Abstract

The invention relates to the field of high polymer materials, in particular to a wear-resistant antibacterial degradable high polymer composite material. The composite material is prepared from the following raw materials in parts by weight: an ABS material, carbon fibers, ethylene pure fibers, polylactic acid, chitosan, plant fibers, tributyltin chloride, trichlorobenzeneurea, polyaniline, an ultra-high molecular weight wear-resistant agent, a coupling agent, a curing agent and a compatilizer. The high-molecular composite material has the advantages that the ABS material and the ultra-high molecular weight wear-resistant agent are added into the high-molecular composite material, so that the strength and hardness of the high-molecular composite material are obviously improved, the wear resistance is greatly improved, and meanwhile, the elasticity, toughness and antibacterial persistence of the material are improved by combining other raw material components; the application range of the polymer composite material is greatly widened, and the polymer material is mainly prepared from environment-friendly fiber material components, so that the degradability is greatly improved, and the environmental pollution rate is low.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a wear-resistant, antibacterial and degradable polymer composite material and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, the application of polymer materials is becoming more and more extensive. Many products that people come into contact with in daily life are made of polymer materials. Polymer material products have been closely related to life. Polymer materials have also become polymer materials. Composed of materials.
