The invention discloses lightweight plastering gypsum mortar and a preparation method thereof. The preparation method comprises the following steps of preparing gypsum powder: grinding gypsum to obtain gypsum powder with uniform fineness; preparing starch ether: carrying out a silicon etherification reaction on starch serving as a raw material with a copper salt as a catalyst by means of a reaction kettle and ultrasonic waves to obtain the starch ether; preparing a raw material mixture: pouring the gypsum powder, the starch ether, cement, fly ash and a water-retaining agent into a mixing device, and uniformly mixing; and preparing plastering gypsum: fully mixing the mixture obtained in the third step and aggregate again to obtain the plastering gypsum. According to the lightweight plastering gypsum mortar and the preparation method thereof, the effect of improving the comprehensive capacity is achieved, the thickening capacity is good, meanwhile the influence of humid weather is reduced, the quality problems of hollowing, cracking, surface dusting or falling are not prone to occurring, the service life of a building is prolonged, and the use performance is improved.
本发明公开了一种轻质抹灰石膏砂浆及其制备方法，由以下步骤组成：制备石膏粉：将石膏进行磨粉处理，得到细度均匀的石膏粉；制备淀粉醚：淀粉为原料，并通过铜盐为催化剂，并借助反应釜和超声波对淀粉进行硅醚化反应，得到淀粉醚；制备原料混合物：石膏粉、淀粉醚、水泥、粉煤灰、保水剂倒入混料装置中，进行均匀混合；制备抹灰石膏：将步骤三中的混合和集料进行再次充分混合，得到抹灰石膏，本发明涉及建筑材料技术领域。该轻质抹灰石膏砂浆及其制备方法，达到了提高综合能力的效果，增稠能力好，同时减少受潮湿天气的影响，不易出现空鼓、开裂、表面起灰或脱落的质量问题，延长了建筑物的使用寿命，提高了使用性能。
