Abstract

The invention discloses a glass fiber-reinforced recycled PC composite material, which is composed of: 13-85% of recycled PC material, 5-40% of chopped glass fiber, 3-15% of halogen-free phosphorus flame retardant, Halogen sulfonate flame retardant 0.1~0.6%, chain extender 0.1~2.0%, compatibilizer 0.5~4.0%, toughening agent 0.5~3.0%, processing aid 0.3~2.5%, antioxidant 0.1~ 0.6%, anti-dripping agent 0.2~1.0%, PC recycled material is at least one of low-soluble PC recycled, medium-soluble PC recycled and high-soluble PC recycled; the present invention uses different types of PC recycled As the base material, it is compounded according to different performance differences such as its melt index, and various PC recycled materials are reused, and the low molecular chains can be re-reacted and connected during the extrusion process through the chain extender to form a high The function of the molecular chain can improve or restore the mechanical properties of the material. The prepared PC composite material has excellent mechanical properties and flame retardancy. In addition, the present invention uses PC recycled materials instead of PC new materials to prepare PC composite materials, which can reduce costs. and environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic polymer materials, and in particular relates to a glass fiber reinforced recycled PC composite material and a preparation method thereof. Background technique [0002] The rapid development of the plastic industry has also brought negative effects on the environment. Statistics show that about 70-80% of the total plastic products will be converted into waste plastics within 10 years, and 50% of them will be converted into waste plastics within two years. Since these waste plastics are difficult to decompose and are scattered in nature for a long time, they will cause environmental pollution. Therefore, countries all over the world attach great importance to the recycling and reuse of waste plastics. [0003] At present, the processing methods of waste plastic packaging products mainly include: sanitary landfill, incineration and recycling. Landfilling and incineration of waste plastics have...
