Problems solved by technology

From the perspective of the replaced water pump, there is mainly one problem. The impeller of the water pump is deformed or even cracked. In severe cases, the impeller will break in the machine (so that the water cannot be "stirred", and the water temperature rises quickly, which poses a safety hazard to the machine) , so MPPE that can be used to manufacture water pump impellers needs to have superior mechanical properties and thermal properties

Abstract

The invention discloses a polyphenyl ether resin composition for processing a water pump impeller, which is prepared from polyphenyl ether resin, polystyrene resin, an elastomer, a compatilizer, an antioxidant, lubricant and glass fiber. The invention has the advantages of favorable mechanical properties, high dimensional stability, high heat resistance and low water absorptivity, and can be usedin the fields of machinery and engineering, such as water pump impellers and the like.

Description

technical field [0001] The invention relates to a polyphenylene ether resin composition for processing water pump impellers. Background technique [0002] Polyphenylene ether (PPE) resin has outstanding physical and mechanical properties (including mechanical properties, electrical properties, thermal properties), excellent dimensional stability and weather resistance, but its disadvantages such as high melt viscosity, low toughness, and difficult processing are limited. its practical application. Adding polystyrene (PS) resin to process PPE / PS alloy can make up for its shortcomings and realize its industrial production. It is now a mature alloy product and has been widely used in high-voltage electrical appliances, household appliances, office supplies, auto parts and Civil and other industries. [0003] PPE is a non-crystalline resin. In the usual temperature range, there is little molecular movement, no large polar groups in the main chain, no polarization of the dipole...
