Process for painting surface of profiled edge by UV (ultraviolet) curing

Abstract

The invention discloses a process for painting a surface of a profiled edge by UV (ultraviolet) curing. The process comprises the following steps: A, the surface of the profiled edge of a workpiece is subjected to white body sanding by means of a profile sanding machine; B, UV sealing primer is coated on the workpiece in a rolling mode by the profile roll coater; C, UV curing is carried out on the UV sealing primer; D, the surface of the profiled edge of the workpiece is subjected to primer sanding by means of the profile sanding machine; E, UV transparent primer is coated on the workpiece in a rolling mode by the profile roll coater; F, UV curing is carried out on the UV transparent primer; and G, PU finish paint is sprayed on the surface of the profiled edge of the workpiece by man power. The process realizes the effects of high smoothness, strong dimensional sense and clear texture of the surface of the profiled edge of furniture workpieces.

Description

technical field [0001] The invention relates to a paint process, in particular to a UV ultraviolet light curing paint process on the surface of special-shaped edge lines of furniture workpieces. Background technique [0002] The current painting process is to simply process the surface of the utensil, then spray the paint, and then form it after drying. With the improvement of people's living standards, the continuous change of furniture styles requires more beautification of the peripheral lines of the board surface, such as curved edges, duckbill edges and other special-shaped edges. Such as figure 1 As shown, the traditional surface painting process of furniture special-shaped edge is to firstly spray PU sealing primer on the surface of wooden furniture manually, and then manually sand the edge after drying for 12 hours; then manually spray PE primer, and dry it for 24 Hours later, sand the edges manually, and finally spray the PU topcoat manually. [0003] The above-m...

Problems solved by technology

[0003] The above-mentioned painting process, because the PE primer needs 24 hours to dry at room temperature, makes the whole production cycle long; the whole process is manually operated, which not only has high labor intensity and low production efficiency, but also artificial polishing will cause uneven furniture surface quality and uneven lines , not smooth, easy to damage, resulting in high scrap rate, low utilization rate of paint due to artificial spraying of paint, high cost; dust generated in the process of grinding and sanding not only pollutes the workshop environment, but also affects the health of operators harm

Obviously, the existing special-shaped edge surface painting process can no longer meet the increasingly higher quality of modern furniture and the increasingly higher requirements of modern society for production efficiency and production environment
