Capillary crystalline cement-based waterproof coating and preparation method thereof
The invention relates to the technical field of waterproof coatings and preparation methods, in particular to a capillary crystalline cement-based waterproof coating which comprises the following components in parts by weight: 3-8 parts of medical stone composite super water-absorbent resin, 5-10 parts of a crystallization activator, 30-50 parts of Portland cement, 15-30 parts of quartz sand and 10-25 parts of inorganic filler. The preparation method comprises the step of uniformly grinding and dispersing the raw materials. According to the invention, the problems of low compactness and poor waterproof performance of concrete caused by the cement-based crystalline waterproof coating in the prior art are solved. According to the permeable crystallization type cement-based waterproof coating, the medical stone composite water-absorbent resin is added, so that the water-retaining property of the coating can be improved, and cement hydration and sustainable permeation of the crystallization activator can be ensured. After construction, the medical stone composite water-absorbent resin is subjected to a water retention-water release process, it is ensured that the crystallization activator continuously permeates into capillary pores of concrete after being hydrated and reacts and crystallizes in the capillary pores of the concrete to block the capillary pores, so that the compactness of the concrete is improved, and the waterproof performance of the concrete is improved.
本发明涉及防水涂料及制备方法技术领域，特别是涉及一种渗透结晶型水泥基防水涂料，包括：3~8份的麦饭石复合高吸水树脂，5~10份的结晶活化剂，30~50份的硅酸盐水泥，15~30份的石英砂，10~25份的无机填料。制备方法为：将原料研磨分散均匀，即得。本发明解决现有技术中水泥基结晶型防水涂料导致混凝土致密性低防水性能差的问题。上述渗透结晶型水泥基防水涂料加入麦饭石复合吸水树脂可增加涂料的保水性，从而能确保水泥水化及结晶活化剂可持续渗透。施工后麦饭石复合吸水树脂经过保水‑释水过程保证了结晶活化剂水化后，持续向混凝土毛细孔中渗透，并在混凝土毛细孔中反应结晶，堵塞毛细孔，提高了混凝土的致密性，从而提高混凝土的防水性能。
