Long-acting inorganic protective coating as well as preparation method and application thereof
The invention relates to the technical field of concrete road and bridge engineering protection, and particularly discloses a long-acting inorganic protective coating as well as a preparation method and application thereof. The long-acting inorganic protective coating is prepared from the following components in percentage by mass: 5 to 15 percent of silane hybrid modified nano potassium silicate solution, 10 to 25 percent of silane hybrid modified nano silica sol, 5 to 8 percent of styrene-acrylic emulsion, 20 to 30 percent of body filler, 10 to 20 percent of high titanium powder, 0.5 to 5 percent of inorganic color paste, 1 to 5 percent of water repellent, 1 to 5 percent of additive and the balance of first deionized water. The silane modified potassium silicate solution and the silica sol are added, active silicon hydroxyl parts contained in the silane modified potassium silicate solution and the silica sol can be chemically bonded with silicon hydroxyl and calcium ions in concrete, and the adhesive force between the coating and the concrete is remarkably improved; after the coating is dried, a net-shaped semi-permeable coating film is formed on the surface of the concrete and is waterproof and breathable, and the service life of the concrete is prolonged.
本发明涉及混凝土路桥工程防护技术领域，具体公开一种长效无机防护涂料及其制备方法和应用。所述长效无机防护涂料，按照质量百分比计，包括如下各组分：硅烷杂化改性纳米硅酸钾溶液：5％～15％，硅烷杂化改性纳米硅溶胶：10％～25％，苯丙乳液：5％～8％，体质填料：20％～30％，高钛粉：10％～20％，无机色浆：0.5％～5％，憎水剂：1％～5％，助剂：1％～5％，余量为第一去离子水。本申请通过添加硅烷改性的硅酸钾溶液和硅溶胶，其含有的活性硅羟基部分能够与混凝土中的硅羟基、钙离子生产化学键合，显著提高涂层与混凝土之间的附着力；涂层干燥后在混凝土表面形成网状半透性涂膜，防水透气，提高混凝土的使用寿命。
