Low-shrinkage ceramic tile adhesive and preparation process thereof
The low-shrinkage ceramic tile glue comprises the following components in percentage by mass: 30% of low-shrinkage anti-cracking cement, 20% of quartz sand of 20-40 meshes, 20% of quartz sand of 40-70 meshes, 20% of quartz sand of 70-120 meshes, 1-2% of bentonite, 1-2% of kaolin, 1-2% of mineral powder and 1-4% of silica fume powder. The preparation method comprises the following steps: S1, putting required raw materials into an automatic batching system for automatic batching according to a mass percentage, S2, putting macromolecular flexible compound starch and powder prepared in the S1 into a stirrer for mixing and stirring, S3, adding cellulose ether into the stirrer for mixing and stirring after the S2, S4, adding flexible acrylic acid rubber powder into the stirrer for mixing and stirring after the S3, and S5, adding the flexible acrylic acid rubber powder into the stirrer for stirring after the S3. S5, after S4, polyvinyl alcohol is added into a stirrer for mixing and stirring to obtain the ceramic tile glue, the effect of reducing the shrinkage of the ceramic tile glue is effectively achieved, and therefore the problems that due to the fact that the shrinkage of the ceramic tile glue is large, ceramic tiles crack and fall off, and personal safety is threatened are solved.
本发明公开了一种低收缩瓷砖胶及其制备工艺，按质量百分比包括以下成分：低收缩抗裂水泥30％、20‑40目的石英砂20％、40‑70目的石英砂20％、70‑120目的石英砂20％、膨润土1‑2％、高岭土1‑2％、矿粉1‑2％、硅灰粉1‑4％，S1、将所需原料放入自动配料系统按质量百分比进行自动配料，S2、将高分子柔性复配淀粉与S1中配备的粉料放入搅拌机中进行混合搅拌，S3、经S2后加入纤维素醚至搅拌机进行混合搅拌，S4、经S3后加入柔性丙烯酸胶粉至搅拌机进行混合搅拌，S5、经S4后加入聚乙烯醇至搅拌机进行混合搅拌后得出瓷砖胶，有效的达到降低瓷砖胶收缩小的作用，从而解决因瓷砖胶收缩大的原因引起的瓷砖开裂、脱落情况，威胁到人身安全的问题。
