Abstract

The invention discloses a halogen-free flame-proof polyenyl ether composition, consisting of 30-80wt% of polyenyl ether, 10-60wt% of polystyrene, 5-25wt% of phosphorus flame retardant and 0.2-10wt% of low-boiling glass. The composition has the advantages of high flame resistance and liquidity as well as good processing property and the like, can be widely applied to materials of shells of chargers for electric products such as mobile phones and laptops, computer socket connectors, electricity meters and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant polyphenylene ether composition. Background technique [0002] Polyphenylene ether resin (PPE or PPO) is one of the five major engineering plastics, and it is also the most consumed variety among engineering plastic alloys. Because polyphenylene ether has excellent physical and mechanical properties, heat resistance and electrical insulation, low hygroscopicity, high strength, good dimensional stability, and good creep resistance at high temperatures, it is widely used in home appliances, office and Communication equipment, automobile industry and chemical industry and other fields. [0003] At present, the flame-retardant polyphenylene ether in the traditional sense uses organic phosphate as a flame retardant. Due to its low flame-retardant efficiency and poor effect, it is necessary to add more flame-retardants to achieve the ideal flam...
