Abstract

The invention provides wear-resisting PA / ASA alloy and a preparation method thereof. The wear-resisting PA / ASA alloy is prepared from the following ingredients in mass fraction: 40 to 60 parts of PA, 20 to 40 parts of ASA, 10 to 15 parts of compatilizer, 5 to 10 parts of reinforcement material and 0.5 to 1.5 parts of lubricant. The preparation method of the wear-resisting PA / ASA alloy comprises the steps of mixing all the ingredients of the formula amount and extruding the ingredients out through an extruding machine. The wear-resistant PA / ASA alloy provided by the invention has higher tensile strength, bending strength, toughness, wear resistance and heat resistance at the same time.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a wear-resistant PA / ASA alloy and a preparation method thereof. Background technique [0002] Polyamide (PA), commonly known as nylon, is a widely used engineering plastic with good mechanical strength, self-lubrication and good wear resistance. It is widely used in machinery, automobiles, electrical appliances, textile equipment, chemical industry Equipment, aviation, metallurgy and other fields. However, PA materials also have disadvantages such as high water absorption, poor dimensional stability, and low notched impact strength. [0003] Acrylonitrile-styrene-acrylate block copolymer (ASA), because the acrylate monomer containing single and double bonds is used to replace the butadiene monomer containing double and double bonds in ABS resin, so the ASA three after polymerization The element system does not contain double bonds, which greatly improves t...
