Preparation method of concrete waterproof additive
The invention relates to the technical field of concrete additives, in particular to a preparation method of a concrete waterproof additive, and the concrete waterproof additive is prepared from the following raw materials by mass: 8-10% of organosilicon; 20%-30% of fly ash; 8%-10% of an ammonia-free system styrene acrylate copolymer emulsion; 3%-4% of dodecafluoroheptyl methacrylate; 0.6%-1% of triterpenoid saponin; 0.5%-1.5% of calcium sulfate whiskers; 0.2%-0.5% of tartaric acid; 3%-5% of silicon dioxide aerogel; 2%-5% of sodium diethylene triamine pentacarboxylic acid; 5%-6% of a coalescing agent; 5%-6% of a lignosulfonate water reducing agent; and the balance of water. The waterproof performance of the concrete can be improved, the concrete can be endowed with good strength, corrosion resistance, wear resistance and the like, and the preparation method is simple.
本发明涉及混凝土添加剂技术领域，具体涉及一种混凝土防水添加剂的制备方法，该混凝土防水添加剂由以下质量百分比的原料制备所得：有机硅8％～10％；粉煤灰20％～30％；无氨体系苯乙烯丙烯酸酯共聚乳液8％～10％；甲基丙烯酸十二氟庚酯3％～4％；三萜皂苷0.6％～1％；硫酸钙晶须0.5％～1.5％；酒石酸0.2％～0.5％；二氧化硅气凝胶3％～5％；二乙烯三胺五羧酸钠2％～5％；成膜助剂5％～6％；木质素磺酸盐减水剂5％～6％；余量为水。本发明既能提升混凝土的防水能力，又能赋予混凝土较好的强度、耐蚀和耐磨等性能，且制备方法简单。
