Description

technical field [0001] The invention belongs to the technical field of flame retardants, and in particular relates to a preparation method and application of a silicone-modified high-temperature resistant flame retardant. Background technique [0002] Flame retardant is a functional additive that can make flammable polymers flame retardant. It is mainly designed for the flame retardant of polymer materials. There are many types of flame retardants, which are divided into additive flame retardants according to the method of use. agent and reactive flame retardant. Additive flame retardants are added to polymers by mechanical mixing to make polymers flame retardant. At present, additive flame retardants mainly include organic flame retardants and inorganic flame retardants, halogenated flame retardants and non-halogenated flame retardants. flame retardant. Organic flame retardants are some flame retardants represented by bromine, phosphorus nitrogen, red phosphorus and the...
