| Abstract: | The styrene - butadiene - styrene block copolymer （SBS） modified halogen -free flame retardant asphalt was prepared with asphalt Liaohe AH- 90 as matrix, SBS as modifier, mixture of ammonium polyphosphate, pentaerythritol, polydimethylsiloxane,Mg（OH）2 ,AI（OH）3 in the mass ratio of 2 ： 3 ： 2 ： 1 ： 1 as composite flame retardant, and LKJ- II as blending agent. The performance evaluation results showed that the main physico - chemical properties of SBS modified halogen - free flame retardant asphalt could meet the need of the Standard JTG F 40--2004. When the mass fraction of the composite flame retardant in the matrix was 15% ,the oxygen index was 31.5% ,the smoke density was 37.44, and the smoke toxicity was up to grade ZA 1. |
