Method for harmlessly applying aluminum electrolysis waste refractory material to preparation of asphalt mixture
The invention provides a method for harmlessly applying an aluminum electrolysis waste refractory material to preparation of an asphalt mixture, which comprises the following steps: precipitating the aluminum electrolysis waste refractory material with calcium salt, treating with a biological material chitosan, carrying out acid and alkali resistance treatment with glutaraldehyde, and finally carrying out super-hydrophobic modification. And heating the obtained surface organic super-hydrophobic aluminum electrolysis waste refractory material, asphalt and coarse and fine aggregate, and mixing in an asphalt mixture stirrer. The method endows the aluminum electrolysis waste refractory material with acid and alkali resistant environment stability and non-polar end groups, has excellent adhesion performance with asphalt, and effectively controls the exudation of the toxicity of the aluminum electrolysis waste refractory material, so that the aluminum electrolysis waste refractory material can be safely applied to an asphalt mixture, and the service life of the aluminum electrolysis waste refractory material is prolonged. Meanwhile, the high-temperature stability and the water stability of the asphalt mixture are remarkably improved, and remarkable social benefits and environmental protection benefits are achieved.
本发明提供一种铝电解废旧耐火材料无害化应用于制备沥青混合料的方法，将铝电解废旧耐火材料经钙盐沉淀后再利用生物材料壳聚糖进行处理，再利用戊二醛进行耐酸碱处理，最后进行超疏水改性，得到的表面有机超疏水化铝电解废旧耐火材料和沥青、粗细骨料加热后于沥青混合料搅拌机中进行拌合。该方法赋予铝电解废旧耐火材料耐酸碱环境的稳定性和非极性端基，与沥青具有优异的粘附性能，有效控制了铝电解废旧耐火材料本身毒性的渗出，使其在沥青混合料中能够安全应用，同时显著提高了沥青混合料的高温稳定性能和水稳定性能，具有显著的社会效益和环保效益。
