The invention belongs to the field of building materials, and particularly relates to light moisture-resistant sound-insulation plastering gypsum. The light moisture-resistant sound-insulation plastering gypsum comprises gypsum, cement, calcium powder, vitrified micro bubbles, cellulose ether, an additive and functional resin, wherein the functional resin is a styrene thermoplastic elastomer, andthe addition weight of the functional resin accounts for 12-20% of the addition weight of the gypsum. The plastering gypsum obtained by the invention not only has the advantages of no hollowing, soundabsorption performance, flame retardance, heat insulation, impact resistance and environmental protection performance, but also has water resistance and no powder falling, and has no macroscopic cracks and no powder falling even under the conditions of high air temperature and high air speed at a construction site in summer.
本发明属于建筑材料领域，尤其是涉及一种轻质耐潮隔音抹灰石膏，包括石膏、水泥、钙粉、玻化微珠、纤维素醚、添加剂、功能树脂，其中，所述功能树脂为苯乙烯系热塑性弹性体，所述功能树脂的加入重量占所述石膏加入重量的12～20％。本发明所得到的抹灰石膏，其不仅具有不空鼓、吸音、阻燃、隔热、抗冲击、绿色环保的优点，而且耐水性、不掉粉，即使在夏天施工现场气温高，风速大的情况下，仍然没有肉眼可见的裂纹，也没有掉粉情况。
