Gypsum-based antibacterial material as well as preparation method and application thereof
The invention discloses a gypsum-based antibacterial material as well as a preparation method and application thereof. The invention relates to the technical field of antibacterial materials. The preparation method comprises the following steps: mixing gypsum powder and dispersion liquid according to a certain solid-to-liquid ratio, and fully stirring to obtain first slurry; adding a certain amount of a crystal phase transition agent and a crystal morphology guiding agent into the first slurry, and stirring and reacting for a period of time to obtain second slurry; adding an antibacterial precursor into the second slurry, regulating the pH value of the slurry to be acidic, and stirring for reaction to obtain third slurry; and filtering, washing, drying and crushing the third slurry to obtain the gypsum-based antibacterial material. The relative texture coefficient of the 204 crystal face of the gypsum-based antibacterial material is greater than 0.1. According to the invention, the alpha-CaSO4. 5H2O material with intrinsic antibacterial activity is prepared through gypsum crystal transformation and in-situ structure regulation and control.
本发明公开了一种石膏基抗菌材料及其制备方法和应用。本发明涉及抗菌材料技术领域。制备如下:将石膏粉体与分散液按一定的固液比混合,充分搅拌得到第一浆料;向第一浆料中加入一定量晶相转变剂和晶体形貌导向剂,搅拌反应一段时间得到第二浆料;向第二浆料中加入抗菌前驱体,调控浆料pH值至酸性,搅拌反应得到第三浆料;将第三浆料过滤、洗涤、干燥、粉碎,得到所述石膏基抗菌材料;所述石膏基抗菌材料的204晶面的相对织构系数大于0.1。本发明通过石膏转晶及原位结构调控制备具有本征抗菌活性的α‑CaSO4·0.5H2O材料。
