Problems solved by technology

Plastics are widely used due to their light weight and low cost, but they are limited by the molecular structure of the plastic’s own flexible long-chain polymers. Plastic parts have low surface hardness, low bulk phase stiffness, and poor dimensional stability. Poor, so that when applied to the motion mechanism, it is prone to inflexible rotation, stuck, high-cycle rotation, high temperature and rubbing and chipping problems

Abstract

The invention provides a moving part, a wear-resistant ABS (Acrylonitrile Butadiene Styrene) material and a preparation method thereof. The wear-resistant ABS material is prepared from the following components in parts by weight: 35 to 45 parts of modified butadiene-styrene rubber, 45 to 65 parts of ABS matrix resin, 1 to 2.5 parts of antioxidant and 1 to 5 parts of polytetrafluoroethylene, wherein the modified butadiene-styrene rubber is prepared from the following components in parts by weight: 60 to 70 parts of butadiene-styrene, 10 to 20 parts of organic silicon microspheres and 10 to 20 parts of glass fibers. A workpiece prepared from the wear-resistant ABS material is flexible and smooth during high-speed rotation, is free of the problems of overheating and friction chip falling, and is relatively good in wear resistance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a moving part, a wear-resistant ABS material and a preparation method thereof. Background technique [0002] With the rapid development of the home appliance industry, consumers are no longer satisfied with a single fixed model of products, but are chasing dynamic comfort or technological experience, such as rotating or lifting products according to scene changes and experience needs. exercise requirements. Plastics are widely used due to their light weight and low cost, but they are limited by the molecular structure of the plastic’s own flexible long-chain polymers. Plastic parts have low surface hardness, low bulk phase stiffness, and poor dimensional stability. Poor, when applied to the motion mechanism, it is prone to inflexible rotation, stuck, high-period rotation, high temperature and rubbing and chipping problems. Contents of the invention [0003] The ob...
