摘要:
为了提高苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)改性沥青的抗热氧老化及抗紫外线老化性能,以2,6-二叔丁基对甲酚(BHT)为原材料,利用BHT能够消除SBS改性沥青中自由基的作用机理,对掺加不同剂量BHT的SBS改性沥青进行旋转薄膜加热(RTOFT)延长老化试验、室内加速紫外线老化试验和常规路用性能试验.研究结果表明:BHT能够为SBS改性沥青中的自由基迅速提供氢原子,以提高沥青的抗氧化性能;BHT能够有效地提高SBS改性沥青的抗热氧老化及抗紫外线老化能力;BHT对SBS改性沥青的其他路用性能无明显提升或降低作用.
Abstract:
In order to improve the aging properties of styrene-butadiene-styrene(SBS)block copolymer modified asphalt, butylated hydroxytoluene(BHT)was used to be antioxidant, and some tests were conducted, such as: rolling thin film oven test(RTOFT)with long time, ultraviolet aging test, and usual road performance test with different BHT content. The test results show that BHT can provide H atoms to the free radical of SBS modified asphalt, the resistance to oxidation of SBS modified asphalt increases. BHT can also increase the anti-thermal oxygen aging, and anti-ultraviolet aging properties of SBS modified asphalt, but BHT does not obviously influence other properties.
