Modified asphalt coating material, preparation method and waterproof coiled material
The invention provides a modified asphalt coating material, a preparation method and a waterproof coiled material. Wherein the modified asphalt coating material comprises the following raw material components in parts by weight: 100 parts of asphalt; 15 to 30 parts of a compatilizer; 8 to 15 parts of SBS elastomer; 35 to 50 parts of rubber powder; 50 to 80 parts of filler; and 6-12 parts of modified kaolin, wherein the modified kaolin is cooperatively modified by a sulfydryl silane coupling agent and an acyloxy titanate coupling agent. According to the invention, the sulfydryl silane coupling agent and the acyloxy titanate coupling agent are used for synergistically modifying the kaolin, so that the kaolin is changed from hydrophilicity to lipophilicity, and the dispersity of the kaolin in the asphalt is effectively improved; the modified kaolin can react with the SBS and the rubber powder, and the modified kaolin is used as a crosslinking point among the SBS, the rubber powder and the asphalt, so that chemical bonding of polymer-kaolin-asphalt is realized, the performance advantages of the components can be fully exerted, and the physical performance and the anti-aging performance of the polymer modified asphalt coating material are remarkably improved.
本申请提供一种改性沥青涂盖料、制备方法及防水卷材。其中，改性沥青涂盖料，包括下述重量份数的原料组分：沥青，100份；相容剂，15～30份；SBS弹性体，8～15份；胶粉，35～50份；填料，50～80份；改性高岭土6～12份，所述改性高岭土由巯基硅烷偶联剂和酰氧基钛酸酯偶联剂协同修饰。本申请采用巯基硅烷偶联剂和酰氧基钛酸酯偶联剂对协同对高岭土改性，使其由亲水性转变为亲油性，从而有效改善高岭土在沥青中的分散性；改性高岭土与SBS、胶粉可以发生反应，改性高岭土作为SBS、胶粉和沥青之间的交联点，实现了“聚合物‑高岭土‑沥青”的化学结合，可充分发挥各组分的性能优势，显著提高聚合物改性沥青涂盖料的物理性能与抗老化性能。
