Abstract

The invention relates to a preparation method of a wear-resistant high polymer material. The preparation method comprises the steps as follows: (1) the wear-resistant high polymer material is prepared from components in parts by weight as follows: 30-70 parts of an ABS (acrylonitrile butadiene styrene) material, 20-40 parts of glass fiber, 2-6 parts of a wear-resistant agent, 1-3 parts of a coupling agent, 1-2 parts of an antioxidant and 1-2 parts of a lubricant, wherein the coupling agent is a mixture of a coupling agent KH550 and a coupling agent KH560 in the mass ratio being (2.1-2.7):1; (2) the raw materials of the wear-resistant high polymer material in the step (1) are subjected to dry mixing in a high-speed mixer for 6-12 min, and a mixed material is obtained; (3) the mixed material obtained in the step (2) is added to a twin-screw extruder for melt extrusion, and cooling and granulation are performed. The preparation method has the advantages as follows: the dosage of aids in the formula can be reduced and the dispersing performance of the high polymer material can be improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates 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 i...
