传统的抹灰砂浆采用主要原料为乙氧基化烷基硫酸钠、膨润土，在使用上存在明显缺陷如墙体龟裂、粘结处形成空鼓。
发明内容
本发明为克服上述现有技术中抹灰砂浆容易导致墙体龟裂、粘结处形成空鼓的不足。提供一种能够提高施工质量、避免抹灰后墙体龟裂、起鼓的砂浆增稠剂及其制备方法。
本发明的技术方案如下：
砂浆增稠剂由下述质量分数计的原料组成：
减水剂：10-35份
保水剂：20-30份
纤维素醚：15-25份
填充剂：30-70份；
其中所述减水剂为β-奈磺酸甲醛缩合物钠盐、木质素磺酸钠盐、磺化丙酮-甲醛缩合物或糖钙减水剂；其中所述保水剂为聚乙二醇，其中所述纤维素醚为HK100000s、HK80000s、HK150000s、HK40000s的纤维素醚；其中所述填充剂为石灰石粉、粉煤灰或矿粉。
砂浆增稠剂的制作方法：
将上述比例的原料混合，经搅拌均匀即可得到砂浆增稠剂。
