Problems solved by technology

Moreover, rust can hardly be completely removed during repainting and maintenance.
Rust surface anti-corrosion coatings are developed to meet this situation; rust surface anti-corrosion coatings are a new type of coating that can be directly painted on steel surfaces with residual rust. There are many varieties, which can be roughly divided into three types. That is, penetration type, conversion type and stable type; however, the existing rust surface anticorrosion coating has a single mechanism of action, and the antirust effect is not ideal

Embodiment Construction

[0026] The anticorrosion paint with rust coating is characterized in that: its composition is (weight ratio):

[0027] Linoleic acid 42.0;

[0028] Anionic surfactant 0.5;

[0029] Anti-skinning agent 1.0;

[0030] Mix Cui dry agent (lead, cobalt, manganese) 3.0;

[0031] Iron oxide red 15.0;

[0032] Zinc oxide (50% lead) 7.5;

[0033] Tetrabasic Zinc Yellow 3.0;

[0034] Strontium chromate 3.0;

[0035] Zinc phosphate 1.5;

[0036] Diphenylguanidine chromate 2.6;

Abstract

The anticorrosive paint for painting on rusty surface consists of tong oil alcohol acid 40.0í½50.0 weight portions, anionic surfactant 0.4í½1.0 weight portions, anti-skimming agent 0.5í½2.0 weight portions, mixed drier 2.0í½5.0 weight portions, iron oxide red 10.0í½20.0 weight portions, zinc oxide 5.0í½10.0 weight portions, zinc tetrahydroxy yellow 2.0í½5.0 weight portions, strontium chromate 2.0í½5.0 weight portions, zinc phosphate 2.0í½3.0 weight portions, diphenyl guanidine chromate 2.0í½4.0 weight portions, toluene 15.0í½25.0 weight portions and xylene 6.0í½10.0 weight portions. The anticorrosive paint is suitable for rusty iron and steel surface, and may be painted on rusty surface to form corrosion inhibiting deactivating film to reach excellent antirust effect.

Description

technical field [0001] The invention relates to an anticorrosion coating which can be applied without derusting. Background technique [0002] When traditional coatings are applied on the steel surface, it is required to completely remove rust. This is a very heavy work, which not only consumes a lot of man-hours, but also increases costs, because the existence of rust has a great impact on the quality of the coating. It is estimated that the general construction cost is 5 times of the coating cost, and the construction cost of marine equipment can be up to 10 times. According to reports, the distribution ratio of steel plate coating costs is: surface treatment accounts for 42%, construction accounts for 30%, and paint accounts for 19%. [0003] For some large-scale projects, such as bridges, ships, offshore oil production facilities, etc., due to the long construction period, the pre-painted primer is often damaged and rusted again during the construction process. Therefor...
