High-viscosity asphalt modifier, preparation method thereof, modified asphalt and asphalt mixture
The invention discloses a high-viscosity asphalt modifier and a preparation method thereof, modified asphalt and an asphalt mixture. The raw materials of the high-viscosity asphalt modifier comprise the following components in percentage by mass: 50-70% of modified thermoplastic elastomer which is carboxylated SBS (Styrene Butadiene Styrene), and the functionality of the carboxylated SBS is 8-14 mol%; 10%-50% of a compatibilizer, wherein the compatibilizer is one or more of vegetable oil, animal oil and rubber operating oil; 15% to 50% of tackifying resin; 1%-5% of an anti-stripping agent; 1%-5% of a leakage analysis inhibitor; the percentage is the mass percentage of each component in the high-viscosity asphalt modifier, and the sum of the mass percentage of each component is 100%. The high-viscosity asphalt modifier disclosed by the invention is relatively good in dispersity in asphalt, and meanwhile, the high-temperature stability, the water stability, the low-temperature cracking resistance, the aging resistance and the like of the modified asphalt can be improved.
本发明公开了一种高粘度沥青改性剂及其制备方法、改性沥青和沥青混合料。该高粘度沥青改性剂的原料包括下列质量分数的组分：50％～70％的改性热塑性弹性体，改性热塑性弹性体为羧基化SBS，羧基化SBS的官能度为8～14mol％；10％～50％的增容剂，增容剂为植物油、动物油和橡胶操作油中的一种或多种；15％～50％的增粘树脂；1％～5％的抗剥落剂；1％～5％的析漏抑制剂；百分比为各组分占高粘度沥青改性剂的质量百分比，各组分质量百分比之和为100％。本发明中的高粘度沥青改性剂在沥青中分散性较好，同时能提高改性沥青的高温稳定性、水稳定性、低温抗开裂性、抗老化性等性能。
