Problems solved by technology

In recent years, many manufacturers at home and abroad have begun to research and develop flame-retardant plastics. However, most of the flame retardants added at present are halogen-based flame retardants, which will produce toxic hydrogen halides during long-term use, especially during combustion. Substances can cause great harm to people's health and the environment

The plastic has long-term flame retardancy and is environmentally friendly. mass production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an environment-friendly PC flame-retardant plastic. technical background [0002] At present, plastic products are more and more widely used in many fields because of their unique good electrical resistance properties and high-frequency insulation properties that are not affected by humidity. However, since plastic itself is not flame retardant, it can cause fires due to its flammability when used in the electronics, construction, aviation and automotive industries. At present, with the advancement of technology, ubiquitous new products and new things have brought convenience and fast services to people's life and work, and people's lives have undergone earth-shaking changes. In order to protect national public property and citizens' personal safety, and to eliminate fire hazards, "high-quality and safe life" will gradually become an indispensable factor in life whil...
