一种高渗透性SBR-纳米材料复合改性乳化沥青及其制备方法
摘要：
本发明公开了一种高渗透性SBR-纳米材料复合改性乳化沥青，由以下质量百分数的原料制成：基质沥青45~55%、粉末丁苯橡胶1~3%、纳米二氧化钛0.3~2%、石墨烯0.5~1.5%、纳米二氧化铈0.3~2%、乳化剂2~4%、有机稳定剂0.4~0.6%、无机稳定剂0.4~0.6%、羧基丁苯胶乳2~3%，余量为水；本发明还公开了该SBR-纳米材料复合改性乳化沥青的制备方法。本发明制备工艺简单、易于控制，且制得的SBR-纳米材料复合改性乳化沥青均匀、稳定，具有极强的渗透能力和力学性能，可大幅提高其作为桥面铺装或半刚性基层沥青路面粘结层的性能。
摘要（英）：

The invention discloses high-permeability SBR-nanomaterial composite modified emulsified asphalt. The high-permeability SBR-nanomaterial composite modified emulsified asphalt is prepared from the following raw materials in percent by mass: 45-55% of matrix asphalt, 1-3% of powdered styrene-butadiene rubber, 0.3-2% of nanometer titanium dioxide, 0.5-1.5% of graphene, 0.3-2% of nanometer cerium dioxide, 2-4% of an emulsifying agent, 0.4-0.6% of an organic stabilizer, 0.4-0.6% of an inorganic stabilizer, 2-3% of carboxylic styrene-butadiene latex and the balance of water. The invention further discloses a preparation method of the SBR-nanomaterial composite modified emulsified asphalt. A preparation technology is simple and easy to control; the prepared SBR-nanomaterial composite modified emulsified asphalt is uniform and stable and has very strong permeability and mechanical properties, and the performance of the high-permeability SBR-nanomaterial composite modified emulsified asphalt asa bonding layer of a bridge deck pavement or semi-rigid base asphalt pavement can be greatly improved.
