The advantages and spirit of the present invention will be further understood from the following detailed description of the invention. [Embodiment] In general, the mechanism for suppressing combustion and extinguishing the flame is large. 201116549 has the following types: (1) physical dilution: increasing the amount of heat of the material by filling in an inert endothermic filler. Reduce the amount of combustibles in the material. For example, fiberglass, hollow glass spheres and talc fall into this category. (2) Chemical interaction: The formation of free radicals by means of thermal decomposition to capture highly reactive gas phase hydroxyl groups and hydrogen radicals results in a slower rate of thermal cracking chain reaction. For example, desertification flame retardants fall into this category. (3) inert gas dilution: due to the release of a large amount of water vapor and non-flammable gas during thermal decomposition, thereby diluting the flammable & body and oxygen content near the flame, and reducing the temperature of the place, resulting in combustion It has become more difficult. For example, metal hydroxides, nitrogen compounds and carbonates fall into this category. (4) Thermal quenching: The method of reducing the amount of heat released by the method of endothermic decomposition, which is used to reduce the temperature of the combustibles. For example, Lu, metal ruthenium oxides and carbonates belong to this category. (5) Protective coating: a non-combustible glassy fused layer or coke layer on the surface to isolate the transmission of oxygen and heat' and reduce the release of flammable gas, so that the degree of thermal cracking of the material reduce. For example, 1, the silicide is thermally decomposed to form a polyphosphoric acid and coke layer, and an intumescent flame retardant belongs to this category.
