Abstract

The invention discloses a polyphenyl ether alloy composition for processing an automobile spare tire cover which is prepared from polyphenyl ether resin, polystyrene resin, elastomer, a plasticizer, a rheology accelerant and an antioxygen. On the basis that the mechanical property of the polyphenyl ether alloy resin material is maintained, tenacity and mobility of the polyphenyl ether alloy resin material are improved, so the polyphenyl ether alloy resin material can well meet the injection molding requirement of the automobile spare wire cover.

Description

technical field [0001] The invention relates to a polyphenylene ether alloy composition used for processing automobile spare tire covers, belonging to the field of polymer alloys. technical background [0002] Polyphenylene ether (PPE) resin has outstanding physical and mechanical properties, excellent dimensional stability, weather resistance and self-flame retardant properties, and has been widely used in electronic appliances, household appliances, office supplies, communication photovoltaics and other industries. In recent years, PPE alloy materials have been more and more used in the automotive field, but due to its defects in fluidity and toughness, it has been limited in the application of large automotive parts, such as car spare tire covers, Common materials cannot be filled and parts are prone to cracking when impacted. Contents of the invention [0003] The product of the present invention is a polyphenylene ether alloy composition suitable for automobile spare...
