Waterproof acid-resistant concrete and preparation method thereof
The invention relates to waterproof acid-resistant concrete and a preparation method thereof. The waterproof acid-resistant concrete is composed of cement, sand, water, waterproof resin, acrylate resin and calcium sulfate whiskers, wherein the waterproof resin is prepared from acrylic acid, fumed silica, butyl acrylate, methyl methacrylate, ammonium persulfate, an SE-10 emulsifier, water and methoxy polyethylene glycol 550 monoacrylate through a reaction; the acrylate resin is prepared from acrylic acid, powdered nitrile rubber, methacrylic acid, butyl acrylate, water, an SE-10 emulsifier, ammonium persulfate and polyvinyl alcohol through a reaction; and the calcium sulfate whiskers are prepared from an aqueous sodium sulfate solution, saturated calcium hydroxide and acetic acid through a reaction. The impact-resistant concrete provided by the invention has excellent water resistance and acid corrosion resistance.
本发明涉及一种防水耐酸型混凝土及其制备方法。所述防水耐酸型混凝土由水泥、砂子、水、防水树脂、丙烯酸酯树脂和硫酸钙晶须组成，所述防水树脂由丙烯酸、气相二氧化硅、丙烯酸丁酯、甲基丙烯酸甲酯、过硫酸铵、SE‑10乳化剂、水和甲氧基聚乙二醇550单丙烯酸酯反应制得，所述丙烯酸酯树脂由丙烯酸、粉末丁腈橡胶、甲基丙烯酸、丙烯酸丁酯、水、SE‑10乳化剂、过硫酸铵和聚乙烯醇反应制得，所述硫酸钙晶须由硫酸钠水溶液、饱和氢氧化钙和乙酸反应制得。本发明提供的抗冲击混凝土具有优异的防水和抗酸腐蚀性能。
