Abstract

The invention belongs to the field of the high polymer materials and specifically relates to a waterproof bentonite 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, 2-3 parts of parachlormetaxylenol, 8-10 parts of propyl methacrylate. 3-5 parts of stearic acid, 3-4 parts of straw ash, 2-3 parts of lanthanum oxide, 12-15 parts of bentonite, 2-4 parts of kaoline, 3-5 parts of flue gas desulfurization gypsum, 6-9 parts of epoxy linseed oil, 1-2 parts of accelerator M and 12-15 parts of auxiliaries. The polyphenyl ether is modified by using raw materials such as bentonite, so that the properties of the polyphenyl ether material are improved, and consequently, the polyphenyl ether material has excellent processability and mechanical property; the prepared material is high in strength, firm, wearable, waterproof and moisture-proof, easy to dye, can resist chemical solvent corrosion, is beautiful, durable, and safe and reliable to use, and thus can be widely applied to manufacturing of various automobile plastic parts, particularly plastic parts for automobile parts such as window wipers, roofs and doors.

Description

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