The invention discloses a building waterproof agent and a preparation method thereof. The waterproof agent is prepared from the following components: triethanolamine, sodium chloride, sodium nitrite, silicate, silicon dioxide and a composite expansion material in proportion, wherein the weight ratio of triethanolamine to sodium chloride to sodium nitrite is 1: 6: 12. The alunite and the gypsum are prepared into the composite expansion material in proportion, and the weight ratio of the alunite to the gypsum is 1: (1-2). According to the waterproof agent, triethanolamine, sodium chloride and sodium nitrite are doped to enhance the impermeability of the waterproof agent when the waterproof agent is applied to cement, based on the synergistic cooperation of triethanolamine, sodium chloride and sodium nitrite, the compactness of concrete poured by the cement is enhanced by generating a complex and reducing free water, and the strength and the impermeability are improved; besides, the alunite and the gypsum are mixed in proportion to form the composite expansion material, so that the probability of generating shrinkage cracks is reduced, and the waterproof strength and the application safety are guaranteed.
本发明公开了一种建筑用防水剂及其制备方法。上述防水剂具备如下组分：三乙醇胺、氯化钠、亚硝酸钠、硅酸盐、二氧化硅和复合膨胀材料按比例制作得到防水剂。其中，三乙醇胺、氯化钠和亚硝酸钠的重量份配比为1：6：12。明矾石和石膏按比例制作得到复合膨胀材料，其中，明矾石和石膏的重量份配比为1：1~2。本发明的防水剂，掺入三乙醇胺、氯化钠和亚硝酸钠来增强防水剂应用在水泥中时的抗渗性，基于三乙醇胺、氯化钠和亚硝酸钠的协同配合，通过产生络合物和减少游离水来增强水泥浇灌成混凝土的密实性、提高强度和抗渗性，并且，掺入明矾石和石膏按比例混配的复合膨胀材料来减少产生收缩裂缝的概率，保障防水力度和应用的安全性。
