In general, the Flame Retardant mechanisms of bromine and chlorine systems are similar. At high temperature, the carbon-halogen bond in halogen-based flame retardants will be damaged, releasing halogen free radicals, which can effectively capture free active free radicals generated by thermal degradation of polymer materials, and can effectively reduce the concentration of free radicals, thereby alleviating or stopping burning free radical chain reaction.
In addition, because the released hydrogen halide is not easy to burn, halogen-based flame retardants can effectively block oxygen and suppress the burning reaction. However, when a polymer material containing a halogen flame retardant is incinerated, a large amount of hydrogen halide gas is generated. This gas is toxic and corrosive. At the same time, it also simply absorbs moisture in the air, forming a highly corrosive hydrogen halide acid, along with a lot of smoke.
These fumes, toxic gases and corrosive gases will damage human health and bring great obstacles to life-saving, escape and recovery. Flame retardant manufacturers: treated aluminum hydroxide flame retardant aluminum hydroxide, also known as trihydrate oxidation Aluminum (ATH), with the molecular formula Al(OH)3, is one of the earliest inorganic flame retardants - it can act synergistically with a variety of substances.
The effect is the same, and it is non-toxic and non-corrosive. The above is the introduction of the reaction mechanism of common flame retardants. The flame retardant effect of inorganic flame retardants is mainly due to the heat storage and thermal conductivity of large specific volume fillers, which makes it difficult for materials to reach the decomposition temperature. heat, thereby easing or terminating the heating process of the host material. Its flame retardant mechanism is to release crystal water when heated, and to release water vapor by transpiration.
