Acid aggregate bio-based asphalt anti-stripping agent and preparation method thereof
The invention relates to the technical field of pavement asphalt, in particular to an acidic aggregate bio-based asphalt anti-stripping agent and a preparation method thereof. The acidic aggregate bio-based asphalt anti-stripping agent comprises 68-72 parts of plant asphalt, 10-14 parts of polybutadiene glycol, 0.05 part of a catalyst, 3-5 parts of vital gluten, 2-4 parts of furfural, 3-5 parts of polyvinyl imine, 3-5 parts of triethanolamine and 2.95 parts of an auxiliary agent. According to the acid aggregate bio-based asphalt anti-stripping agent provided by the invention, the plant asphalt is selected as a main raw material, and is natural, environment-friendly and wide in source; and the wheat gluten and triethanolamine react to form a three-dimensional network structure, and the three-dimensional network structure has good viscoelasticity, extensibility, thermal coagulability, emulsibility and film formability. Furfural reacts with polyvinyl imine to form a coronal structure with strong complexing ability, and the coronal structure and the acidic aggregate are strongly complexed, so that the adhesive property is improved; and meanwhile, the asphalt anti-stripping agent can also reduce the interface energy between the asphalt and the aggregate to form a stable system.
本发明涉及路面沥青技术领域，具体涉及一种酸性集料生物基沥青抗剥离剂及其制备方法，植物沥青68‑72份、聚丁二烯二醇10‑14份、催化剂0.05份、谷朊粉3‑5份、糠醛2‑4份、聚乙烯基亚胺3‑5份、三乙醇胺3‑5份以及助剂2.95份。本发明中提供了一种酸性集料生物基沥青抗剥离剂，其中主要原料选取植物沥青，天然环保且来源广泛；谷朊粉与三乙醇胺反应形成三维网状结构，具有良好的粘弹性、延伸性、热凝固性、乳化性以及薄膜成型性。糠醛与聚乙烯基亚胺反应形成络合能力强的冠状结构，与酸性集料之间发生强力络合，提高粘结性能；同时本发明中沥青抗剥离剂还可以降低沥青与集料之间的界面能，形成稳定体系。
