Asphalt flame retardant and preparation method and application thereof
The invention relates to the technical field of flame-retardant asphalt and particularly provides an asphalt flame retardant. The asphalt flame retardant is prepared from, by weight, 40%-60% of epoxy resin coated ammonium polyphosphate, 10%-20% of inorganic flame retardant, 10%-20% of zinc borate, 10%-20% of diatomite, 2%-4% of surface modification agent and 1%-3% of antioxidant. The invention further provides a preparation method and application of the asphalt flame retardant. The asphalt flame retardant has higher flame-retardant efficiency, enables the limit oxygen index of asphalt to be increased to be above 24, can prevent flame combustion, can also inhibit smoldering, has good compatibility with asphalt, can be evenly dispersed in an asphalt mixture, has better affinity, meanwhile does not affect various technical indexes of the asphalt mixture, does not produce poisonous gas, is safe, is environmentally friendly and is simple in production process, lower in cost and stable in quality.
