Problems solved by technology

Good electrical properties in a wide temperature and frequency range, the main disadvantages are poor melt fluidity, difficult processing and molding, and low stress cracking resistance
[0004] At present, the melt fluidity, processability and stress crack resistance are mainly improved by adding plastics, resins, elastomers, etc.; but with the addition of plastics, resins, elastomers, etc., the flame retardancy of PPO will be reduced

Abstract

The invention discloses a flame retardant polyphenylene ether material, which comprises the following raw materials by weight: 60-80 parts of polyphenylene ether, 26-34 parts of impact resistant polystyrene, 0.4-0.6 part of an antioxidant, 0.4-0.6 part of an anti-dripping agent PTEE, 0.8-1.2 parts of a cross-linking agent, 1.5-2 parts of a lubricant, 2.8-3.7 parts of a compatilizer, 5- 7 parts ofan elastomer and 25-30 parts of a flame retardant. Specifically, the flame retardant is bisphenol A bis(diphenyl phosphate) and polyphenylmethylsiloxane. Through the interaction of all the substances,the flame retardant polyphenylene ether material provided by the invention has good flame retardance, stress cracking resistance, melt fluidity and processability.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a flame-retardant polyphenylene ether material. Background technique [0002] The chemical name of polyphenylene ether is poly 2,6-dimethyl-1,4-phenylene ether, referred to as PPO or PPE, also known as polyphenylene oxide or polyphenylene ether. [0003] PPO is mainly used in electronic appliances, automobiles, household appliances, office equipment and industrial machinery. PPO is non-toxic, transparent, low relative density, and has excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, flame retardancy, water resistance, water vapor resistance, and dimensional stability. It has good electrical properties in a wide temperature and frequency range, but its main disadvantages are poor melt fluidity, difficult processing and molding, and low stress cracking resistance. [0004] At present, the melt fluidity, processability and stress cra...
