Preparation method of concrete waterproof compacting agent
The invention discloses a preparation method of a concrete waterproof compacting agent. According to the invention, 15%-20% of organic silicon; 0.5%-1.5% of inorganic aluminum; 5%-8% of naphthalene sulfonate; 10%-12% of pulverized coal; 5%-8% of hydroxypropyl methyl cellulose; 10%-15% of ammonium sulfate; and the balance of water. The preparation method comprises the following steps: mixing the organic silicon, the inorganic aluminum, the naphthalene sulfonate and the pulverized coal in proportion, adding into a monomer tank, stirring at room temperature for 30 minutes, heating to 1000-1300 DEG C, stopping heating, placing the mixed raw material, cooling to 300-400 DEG C, and adding the water according to the weight ratio; cooling to 65 DEG C, waiting for 1 hour, adding the hydroxypropyl methyl cellulose and the ammonium sulfate in proportion, stirring for 20-40 minutes, and naturally reacting for 4 hours. The organic silicon, the inorganic aluminum, the naphthalene sulfonate, the pulverized coal, the propyl methyl fiber and the ammonium sulfate which are used as raw materials are easy to obtain and moderate in price, the cost of the method is relatively low, and the method has the advantages of being simple and convenient in process, easy to operate and low in cost, so that resource waste can be reduced, and the resource utilization rate is increased.
本发明公开了一种混凝土防水密实剂的制备方法。本发明有机硅15%‑20%；无机铝0.5%‑1.5%；萘磺酸盐5%‑8%；煤粉10%‑12%；羟丙基甲基纤维素5%‑8%；硫酸铵10%‑15%；其余为水；所述有机硅、无机铝、萘磺酸盐、煤粉按比例混合加入到单体罐中，室温搅拌30min，加热至1000℃‑1300℃，停止加热，将混合原料放置冷却至温度300℃‑400℃时，按照配比重量加入水；冷却至65℃后等待1h按比例后加入所述羟丙基甲基纤维素和硫酸铵，搅拌20‑40min，自然反应4小时后。本发明所使用的原料有机硅、无机铝、萘磺酸盐、煤粉、丙基甲基纤维、硫酸铵、容易获得并且价格适中，该方法的成本相对较低，并且本发明的方法流程简便，操作容易，低成本的优势可以减少资源的浪费，对资源利用率进行提升。
