Abstract

The present invention discloses one kind of polyphenyl thioether / polyamide composite material and its preparation process. The polyphenyl thioether / polyamide composite material is prepared with polyphenyl thioether 23-69.3 wt%, polyamide 10-30 wt%, glass fiber 20-40 wt%, heat stabilizer 0.2-2 wt%, silane coupler 0.1-2 wt%, processing lubricant 0.2-2 wt% and crystallization promoter 0.1-1 wt%. The polyphenyl thioether / polyamide composite material has high shock toughness, simple preparation process and low cost.

Description

[technical field] [0001] The invention relates to a polyphenylene sulfide resin material, in particular to a polyphenylene sulfide / polyamide composite material and a preparation method thereof. [Background technique] [0002] Polyphenylene sulfide resin (PPS), also known as polyphenylene sulfide, has good comprehensive properties, high temperature resistance, corrosion resistance, radiation resistance, non-combustibility, and good mechanical and electrical properties, so polyphenylene sulfide is The material of choice in the fields of electronics and electrical appliances. However, polyphenylene sulfide resin (PPS) has low impact strength and poor bending resistance; moreover, PPS has high melt viscosity and poor processing performance; at the same time, its cost is higher than that of general engineering plastics. These shortcomings limit the application range of polyphenylene sulfide resin in the field of mid-end products. Aiming at the defects in the performance of poly...
