Concrete mortar anti-cracking admixture and preparation method thereof
The invention relates to a concrete mortar anti-cracking admixture and a preparation method thereof, and belongs to the technical field of mortar admixtures. The concrete is prepared from a water reducing agent, modified pyrophyllite powder, an admixture, sodium stearate, diethanol amine, an air entraining agent, deionized water, a polyacrylate emulsion, a thickening agent, a plastic expanding agent, rubber powder and a sodium gluconate retarder. According to the concrete mortar anti-cracking admixture and the preparation method thereof, the problems that traditional wet-mixed mortar is prone to bleeding, large in dry shrinkage, prone to cracking, poor in water-retaining property, low in compression strength and breaking strength and the like are solved, the durability, water resistance, seepage resistance, cracking resistance and compression resistance of concrete are integrated, and the concrete mortar anti-cracking admixture is simple in preparation process, convenient to operate and suitable for industrial production. And the production cost is low.
本发明涉及一种混凝土砂浆抗裂外加剂及其制备方法，属于砂浆外加剂技术领域。其包括：减水剂、改性叶腊石粉、掺合料、硬脂酸钠、二乙醇胺、引气剂、去离子水、聚丙烯酸酯乳液、增稠剂、塑性膨胀剂、胶粉、葡萄糖酸钠缓凝剂。本发明提供一种混凝土砂浆抗裂外加剂及其制备方法，其了传统湿拌砂浆存在的易泌水、干缩大、易开裂、保水性差、抗压抗折强度低等缺陷的问题，提高了混凝土的耐久性，防水、抗渗、抗裂、抗压于一体，且本发明制备工艺简单，操作便利，生产成本较低。
