Abstract

The invention discloses a steel structural rust conversion anti-rust paint used in building. The formulation is that rust conversion agent of polyatomic acid is 300-700 parts, gelling agent is 20-40 parts, atmospheric inhibitor is 1-2 parts, penetrating agent is 0.5-1 parts, organic silicon defoaming agent is 0.1-0.5 parts, and water is 256-678 parts. The steps of usage of the invention include that the components are sequentially added in a reaction tank, mixed and stirred for about 50 minutes under the temperature of 40-60 DEG C, and cooled and filtered to prepare the steel structural rust conversion anti-rust paint. The steel structural rust conversion anti-rust paint is directly brushed on the surface of steel products to remove greasy dirt, mud and sand, and dust which are on the surface of constructional steel structure. The steel products which are coated with the rust conversion anti-rust paint are placed in the air for 1-2 hours, and then are processed via oil paint construction. The rust conversion anti-rust paint has the advantages of thorough rust conversion, simple construction, economy and efficiency, energy-saving, environmental protection and the like, and is capable of strengthening the anti-rust and anti-fire property of the oil paint and increasing the inherent quality of the oil paint.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a rust-transferring and anti-rust coating agent for derusting and anti-corrosion of building steel structure materials and a use method thereof. 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. The loss of various metal components and equipment in our country due to corrosion is as high as 10-15 billion yuan every year. In the engineering technology of coating and anticorrosion for the purpose of protecting the surface of building steel structures from corrosion, derusting is a very important and indispensable process step. [0003] There are two technical keys in the use of steel structure buildings: one is anti-rust and the other is fire prevention. This needs to be solved through the painting (painting) process...
