Abstract

The invention discloses a photodegradation rate-controllable polycarbonate material and a preparation method thereof. In the preparation method, the photodegradation rate-controllable polycarbonate material can be obtained by fusing and mixing a polycarbonate (PC) master batch and a composite catalyst of nano-titanium dioxide and nitrogen or nano-titanium dioxide and nitrogen, lanthanum, cerium, praseodymium or neodymium in a mass ratio of (94-98):(2-6). The problems of the nondegradation and the degradation rate of polycarbonate in a natural light state are solved. After adding a photocatalyst, no adverse effect is generated to the processing performance and the using performance of a product. After being abandoned, the polycarbonate brings very high environmental load because of low cost, large market usage amount and nondegradation.

Description

technical field [0001] The invention relates to a formula of polycarbonate, in particular to a polycarbonate material with controllable photodegradation speed and a preparation method thereof. Background technique [0002] Due to its excellent properties, plastics have been widely used, but the environmental pressure brought about by its stability continues to increase, and the problems caused by the post-processing of plastics are particularly difficult. Although methods such as landfilling, burning and recycling can be adopted, the research results have proved that these methods have disadvantages to varying degrees. Due to its excellent properties, polycarbonate has been widely used in various fields, but polycarbonate is not biodegradable, and the environmental load brought by disposal is one of the problems faced by human beings. Contents of the invention [0003] The object of the present invention is to solve the above existing problems in the prior art, and provid...
