Homogeneous self-heat-preservation building block taking gold tailings as raw material and preparation method of homogeneous self-heat-preservation building block
The invention relates to a homogeneous self-insulation building block taking gold tailings as a raw material and a preparation method of the homogeneous self-insulation building block, belongs to the technical field of solid waste resourceful treatment, and solves at least one of the problems of resource waste, environmental pollution and the like caused by insufficient recycling of the gold tailings and direct discarding of the gold tailings in the prior art. The invention provides a homogeneous thermal insulation building block taking gold tailings as a raw material. The homogeneous thermal insulation building block comprises the gold tailings, cement, water, an additive, a foaming agent and polyphenyl foam particles. According to the homogeneous self-heat-preservation building block, efficient recycling of the gold tailings is achieved, resource waste and environmental pollution are avoided, the prepared homogeneous self-heat-preservation building block is excellent in performance and meets the national building standards GB/T 11969-2020 and GB/T10294-2008, the compressive strength (MPa) is larger than 5.0, the average dry density (kg/m < 3 >) is 630-730, the dry-state heat conductivity coefficient (W/m.K) is smaller than 0.12, and the homogeneous self-heat-preservation building block is suitable for being used as a building block. The material can be widely applied to external wall heat insulation, refrigeration house heat insulation, ground and roof heat insulation layers and other scenes.
本发明涉及一种以黄金尾矿为原料的均质自保温砌块及其制备方法，属于固废资源化处理技术领域，解决了现有技术中黄金尾矿回收利用不充分、直接丢弃会造成资源浪费和环境污染等问题中的至少一个。本发明提供了一种以黄金尾矿为原料的均质保温砌块，包括黄金尾矿、水泥、水、外加剂、发泡剂、聚苯泡沫颗粒。上述均质自保温砌块实现了黄金尾矿的高效回收利用，免了资源浪费和环境污染，且制备的均质自保温砌块性能优异，符合国家建筑标准GB/T 11969‑2020和GB/T10294‑2008，抗压强度(MPa)＞5.0，平均干密度(kg/m3)：630～730，干态导热系数(W/m·K)＜0.12，可广泛应于外墙保温、冷库隔热、地面屋面隔热层等场景。
