Abstract

The invention relates to the field of high polymer materials and particularly relates to a highly-abrasion-resistant anti-scratching modified PC (polycarbonate) material and a preparation method thereof. The high-abrasion-resistant anti-scratching modified PC material comprises the following raw materials in parts by weight: 65-90 parts of PC, 10-35 parts of abrasion-resistant anti-scratching auxiliary agent, 0.5-1.5 parts of coupling agent, 1-10 parts of toughening agent, 0.1-1 part of antioxidant and 0.1-1 part of lubricating agent. According to the invention, PC is used as a substrate material, and composite systems such as the abrasion-resistant anti-scratching auxiliary agent, the lubricating agent, other auxiliary agents and the like are added, so that the abrasion-resistant anti-scratching property of the material is improved; the abrasion-resistant anti-scratching modified PC material is prepared by adopting high-temperature smelting, mixing and extruding modes in a twin-screw extruder, thus the hardness and abrasion-resistant anti-scratching effect of PC are improved; and modified PC has the advantages of high rigidity, high toughness, high flowability, high heat resistance, bright surface and the like.

Description

Technical field: [0001] The invention relates to the technical field of polymer materials, in particular to a highly wear-resistant and scratch-resistant modified PC material and a preparation method thereof. Background technique: [0002] PC (Polycarbonate, polycarbonate) material has excellent comprehensive mechanical properties and is widely used in mobile phones, computers and other electronic products. However, the disadvantage of PC material is that it has poor wear resistance and scratch resistance, especially for those with high requirements on appearance. Products, such as mobile phone casing structural parts, computer casing structural parts and other products that have high requirements for material wear resistance, general PC materials cannot meet the requirements for use. Usually, the method to improve the wear resistance of PC material products is to carry out surface coating , thus bringing the problems of complex manufacturing process and environmental pollut...
