Gypsum plaster board capable of releasing negative oxygen ions and preparation method thereof
The invention discloses a gypsum plaster board capable of releasing negative oxygen ions and a preparation method thereof. The gypsum plaster board comprises semi-hydrated industrial by-product gypsumand tourmaline powder, wherein the semi-hydrated industrial by-product gypsum is selected from any one or two of semi-hydrated phosphogypsum and semi-hydrated desulfurized gypsum. The preparation method comprises the following steps of: adding the semi-hydrated industrial byproduct gypsum, water, a binder, tourmaline powder, glass fibers and a water reducing agent into a mixer, and uniformly stirring to obtain first slurry; adding a foaming agent into the first slurry, and uniformly stirring to obtain second slurry; and combining the second slurry with upper and lower surface protection paperfor molding, cutting and drying to obtain the gypsum plaster board. The gypsum plaster board can release more negative oxygen ions, has the function of purifying the environment, and is simple in preparation process and low in cost.
一种可释放负氧离子的纸面石膏板及其制备方法。所述纸面石膏板包括半水工业副产石膏和电气石粉末，所述半水工业副产石膏选自半水磷石膏和半水脱硫石膏中的任意一种或两种。所述制备方法包括：将半水工业副产石膏、水、粘结剂、电气石粉末、玻璃纤维和减水剂加入混合机中，搅拌均匀后得到第一料浆；将发泡剂加入所述第一料浆中，搅拌均匀后得到第二料浆；将所述第二料浆与上、下护面纸结合成型，切割，干燥，得到所述纸面石膏板。本申请的纸面石膏板可以释放出较多的负氧离子，具有净化环境的功能，而且制备工艺简单，成本低。
