High-thermal-conductivity energy-storage backfill material as well as preparation method and application thereof
The invention belongs to the technical field of multifunctional building materials, and provides a high-thermal-conductivity energy-storage backfill material and a preparation method and application thereof.The high-thermal-conductivity energy-storage backfill material is prepared from, by mass, 2-3 parts of aggregate, 0.3-0.8 part of drilling mud and 0.8-1.2 parts of a curing agent, the preparation proportion of the aggregate is adjusted, then the aggregate is matched with the specific curing agent, and the high-thermal-conductivity energy-storage backfill material is prepared. The backfill material has excellent heat-conducting property; the quartz sand and the waste iron tailing sand in mining are recycled and mixed with the drilling mud and the curing agent according to a certain proportion to prepare the high-thermal-conductivity energy-storage backfill material, the manufacturing cost is saved, and the ecological environment is protected. Tests show that the 28d compressive strength of the high-thermal-conductivity energy-storage backfill material prepared by the method can reach 1.94 MPa at most, the thermal conductivity coefficient can reach 2.374 W/(m.k) at most, and the thermal conductivity coefficient is increased by 1.581 times compared with that of a single curing agent.
本发明属于多功能建筑材料技术领域，提供了一种高导热储能回填材料及其制备方法和应用，该储能回填材料由包含下列质量份数的原料制备得到：骨料2～3份、钻井泥浆0.3～0.8份、固化剂0.8～1.2份，通过调整骨料的配置比例，再与特定的固化剂搭配，使得回填材料具有优异的导热性能；本发明将石英砂以及矿山开采中废弃的铁尾矿砂回收利用，与钻井泥浆、固化剂按一定的比例混合制备高导热储能回填材料，节省成本造价，生态环境得到保护。经测试本发明制备得到的高导热储能回填材料，28d抗压强度最高可达1.94MPa，导热系数最高可达2.374W/(m·k)，相比于单一固化剂，导热系数提高了1.581倍。
