0.2-0.5 part of the antioxidant and 7.1-46.1 parts of the assistant, mixing them uniformly at a high speed by a high-speed mixing machine, then pouring the mixture into a screw extruder, and carrying out strand pelletizing by the screw extruder, thus obtaining the product. The invention also discloses application of the polyphenylene oxide / polystyrene blend alloy material as an extrusion type profile material. The polyphenylene oxide / polystyrene blend alloy material provided in the invention can reduce cost and save energy, and realizes the purpose of substituting plastics for steel.

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...
