Capillary crystalline backwater coating and preparation method thereof
The invention relates to a capillary crystalline backwater coating and a preparation method thereof. The coating comprises the following raw materials in parts by weight: 420-440 parts of Portland cement, 390-410 parts of quartz sand, 70-90 parts of quartz powder, 50-70 parts of latex powder, 8-12 parts of sodium silicate, 8-12 parts of borax, 1.5-2.5 parts of a powder defoaming agent, 1.5-2.5 parts of hydroxypropyl methyl cellulose, 4-4.5 parts of polyvinyl alcohol, 0.8-1.2 parts of a water reducing agent and 0.6-1 part of hydrophobic powder. The capillary crystalline type backwater coating is excellent in mortar impermeability and concrete impermeability, and particularly high in backwater pressure secondary impermeability; the preparation method only needs to uniformly stir and mix theraw materials, the process is simple and easy to control, and large-scale production is facilitated.
本发明涉及一种渗透结晶型背水涂料及其制备方法。所述渗透结晶型背水涂料，包括如下重量份的原料：硅酸盐水泥420～440份、石英砂390～410份、石英粉70～90份、乳胶粉50～70份、硅酸钠8～12份、硼砂8～12份、粉末消泡剂1.5～2.5份、羟丙基甲基纤维素1.5～2.5份、聚乙烯醇4～4.5份、减水剂0.8～1.2份和憎水粉0.6～1份。所述渗透结晶型背水涂料的砂浆抗渗性能和混凝土抗渗性能优异，尤其背水压二次抗渗能力强；所述制备方法仅需将原料均匀搅拌混合即可，工艺简单易控，有利于规模化产出。
