Anticorrosive paint coating method

Abstract

The invention discloses a coating method of an anticorrosive paint. The coating method comprises the following steps: pretreating the surface of a substrate; the method comprises the following steps: extracting bituminous coal to obtain an extract and a raffinate; preparing a prime paint by using the extract as a film-forming reinforcing agent of the prime paint, and preparing a surface paint by using the raffinate as an organic flame retardant. The raw materials of the surface layer coating and the bottom layer coating are respectively obtained through the separation treatment of the bituminous coal, and then are used for film formation and connection reinforcement, so that the utilization rate of the bituminous coal is improved, and the high-value application of the bituminous coal is realized on the premise of not carrying out fine separation.

Description

technical field [0001] The present application relates to a method for coating an anti-corrosion paint. Background technique [0002] The existing anti-corrosion coatings are generally set up as coatings. The advantage of single-layer coatings is that the coating effect is good and it is not easy to separate. The disadvantage is that it is difficult to balance between anti-corrosion and heat insulation. Generally, one function is preferred. A function can only be weakened. There are also some setting methods of double-layer anti-corrosion coatings, but due to the problem of poor compatibility between the two coatings, there may be disadvantages such as detachment and poor adhesion during use. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned problems, the present application proposes a method for coating an anti-corrosion paint, comprising the following steps: [0004] Pretreatment of the substrate surface; [0005] Extracting bituminous coal to ob...

[0002] Existing anti-corrosion coatings are generally used as coatings. The advantages of single-layer coatings are good coating effect and not easy to detach. The disadvantage is that it is difficult to achieve a balance between anti-corrosion and heat insulation. Generally, one function is preferred. A function can only be weakened

There are also some double-layer anti-corrosion coatings, but due to the poor compatibility between the two coatings, there may be disadvantages such as detachment during use and poor adhesion performance.
