In recent decades, with the continuous progress of science and technology in China, asphalt, as a basic building raw material, its application technology and application fields are also developing. But the inherent flammability of asphalt makes it easy to ignite at high temperatures, accompanied by a lot of smoke and heat, which is extremely dangerous. Therefore, it is necessary to use asphalt flame retardants. So,asphalt flame retardantwhat is the role?

　　asphalt flame retardantAt high temperatures, a strong endothermic reaction will be generated, and some heat will be absorbed from the combustion, thereby reducing the surface temperature of the combustible material, inhibiting the formation of combustible gas, and ultimately achieving the purpose of flame retardant and preventing the spread of combustion. Under high temperature conditions, the asphalt flame retardant can form a stable foam coating or glass shape, isolated from the air, to achieve the purpose of oxygen insulation, to prevent the leakage of combustible gas, play a flame retardant effect.

When the asphalt flame retardant is heated, it will decompose CO2.CI.NH2.HBR and other gases. These gases can effectively dilute the combustible gas that is combustible and decomposed, and reduce the concentration of combustible gas below combustion. At the same time, it can effectively dilute the oxygen concentration in the combustion area to prevent the combustion from continuing, so as to achieve the purpose of flame retardant.

This is its relevant operation in terms of flame retardancy. And in accordance with the related combustion chain reaction problem, to maintain the free radicals needed for combustion. introduction of halogenasphalt flame retardantIt can effectively capture the free radicals in the combustion reaction and act on the gas phase combustion zone. It reduces the flame density in the combustion zone, prevents the spread of the flame, and finally reduces the combustion reaction speed until the end of the combustion, thus achieving the purpose of flame retardant.
