Preparation method of composite dry-mixed mortar additive
The invention relates to a preparation method of a composite dry-mixed mortar additive. The composite dry-mixed mortar additive is prepared by taking fly ash as a carrier and taking a thickening agent, a tackifier, an air entraining agent, a retarder and an early strength agent as raw materials through compounding. The dry-mixed mortar additive disclosed by the invention is simple in preparation method, good in stability, small in mixing amount and capable of effectively improving the water retention rate and cohesiveness of mortar and improving the strength of the mortar and the bonding force of the mortar and a base layer, so that the phenomena of wall cracking and hollowing are prevented.
本发明涉及一种复合型干混砂浆添加剂的制备方法：用粉煤灰当载体，以增稠剂，增粘剂，引气剂，缓凝剂，早强剂为原料复配得到。本发明公开的干混砂浆添加剂制备方法简单，稳定性好，掺量小，能有效改善砂浆的保水率和黏聚性，提高砂浆的强度以及与基层的粘结力，从而防止墙面开裂、空鼓的现象发生。
