Fire caused by traffic accidents is a problem that must be considered during the use of asphalt pavement in tunnels. The combustion of asphalt combustion gases released further accelerate the thermal decomposition of asphalt, in addition to the tunnel in the confined environment of a large number of smoke and harmful gases on the person and the environment has also caused great harm. To solve the problem of asphalt refractory to combustion, first of all, to solve the asphalt when heated, not soluble droplets, not flow, improve the melting point and decomposition temperature of asphalt, increase the decomposition of gases in the non-combustible components or increase the inhibition of the combustion film components, in order to improve the combustion of the oxygen index of the purpose of the flame retardant to provide an effective solution.

The recommended dosage is about 5% of the asphalt dosage.
Can be added directly to the hot melt asphalt, to ensure that the mixing more than 20 minutes.
It can be directly added into the colloid mill of asphalt modification equipment with high speed shear mixing emulsifier, shear for 20 minutes to make fire retardant modified asphalt, and then introduced into the storage tank with stirring, constant temperature to 175-180 °C.

Absorb a large amount of heat, blocking the heat transfer chain and reducing the surface temperature of combustible materials.
Eliminate the highly active free radicals (HO and H) produced in the early stage of oxidation, inhibiting the chain reaction.
Heat released a large number of non-combustible gases covered in the asphalt surface, cut off heat, combustible gases, oxygen to the asphalt transfer, and dilute the content of combustible gases.
In the asphalt surface to form a coked non-combustible carbonized layer, isolate the oxygen and combustible contact, and terminate the combustion, resulting in self-extinguishing, to achieve the purpose of flame retardant, and smoke suppression.

Our production of asphalt flame retardant using a variety of flame retardants and smoke suppressant synergistic, to solve the asphalt flame retardant in less asphalt flame retardant additives to achieve the purpose of asphalt flame retardant to ensure that the asphalt of the road performance is not affected by the larger.

Protect from moisture, exposure, and hooking.
If the flame retardant modifier into the eyes, flush with fresh water, and immediately seek medical treatment.
In order to prevent a small amount of segregation of asphalt after adding fire retardant in long-term storage affects the performance of asphalt and fire retardant effect, the storage tank is required to have mixing equipment.
Shelf life is 18 months under normal storage conditions.
