Abstract

The invention relates to the technical field of paint spraying, in particular to a wooden product UV primer vacuum spraying method and a UV primer sprayed wooden product. The wooden product paint spraying method comprises the following specific steps: wooden products to be treated are pretreated to obtain pretreated wooden products; vacuum spraying of polyester compounded UV primers is performed on the pretreated wooden products at least once; and UV primer wooden products are obtained through polishing and sanding after ultraviolet curing and drying. The polyester compounded UV primers are adopted for at least one-time vacuum spraying in the process, and the ultraviolet curing and drying treatment is performed in time; and the obtained UV primer wooden products can reach adhesive force ofgrade 0, are excellent in smoothness, meet requirements, and are simple in preparation process, short in time and capable of meeting the demands of a traditional spraying process.

Description

technical field [0001] The invention relates to the technical field of paint vacuum spraying, in particular to a method for vacuum spraying paint on wood products and wood products with UV primer spraying. Background technique [0002] UV primer layer spraying is an indispensable step in the wood product painting process, which can affect the subsequent paint spraying process to a certain extent and affect the performance parameters of the entire paint layer. [0003] In the existing painting process, the UV primer vacuum spraying specifically includes three sprayings, wherein the UV primer is sprayed and leveled and subjected to ultraviolet light curing and drying treatment, and the first UV primer wood product obtained is then sanded. The same UV primer coating and drying process is used for the second spraying, and the obtained second UV primer wood product is sanded, and then the same UV primer coating and drying process is used for the third spraying process.
