Abstract

The invention belongs to the field of high molecular materials, and in particular relates to a temperature-resistant polyvinyl chloride modified polyphenyl ether material for automobile plastic components. The material is prepared from the following raw materials in parts by weight: 100 parts of polyphenyl ether, 10-12 parts of E-12 epoxy resin, 4-7 parts of ammonium dihydrogen phosphate, 1-2 parts of borax, 14-18 parts of calcium carbonate powder, 2-3 parts of diphenylmethane diisocyanate, 6-8 parts of aluminum oxide, 1-3 parts of LK-640 boric acid ester coupling agent, 3-4 parts of polyester silicon oil, 12-16 parts of polyvinyl chloride, 1-2 parts of wood flour, 3-4 parts of stearic acid and 12-15 parts of additives. The material combines the advantages of raw materials such as the polyphenyl ether, the polyvinyl chloride and the E-12 epoxy resin, the property of a conventional polyphenyl ether material is improved, the polyphenyl ether material is good in machining property and mechanical property, the prepared material is high in strength, good in toughness, thermal aging resistant, low-temperature impact resistant, good in chemical stability, flame-retarding, safe and reliable, and can be widely used for manufacturing various automobile plastic components.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a temperature-resistant polyvinyl chloride 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 u...
