Problems solved by technology

At present, most of the market adopts thick film treatment, and the coating should be 30-50 microns or even more than 100 microns. However, the research and development of anti-corrosion materials with thin coatings less than 10 microns is still in its infancy.

Embodiment 1

[0023] Example 1 : Add 20g of polyvinyl butyral into 280ml of ethanol, stir until completely dissolved. Add 50ml of butanol and stir until the solution is evenly mixed. Continue to add 0.5ml KH550 to the solution and stir until it is evenly mixed. Add 2g of benzoimidazole to the solution, stir until completely dissolved, and brush the solution directly on the surface polished with fine sandpaper, clean it with acetone and paint it on a dry copper plate or steel, and dry it at room temperature for 4 hours to obtain a thickness of 2 ~4 micron coating. The coating hardness is 2H, the adhesion is grade 1, and the salt spray resistance test reaches more than 80 hours.

Embodiment 2

[0024] Example 2 : Add 25g of polyvinyl butyral into 280ml of ethanol, stir until completely dissolved. Add 40ml of butanol and stir until the solution is evenly mixed. Continue to add 0.4ml KH550 to the solution and stir until it is evenly mixed. Add 4 g of benzotriazole to this solution and stir until completely dissolved. The obtained solution is brushed or sprayed on the fine sandpaper, washed with acetone and painted on the dry copper plate or steel, and dried at room temperature for 3 hours to obtain a coating with a thickness of 4-7 microns. The coating hardness is 2H, the adhesion is grade 1, and the salt spray test can reach 120 hours.

Embodiment 3

[0025] Example 3 : Add 20g of polyvinyl butyral into 280ml of ethanol, stir until completely dissolved. Add 40ml of butanol and stir until the solution is evenly mixed. Add 0.4ml KH550 and 4g benzotriazole to the solution, stir until completely dissolved. Continue to add 4 g of ground powdered sodium molybdate and stir until it is evenly dispersed. The obtained solution is brushed and polished with fine sandpaper, cleaned with acetone and painted on a dry copper plate or steel, and dried at room temperature for 3 hours to obtain a coating with a thickness of 4-6 microns. The coating hardness is 2H, the adhesion is grade 1, and the salt spray test can reach 150 hours.

Abstract

The invention discloses a static electricity resistant anticorrosive paint and a preparation method thereof. The paint is prepared form the following steps: dissolving polyvinyl butyral in ethanol with stirring to obtain a 5-25wt% polyvinyl butyral solution; adding auxiliaries being 5-28wt% of the polyvinyl butyral into the solution and stirring for 50-80 min; adding corrosion inhibitor being 2-8wt% of the polyvinyl butyral into the prepared solution and stirring to complete dissolve; adding molybdate or iodide being 2-6wt% of the polyvinyl butyral into the prepared solution with stirring and stirring for 50-80 min. The environment-friendly paint of the invention can be applied to non-ferrous metal surface treatment, has good protective and anticorrosive effects and can keep original metal luster; a surface drying speed is fast with a time of 13-18 min; the coating has flattening and light appearance, good adhesion, high hardness, good salt spray resistance and antistatic effect.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, in particular to a static-resistant anti-corrosion coating and a preparation method thereof. [0002] Background technique [0003] At present, most of the metal anti-corrosion materials commonly used contain benzene series such as benzene, toluene, chloroform, etc., which have caused great harm to the environment and human body during construction and use. Polyvinyl butyral has high transparency, good light resistance, water resistance, film forming and impact resistance, and is non-toxic, odorless and non-corrosive, especially in glass, plexiglass, metal, wood, Ceramics, leather, fibers and other materials have good adhesion properties, and can be used as coatings, inks, adhesives, etc. However, the composition of the coating made of polyvinyl butyral is complex, and only when the thickness of the coating is thicker can it have a better anti-corrosion effect, and the coating h...
