Abstract

The invention provides a polycarbonate material as well as a preparation method and application thereof. The polycarbonate material is prepared from the following components in parts by weight: 80 to99 parts of polycarbonate and 0.1 to 15 parts of a modified nano oxide. Wherein the modified nano oxide is modified by a coupling agent, a hyperbranched polyester and a rare earth ion together; the modified nano oxide has good dispersibility in a polycarbonate matrix material, not only can the scratch resistance and tensile strength of the polycarbonate material be improved, but also the influenceof the modified nano oxide on the impact toughness, blackness and surface gloss of the obtained material is small through a reasonable proportion and a scientific preparation method. The polycarbonate material provided by the invention is relatively good in scratch resistance, high in gloss retention rate, relatively good in tensile strength, and relatively excellent in physical properties such as surface gloss, blackness and impact toughness.

Description

Technical field [0001] The invention belongs to the field of polymer materials, and specifically relates to a polycarbonate material and a preparation method and application thereof, and in particular to a high-gloss black scratch-resistant PC material, and a preparation method and application thereof. Background technique [0002] Polycarbonate (PC) is an aromatic polymer containing carbonate groups in the molecular chain. It is an excellent engineering plastic with good comprehensive properties, high mechanical strength, good impact resistance, dimensional stability, and light transmission. With good heat resistance and electrical insulation, it is widely used in machinery, automobiles, electrical appliances and other industries. [0003] However, when applied to the interior and exterior of automobiles (such as dashboard decoration panels, heat dissipation grilles, etc.), communication equipment (such as smart phone casings, wireless network card casings, etc.), secondary proces...
