Preparation method of macromolecular anti-cracking and anti-seepage mortar modifier
The invention relates to the technical field of cement building mortar modification. The invention discloses a macromolecular anti-cracking and anti-seepage mortar modifier. The modifier is prepared from 3%-5% of a polycarboxylate superplasticizer, 2%-3% of cellulose, 0.5%-1% of rubber powder, 0.015%-0.03% of polyacrylamide, 0.015%-0.03% of sodium polyacrylate, 1%-1.5% of a defoaming agent, 2%-2.5% of an air entraining agent, 3%-5% of sodium gluconate and the balance of nano bubble water. Meanwhile, the invention provides a preparation method of the macromolecular anti-cracking and anti-seepage mortar modifier. According to the invention, the mortar has basic working performances such as workability, cohesiveness and the like, has a certain water retention performance, meets the requirements of long-time construction, has good impermeability, crack resistance and a certain waterproof function, has a certain freeze-thaw resistance, and is suitable for northern cold regions.
本发明涉及水泥建筑砂浆改性技术领域，本发明公开了一种高分子型抗裂抗渗砂浆改性剂，包括聚羧酸减水剂3‑5％、纤维素2‑3％、胶粉0.5‑1％、聚丙烯酰胺0.015‑0.03％、聚丙烯酸钠0.015‑0.03％、消泡剂1‑1.5％、引气剂2‑2.5％、萄糖酸钠3‑5％，其余为纳米气泡水。同时提出了一种高分子型抗裂抗渗砂浆改性剂的制备方法。本发明让砂浆具备和易性、粘结性等基本工作性能，让砂浆具备一定的保水性能，满足长时间施工需求，让砂浆具备良好的抗渗、抗裂性能，具备一定的防水功能，让砂浆具备一定的抗冻融性能，适应北方寒冷地区。
