Abstract

The present invention relates to a phosphazene compound, a composition comprising the phosphazene compound, a flame retardant comprising same, and the use thereof. The crystal form of a cyclotriphosphazene derivative flame retardant synthesized according to the present invention is the most stable crystal form, and same has a good heat stability and a high flame retardant efficiency; moreover, materials, whether engineering plastics or general-purpose plastics, as well as lithium ion battery electrolyte solutions, flame retardant fabrics and flame retardant papers, to which the crystal type cyclotriphosphazene derivative flame retardant synthesized according to the present invention has been added, are provided with an excellent flame retardant performance, a stable crystal form, and drip resistance, and only an extremely small addition amount is required to allow the flame retardant performance of a material to achieve V-0 standards, while the impact on the other properties of the material is relatively small.

Description

technical field [0001] The invention relates to the field of chemical industry, more specifically, to a compound applicable to a flame retardant, a composition containing the compound and a production method thereof. The invention also provides the application of the compound and the composition containing the compound in flame retardancy in various industrial productions. Background technique [0002] my country is a big producer and user of organic materials. The fires caused by the burning of organic materials cause serious personal and property losses every year, and most organic materials tend to release a large amount of toxic gases when heated or burned, so they are not suitable for food packaging that has been heated repeatedly. It is not conducive to the escape of personnel at the scene of a fire accident caused by the burning of organic materials. For a long time, both at home and abroad have attached great importance to the research and product development of envi...
