Preparation system and process of solid epoxy modified asphalt for roads and bridges
The invention relates to the technical field of asphalt mixture production, in particular to a system and a process for preparing solid epoxy modified asphalt for roads and bridges, the system comprises a stock bin, a resin heating device, a static mixing container, an asphalt storage tank, a mixture mixing cylinder, a first feeding mechanism and a metering feeding mechanism, according to the device, the solid epoxy component A and the solid epoxy component B are mixed, melted and heated into the epoxy melt, one part of the epoxy melt is mixed with the aggregate, so that the surface of the aggregate is firmly coated with a layer of solid epoxy melt, and the other part of the epoxy melt is mixed with the active asphalt to form the solid epoxy modified asphalt with good stability; according to the solid epoxy modified asphalt mixture disclosed by the invention, the-COOH group in the active asphalt and the epoxy group in the solid epoxy melt coated on the surface of the aggregate are subjected to chemical reaction to form firm chemical bond connection, and finally a firm structure of the aggregate, the solid epoxy melt and the solid epoxy modified asphalt is formed from inside to outside, so that the quality of the solid epoxy modified asphalt mixture is improved.
本发明涉及沥青混合料生产技术领域，尤其涉及一种路桥用固体环氧改性沥青制备系统及工艺，该系统包括：料仓、树脂加热装置、静态混合容器、沥青储存罐、混合料拌合缸、第一上料机构和计量上料机构，本发明通过上述装置来将固体环氧A组分和固体环氧B组分混合后熔融加热成环氧熔体，并将环氧熔体一部分与集料混合，使集料表面牢固地裹附一层固体环氧熔体，另一部分与活性沥青混合形成稳定性良好的固体环氧改性沥青，活性沥青中的‑COOH基团与集料表面裹附的固体环氧熔体中的环氧基团发生化学反应，形成牢固的化学键连接，最终由内到外形成集料、固体环氧熔体，固体环氧改性沥青的牢固结构，有助于提升固体环氧改性沥青混合料的品质。
