Abstract

The invention belongs to the field of the high polymer materials and specifically relates to a polypropylene modified polyphenyl ether material for automobile plastic parts. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 20-24 parts of polypropylene, 1-2 parts of poly dihydropyridine, 5-7 parts of epoxy soybean oil, 5-8 parts of calcium carbonate powder, 12-15 parts of talcum powder, 8-12 parts of bentonite powder, 1-2 parts of antioxidant 168, 1-2 parts of nano-titanium dioxide, 4-6 parts of methyl methacrylate and 12-15 parts of auxiliaries. The polypropylene modified polyphenyl ether material integrates the advantages of the raw materials such as polyphenyl ether and polypropylene, and is modified by using the raw materials such as the bentonite powder and the talcum powder, so that the mechanical properties of the material are improved; the prepared material is firm and flexible, resistant to weather ageing, safe and flame-retardant, and has excellent electrical properties and long service life, and thus can be widely applied to manufacturing of various automobile plastic parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polypropylene-modified polyphenylene ether material for 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 various parts of aut...
