Cement toughening and reinforcing agent and preparation method thereof
The invention relates to a cement toughening and reinforcing agent and a preparation method thereof, and belongs to the technical field of cement. The invention discloses a cement toughening enhancer, which is prepared from the following components in percentage by mass: 10 to 25 percent of ordinary Portland cement, 12 to 50 percent of salt, 24 to 32 percent of water reducing agent, 8 to 35 percent of gypsum, 3 to 10 percent of slaked lime, 0.5 to 1 percent of modified polyvinyl alcohol, 0.06 to 0.12 percent of defoaming agent, 0.2 to 0.4 percent of lauryl sodium sulfate and 0.2 to 0.4 percent of hydroxypropyl methyl cellulose, and also discloses a preparation method of the cement toughening enhancer. All the components are weighed according to the mass percent and are mixed to obtain the cement toughening and reinforcing agent. After polyvinyl alcohol is modified, the modified polyvinyl alcohol is mixed with other additives to prepare the multifunctional cement concrete additive, and the multifunctional cement concrete additive is good in compounding effect, high in practicability and low in cost.
本发明涉及一种水泥增韧增强剂及其制备方法，属于水泥技术领域。公开了一种水泥增韧增强剂，包括以下组分，配比方式以质量百分比计，10～25%的普通硅酸盐水泥、12～50%的盐、24～32%的减水剂、8～35%的石膏、3～10%的熟石灰、0.5～1%的改性聚乙烯醇、0.06～0.12%的消泡剂、0.2～0.4%的十二烷基硫酸钠、0.2～0.4%的羟丙基甲基纤维素，同时公开了其制备方法，对聚乙烯醇进行改性，按照质量百分比称重各组分，混合得到水泥增韧增强剂。通过对聚乙烯醇进行改性后，与其他添加剂进行混配，制备成多功能性水泥混凝土添加剂，复配效果好、实用性强、成本低。
