Preparation method of wear-resistant high polymer material

Abstract

The invention relates to a preparation method of a wear-resistant high polymer material. The preparation method comprises steps as follows: (1), the wear-resistant high polymer material is prepared from components in parts by weight as follows: 40-60 parts of an ABS (acrylonitrile-butadiene-styrene) material, 20-40 parts of glass fibers, 3-5 parts of a wear-resistant agent, 1-2 parts of a coupling agent, 1-2 parts of an antioxidant and 0.5-1.5 parts of a lubricant, wherein the lubricant is a mixture of calcium stearate, zinc stearate and octadecanamide, and a mass ratio of calcium stearate to zinc stearate to octadecanamide is 1:(1.1-1.5):1; (2), the raw materials of the wear-resistant high polymer material in the step (1) are subjected to dry blending in a high-speed mixer for 6-12 min, and a mixed raw material is obtained; (3), the mixed raw material obtained in the step (2) is added to a double-screw machine and subjected to melt extrusion and cooling granulation. The preparation method of the wear-resistant high polymer material has the advantages as follows: the quantity of auxiliaries in the formula can be reduced, and the high polymer material can be prevented from scaling precipitation.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a preparation method of wear-resistant polymer materials. Background technique [0002] ABS is a terpolymer of acrylonitrile, butadiene and styrene. It has good comprehensive properties, such as high impact strength, stable chemical properties, high heat resistance, flame retardancy, etc., so it is widely used in various machinery, Instruments and synthetic plastic materials. However, the surface hardness of ABS is relatively poor, and the product is easily scratched, which cannot satisfy long-term use. [0003] In response to the above phenomenon, patent CN105017707A discloses a wear-resistant material, which is made of the following raw materials in parts by weight: 35-75 parts of ABS material, 20-30 parts of glass fiber, 1-10 parts of wear-resistant agent, 1-5 parts of coupling agent, 0.5-1 part of antioxidant, 0.5-1 part of lubricant. In the present invention, th...

Problems solved by technology

The present invention has the advantages of superior comprehensive performance and wide application range, but there are still certain disadvantages: in the formula, when the lubricant is selected specifically, a single-component raw material additive or a two-component raw material additive is used, so the added amount Relatively many, and the polymer material will appear fouling and precipitation
