Asphalt anti-stripping agent for tailing aggregate and preparation method of asphalt anti-stripping agent
The invention discloses an asphalt anti-stripping agent for tailing aggregate and a preparation method of the asphalt anti-stripping agent, and the asphalt anti-stripping agent comprises the following components in percentage by mass: 55-65% of tailing powder, 30-40% of lime powder, 3-4% of fatty alcohol polyoxyethylene ether phosphate and 1-2% of a silane coupling agent. The preparation method comprises the following steps: (1) mixing fatty alcohol polyoxyethylene ether phosphate and a silane coupling agent according to a mass ratio of 2: 1, and uniformly stirring to obtain a pre-prepared mixed solution; (2) drying the iron tailing slag, and grinding to 1t; the passing rate of 0.075 mm is 85-100%, adding lime powder, and uniformly mixing to obtain prefabricated mixed powder; and (3) uniformly spraying the pre-prepared mixed solution in the step (1) on the mixed powder in the step (2) according to a ratio of the mixed solution to the mixed powder of 1: (10-15), and drying to obtain the asphalt mixture anti-stripping agent. The asphalt mixture anti-stripping agent can improve the adhesiveness of asphalt and tailing aggregate, improve the water stability of the mixture, and promote the application of the tailing aggregate in road engineering.
本发明公开了一种尾矿集料用沥青抗剥落剂及其制备方法，以质量百分数计，包括如下组分：尾矿粉末55～65%、石灰粉末30～40%、脂肪醇聚氧乙烯醚磷酸酯3～4%、硅烷偶联剂1～2%。制备方法如下：（1）将脂肪醇聚氧乙烯醚磷酸酯和硅烷偶联剂，按质量比为2:1进行混合，搅拌均匀，得预制混合液；（2）将铁尾矿渣烘干，研磨至<0.075mm通过率为85~100%，加入石灰粉末混合均匀，得预制混合粉末；（3）将（1）中预制混合液均匀喷洒在步骤（2）中混合粉末上，混合液和混合粉末的比例为1:（10~15），烘干得到沥青混合料抗剥落剂。该沥青混合料抗剥落剂能够提高沥青与尾矿集料的黏附性，改善混合料的水稳定性，同时促进尾矿集料在路用工程中的应用。
