Description

technical field [0001] The invention belongs to the field of flame retardants, and relates to a polymeric flame retardant and its preparation method and application. Background technique [0002] Traditional flame retardant technology is generally divided into halogen flame retardant and halogen-free flame retardant. [0003] In the prior art, the way of halogen flame retardant is generally to react molecules containing halogen and reactive groups with other materials to make halogen flame retardant materials, or to use non-reactive groups such as decabromodiphenylethane High-quality halogen flame retardants are directly added to the material to achieve the purpose of flame retardancy. At the same time, in order to improve the flame retardant effect, it is often necessary to add antimony trioxide and other combustion aids that are harmful to organisms and unfriendly to the environment in the flame retardant system. When halogen-containing flame retardant substances are dec...
