Description
Technical Field
[0001] The invention relates to the technical field of furniture coating, in particular to a method for coating the surface of a bamboo product. Background Art
[0002] As the scope of whole-house customization becomes wider and wider, more consumers begin to reject stereotyped designs. In order to cater to the mainstream trend of the world, the design of furniture products will develop in the direction of making the materials infinitely close to nature. The skin-feeling seamless effect has become the CP combination of high-end customized furniture. The traditional painting process of paint furniture is generally white blank grinding, primer, primer grinding, and then direct surface coloring and topcoat. The primer, polishing, and coloring process are simple and only done once. It cannot effectively solve the problems of burrs and poor fullness of primer film, which adds difficulties to the later painting. In addition, the traditional paint coating process has defects such as whitening, drying, and blurred texture of the duct, which cannot make the wood grain clear, realistic, and three-dimensional, and fully reflect the natural veneer. In the traditional paint furniture painting process, only one surface coloring is performed, which makes the finished furniture have the hidden danger of color difference. In the traditional open paint furniture painting process, only one surface coloring is performed, which makes the finished furniture have the hidden danger of color difference, and the existing furniture cannot achieve waterproof and mold-proof effects after painting.

[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] See also Figure 1 As shown, the present invention provides a method for coating the surface of a bamboo product, and the coating process comprises the following steps:
[0027] Step S1: adsorb multiple embryonic plates on the overhead crane, and then use the grinding parts to grind the surfaces of the multiple embryonic plates.
[0028] After polishing, the crane will transfer the embryonic board;
[0029] Step S2, the overhead crane transports a plurality of blanks to a paint pool with an open upper surface, immerses the blanks, and attaches the primer to the blanks, thereby achieving primer immersion of the blanks;
[0030] Step S3: After soaking in primer, let the board dry for a certain period of time when transporting by overhead crane, and then wipe off the excess primer on the board.
[0031] Make the primer adhere better to the surface of the board;
[0032] Step S4: After wiping dry, the crane transports the plate to the drying mechanism for drying. After drying, the plate is then transferred to the polishing unit for primer sanding to increase the smoothness of the plate, better achieve coloring on the surface of the plate, and make it more solid.
[0033] Avoid uneven coloring.
[0034] Step S5, finally, the surface of the board is painted with paint, and after the painting, it is dried again and formed. The board after the painting and forming can achieve the effect of being waterproof and mold-proof.
[0035] The primer comprises a main agent, a curing agent and a diluent, wherein the ratio of the main agent, the curing agent and the diluent is 1:0.5:0.7, and the main agent is Depoxetine. The main agent, the curing agent and the diluent are mixed in proportion and stirred for 8-9 seconds to form the primer.
[0036] The primer is equivalent to a closed primer (a very thin layer that soaks into the wood), which serves as a bottom seal. PS900 can be used for sealing, spraying, wiping or brushing. Its purpose is to prevent sinking and facilitate uniform coloring; but the corners should be sealed thicker to avoid uneven coloring when the bottom is colored.
[0037] Generally, Depo and its curing agent are mixed and used. The mixing ratio of Depo and its curing agent is indicated on the package. Sealing the wood bottom is to seal the bottom layer of the wood to prevent the color from returning, and the curing agent is to make the paint dry and solidify quickly.
