Abstract

The invention relates to a ceramic polymer anti-abrasion polypropylene composite material. The ceramic polymer anti-abrasion polypropylene composite material is prepared from the following raw material components: polypropylene, a ceramic polymer, metal alloy powder, polysulfide rubber, epoxy octyl stearate, diisodecyl pentaerythritol diphosphite and zinc stearate, wherein the ceramic polymer is prepared by virtue of the reaction of silicic acid, titanic acid, tungstic acid, molybdic acid, gallic acid, dimethylaminoethyl acrylate, acrylamide and benzoin methyl ether, the metal alloy powder is prepared by virtue of the reaction of zinc stearate, calcium stearate, copper stearate, 1-ethyl-3-methylimidazolium ethylsulfate and modified potassium powder, and the modified potassium powder is prepared by virtue of the reaction of potassium powder, 1-ethyl-3-methylimidazolium ethylsulfate, sodium dodecyl benzene sulfonate and methyl methacrylate. The ceramic polymer anti-abrasion polypropylene composite material has excellent abrasion resistance and mechanical strength.

Description

technical field [0001] The invention relates to a ceramic polymer wear-resistant polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene is one of the five general-purpose plastics, which has the advantages of low density, flex resistance, high strength, good insulation, and corrosion resistance. The disadvantages are poor low-temperature impact performance, easy aging, and large molding shrinkage. Polypropylene can be used in various fields such as automobile bumpers, packaging materials, pipes, sheets, rods, and daily necessities. [0003] At present, the wear resistance and mechanical strength of polypropylene materials need to be further improved. The invention uses polypropylene, ceramic polymer, metal alloy powder, polysulfide rubber, and epoxy octyl stearate to prepare ceramic polymer wear-resistant polypropylene composite materials, which are prepared by extrusion, injection molding, molding, blow molding and o...
