Acid-resistant concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses acid-resistant concrete and a preparation method thereof. The acid-resistant concrete is prepared from the following raw materials in parts by weight: 5 to 8 parts of water glass, 2 to 4 parts of modified liquid polysulfide rubber, 1 to 3 parts of epoxy resin, 5 to 8 parts of filler, 10 to 15 parts of cement, 10 to 15 parts of water, 2.5 to 3.5 parts of water reducing agent, 0.05 to 0.08 part of ethylenediamine and 0.15 to 0.3 part of isobutanol, wherein the modified liquid polysulfide rubber is polysulfide rubber subjected to hydrophobic modification by silicon dioxide aerogel; the preparation method comprises the following steps: uniformly mixing the filler, the cement, the water glass, the water reducing agent and the water, preheating to 50-60 DEG C, adding the modified polysulfide rubber, the epoxy resin, the ethylenediamine and the isobutanol, continuously heating to 140-150 DEG C, uniformly mixing, pouring into a mold, and curing to obtain the acid-resistant concrete. The composition disclosed by the invention can be used for various places needing to be in contact with acidic substances, and has the advantages of good impermeability and good acid resistance.
本申请涉及建筑材料领域，具体公开了一种耐酸混凝土及其制备方法。一种耐酸混凝土包括如下重量份原料：水玻璃5‑8份、改性液态聚硫橡胶2‑4份、环氧树脂1‑3份、填料5‑8份、水泥10‑15份、水10‑15份、减水剂2.5‑3.5份、乙二胺0.05‑0.08份、异丁醇0.15‑0.3份，所述改性液态聚硫橡胶为经过二氧化硅气凝胶疏水改性的聚硫橡胶；其制备方法为：将填料、水泥、水玻璃、减水剂以及水混合均匀后预热至50‑60℃，加入改性聚硫橡胶、环氧树脂、乙二胺、异丁醇继续加热至140‑150℃，混合均匀，倒入模具中固化制得所述耐酸混凝土。本申请的组合物可用于各种需要接触酸性物质的场所，其具有抗渗性好、耐酸性好的优点。
