Asphalt anti-stripping agent as well as preparation method and application thereof

The invention discloses an asphalt anti-stripping agent as well as a preparation method and application thereof. The asphalt anti-stripping agent comprises the following raw materials: butadiene styrene rubber, triphenylmethane triisocyanate, a p-phenylenediamine compound and a coupling agent. The preparation method of the asphalt anti-stripping agent comprises the following steps: uniformly mixing the materials, mixing and granulating to obtain the asphalt anti-stripping agent. The asphalt anti-stripping agent disclosed by the invention is granular, is used in airport asphalt, can remarkably improve the adhesion strength of the asphalt and improve the anti-stripping performance, and has relatively strong adaptive capacity to a high-temperature wake flow environment of an airplane. 本发明公开了一种沥青抗剥离剂及其制备方法和应用。该沥青抗剥离剂包括如下原料：丁苯橡胶、三苯基甲烷三异氰酸酯、对苯二胺类化合物、偶联剂。该沥青抗剥离剂制备方法包括：将上述物料混合均匀，经混炼，造粒，得到沥青抗剥离剂。本发明的沥青抗剥离剂呈颗粒状，用于机场沥青中，能够显著提高沥青的黏附强度，改善抗剥离性能，对于飞机高温尾流环境具有较强的适应能力。
