Abstract

The invention provides a weather-resistant matt polycarbonate regenerated material and a preparation method thereof. The weather-resistant matt polycarbonate regenerated material is prepared from thefollowing raw materials in percentage by mass: 3 to 15 percent of first polycarbonate recycled crushed materials, 60 to 83 percent of polycarbonate recycled crushed materials, 3 to 10 percent of thirdpolycarbonate recycled crushed materials, 10 to 25 percent of matte surface agents, 0.2 to 1.0 percent of antioxidants, 0 to 0.6 percent of light stabilizing agents and 0.1 to 1.0 percent of ultraviolet absorbents. Through the addition of the matte surface agents, the antioxidants, the light stabilizing agents and the ultraviolet absorbents, the weather resistant performance of polycarbonate is improved; the processing performance is improved; the modified material with stable melt index is obtained; the performance is similar to that of a new material.

Description

technical field [0001] The invention relates to the technical field of polycarbonate recycling, in particular to a weather-resistant matte polycarbonate recycled material and a preparation method thereof. Background technique [0002] Polycarbonate is an engineering plastic with excellent comprehensive performance and wide application. It is widely used in electrical and electronic, automobile, machinery and other industries. Because of its wide application, it will generate a lot of waste materials. At present, there are mainly two ways to deal with it. recycle and re-use: [0003] 1. The method of incineration or landfill, but in the process of incineration, harmful gas will be generated, causing serious environmental pollution; while the method of landfill will cause great harm to the environment due to its refractory degradation, and at the same time cause soil waste. [0004] 2. Simple recycling of waste materials without scientific modification, downgrading them to o...
