Preparation method and construction process of putty-free plastering gypsum mortar
The invention discloses a preparation method and a construction process of putty-free plastering gypsum mortar. The preparation method comprises the following steps: S1, preparing and screening expanded perlite; s2, weighing rosin, putting the rosin into a container I, adding distilled water, maleic anhydride, sodium hydroxide and dicyclohexylcarbodiimide, heating and stirring, then adding TEA, heating and stirring, then cooling to room temperature, when the solution is completely solidified into a solid, taking out the solid, and grinding the solid into fine particles smaller than 80 microns; s3, taking limestone powder, putting the limestone powder into a container II, adding HPMC, HPS, GR, an air entraining agent and a defoaming agent, then adding the materials prepared in the container I, and carrying out sealed stirring for 2-3 minutes; s4, expanded perlite and the substances in the second container are added into building gypsum, sealed storage is performed, and the putty-free plastering gypsum mortar is obtained. Various industrial by-product gypsum can be used as raw materials of building gypsum, industrial solid waste is fully utilized, and environmental protection is facilitated.
本发明公开了一种免腻子抹灰石膏砂浆的制备方法及其施工工艺，它包括S1：制备并筛选膨胀珍珠岩；S2：称取松香放入容器一内，添加蒸馏水，添加马来酸酐、氢氧化钠和二环己基碳二亚胺，升温并搅拌，然后加入TEA，升温搅拌，然后冷却至室温，当溶液完全凝固为固体时，取出固体，将固体粉磨成小于80μm的细颗粒；S3：取石灰石粉于容器二，添加HPMC、HPS、GR、引气剂、消泡剂，再加入容器一内制备好的物质密闭搅拌2‑3min；S4：在建筑石膏中加入膨胀珍珠岩与容器二内的物质，密封保存，得到免腻子抹灰石膏砂浆。本发明使用各种工业副产石膏均可以作为建筑石膏的原材料，充分利用了工业固废，有利于环境保护。
