Waterproof temperature-resistant modified polyphenyl ether material for automotive plastic part

Abstract

The invention belongs to the field of high molecular materials and particularly relates to a waterproof temperature-resistant modified polyphenyl ether material for an automotive plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 12-15 parts of silicon carbide, 7-9 parts of aluminum oxide, 7-9 parts of dipropylene glycol dibenzoate, 3-5 parts of stearic acid, 2-3 parts of triallyl isocyanurate, 5-8 parts of barium sulfide, 3-5 parts of zinc sulfide, 5-8 parts of C5 petroleum resin, 1-2 parts of vinyl triethoxy silane, 1-2 parts of accelerant DM and 12-15 parts of assistant. The material provided by the invention combines the advantages of the raw materials such as polyphenyl ether and C5 petroleum resin and modifies the raw materials such as silicon carbide, so that the obtained material has good processing and mechanical performances. The prepared material prepared is great in strength, water-penetration and oil-penetration resistant, thermal-aging resistant, low-temperature impact resistant, good in electric insulating performance, and safe and reliable to use, and can be widely applied to preparing various automotive plastic parts.
