Abstract

The invention belongs to the field of high molecular materials, and particularly relates to a heat-resisting flame retardant modified polyphenyl ether material for automotive plastic parts. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 12-15 parts of poly(4-methyl-1-pentene), 4-6 parts of stearic acid, 9-12 parts of zinc borate, 6-9 parts of magnesium aluminate, 10-12 parts of antimony trioxide, 1-2 parts of glycerol triacetate, 1-2 parts of sarcandra glabra essential oil, 5-7 parts of dioctyl phthalate, 2-3 parts of tricresyl phosphate, 6-9 parts of pentaerythritol stearate and 12-15 parts of aids. The heat-resisting flame retardant modified polyphenyl ether material combines the advantages of the raw materials such as the polyphenyl ether and the poly(4-methyl-1-pentene); the prepared material has high strength, heat resistance, chemical corrosion resistance, oil resistance and good electrical insulating property, is easy to process and mold, lightweight and safe and reliable to use, can be widely used for manufacturing various automotive plastic parts and is particularly suitable for manufacturing of parts such as automotive oil delivery pipes and brake pipes.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a modified polyphenylene ether material for heat-resistant and flame-retardant automobile plastic parts and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is one of the five major engineering plastics, with excellent physical and mechanical properties, heat resistance and electrical insulation, low moisture absorption and excellent creep resistance. It is widely used in auto parts and other fields. PPO is an amorphous polymer material. Its melt viscosity is very high and its fluidity is very poor. If it is not modified, it cannot be used because it cannot be processed. [0003] In order to improve the performance of polyphenylene oxide (PPO) materials and broaden the scope of use of materials, it is necessary to improve the formula of polyphenylene oxide (PPO) materials and modify the materials so that they can be widely used in...
