Low-cost light plastering gypsum mortar and preparation method thereof
The invention discloses a low-cost light plastering gypsum mortar and a preparation method thereof, the low-cost light plastering gypsum mortar comprises gypsum mortar, 50-70 parts of gypsum powder, 25-45 parts of hydrated calcium silicate powder, 0.1-0.2 part of thixotropic lubricant, 0.1-0.2 part of water-retention thickener and 2-4 parts of vitrified microbead, the gypsum powder is alpha-type and beta-type gypsum powder prepared from natural gypsum or industrial byproduct gypsum, the thixotropic lubricant is a thixotropic lubricant, the water-retention thickener is a thixotropic lubricant, the thixotropic lubricant is a thixotropic lubricant, and the vitrified microbead is a thixotropic lubricant. Wherein the 2h breaking strength of the alpha-type gypsum powder is greater than 5Mpa, and the 2h compressive strength of the alpha-type gypsum powder is greater than 15Mpa, the 2h breaking strength of the beta-type gypsum powder is greater than 3Mpa, and the 2h compressive strength of the beta-type gypsum powder is greater than 6Mpa, the gypsum powder is used as a main gel material, the hydrated calcium silicate powder is used as a filling material, and the glass beads are used as a light material. According to the plastering gypsum mortar material disclosed by the invention, the recycling of resources is realized by utilizing calcium silicate board leftover material powder and polishing and sanding dust collection in a calcium silicate board factory, and the plastering gypsum mortar material has the characteristics of large unit coating area, good water-retaining property, breaking strength and compressive strength, heat preservation, heat insulation, fire resistance and the like, and is low in production cost and simple in preparation method.
本发明公开了一种低成本轻质抹灰石膏砂浆及其制备方法,包括石膏砂浆，石膏粉50～70份、水化硅酸钙粉末25～45份、触变润滑剂0.1～0.2份、保水增稠剂0.1～0.2份、玻化微珠2～4份，石膏粉为天然石膏或者工业副产石膏制备的α型和β型石膏粉，其中α型石膏粉2h抗折强度大于5Mpa，2h抗压强度大于15Mpa，β型石膏粉2h抗折强度大于3Mpa，2h抗压强度大于6Mpa，该材料以石膏粉为主要凝胶材料，以水化硅酸钙粉末作为填充材料、以玻化微珠作为轻质材料，利用硅酸钙板厂硅酸钙板边角料粉末和抛光砂磨粉尘收集物，实现了资源的循环利用，该抹灰石膏砂浆材料单位涂覆面积大、保水性、抗折强度、抗压强度好，具有保温、隔热、耐火等特点，生产成本低，制备方法简单。
