Abstract

The invention discloses a halogen-free flame retardant polyphenyl ether / polystyrene alloy material. The material comprises the following components by weight: 37-90 parts of polyphenyl ether, 10-50 parts of polystyrene, 5-20 parts of a flame retardant, 0.2-0.5 parts of an antioxidant and 5.1-35.1 parts of an assistant. The invention also discloses a preparation method of the halogen-free flame retardant polyphenyl ether / polystyrene alloy material. The PPO / PS alloy material provided by the invention has advantages of excellent property, low cost and energy saving, and can realize steel substitution by plastic. The added halogen-free flame retardant endows the alloy with good flame retardancy, is friendly to the environment, and does not cause secondary pollution. Besides, the material forming process is simple, and saves processing cost. Further, a section bar produced from the PPO / PS alloy material has wide application, and can be used for parts in special electronic and electrical appliances and large equipment, due to the advantages of good flame resistance, corrosion resistance, insulation, good strength and toughness, light resistance and light weight.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant polyphenylene ether / polystyrene (PPO / PS) 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, 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...
