Abstract

The invention relates to a high-temperature-resistant high-impact-resistant polyphenylether / polypropylene alloy material and a preparation method thereof. The alloy is composed of the following components in percentage by mass: 20-60% of polyphenylether, 30-60% of polypropylene, 1-15% of compatilizer A, 1-15% of compatilizer B and 2-20% of toughener. The invention also relates to a preparation method of the high-impact-resistant polyphenylether / polypropylene alloy material, which comprises the following steps: proportionally mixing the raw materials in a high-speed mixer, adding into a double screw extruder by a feeder, and carrying out melt extrusion for granulation at 180-280 DEG C to obtain the high-impact-resistant polyphenylether / polypropylene alloy material. The alloy material provided by the invention has the advantages of favorable high / low-temperature mechanical properties, high heat resistance, favorable electric insulativity and the like, is easy for molding, is suitable for electronic and electrical components, electric tool housings, fluid engineering parts, automobile parts, office parts and the like, and has favorable application prospects.

Description

Technical field [0001] The invention relates to a polyphenylene ether / polypropylene alloy material, in particular to a high temperature and high impact polyphenylene ether / polypropylene alloy material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPE or PPO for short) is a high-performance thermoplastic engineering plastic with good mechanical properties, chemical stability, dielectric properties, heat resistance and flame retardancy, but the PPO molecular chain is more rigid Large, notched impact is very sensitive, its high melt viscosity makes it impossible to injection molding and the poor oil resistance of PPO greatly restrict its application. However, polypropylene (PP) as a general-purpose plastic has poor physical and mechanical properties and heat resistance, but has obvious advantages in processability, oil resistance, acid and alkali corrosion resistance, and cost. Therefore, by preparing polyphenylene ether / polypropylene Alloys c...
