Super-hydrophobic microcapsule polymer cement-based anticorrosive coating as well as preparation method and application thereof
The invention relates to the field of cement anticorrosive coatings, in particular to a super-hydrophobic microcapsule polymer cement-based anticorrosive coating as well as a preparation method and application thereof. The coating is prepared from the following raw materials in parts by weight: 65-85 parts of cement, 65-70 parts of quartz sand, 0.5-1.0 part of a reinforcing agent, 0.17-0.32 part of a retarder, 45-55 parts of emulsion, 15-18 parts of water, 1.1-1.8 parts of a coalescing agent, 0.47-1.4 parts of a light stabilizer, 0.2-0.6 part of a preservative, 0.05-0.3 part of hydrophobic modified graphene oxide and 6-8 parts of a water-based microcapsule emulsion, wherein the water-based microcapsule emulsion is of a core-shell structure formed by taking a hydrophobic material as a coreand SiO2 gel as a shell layer. The anticorrosive paint provided by the invention avoids adverse effects on a cement hydration hardening process and a polymer film forming process, and effectively solves the problem of compatibility between a hydrophobic agent and emulsion as well as between the hydrophobic agent and cement.
本发明涉及水泥防腐涂料领域，具体涉及一种超疏水微胶囊聚合物水泥基防腐涂料及其制备方法与应用。以重量份计，所述涂料的原料包括如下组分：65‑85份水泥，65‑70份石英砂，0.5‑1.0份增强剂，0.17‑0.32份缓凝剂，45‑55份乳液，15‑18份水，1.1‑1.8份成膜助剂，0.47‑1.4份光稳定剂，0.2‑0.6份防腐剂，0.05‑0.3份疏水改性氧化石墨烯，6‑8份水性微胶囊乳液、且该水性微胶囊乳液是以疏水材料为核、以SiO2凝胶为壳层形成的核壳结构。本发明的这种防腐涂料避免了对水泥水化硬化过程以及聚合物成膜过程中的不利影响，而且有效解决了疏水剂与乳液和水泥的相容性问题。
