Highly-abrasion-resistant anti-scratching modified PC (polycarbonate) material and preparation method thereof

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.
