Heat-insulating anticorrosive coating for concrete surface and preparation method thereof
The invention discloses a heat-insulating anticorrosive coating for a concrete surface. The heat-insulating anticorrosive coating comprises the following components in parts by weight: 100 to 200 parts of a phosphate adhesive, 150 to 200 parts of metal hydroxide, 120 to 200 parts of deionized water, 20 to 40 parts of calcium oxide, 10 to 30 parts of heat-insulating particles, 50 to 100 parts of nanometer aluminum oxide, 10 to 20 parts of a dispersing agent and 10 to 50 parts of a retarder. The invention further discloses a preparation method of the heat-insulating anticorrosive coating for theconcrete surface. The heat-insulating anticorrosive coating for the concrete surface provided by the invention can be cured at normal temperature to form a film, so high-temperature firing on the concrete surface is eliminated; phosphate has high temperature resistance; and the calcium oxide compound compatible with concrete is added, so the problem of insufficient cohesiveness between the phosphate adhesive and the concrete is solved.
本发明公开了一种混凝土表面隔热防腐涂层，包括以下按重量计的原料成分：磷酸盐胶粘剂100‑200份，金属氢氧化物150‑200份，去等离子水120‑200份，钙氧化合物20‑40份，隔热颗粒10‑30份，纳米氧化铝50‑100份，分散剂10‑20份，缓凝剂10‑50份。本发明还公开了一种混凝土表面隔热防腐涂层的制备方法。本发明提供的混凝土表面隔热防腐涂层不仅可以常温固化成膜，消除在混凝土表面高温烧制，而且磷酸盐本身具有耐高温性，同时添加与混凝土相容的钙氧化合物，解决了磷酸盐胶粘剂与混凝土粘结性不足的问题。
