Preparation method of modified oyster shell antibacterial calcium silicate board
The invention relates to a preparation method of a modified oyster shell antibacterial calcium silicate board. The method comprises the following steps: soaking biomass waste oyster shells in a Cu (NO3) 2.3 H2O solution, filtering, and calcining the obtained solid to obtain CuO/CaO powder; adding water to hydrate the CuO/Ca (OH) 2 powder to obtain CuO/Ca (OH) 2 powder; mixing the mixture with diatomite, then adding fibers and ordinary Portland cement to obtain mixed powder, and then adding water and stirring to obtain slurry; and carrying out compression molding and autoclaved curing to obtain the modified oyster shell antibacterial calcium silicate board. According to the preparation method of the calcium silicate board with the modified biological waste oyster shell powder and the diatomite rich in mineral resources as the main raw materials, the whole-body antibacterial effect of the calcium silicate board is achieved, and the problems that traditional building materials are serious in pollution, lack of resources and the like are solved.
本发明为一种改性海蛎壳抗菌硅酸钙板制备方法。该方法通过将生物质废弃物海蛎壳浸泡在Cu(NO3)2·3H2O溶液中，经过滤后将所得固体煅烧，得到CuO/CaO粉末；再加水使其水化，得到CuO/Ca(OH)2粉末；将其和硅藻土进行混合，再加入纤维、普通硅酸盐水泥，得到混合粉体，然后再加入水搅拌，得到浆料；经模压成型，蒸压养护，得到改性海蛎壳抗菌硅酸钙板。本发明以改性生物废弃物海蛎壳粉及矿产资源丰富的硅藻土为主要原材料的硅酸钙板制备方法，实现了硅酸钙板的通体抗菌功效，解决了传统建材污染严重，资源匮乏等问题。
