Abstract

The invention discloses an anti-corrosion treatment agent for a rust removal avoidance metal surface. The anti-corrosion treatment agent is prepared from a rust removal solution and Portland cement according to the weight ratio of 1:(1.2 to 1.5); the rust removal solution is prepared from the following raw materials in percentage by weight: 2 to 4 percent of polyvinyl alcohol, 4 to 6 percent of calcium chloride, 1 to 3 percent of dispersion composite auxiliary agents and 87 to 93 percent of water. The ingredients are simple; the cost is low; the realization is easy; rust removal ingredients are contained, so that rust removal and grinding are not needed by the metal surface during the construction; the anti-corrosion treatment agent for a rust removal avoidance metal surface can be applied to various metal surface treatment agents, so that the treatment agent can be directly coated onto the metal surface, and is applicable to the protection on iron frames, dams and metal embedding elements.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a rust-free metal surface anticorrosion treatment agent. Background technique [0002] Steel structures such as steel-frame buildings or steel-frame bridges are premised on long-term use. Therefore, these steel structures have been given surface coating for the purpose of ensuring corrosion resistance and aesthetics. Generally, the coating consists of a base coat for rust resistance, a top coat for ensuring weather resistance and aesthetics, and an intermediate coat for improving the adhesion between the base coat and the top coat. The coating consists of three layers. The coating life is greatly affected by the coating material and the use environment, but in a more severe environment, there are also modified epoxy-based coatings with a coating life of 6 years, and epoxy-urethane-based coatings with a coating life of 6 years. For 10 years such an example. Consequently,...
