Mining cement-based waterproof coating and preparation method thereof
The invention relates to the technical field of waterproof coatings, and particularly discloses a mining cement-based waterproof coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 35 to 50 parts of Portland cement, 15 to 25 parts of quartz sand, 10 to 15 parts of ettringite, 10 to 20 parts of organic silicon-acrylate copolymer, 10 to 20 parts of acrylic emulsion, 0.5 to 0.8 part of organic silicon defoaming agent, 0.3 to 0.5 part of penetrating agent, 0.5 to 1 part of thickening agent, 4 to 6 parts of nonionic surfactant and 20 to 30 parts of deionized water. The ettringite, the Portland cement and the organic silicon-acrylate copolymer act together, a capillary crystallization effect can be generated in the concrete, capillary pores and microcracks are filled, and the compactness and impermeability of the concrete are improved; the synergistic use of the organosilicon-acrylate copolymer and the acrylic emulsion can better adapt to the deformation of the base layer, reduce the cracking and falling problems caused by the deformation of the base layer, and improve the waterproof effect.
本发明涉防水涂料技术领域，具体公开了矿用水泥基防水涂料及其制备方法，所述涂料按重量份计包括以下原料：硅酸盐水泥35～50份、石英砂15～25份、钙矾石10～15份、有机硅‑丙烯酸酯共聚物10～20份、丙烯酸乳液10～20份、有机硅消泡剂0.5～0.8份、渗透剂0.3～0.5份、增稠剂0.5～1份、非离子型表面活性剂4～6份、去离子水20～30份；在本发明中钙矾石、硅酸盐水泥与有机硅‑丙烯酸酯共聚物共同作用，能够在混凝土内部产生渗透结晶效应，填充毛细孔和微裂缝，提高混凝土的密实性和抗渗性；有机硅‑丙烯酸酯共聚物和丙烯酸乳液的协同使用能够更好地适应基层的变形，减少因基层变形而导致的开裂和脱落问题，提高防水效果。
