Coal gangue modified bottom layer plastering gypsum and preparation method thereof
The invention discloses coal gangue modified bottom layer plastering gypsum and a preparation method thereof. The raw materials comprise 300-400 parts of flue gas desulfurization gypsum, 400-600 parts of river sand, 100-200 parts of coal gangue powder, 1.2-1.5 parts of a retarder, 1.5-2.5 parts of methyl cellulose, and 0.3-0.6 part of starch ether; the component A comprises desulfurized gypsum, river sand and coal gangue powder, and the component B comprises methyl cellulose, a retarder and starch ether; adding coal gangue powder into the substance B, uniformly mixing, and then mixing with the substance A to obtain a mixture; and adding the obtained mixture into water according to a water-cement ratio of 0.3-0.4, and uniformly stirring to obtain the product. According to the invention, the comprehensive utilization of coal gangue resources is realized, the environmental pollution can be reduced, the environmental pollution load can be reduced, the environment can be protected and improved, the energy can be saved, green building materials can be produced, and descendants can be benefited. And the raw material cost of the product can be greatly reduced.
本发明公开一种煤矸石改性底层粉刷石膏及其制备方法。原料组成为：脱硫石膏300‑400，河砂400‑600，煤矸石粉100‑200，缓凝剂1.2‑1.5，甲基纤维素1.5‑2.5，淀粉醚0.3‑0.6；将成分分组为A组：脱硫石膏，河砂，煤矸石粉，B组：甲基纤维素，缓凝剂，淀粉醚；B组物质中加入煤矸石粉混合均匀后再混入A组物质，得到混合物；按水灰比0.3‑0.4将所得混合物加入水中，搅拌均匀即得产品。本发明实现了煤矸石资源化综合利用，不但可以减少环境污染，降低环境污染负荷，保护和改善环境，节约能源，生产绿色建材，而且还可以造福子孙后代。并且可以大幅降低产品的原材料成本。
