Roller-coating and spray-coating mixed production process for log cabinet body of UV paint furniture

Abstract

The invention discloses a roller-coating and spray-coating mixed production process for a log cabinet body of UV paint furniture. The process comprises the following steps of fixed-thickness sanding,UV primer roller-coating for sealing wood pores, paint surface sanding for increasing the UV physical adhesive force in the subsequent procedure, secondary UV primer roller-coating for increasing theplumpness of a paint film, primer sanding, numerical control machining, cut edge physical repairing, UV finish paint spray-coating, paint surface physical repairing treatment, color matching and the like. According to the process, UV paint is applied to a log board, and the thickness of the paint film is greatly related to the wood, texture, hardness, splicing width, moisture, adsorption force anddamp-proof stability of the log board; the problems of miniaturization of production equipment and reduction of production cost are solved; and various adverse effects such as paint surface drawing,napping and granulation cannot be caused during UV paint roller-painting of the log board.

Description

technical field [0001] The invention relates to an incineration treatment technology, in particular to a mixed production process of roller coating and spray coating of UV lacquered furniture log cabinets. Background technique [0002] At present, the cabinet materials used in large quantities in the home improvement customization industry: 18mm particle board (Daya, Lushuihe, Guodong, Crossbang, etc.) The surface treatment uses melamine coating for patterns, which contains formaldehyde and has poor water resistance. It is waterproof and moisture-proof by the edge banding, and it is easy to fall apart and deform when absorbing moisture; 18mm multi-layer laminated solid wood board (three thousand square multi-layer laminated eucalyptus veneer, ordinary eleven-layer laminated mixed veneer, ordinary nine-layer laminated mixed veneer) for surface treatment The pattern is made of melamine coating, which contains a lot of formaldehyde. The edge sealing method is used to prevent mo...

AI Technical Summary

Problems solved by technology

[0004] 1. Process the wood into the required size and assemble it into a board with a core frame separated. The processing time is long, the technical requirements are high, and it is prone to missing parts, and at the same time increases the chance of worker injury

[0005] 2. The assembly and punching speed of the frame structure is slow, which increases the processing time and increases the time for the log to absorb moisture and deform

[0006] 3. Solid wood production has high technical requirements for workers, and it is difficult to train them in a short period of time. Old carpenters have relatively low education and cannot quickly learn the operation of modern engraving machines. Difficult to grasp in place

[0007] 4. The equipment required for production requires large investment and high energy consumption

[0008] 5. The production method of the log cabinet body is first made into a single piece and then polished. The polishing time is long, especially in the groove part, the labor intensity of the workers is high, and the manual polishing is uneven.

[0009] 6. The quality of spraying is not easy to grasp. It takes a long time to dry, and a larger space is required to place semi-finished products. The workpiece absorbs water for a long time, causing expansion and deformation. Manual spraying has the possibility of spraying on the outside of the workpiece or on the ground, resulting in a large waste of excess sprayed paint. , which increases the cost and produces huge exhaust gas and dust pollution
