The invention discloses a PPS/PPE composite material as well as a preparation method and application thereof, and relates to the technical field of engineering plastics. The invention provides a PPS/PPE composite material. The PPS/PPE composite material comprises the following components in parts by weight: 50-90 parts of polyphenylene sulfide resin, 5-20 parts of polyphenyl ether resin and 3-10 parts of a graft copolymer, wherein the grafted copolymer comprises a main chain and a side chain, the main chain is one of polyethylene, polypropylene, an ethylene copolymer and a propylene copolymer, and the side chain is one of polystyrene and a styrene copolymer; the pH value of the polyphenylene sulfide resin is 5 to 8. According to the invention, the PPS/PPE composite material with good heat resistance, high elongation at break and few carbonization points is prepared by using the graft copolymer of the specific main chain and side chain.
本发明公开了一种PPS/PPE复合材料及其制备方法与应用,涉及工程塑料技术领域。本发明提供了一种PPS/PPE复合材料,包括以下重量份的组分:聚苯硫醚树脂50‑90份、聚苯醚树脂5‑20份、接枝共聚物3‑10份;其中,所述接枝共聚物包括主链和侧链,所述主链为聚乙烯、聚丙烯、乙烯共聚物、丙烯共聚物中的一种,所述侧链为聚苯乙烯、苯乙烯共聚物中的一种;所述聚苯硫醚树脂的pH值为5‑8。本发明通过特定主链和侧链的接枝共聚物的使用,制备得到了耐热性好、断裂伸长率高、碳化点少的PPS/PPE复合材料。
