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

Abstract

The invention discloses an environment-friendly polyethylene flame-retardant plastic which is prepared from the following raw materials in parts by weight: 60-68 parts of polyethylene, 20-23 parts of EVA (ethylene-vinyl acetate), 5-9 parts of amino-terminated polyol ester, 3-7 parts of red phosphorus, 5-8 parts of diisononyl phthalate, 4-6 parts of organic montmorillonite, 4-8 parts of dibutyl sebacate, 6-8 parts of triphenyl phosphate, 7-10 parts of zinc borate, 4-8 parts of nano silicon dioxide, 4-7 parts of zinc borate hydrate, 4-7 parts of heat stabilizer and 6-8 parts of coupling agent. The product is free of halogen, and has favorable flame-retardant function; the heat-deformation temperature, mechanical temperature, electric insulation property and other properties of the prepared product are not influenced; and the plastic has long-term flame retardancy, is environment-friendly and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an environment-friendly polyethylene 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 i...
