High-permeability concrete protective coating and preparation method thereof
The invention provides a high-permeability concrete protective coating and a preparation method thereof. Raw materials for preparing the concrete protective coating comprise a powder material and a liquid material, the powder material comprises the following components in parts by mass: 40-60 parts of Portland cement, 2-4 parts of nano silicon dioxide, 30-40 parts of quartz sand and 8-12 parts of silicate; the liquid material is prepared from the following components in parts by mass: 15 to 20 parts of siloxane oligomer, 20 to 30 parts of acrylate emulsion and 4 to 6 parts of sustained-release capsule; the sustained-release capsule takes graphene oxide as a capsule wall and silicone zirconium as a capsule core. According to the invention, the siloxane oligomer is introduced to replace a traditional volatile and non-environment-friendly solvent, and is matched with the nano silicon dioxide and the silicate to be subjected to hydration reaction with the concrete to fill micropores of mortar, so that the compactness and the impermeability of the concrete are synergistically enhanced, and the permeability of the coating is improved. And the sustained-release capsule is introduced, so that the compression resistance of the concrete can be enhanced, and the service life of the concrete is prolonged.
本发明提供一种高渗透的混凝土防护涂料及其制备方法，制备该混凝土防护涂料的原料包括粉料、液料；按照质量份数计算，粉料包括40～60份硅酸盐水泥、2～4份纳米二氧化硅、30～40份石英砂、8～12份硅酸盐；按照质量份数计算，液料包括15～20份硅氧烷低聚物、20～30份丙烯酸酯乳液、4～6份缓释胶囊；缓释胶囊以氧化石墨烯作为囊壁，硅酮锆作为囊芯。在本发明当中，通过引入硅氧烷低聚物替代传统易挥发性、非环保性溶剂，并搭配纳米二氧化硅、硅酸盐，与混凝土发生水化反应填充胶砂的微孔隙，协同增强混凝土的密实度和抗渗性能，并提高涂料的渗透性能。而引入缓释胶囊则能增强混凝土的抗压性能，延长混凝土的使用寿命。
