Preparation method of diatomite-based building humidifying material
The invention provides a preparation method of a diatomite-based building humidifying material, and relates to the field of humidifying materials, and the method comprises the following steps: refining diatomite; preparing inorganic salt modified diatomite; mixing the inorganic salt modified diatomite with bentonite and straw fibers, then adding the mixture into emulsion, carrying out ultrasonic oscillation for 5-15 minutes, uniformly dispersing microcrystalline wax into the emulsion, heating to 40-50 minutes, filtering out, and carrying out wet pressing molding to obtain a blank; transferringthe blank into a hydrothermal reaction kettle, performing hydrothermal treatment for 5 to 10 hours at a temperature of 120 to 150 DEG C and a saturated vapor pressure of 0.5 to 1.2 MPa, and aging for10 to 20 days.The diatomite-based building humidifying material has the advantages that the mechanical strength is excellent, in addition, the moisture absorption and desorption performance is good,the moisture absorption rate reaches 23.2 percent, the moisture desorption rate reaches 19.1 percent, and the function of adjusting the air humidity is realized.
本发明提供一种硅藻土基建筑调湿材料的制备方法，涉及调湿材料领域，包括以下步骤：精制硅藻土；制备无机盐修饰硅藻土；将无机盐修饰硅藻土与膨润土、秸秆纤维混合后加入乳化液中超声震荡5‑15min，将微晶石蜡均匀分散在乳化液升温至40‑50min，滤出湿压成型后得到胚体；将胚体转移进入水热反应釜中，在温度为120‑150℃，压强为0.5‑1.2MPa的饱和蒸汽压下水热处理5‑10h后陈化10‑20d即可，本发明硅藻土基建筑调湿材料的力学强度优异，而且吸放湿性能良好，其中吸湿率达到23.2％，放湿率达到19.1％，具有调节空气湿度的功能。
