Problems solved by technology

[0003] When plastic products are exposed to fire, they generate a large amount of heat, burn quickly, produce a large amount of melting entropy, and are accompanied by smoke. With the improvement of environmental protection and the enhancement of environmental awareness, the requirements for the flame retardancy of plastics are getting higher and higher, and ordinary flame retardants can no longer meet people's requirements.

Abstract

The invention relates to the technical field of fire retardant invention and development, and discloses a phosphorus-based flame retardant applied to a plastic product. The phosphorus-based flame retardant is prepared from the following ingredients in parts by weight: 80 to 90 parts of diethyl phosphite, 70 to 75 parts of epoxy silicon resin, 18 to 22 parts of ethylenediamine tetracetic acid, 10 to 15 parts of triethylamine, 4 to 6 parts of hexamethyldisiloxane and 10 to 15 parts of distilled water. The compound flame retardant comprises silicon resin, so that the system flame retardant performance is improved; the thermal stability of the surface carbon layer is increased through the Si-O-Si reticular structure formed after the decomposition. When the prepared phosphorus-based flame retardant provided by the invention is applied to the plastic product, the combustion grade can reach FV-O stage only through the very low addition; each flame retardant performance index of the plastic product can be improved; the mechanical properties of the plastics, including the break elongation and the anti-impact performance can also be improved.

Description

technical field [0001] The invention belongs to the technical field of research and development of flame retardants, and in particular relates to a phosphorus-based flame retardant used in plastic products. Background technique [0002] With the development of modern science and technology, polymer materials are more and more widely used in various fields. However, these materials are generally flammable or combustible, and fire accidents caused by this have become a social issue that people generally care about. Due to the increasing demand for flame retardant and fire prevention worldwide and the improvement of flame retardant regulations, the research, development and production application of flame retardant chemicals have been directly promoted. In order to solve the problems of flame resistance, smoke suppression and low toxicity of synthetic materials and ensure the safety of synthetic materials, the most effective way is to add a highly efficient and non-toxic flame...
