Problems solved by technology

[0003] At present, ordinary color-coated sheets are made of cold-rolled sheets or galvanized sheets as substrates, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated with oily paint, baked at high temperature, and cooled. Coated on-line wire drawing function; the use of oil-based paint and a large amount of thinner in the production process has a certain impact on the environment of the production workshop, and has a certain degree of harm to the body of the operator. In the production process, high-temperature baking is required, and energy High consumption, high temperature operation risk, and oil-based paint and thinner are flammable and explosive, posing safety hazards

Abstract

The invention provides a wiredrawing UV color-coated sheet and a preparation method thereof. The wiredrawing UV color-coated sheet comprises a metal substrate, a first zinc layer, a second zinc layer, a wiredrawing layer, a first passivation layer, a back paint layer and a UV layer. The wiredrawing UV color-coated sheet is prepared through galvanization treatment, wiredrawing treatment, passivation treatment and UV coating and back paint coating. The surface of the prepared wiredrawing UV color-coated sheet has the wiredrawing effect and high metal texture, so that a color-coated product has the wiredrawing effect while having the anti-corrosion function; practicability and special-effect attractiveness are achieved, the product variety is enriched, the market competitiveness is improved, and diversification of color-coated sheet products is achieved; and moreover, a color coating on-line drawing process and a UV curing process are newly added, so that the production process is simplified, the energy consumption is reduced, the production cost is reduced, and the problem that a color coating line does not have a color coating on-line drawing function in the preparation process of an existing common color-coated sheet is solved.
