Composite modified red mud-based asphalt anti-aging agent, and preparation method and application thereof
The invention relates to a composite modified red mud-based asphalt anti-aging agent which comprises 40-70 parts of red mud, 1-3 parts of a nano material, 10-30 parts of a red mud modified material, 1-2 parts of a chemical solvent and 10-20 parts of aromatic oil, furthermore, the chemical solvent is a coupling agent, preferably, one or a mixture of several of a silane coupling agent, a titanate coupling agent and an aluminate coupling agent. Furthermore, the red mud modified material is a mixture of one or more of slaked lime, montmorillonite and cement. The coupling agent is used for carrying out composite modification on the red mud, the comprehensive performance of the modified red mud can be effectively improved, the modified red mud can play a role in blocking ultraviolet rays and oxygen, and the purpose of resisting aging of the asphalt mixture is achieved.
本发明涉及一种复合改性赤泥基沥青抗老化剂，包括：赤泥40‑70份，纳米材料1‑3份，赤泥改性材料10‑30份，化学溶剂1‑2份，芳烃油10‑20份；进一步地，所述化学溶剂为偶联剂，优选的，选自硅烷偶联剂、钛酸酯偶联剂、铝酸酯偶联剂中的一种或几种的混合物。进一步地，所述赤泥改性材料为消石灰、蒙脱土、水泥中的一种或多种的混合物。本发明通过使用偶联剂对赤泥进行复合改性，可以有效地提高改性赤泥的综合性能，改性后的赤泥能够起到阻隔紫外线和氧气的作用，达到沥青混合料抗老化的目的。
