Phase change ice and snow melting steel slag aggregate, asphalt mixture and preparation method of phase change ice and snow melting steel slag aggregate
The invention relates to a phase-change ice and snow melting steel slag aggregate, an asphalt mixture and a preparation method of the phase-change ice and snow melting steel slag aggregate. The phase change ice and snow melting steel slag aggregate provided by the invention is prepared from the following raw materials in parts by weight: 90 to 110 parts of eutectic phase change material, 190 to 210 parts of steel slag, 90 to 110 parts of modifier, 290 to 310 parts of styrene-acrylic emulsion, 180 to 200 parts of cement and 8 to 12 parts of silica fume. According to the preparation method provided by the invention, the modified steel slag adsorbed with the phase-change material is secondarily packaged by adopting the styrene-acrylic emulsion and the modified cement slurry, so that the problem that the steel slag aggregate containing the phase-change material and the asphalt mixture thereof are easy to leak in the use process is effectively solved. Through the synergistic effect of all the raw material components, the asphalt mixture can be endowed with excellent temperature adjusting and ice melting functions, and active melting of ice and snow on an asphalt pavement in winter is achieved. Meanwhile, the invention provides a way for high-value utilization of the steel slag, the problem that the stacking amount of the waste steel slag is large is effectively relieved, and good economic benefits are achieved.
本申请涉及一种相变融冰雪钢渣集料、沥青混合料及其制备方法。本申请提供的相变融冰雪钢渣集料由以下重量份的原料组成，共晶相变材料90～110份，钢渣190～210份、改性剂90～110份，苯丙乳液290～310份，水泥180～200份，微硅粉8～12份。本申请提供的制备方法采用苯丙乳液和改性水泥浆液对吸附有相变材料的改性钢渣进行二次封装，有效解决了含有相变材料的钢渣集料及其沥青混合料在使用过程中易发生泄露的难题。本申请各原料组分的协同作用，可以赋予沥青混合料优良的调温和融冰功能，实现冬季沥青路面冰雪主动消融。同时，本申请提供了一种高值化利用钢渣的途径，有效缓解废弃钢渣堆存量庞大的问题，具有良好的经济效益。
