Abstract
The invention discloses modified plastic with an abrasion-resistant surface. The modified plastic comprises the following raw materials in parts by mass: 80-100 parts of polycarbonate, 10-15 parts of whisker silicon, 5-10 parts of polytetrafluoroethylene micro powder, 5-10 parts of silicone powder, 3-8 parts of a scratch-resistant agent, 5-15 parts of nano-graphite, 3-5 parts of a silane coupling agent, 3-5 parts of a dispersing agent and 5-10 parts of an enhance mixing agent. According to the modified plastic, polycarbonate is subjected to filling modification, so that the scratch resistance of polycarbonate is greatly improved, and the surface abrasion resistance is improved; the modified plastic is good in thermal property and mechanical property, environment-friendly and free of pollution.
Description
Technical field
The present invention relates to modifying plastics field, particularly relate to a kind of surface abrasion resistance modified plastics.
Background technology
Polycarbonate (PC) is the thermoplastic engineering plastic of excellent combination property.Its odorless, tasteless, nontoxic, firm and have toughness, having outstanding impact resistance and dimensional stability, and have higher thermotolerance and winter hardiness, is the product uniquely in five large-engineering plastics with the transparency, and being described as is transparent metal.Product is widely used in electric, automobile, machinofacture, aerospace, the technical field such as computer and CD.But, the surface scratch resistance of PC material can be very poor, reduce the aesthetic measure of product to a great extent, and also can cause stress concentration at the cut that product surface produces, so the shell to electronic products such as the high field such as mobile phones of product surface performance requriements, the application of PC is subject to a definite limitation.In order to expand the application of PC in high-end product, need to carry out surface abrasion resistance modification to it.
