Preparation method of high-waterproof plastering gypsum
The invention relates to a preparation method of high-waterproof plastering gypsum, and belongs to the technical field of building materials. A paraffin emulsion and a rosin emulsion are added, and the high-waterproof plastering gypsum is prepared. Paraffin is a hydrophobic high-molecular compound, and paraffin is prepared into the emulsion, so that the compatibility with gypsum can be effectivelyimproved, and thus the waterproof effect is ensured; paraffin can be uniformly dispersed in water after being emulsified; when the paraffin emulsion is doped into semi-hydrated gypsum in a hydrationhardening process and mixed, the semi-hydrated gypsum reacts with water in the paraffin emulsion, water in hydrophobic substances is consumed, the hydrophobic substances are immediately and uniformlydispersed in the slurry and is combined with the surface of the gypsum, hydrophobic groups face outwards, a layer of waterproof film is formed on the surface of a gypsum hardened body structure to prevent moisture from invading, and thus the waterproof purpose is further achieved; rosin coats the surface of the gypsum with the hydrophobic groups in the semi-hydrated gypsum hydration hardening process to form a hydrophobic film to improve the waterproofness of a gypsum product.
本发明涉及一种高防水粉刷石膏的制备方法，属于建筑材料技术领域。本发明通过添加石蜡乳液和松香乳液，制备一种高防水粉刷石膏，石蜡是憎水性高分子化合物，将石蜡制成乳液可以有效提高其与石膏的相容性，从而保证防水效果，石蜡经过乳化后可在水中均匀的分散，当半水石膏在水化硬化的过程中掺入石蜡乳液并混合后，半水石膏与石蜡乳液中的水反应，消耗掉憎水物质中水，憎水物质立即均匀分散在浆体内，与石膏表面相结合，疏水基团朝外，在石膏硬化体结构的表面形成一层防水膜阻隔水分的侵入，进而达到防水的目的，松香在半水石膏水化硬化过程中憎水基包覆在石膏表面形成憎水膜来提高石膏制品的防水性。
