Process method for preparing cement and fireproof coating from brucite mineral powder and monopotassium phosphate
The invention discloses a process method for preparing cement and a fireproof coating by utilizing brucite ore powder and monopotassium phosphate. Natural brucite ore is pretreated by different processes so as to completely replace dead burned magnesium oxide prepared by high-temperature calcination to prepare potassium magnesium phosphate cement. The brucite powder treated by different processes is introduced in the preparation process of the magnesium phosphate cement, so that the binding power of the magnesium phosphate cement is increased, the coagulation and hardening processes of the magnesium phosphate cement are promoted, and a uniform colloid is formed in a magnesium phosphate cement system to improve the shock resistance and durability of the magnesium phosphate cement. The magnesium potassium phosphate cement provided by the invention not only meets the requirements of related technical indexes, but also has the characteristics of low cost, good adhesive property and better mechanical property, is low-carbon, environment-friendly and pollution-free, and also has the advantage of optimizing the hydration heat release temperature and the setting time of the magnesium potassium phosphate cement.
本发明公开了一种利用水镁石矿粉和磷酸二氢钾制备水泥及防火涂料的工艺方法，通过不同工艺对天然水镁石矿石进行预处理以便完全替代高温煅烧制备的重烧氧化镁制备磷酸钾镁水泥。本发明通过在磷酸镁水泥制备过程中引入不同工艺处理的水镁石粉体，增加磷酸镁水泥的的粘结力，促进磷酸镁水泥的凝结和硬化过程，其次在磷酸镁水泥体系中形成一个均匀的胶状体改善磷酸镁水泥的抗震性和耐久性。本发明所提供的磷酸钾镁水泥不仅满足相关技术指标的要求，还具有成本低廉、粘结性能好、力学性能较好的特点，且低碳环保无污染，对优化磷酸钾镁水泥的水化放热温度和凝结时间也有优势。
