Abstract

The invention discloses a preparation and application method of a rust-transforming and rust-removing agent for steel structures, which belong to the technical field of metal surface cleaning treatment. The rust-removing and rust-removing agent comprises the following components: hydrochloric acid, sulfamic acid, sodium chlorate, disodium edetate, gallic acid, propylene glycol alginate, acid mist inhibitor, and deionized water. Its use method includes the following steps: add the above-mentioned components into the reaction tank in sequence, mix and stir for about 50 minutes at a temperature of 40-60°C, cool and filter to obtain a rust-reversing and anti-rust paint for steel structures; remove construction steel For oil stains, mud sand and dust on the surface of the structure, apply the anti-rust paint directly on the steel surface of the steel structure; put the coated steel in the air for 1-2 hours, and then carry out the paint construction. The rust-transforming and anti-rust coating agent has the advantages of being used at normal temperature, non-toxic, phosphorus-free, thorough rust removal, high strength, good adhesion, energy saving and environmental protection, and the like.

Description

technical field [0001] The invention relates to the preparation and application method of a rust-removing rust-removing agent for steel structures, and belongs to the technical field of metal surface cleaning treatment. Background technique [0002] Steel is the most commonly used structural material with unstable thermodynamic properties, and it will inevitably corrode and transform into loose rust when exposed to the atmosphere. Various metal components and equipment in my country, the annual loss due to corrosion is as high as 10-15 billion yuan. It can be seen that metal corrosion will have a serious impact on the national economy and enterprise development. At the same time, metal corrosion also endangers personal safety and causes environmental pollution. [0003] One of the key factors for the quality of steel structure paint coating is rust removal and rust prevention. Rust removal before paint coating is a hidden project of steel structure construction. Thorough rus...
