Abstract

The invention provides a modified polyphenyl ether material, which has lower cost, good flame retardant property and good mechanical property at the same time. The modified polyphenyl ether material consists of the following raw materials in part by weight: 60 to 90 parts of polyphenyl ether, 5.6 to 8.4 parts of high impact polystyrene, 9 to 13.6 parts of flame retardant, 4.8 to 7.2 parts of toughening agent, 0.4 to 0.6 part of antioxidant, 0.16 to 0.24 part of light stabilizer and 0.48 to 0.72 part of toner. The flame retardant is phosphate flame retardant or the flame retardant compounded by phosphate flame retardant and nitrogen flame retardant; the flame retardant is bisphenol A bi(diphenyl phosphate); the toughening agent is SEBS or SBS; the light stabilizer is zinc oxide and / or sulfur oxide; and the toner is colorant such as carbon black powder.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a modified polyphenylene ether composition suitable for raw materials of solar junction boxes. Background technique [0002] Polyphenylene ether resin (PPO) is a thermoplastic general engineering plastic with excellent physical and mechanical properties, heat resistance and electrical insulation. Its moisture absorption is low, its strength is high, its dimensional stability is good, and its creep resistance at high temperatures is all thermoplastic The best among engineering plastics, but due to poor fluidity of PPO, it is usually blended and modified with other plastics. Modified polyphenylene ether resin (PPO) has excellent comprehensive properties and molding processing properties, so it has a wide range of applications in the fields of electronics, electrical appliances, household appliances, office automation machinery, automobiles and other transportation machinery, building ma...
