Antimicrobial low-warpage low-flash PPS composite material and preparation method thereof

The invention discloses an antimicrobial low-warpage low-flash PPS composite material and a preparation method thereof. The material is prepared from, by weight, 31.5-48% of PPS resin, 6-12% of PPE resin, 40-45% of glass fibers, 8-12% of antimicrobial agent, 0.5-1% of nucleating agent, 0.4-0.5% of antioxidant and 0.5-0.6% of lubricating agent. An engineering plastic, namely PPS, serves as a main body, the PPE resin, the glass fibers, the antimicrobial agent, the nucleating agent the antioxidant and the lubricating agent are added, the raw materials are mixed together and melted through a double-screw extruder, and then the antimicrobial low-warpage low-flash PPS composite material which is capable of meeting the antimicrobial requirements of household appliances is prepared. The material has the advantages of being antimicrobial, low in warpage and low in flash on the basis of ensuring the original excellent mechanical performance, heat resistance, fire resistance and electrical performance of PPS. 本发明公开了种抗菌型
