Abstract

The invention relates to the technical field of manufacturing of polymer materials, and discloses a fluorine-free abrasion-resistant polymer composite and a preparation method thereof. The fluorine-free abrasion-resistant polymer composite comprises the following raw materials in parts by mass: engineering thermoplastic and abrasion-resistant fluorine-free graft copolymer based on the ratio of (30-95): (5-70). The fluorine-free abrasion-resistant polymer composite further comprises reinforced fibers, wherein the ratio of engineering thermoplastic to abrasion-resistant fluorine-free graft copolymer to reinforced fibers is (30-90): (5-30): (5-60). The fluorine-free abrasion-resistant polymer composite further comprises a lubricating agent, a stabilizing agent and an antioxidant, wherein theratio of engineering thermoplastic to abrasion-resistant fluorine-free graft copolymer to reinforced fibers to (lubricating agent, stabilizing agent and antioxidant) is (30-89.9): (5-30): (5-60): (0.1-2). According to the fluorine-free abrasion-resistant polymer composite, PC, POM, PA and SAN grafted high molecular weight high density polyethylene is used as a material; polytetrafluoroethylene isnot added, so that the composite does not contain fluorine; an abrasion resisting additive is high in compatibility to substrate resin; the lubricating performance and the abrasion resistance are outstanding, the mass is light, and the appearance uniformity is improved under the same adding ratio; and moreover, the mechanical performance of the substrate resin is improved.

Description

technical field [0001] The invention relates to the technical field of polymer material manufacturing, in particular to a fluorine-free wear-resistant polymer composite material and a preparation method thereof. Background technique [0002] Among the existing wear-resistant modified polymer materials, polytetrafluoroethylene PTFE micropowder is commonly used as a wear-resistant modifier, but it will cause the material to contain fluorine, the specific gravity is high, and the mechanical properties are low. related scaling problems. In addition, on October 27, 2017, the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization was initially compiled for reference, and polytetrafluoroethylene was listed in the list of three types of carcinogens. All of these make the use of such wear-resistant modified polymer materials subject to certain restrictions. [0003] At present, more and more wear-resistant modified polymer m...
