Polyphenylene sulfide composite material and preparation method thereof

The invention discloses a polyphenylene sulfide composite material. The polyphenylene sulfide composite material comprises the following compositions: 100 parts by weight of polyphenylene sulfide, 10-80 parts by weight of teflon, 0.1-10 parts by weight of a nucleating agent, and 0.1-10 parts by weight of a silane coupling agent. The silane coupling agent is a silane coupling agent containing an epoxy group, and the particle dimension of teflon is 10 mu m-30 mu m. The polyphenylene sulfide and teflon composite material is prepared by utilizing the advantages that polyphenylene sulfide is high in strength and teflon is low in friction coefficient and small in abrasion loss. The composite material has the friction coefficient of 0.10-0.20 and the abrasion loss of 0.15-0.30 mg, and is widely applicable to fields of automobiles and household electric appliances.
