Abstract

The invention relates to a high-hardness wear-resistant ultra high molecular weight polyethylene (UHMW-PE) product and a preparation method thereof, belongs to the field of UHMW-PE materials, and aimsto solve the technical problems of unsatisfactory effects and high cost during improvement on the hardness and wear resistance of UHMW-PE. The high-hardness wear-resistant UHMW-PE plastic product provided by the invention is prepared from the following raw materials in percentage by weight: 65.2 to 97 percent of UHMW-PE, 0 to 0.4 percent of coupling agent, 0 to 4 percent of dispersing agent, 1 to30 percent of high-titanium blast furnace slag micro powder, 0 to 0.2 percent of antioxidant and 0 to 0.2 percent of anti-ultraviolet agent. Firstly, mixing the blast furnace slag micro powder and the coupling agent with stirring; then, uniformly mixing the dispersing agent, the antioxidant and the anti-ultraviolet agent; and finally, performing direct machine shaping on a mixture and the UHMW-PEto form an engineering plastic product. According to the invention, the method is simple and easy to operate; the production cost is lower; and a prepared UHMW-PE plate can be up to 75HD in hardnessand is less than 0.13 in friction coefficient.

Description

technical field [0001] The invention belongs to the field of ultra-high-molecular-weight polyethylene materials, and in particular relates to high-hardness and wear-resistant ultra-high-molecular-weight polyethylene products and a preparation method thereof. Background technique [0002] Ultra High Molecular Weight Polyethylene (UHMW-PE) is the engineering plastic with the best comprehensive performance, and its wear resistance, impact resistance, corrosion resistance, self-lubrication, and impact energy absorption are the best among existing plastics. . Therefore, UHMW-PE has been widely used in textile, papermaking, packaging, transportation, machinery, chemical industry, mining, petroleum, agriculture, construction, electrical, food, medical, sports and other fields, and has begun to enter conventional weapons, ships, automobiles, etc. field. With the gradual development of industrial manufacturing level, higher requirements are put forward for the physical and mechanic...
