The invention discloses environment-friendly quick-setting modified gypsum sand with a heat preservation function, and belongs to the technical field of gypsum sand, and the environment-friendly quick-setting modified gypsum sand is prepared from the following raw materials: desulfurized gypsum, fly ash, construction waste residues, vitrified micro bubbles, ceramic polishing powder, an anti-cracking agent, rubber powder, a water-retaining agent, quartz sand, sawdust powder, shell powder, nano calcium carbonate, a water reducing agent, a defoamer and carboxypropyl methyl cellulose. The defoaming agent is a special defoaming agent for gypsum; the mesh number of the quartz sand is 100-200 meshes; the content ratio of SiO2 to Al2O3 in the ceramic polishing powder is 4: 1. By limiting the components and the preparation method of the gypsum sand, the performance of the gypsum sand is further improved; the fly ash, the sawdust powder, the shell powder and the nano calcium carbonate are matched with one another to provide heat preservation performance for the gypsum sand; fly ash and construction waste slag are used as raw materials, so that waste utilization is realized, and environmentalprotection is realized; meanwhile, the environment-friendly quick-setting modified gypsum sand has excellent mildew-proof and anti-cracking performance, good thermal insulation performance, low costand high practicability.
本发明公开了一种具有保温功能的环保型速凝改性石膏砂，属于石膏砂技术领域，以原料组成：脱硫石膏、粉煤灰、建筑废料渣、玻化微珠、陶瓷抛光粉、抗裂剂、胶粉、保水剂、石英砂份、木屑粉、贝壳粉、纳米碳酸钙、减水剂、消泡剂、羧丙基甲基纤维素；消泡剂为石膏专用消泡剂；石英砂目数为100‑200目；陶瓷抛光粉中SiO2与Al2O3含量比例为4：1。本发明通过限定石膏砂的组分与制备方法，进而提高了石膏砂的性能；粉煤灰、木屑粉、贝壳粉、纳米碳酸钙之间相配合，为石膏砂提供保温性能；利用粉煤灰与建筑废料渣为原材料，实现废物利用，绿色环保；同时具有优良的防霉防裂性能，保温性能好，成本低，实用性强。
