Abstract

The invention discloses a coating process of water-based colorful paint on the surface of furniture, which comprises the following steps: 1) plate pretreatment: use 24# sandpaper to roughly grind the plate until the plate is flat, and then use a damp cloth to wipe the plate; use 180# sandpaper to finely Grind the board in the wood grain direction, remove burrs, and then remove dust; 2) Paint the board: use paint roller coating equipment to spray primer on the board, and the thickness of the primer is 0.5‑0.7mm. The invention improves the drying speed of the topcoat, thereby improving the production efficiency, and the topcoat is condensed together, no cracks will not be broken, and it is not easy to fall off. The topcoat has high stability, good durability, and improved gloss, so The furniture is more beautiful; and the bonding effect between the top coat and the primer is good, the top coat at the bottom is completely bonded to the primer, the connection between the two is stable, and it is not easy to separate and delaminate.

Description

technical field [0001] The invention belongs to the technical field of furniture manufacturing, and in particular relates to a coating process of water-based colorful paint on the surface of furniture. Background technique [0002] Water-based colorful paint has the advantages of environmental protection, non-toxic, odorless performance, etc., so it is often used in furniture. Support from consumer groups; however, during the painting process of existing water-based colorful paints, due to the painting process, the bonding firmness between the topcoat and the primer is poor, and the topcoat is prone to paint peeling during use , reducing the aesthetics of the furniture. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a coating process of a water-based multi-color paint on the surface of furniture with a good bonding effect between the top paint and the primer. [0004] In order to achieve the above...
