Embodiment

[0046] Example: see figure 1 , figure 2 , an online roller coating process for producing high-gloss panels with solvent-free UV coatings, comprising the following steps:

[0047] S1. After the plastic sheet is formed on the extruder, it passes through the roller coating machine, and the solvent-free UV coating is evenly rolled onto the plastic sheet by the coating roller;

[0048] S2. The plastic sheet passes through the laminating machine, and the release protective film covers the surface with the paint on the plastic sheet and is pressed flat. After that, the plastic sheet is cured by UV, and the paint is cured by the ultraviolet light that penetrates the protective film. After UV curing, the release protective film on the surface of the plastic sheet is peeled off from the sheet after cooling, and a hardened and wear-resistant coating layer with high gloss and high flatness can be obtained on the surface of the plastic sheet.

Abstract

The invention discloses an online double-sided roller coating process and device for producing high-brightness panels by using a solvent-free UV coating. The process comprises the following steps: uniformly coating the solvent-free UV coating on plastic panels molded on an extruder by virtue of a roller coater, covering a release protection film on the surface with the coating on plastic panels by virtue of a laminating machine, flatly pressing, performing UV curing on the plastic panels, curing the coating by virtue of ultraviolet light penetrating through the protection film, cooling, stripping the surface release protection film and the panels, thereby obtaining the hardened wear-resistant coating layer with high glossiness and high flatness on the surface on the surface of the plastic panels. The process and the device disclosed by the invention are suitable for online double-sided roller coating or online single-sided roller coating, the PET films or other transparent and semi-transparent films serving as the release protection films are compounded with the panels, and the surface leveling problem generated by online roller coating of the plastic panels is solved.

Description

technical field [0001] The invention discloses an on-line double-sided roller coating process and device for producing high-gloss panels with solvent-free UV coatings, in particular to a UV (ultraviolet light) curing coating with high light transmission and high gloss effects on the surface of transparent panels. Layer in-line double-sided roller coating process. Background technique [0002] Transparent plastic sheets, such as polymethyl methacrylate (PMMA) sheets, polycarbonate (PC), polystyrene (PS) sheets and other transparent sheets, have high gloss and high transparency on the surface, but the surface is very It is easy to scratch, so a layer of hardened and wear-resistant coating on the surface can make the surface less likely to be scratched. The transparent plastic plate coated with hardened and wear-resistant paint has a wide range of uses, such as mobile phone panels, electrical nameplates, advertising materials, furniture panels, cabinet panels, etc. Plastic sh...
