Abstract

The invention relates to a high-temperature-resistant and high-impact polyphenylene ether / polypropylene alloy material and a preparation method thereof; the alloy is composed of the following components in mass percentage: 20-60% polyphenylene ether, 30-60% polypropylene %, compatibilizer A1~15%, compatibilizer B1~15%, toughening agent 2~20%. The present invention also relates to the preparation method of the aforementioned high-temperature-resistant and high-impact polyphenylene ether / polypropylene alloy material: first, the raw materials are mixed in a high-speed mixer according to the above ratio, and then fed into a twin-screw extruder through a feeder, and the temperature is controlled at 180-280°C, melt extrusion, granulation, and high temperature resistant high impact polyphenylene ether / polypropylene alloy material can be obtained. The alloy material of the present invention has the advantages of good high and low temperature mechanical properties, heat resistance, insulation and easy processing and molding, and is suitable for electronic and electrical components, electric tool shells, fluid engineering components, automobile components, office components, etc., and has good application prospect.

Description

technical field [0001] The invention relates to a polyphenylene ether / polypropylene alloy material, in particular to a high-temperature-resistant 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 relatively rigid , Notch impact is very sensitive, its high melt viscosity makes it impossible for injection molding and PPO's poor oil resistance and other shortcomings greatly limit its application. However, as a general-purpose plastic, polypropylene (PP) is poor in 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 polyphenyl...
