Self-healing modified asphalt as well as preparation method and application thereof
The invention discloses self-healing modified asphalt as well as a preparation method and application thereof. The self-healing modified asphalt is prepared from the following raw materials in percentage by weight: more than or equal to 30% of liquid rubber, with the balance being matrix asphalt, wherein the liquid rubber is obtained by adding tire rubber powder and a certain amount of a metal ioncatalyst into a reaction type screw extruder, pumping air into the reaction type screw extruder and then performing extruding. The self-healing modified asphalt is a mixture prepared by firstly adding liquid rubber into matrix asphalt and then conducting uniform blending. The self-healing modified asphalt provided by the invention not only has the advantages of outstanding ageing-resistant self-healing capability, environment-friendly processing process and the like, but also has both high-temperature and low-temperature performance and a wide range of applicable temperature; the preparationmethod is novel, efficient and convenient; and the self-healing modified asphalt is suitable for being widely applied to asphalt road construction and asphalt-based waterproof coiled material products, and has strong practicability and remarkable economic benefits.
本发明公开了一种自愈合改性沥青及其制备方法和用途，所述自愈合改性沥青的原料包含以下组分及重量百分比含量：液体橡胶≥30%，其余为基质沥青；所述液体橡胶为先将轮胎胶粉与一定量的金属离子催化剂加入到反应型螺杆挤出机中，同时往反应型螺杆挤出机中泵入空气，然后挤出得到；所述自愈合改性沥青为先将液体橡胶加入到基质沥青中，然后共混均匀而制得的混合物。本发明产品不但具有突出的耐老化自愈合能力、加工过程环保等优点，而且高低温性能兼顾、温度适应范围广，制备方法新型、高效、方便，适合大量应用于沥青道路建设和沥青基防水卷材产品，实用性强，经济效益显著。
