Problems solved by technology

Although polyphenylene ether alloy materials have excellent heat resistance and mechanical strength, they also have some fatal defects, such as poor fluidity, poor oil resistance, and severe stress cracking.
For relatively large parts of automobiles, high fluidity is required without stress cracking after spraying, which has always been a major challenge in the field of polyphenylene ether resin application

Abstract

The invention belongs to the field of high-polymer alloy materials, and particularly relates to a polyphenyl ether resin alloy material used for processing automobile spare tire covers and a preparation method of the polyphenyl ether resin alloy material. The polyphenyl ether resin alloy material is prepared by, by weight, 20-40 parts of polyphenyl ether resin, 50-80 parts of polystyrene resin, 1-3 parts of polyolefin, 1-8 parts of elastomer, 1-15 parts of flame retardant, 0.05-0.30 part of lubricant, 1-3 parts of inorganic filler, 3-8 parts of grafting bodies, and 0.10-0.50 part of antioxidant. By adjusting formula composition and selecting proper process and extruding conditions, the problem about mobility of the polyphenyl ether resin alloy material is solved. The polyphenyl ether resin alloy material has high mobility and no stress cracking after spraying, is capable of sufficiently meeting operating requirements of the application field of automobile parts and quite applicable to raw materials for automobile spare tire covers.

Description

Technical field [0001] The invention belongs to the field of polymer alloy materials, and specifically relates to a polyphenylene ether resin alloy material, a preparation method and application thereof. Background technique [0002] Polyphenylene ether resin has many excellent properties, such as mechanical properties, hydrolysis resistance, acid and alkali corrosion resistance, heat resistance, dimensional stability, etc. Its products are widely used in electronic appliances, auto parts, water treatment equipment, Chemical industry and other fields. Although polyphenylene ether alloy materials have excellent heat resistance and mechanical strength, they also have some fatal defects, such as poor fluidity, poor oil resistance, and severe stress cracking. For the relatively large parts of automobiles, high fluidity is required, and no stress cracking occurs after spraying. This has always been a major challenge in the application of polyphenylene ether resin. Summary of the inv...
