Additive, light plastering gypsum and preparation method of light plastering gypsum
The invention discloses an admixture, light plastering gypsum and a preparation method thereof, and belongs to the technical field of gypsum. The admixture comprises an air entraining agent and a stabilizer. The light plastering gypsum comprises the following components in parts by weight: 0-500 parts of filler, 0-10 parts of a water-retaining agent, 0-5 parts of a retarder, 0.1-10 parts of an additive and the balance of gypsum, wherein the total weight of the components is 1000 parts. The preparation method of the lightweight plastering gypsum comprises the following steps: sequentially putting the gypsum powder, the filler, the water-retaining agent, the retarder and the additive into a mixer, and mixing to obtain the lightweight plastering gypsum. When the admixture provided by the invention is added into gypsum, light plastering gypsum can be obtained under the condition that light aggregate is not used, the mixing time can be shortened to 4 minutes, the procedure of overlay gypsum is reduced in interior wall construction, and the strength is higher.
本发明公开一种外加剂、轻质抹灰石膏及其制备方法，属于石膏技术领域。该外加剂，包括引气剂和稳定剂。该轻质抹灰石膏，按照重量份数共计1000份计算，包括填料0～500份，保水剂0～10份，缓凝剂0～5份，外加剂0.1～10份，其余为石膏。该轻质抹灰石膏的制备方法，包括以下步骤：依次将石膏粉、填料、保水剂、缓凝剂和外加剂投入混合机中混合得到。本发明提出的外加剂添加至石膏中在不使用轻集料的情况下能够得到轻质抹灰石膏，可缩短混合的时间至4min，内墙施工中减少罩面石膏工序，强度更高。
