Phase-change high-strength gypsum powder synthesized through seed crystal induction and preparation method of phase-change high-strength gypsum powder
The invention discloses phase-change high-strength gypsum powder synthesized through seed crystal induction and a preparation method of the phase-change high-strength gypsum powder. The preparation method comprises the following steps: (1) mixing and emulsifying a molten phase change material, a surfactant and water, and dropwise adding a mixed metal salt solution to obtain a seed crystal prefabricated solution; (2) mixing the seed crystal pre-prepared liquid obtained in the step (1), gypsum powder and water, and reacting to obtain a phase-change high-strength gypsum pre-polymerized liquid; and (3) filtering, washing and drying the phase-change high-strength gypsum prepolymerization liquid obtained in the step (2) to obtain the phase-change high-strength gypsum powder. The method provided by the invention is simple in operation process, green and environment-friendly, and the obtained high-strength gypsum powder is high in purity and controllable in morphology and particle size, has heat storage and temperature regulation functions, mechanical properties and antibacterial properties, and is wide in application range.
本发明公开了一种晶种诱导合成相变高强石膏粉及其制备方法。其中,所述制备方法,包括以下步骤:(1)将熔融态相变材料、表面活性剂和水混合乳化后,逐滴加入混合金属盐溶液,得到晶种预制液;(2)将步骤(1)的晶种预制液、石膏粉和水混合,进行反应,得到相变高强石膏预聚液;(3)对步骤(2)的相变高强石膏预聚液过滤、洗涤、干燥,得到所述相变高强石膏粉。本发明提供的方法操作工艺简单、绿色环保,所得高强石膏粉的纯度高且形貌、粒径可控,具备蓄热调温功能、力学性能和抗菌性能,适用范围广。
