Anti-carbonization coating with super-strong adaptability and preparation method thereof
The invention discloses an anti-carbonization coating with super-strong adaptability and a preparation method thereof, and relates to the technical field of concrete. The coating comprises a permeableprimer, a middle-layer paint and a finish paint, and the permeable primer comprises a lithium silicate aqueous solution, a special permeable emulsion, deionized water, a coalescing agent, a defoamingagent and diamond jade in percentage by weight; the middle-layer paint comprises a group A and a group B, wherein the group A comprises a water-based hyperbranched emulsion, a special auxiliary agent, a mildew preventive and a tungsten-doped nano vanadium dioxide dispersion liquid; and the group B comprises special cement, quartz sand, talcum powder and a powdery defoaming agent; and the finish paint comprises a water-based hyperbranched modified silicone acrylic emulsion, a mildew preventive, a coalescing agent, deionized water, a defoaming agent, a wetting agent and a thickening agent. Thecoating can effectively prevent water from reacting with repaired concrete, can generate good adherence with middle-layer paint, can quickly extrude water to the surface, is not influenced by environmental humidity, has good ageing resistance, further protects the concrete and reduces the carbonization opportunity.
本发明公开了一种具备超强适应性的防碳化涂料及其制备方法，涉及混泥土技术领域。本发明包括渗透底漆、中层漆、面漆组成，按照重量百分比，渗透底漆包括：硅酸锂水溶液、特种渗透乳液、去离子水、成膜助剂、消泡剂、金刚玉；中层漆包括A组:水性超支化乳液、特种助剂、防霉剂、钨掺杂纳米二氧化钒分散液；B组:特种水泥、石英砂、滑石粉、粉状消泡剂；面漆包括:水性超支化改性硅丙乳液、防霉剂、成膜助剂、去离子水、消泡剂、润湿剂、增稠剂。本发明能够有效阻止水与修补的混泥土产生反应，并且能够与中层漆产生良好的密着性，能够快速把水分挤压到表面，不受环境湿度影响，具有良好的耐老化性能，并且进一步保护混泥土减少碳化的机会。
