Anti-corrosion and reinforcing coating applied to reinforcing steel bars in concrete
The invention discloses an anti-corrosion and reinforcing coating applied to reinforcing steel bars in concrete, which comprises a polymer emulsion and a powder material in a weight ratio of 1: 2.0, the macromolecular emulsion is prepared from the following raw materials in parts by weight: rust conversion emulsion, waterborne epoxy resin, polytrifluorochloroethylene resin, polysiloxane, organic silicon resin, vinyl versatate, a flatting agent, a catalyst, a defoaming agent and a dispersing agent, and the powder is prepared from the following raw materials in parts by weight: ceramic micro powder, spherical graphite powder, glass flakes, mica flakes and pigment. Compared with the prior art, the interface coating has the advantages that the interface coating for repairing can improve the corrosion resistance and rust resistance of reinforcing steel bars, improve the binding force between the reinforcing steel bars and repairing cement mortar and improve the bond-wrapping effect of the cement mortar on the reinforcing steel bars, and can also be applied to tunnels and directly coat steel members in a humid environment; therefore, the device can be popularized and applied in reinforcement and maintenance engineering.
本发明公开了一种应用于混凝土中钢筋的防腐及加固涂料，包括高分子乳液和粉料，所述高分子乳液和粉料的重量比为1：2.0，所述高分子乳液由以下原料组成：转锈乳液、水性环氧树脂、聚三氟氯乙烯树脂、聚硅氧烷、有机硅树脂、叔碳酸乙烯酯、流平剂、催化剂、消泡剂、分散剂，所述粉料由以下重量份原料组成：陶瓷微粉、球状石墨粉、玻璃鳞片、云母鳞片、颜料，本发明与现有技术相比的优点在于：本发明作为修补用界面涂料，可以提高钢筋的防腐防锈能力，提高钢筋与修补水泥砂浆之间的粘结力，提高水泥沙浆对钢筋的握裹作用，也可以应用在隧道里，对潮湿环境下的钢构件直接涂覆，起到很好的保护作用，在加固维护工程中可以推广应用。
