Direct vat set multifunctional asphalt mixture warm mixing agent and preparation method thereof
The invention discloses a direct vat set multifunctional asphalt mixture warm mixing agent and a preparation method thereof. The direct vat set multifunctional asphalt mixture warm mixing agent is prepared by stirring and mixing a component A, a component B and water at 50-60 DEG C. The component A is prepared by heating fatty acid and a catalyst to 90-100 DEG C, stirring, adding amine, and reacting for 3-4 hours under the action of vacuumizing. The component B is prepared by dissolving diisocyanate and a core material and then dropwise adding an emulsifier and water under the stirring action; and adding polyethylene glycol, continuously reacting for 1-1.5 hours, and drying in vacuum. The direct vat set multifunctional asphalt mixture warm mixing agent prepared by the invention can ensure the mixing workability of an asphalt mixture at a lower temperature and realize the warm mixing characteristic; the preparation method is simple, mild in condition, low in equipment requirement and suitable for large-scale industrial production; when in use, the mortar does not need to be premixed with asphalt, can be directly mixed with aggregate, and is simple and convenient.
本发明公开了一种直投式多功能沥青混合料温拌剂及其制备方法。所述的直投式多功能沥青混合料温拌剂由组分A、组分B和水在50‑60℃下搅拌混合即得。所述组分A是将脂肪酸和催化剂加热至90‑100℃，搅拌后再加入胺，抽真空作用下反应3‑4h即得。所述组分B是将二异氰酸酯和芯材溶解后在搅拌作用下滴加乳化剂和水；再加入聚乙二醇继续反应1‑1.5h，真空烘干即得。本发明制备的直投式多功能沥青混合料温拌剂，既可保证沥青混合料在较低温度时的拌和和易性，实现温拌特性；又可提升混合料性能，节约改性成本，且其制备方法简单，条件温和，对设备要求低，适合大规模工业化生产；使用时无需与沥青预拌，可直接与集料拌和，简单方便。
