Abstract
The invention discloses a preparation method of a scratch-resistant wear-resistant color coating steel plate, which comprises the following steps: (1) polishing the surface of the steel plate by using sand paper; (2) soaking the steel plate after mechanical polishing in a mixed solution of polyvinyl alcohol and glacial acetic acid, taking out and airing; (3) soaking the steel plate subjected to alkali washing in hydrochloric acid, taking out and airing; (4) putting the acid-washed steel plate into a passivation solution, and passivating under the condition that the anode voltage is 4-6V; (5) placing the passivated steel plate in a film forming solution to form a layer of oxidation film on the surface of the steel plate; (6) coating: coating the polymer coating material on the surface of the oxidized steel plate in a spraying or roller coating mode, then solidifying, cooling to room temperature, coating the antibacterial coating material, and solidifying; (7) and (4) soaking the steel plate obtained in the step (6) in distilled water. The surface of the steel plate is not easy to wear, easy to clean and not easy to pollute, and the propagation of bacteria, mould and the like can be reduced.
Description
Technical Field
The invention belongs to the technical field of steel plate production, and particularly relates to a preparation method of a scratch-resistant wear-resistant color coating steel plate.
Background
The color coated steel plate is a steel plate with an organic coating on a substrate, generally referred to as a color coated plate for short, and common substrates of the color coated steel plate are a cold-rolled substrate, a hot-galvanized substrate and an electro-galvanized substrate; commonly used coatings are polyester, silicon modified polyester, vinylidene fluoride, plastisol and the like. The color coated steel plate has the advantages of good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, high strength, lower cost and the like, is widely used in industries such as building household appliances, transportation and the like, particularly in the building industry and is mainly used as a steel knot.
Through the development history of more than twenty years, the color coated steel plate industry is greatly developed in China, the yield of the color coated steel plate is increased at the speed of 40% per year, and China becomes a world large country for producing color coated steel plates. However, the quality of the color steel products in China is at the low end, and the durability, the appearance and the functionality of the color steel products have certain gaps with the foreign similar products.
Disclosure of Invention
The invention mainly solves the technical problem of providing a preparation method of an anti-scraping wear-resistant color coating steel plate, after polishing, alkali washing, acid washing, passivation, oxidation and polymer coating treatment, the surface of the steel plate is not easy to be worn, easy to clean and not easy to be polluted, and the propagation of bacteria, mould and the like can be reduced, and in addition, the anti-bacterial effect of the steel plate can be further improved by the treatment of an anti-bacterial coating.
In order to solve the technical problems, the invention adopts a technical scheme that: a preparation method of a scratch-resistant and wear-resistant color coated steel plate comprises the following steps:
(1) polishing the surface of the steel plate by using sand paper;
(2) soaking the mechanically polished steel plate in a mixed solution of polyvinyl alcohol and glacial acetic acid for 15-20min, taking out, and air drying;
(3) soaking the alkali-washed steel plate in hydrochloric acid for 10-15min, taking out, and air drying;
(4) putting the acid-washed steel plate into a passivation solution, and passivating for 5-8min under the condition that the anode voltage is 4-6V;
(5) placing the passivated steel plate in a film forming solution, and treating the steel plate by using alternating current with positive and negative at the temperature of 60-65 ℃ to form a layer of 300-400nm oxidation film on the surface of the steel plate;
(6) coating: coating the polymer coating material on the surface of the oxidized steel plate by adopting a spraying or roll coating mode, then curing for 15-20min at the temperature of 160-180 ℃, cooling to room temperature, then coating the antibacterial coating material, and curing for 30-40min at the temperature of 50-60 ℃;
(7) and (4) placing the steel plate obtained in the step (6) in distilled water, and soaking for 6-8min at the temperature of 75-85 ℃ to obtain the scratch-resistant wear-resistant color coating steel plate.
Further, the concentration of the polyvinyl alcohol and the concentration of the glacial acetic acid in the step (2) are both 3-5 g/mL.
