The invention relates to the technical field of floor heating backfilling, in particular to a heat storage type floor heating backfilling cushion layer and application thereof. The heat storage type floor heating backfill cushion comprises the following components in parts by weight: 30-60 parts of fine aggregate concrete, 30-60 parts of graphite tailing sand, 2-6 parts of an expanding agent and 2-6 parts of a combined additive, the expanding agent is an animal protein composite foaming agent, and the combined additive comprises the following components in parts by weight: redispersible rubber powder, polyvinyl alcohol and hydroxypropyl methyl cellulose; the solid waste graphite tailing sand in graphite development is added into the floor heating backfill cushion layer, so that the heat storage coefficient of the floor heating backfill cushion layer can be increased, and meanwhile, the characteristics of small specific gravity and high compressive strength of the floor heating backfill cushion layer are not influenced; by selecting the expanding agent and the combined additive, the floor heating backfill cushion is good in flowability and excellent in mechanical property.
本发明涉及地暖回填技术领域，具体涉及一种蓄热型地暖回填垫层及其应用；所述蓄热型地暖回填垫层按重量份组成包括：细石混凝土30～60，石墨尾矿砂30～60，膨胀剂2～6，组合添加剂2～6；所述膨胀剂选用动物蛋白类复合型发泡剂，所述组合添加剂按重量份组成包括可再分散性胶粉、聚乙烯醇和羟丙基甲基纤维素；本发明中在地暖回填垫层中加入石墨开发中的固体废弃物石墨尾矿砂，能够提升地暖回填垫层蓄热系数，同时不会影响地暖回填垫层的比重小和抗压强度高的特性；本发明中通过膨胀剂和组合添加剂的选用，使得所述地暖回填垫层流动性好，机械性能优异。
