Concrete waterproof compacting agent and preparation method thereof
The invention belongs to the technical field of building material additives, and particularly relates to a concrete waterproof compacting agent and a preparation method thereof. The concrete waterproof compacting agent is prepared from the following components in percentage by weight, 10%-20% of sodium hydroxide, 8%-12% of sodium sulfide; 2%-5% of sodium thiosulfate; 3%-5% of sulfur; 1.5%-2.5% ofglycerol; 1%-1.5% of triethanolamine oleate; 1.5%-3% of glycerol; and remaining water. The concrete waterproof compacting agent is low in mixing amount, high in strength, good in compactness, low in water absorption rate, good in durability and good in shrinkage resistance, effectively prevents chloride ion permeation, enables concrete to have self-healing capacity, is environmentally friendly, non-toxic, freeze-thaw-resistant, carbonization-resistant and acid-base-resistant, has no corrosion effect on steel bars, remarkably improves impermeability and reduces shrinkage.
本发明属于建筑材料添加剂技术领域，具体涉及一种混凝土防水密实剂及其制备方法，本发明所述的混凝土防水密实剂，以重量百分比计，其原料组成为：氢氧化钠10％‑20％；硫化钠8％‑12％；硫代硫酸钠2％‑5％；硫磺3％‑5％；甘油1.5％‑2.5％；油酸三乙醇胺酯1％‑1.5％；丙三醇1.5％～3％；其余为水。本发明所述的混凝土防水密实剂掺量低，强度高、密实性好、吸水率低、耐久性好、抗收缩性能好、有效防止氯离子渗透、使混凝土有自愈合能力、环保无毒、抗冻融、抗碳化、耐酸碱、对钢筋无锈蚀作用，显著提高抗渗性和减少收缩。
