Abstract

The invention provides a weather-resistant matte polycarbonate regenerated material and a preparation method thereof. The weather-resistant matte polycarbonate regenerated material includes the following raw materials in mass percentages: the first recycled crushed polycarbonate material: 3-15%, the second Two polycarbonate crushed materials: 60~83%, third polycarbonate recycled crushed materials: 3~10%, fogging agent: 10~25%, antioxidant: 0.2~1.0%, light stabilizer: 0 ~0.6%, UV absorber: 0.1~1.0%. The invention improves the weather resistance of polycarbonate and its processing performance through the addition of fogging agent, antioxidant, light stabilizer and ultraviolet absorber, and obtains a modified material with relatively stable melt index. Not much different from 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 a kind of 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 produce a lot of waste materials. At present, there are two main ways to process it. recycle and re-use: [0003] 1. The method of incineration or landfill, but harmful gas will be produced during the incineration process, causing serious environmental pollution; and the method of landfill will cause great harm to the environment due to its refractory degradation, and at the same time cause soil pollution. waste. [0004] 2. Simple recycling of waste materials without scientific modification, downgrading...
