Mortar waterproof agent, preparation method thereof and super-hydrophobic mortar
The invention provides a mortar waterproof agent, a preparation method thereof and super-hydrophobic mortar, and belongs to the technical field of concrete materials. The mortar waterproof agent provided by the invention is prepared from the following raw materials in parts by mass: 45-60 parts of organosilane, 45-60 parts of a solvent, 1-3 parts of a pH regulator, 6-8 parts of a surfactant, 100-120 parts of water and 50-100 parts of silicon dioxide. The mortar waterproof agent provided by the invention is applied to mortar, after the mortar waterproof agent is cured for 28 days, the contact angle is 153.8 degrees, the corrosion potential is-0.368 V, the corrosion current density is 3.878 * 10 <-6 > A.cm <-2 >, liquid in a dropper is dropped on a layer of pollutants uniformly coated on one side of the super-hydrophobic mortar, and the liquid drops easily roll down from the surface of the super-hydrophobic mortar by rotating 15-20 degrees from the horizontal direction, so that the super-hydrophobic mortar has a good waterproof effect. Pollutants are taken away, obvious sliding marks are left, and the paint has excellent waterproofness and good corrosion resistance and self-cleaning performance.
本发明提供了一种砂浆防水剂及其制备方法和超疏水砂浆，属于混凝土材料技术领域。本发明提供的砂浆防水剂，由包括以下质量份数的原料制备得到：有机硅烷45～60份、溶剂45～60份、pH调节剂1～3份、表面活性剂6～8份、水100～120份和二氧化硅50～100份。本发明提供的砂浆防水剂应用到砂浆中，固化28天后接触角为153.8°，腐蚀电位为‑0.368V，腐蚀电流密度为3.878×10‑6A·cm‑2，将滴管中的液体滴于超疏水砂浆的一侧均匀涂覆的一层污染物上，并从水平方向旋转15～20°，液滴很容易从超疏水砂浆表面滚下来，带走污染物，并留下了明显的滑痕，具有优异防水性、良好的抗腐蚀及自清洁性。
