Abstract

The invention belongs to the field of polymer materials, and particularly relates to a waterproof modified polyphenylene oxide material for an automobile plastic part. The material is prepared by the following raw materials in parts by weight: 100 parts of polyphenyl ether, 1-2 parts of silane coupling agent KH-550, 4-6 parts of resorcinol double (diphenyl organic phosphate), 4-6 parts of phosphotriester-(2-chloride propyl), 5-7 parts of zinc dihydrogen phosphate, 3-4 parts of zinc borate, 12-15 parts of pyrophosphoric acid zinc, 3-4 parts of stearic acid, 1-2 parts of urotropine, and 12-15 parts of an auxiliary. According to the invention, components of zinc dihydrogen phosphate, zinc borate, pyrophosphoric acid zinc, and the like are added in the raw materials; properties of the conventional polyphenyl ether materials are modified; favorable processability and mechanical property are provided; the prepared material is solid and flexile, waterproof, damp resistant, heat ageing resistant, chemical corrosion resistant, firm, and durable, and can be widely used for manufacturing various automobile-used plastic parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a waterproof 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 automo...
