Asphalt concrete anti-stripping agent and preparation method thereof
The invention provides an asphalt concrete anti-stripping agent and a preparation method thereof. The anti-stripping agent comprises the following raw materials: rosin, organic anhydride, polyethylene glycol and potassium hydroxide. The preparation method comprises the following steps: successively adding rosin and organic anhydride into a reaction kettle for condensation reaction, then adding polyethylene glycol for esterification reaction, adding alkali for saponification reaction, cooling the product, and crushing into particles to obtain the asphalt concrete anti-stripping agent finished product. The anti-stripping agent can be mutually soluble with asphalt, can obviously enhance the adhesiveness of the asphalt and acid aggregate, improves the water stability and heat stability of asphalt concrete, and can meet the construction of the acid aggregate of a seepage-proofing panel of a pumped storage power station.
本发明提供了一种沥青混凝土抗剥落剂及其制备方法，该抗剥落剂包括以下原材料：松香、有机酸酐、聚乙二醇、氢氧化钾；其制备方法如下：将松香、有机酸酐先后投入反应釜进行缩合反应，然后加入聚乙二醇进行酯化反应、加入碱进行皂化反应，产物冷却后粉碎为颗粒，得沥青混凝土抗剥落剂成品。该抗剥落剂可与沥青互溶，能显著增强沥青与酸性骨料的黏附性，提高沥青混凝土的水稳定性及热稳定性，可满足抽水蓄能电站防渗面板酸性骨料施工。
