Ceramic tile adhesive with waterproof function

The invention relates to a ceramic tile adhesive with a waterproof function, and belongs to the technical field of building materials. The ceramic tile adhesive with the waterproof function is prepared from ordinary Portland cement, quartz sand or dry river sand, cellulose ether, superfine silica fume powder, redispersible latex powder, a higher fatty acid waterproof agent, organic silicon powder and starch ether in an optimized manner. According to the invention, the superfine silica fume powder, the redispersible latex powder, the higher fatty acid waterproof agent and the organic silicon powder are creatively added into the raw materials of the ceramic tile adhesive at the same time, so that the bonding strength and the waterproof performance of the ceramic tile adhesive can be synergistically enhanced. 本发明涉及一种具有防水功能的陶瓷砖胶粘结剂，属于建筑材料技术领域。本发明具有防水功能的陶瓷砖胶粘结剂由普通硅酸盐水泥、石英砂或干河沙、纤维素醚、超细硅灰粉、可再分散乳胶粉、高级脂肪酸防水剂、有机硅粉末和淀粉醚优化配置制备而成。本发明创造性地将超细硅灰粉、可再分散乳胶粉、高级脂肪酸防水剂和有机硅粉末同时加入至陶瓷砖胶粘结剂的原料中，可协同增强陶瓷砖胶粘结剂的粘结强度和防水性能。
