Abstract

The invention relates to a method for ensuring coating quality by using a covered film during coating and processing of veneers by photo-curing, and belongs to a chemical material. The method comprises the following steps: coating photo-cured paint on the surface of an artificial fiber board or an artificial shaving board by a roll brush, wherein the coating thickness is between 0.13 and 0.3 millimeter; covering a polyethylene film which has the thickness of between 0.05 and 0.2 millimeter and has good light transmission for ultraviolet light on the surface of a coated film; laying and placing the coated film in an ultraviolet light curing machine to irradiate for 1.73 to 10 seconds, coating film to finish curing; and lightly uncovering the film on the surface layer by hand after taking out the coated film. The method has the advantages of simple operation and easy grasp, production time and cost conservation; the method has no pollution during the process of coating a decorative panel, improves qualification rate of finished products, replaces a self-leveling process, reduces energy consumption, improves flatness and smoothness of the coated surface, and has strong practicability.

Description

technical field [0001] The invention relates to chemical materials, in particular to a method for ensuring the quality of coating by using a film in the process of photocuring coating and processing decorative panels. Background technique [0002] As we all know, at present, the commonly used production process of using light-curing coating to prepare decorative panels is to first coat the light-curing coating on the surface of the substrate, and then wait for the self-leveling process to be completed, and then put it into the light-curing device for curing Forming; Due to the arrangement of this coating process, the uncured and formed coating film is exposed to the production environment, and the storage time is relatively long, which greatly increases the risk of dust in the unclean air falling on the surface of the coating film, resulting in coating failure. Facing often produces pollution, which makes the qualified rate of finished products low and needs to be improved. ...
