Problems solved by technology

At the same time, most of the water-based metal rust inhibitors in the early stage were nitrite or chromate aqueous solutions. As we all know, nitrites are carcinogens, which are harmful to the health of operators. Heavy metals are harmful to the environment, and heavy metals are introduced into the workpiece during processing, which affects the performance and quality of the workpiece

Abstract

An anticorrosive coating of a steel structure is prepared from, by weight, 15-17 parts of silicon dioxide, 1-1.5 parts of titanium oxide, 6-9 parts of aluminum oxide, 20-25 parts of manganese oxide, 7-9 parts of ferrous oxide, 4-5 parts of magnesium oxide, 3-5 parts of calcium oxide, 30-40 parts of butyl acrylate, 10-15 parts of triethylene tetramine, 28-35 parts of liquid epoxy resin, 5-7 parts of 2-amino-2-methyl-1-propyl alcohol and 3-5 parts of polyether polyol diglycidyl ether. The anticorrosive coating has the quite good anticorrosive effect on the steel structure.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anticorrosion coating for steel structures. Background technique [0002] At present, with the continuous development of industry, the use of steel is also increasing. However, during the production process or the storage process of finished products, steel plates are easily oxidized and rusted when encountering humid air and rainy days, which affects the appearance quality of products. This has brought problems to the use of steel. The annual loss of steel due to corrosion is very alarming. In order to prevent surface corrosion, antirust treatment must be carried out; Protective oil film, so as to isolate the corrosion of metal by water vapor in the air, and achieve the purpose of rust prevention. However, the use of antirust oil requires a large amount of oil raw materials, which intensifies energy consumption and increases costs. Therefore, it is only used in a s...
