Problems solved by technology

The existing traditional furniture and wooden doors are basically painted with traditional polyurethane (PU) two-component paints, nitro paints and other solvent-based paints. When using such paints to paint furniture, etc., a large The production area and the curing time of the coating are long, and this traditional polyurethane (PU) coating contains organic solvents, which will produce volatile organic compounds, which will generate a large amount of volatile organic compounds during the coating process, and cause serious damage to the atmospheric environment. impact, which largely outweighs the use of traditional coating methods
Some factories have begun to use UV coatings, but only some of the coatings are made of UV coatings and not the entire coating, and some UV coatings still contain organic solvents, which still produce high emissions of volatile organic compounds

Embodiment 1

[0030] This embodiment provides an exemplary method for coating a planar piece, said method comprising the steps of:

[0031] 1) Use 80#, 100#, 120# sandpaper to sand the plain board respectively;

[0032] 2) Manually wipe the surface of the plain board treated in step 1) with UV-water-based color wiper, with an amount of 8-12g / m2 2 , drying by infrared rays at 70°C for 10 minutes,

[0033] 3) Use a putty roller coater to coat the UV-roller filling putty with an amount of 30-40g / m 2 , 150mJ / cm 2 After UV curing, polish with 240# sandpaper, and paint twice continuously to fill the wooden holes;

[0034] 4) Apply UV-roller sanding primer with a laser roller coater, with an amount of 30-40g / m 2 , leveling for 15 seconds, 80mJ / cm 2 UV semi-curing, the surface is slightly sticky;

[0035] 5) Use UV-laser roller to coat the primer with a laser roller coater, with an amount of 40-50g / m 2 ;Leveling for 15 seconds, 180mJ / cm 2 Polish with 400# sandpaper after UV curing;

Embodiment 2

[0041] The present embodiment provides a kind of exemplary method that is used for coating planar parts, and its coating step is identical with embodiment 1, just UV-water-based coating is replaced with one-component water-based coating, and concrete steps are as follows:

[0042] 1) Use 80#, 100#, 120# sandpaper to sand the plain board respectively;

[0043] 2) Manually wipe the surface of the plain board treated in step 1) with water-based PUD color wiper, with an amount of 8-12g / m 2 , drying by infrared rays at 70°C for 10 minutes,

[0044] 3) Use a putty roller coater to coat the UV-roller filling putty with an amount of 30-40g / m 2 , 150mJ / cm 2 After UV curing, polish with 240# sandpaper, and paint twice continuously to fill the wooden holes;

[0045] 4) Apply UV-roller sanding primer with a laser roller coater, with an amount of 30-40g / m 2 , leveling for 15 seconds, 80mJ / cm 2 UV semi-curing, the surface is slightly sticky;

[0046] 5) Coat the UV-laser roller coatin...

Embodiment 3

[0052] This embodiment provides a kind of exemplary method for coating planar parts, and its coating steps are identical with embodiment 2, just replace single-component water-based paint with two-component water-based paint, concrete steps are as follows:

[0053] 1) Use 80#, 100#, 120# sandpaper to sand the plain board respectively;

[0054] 2) Manually wipe the surface of the plain board treated in step 1) with water-based PUD color wiper, with an amount of 8-12g / m 2 , drying by infrared rays at 70°C for 10 minutes,

[0055] 3) Use a putty roller coater to coat the UV-roller filling putty with an amount of 30-40g / m 2 , 150mJ / cm 2 After UV curing, polish with 240# sandpaper, and paint twice continuously to fill the wooden holes;

[0056] 4) Apply UV-roller sanding primer with a laser roller coater, with an amount of 30-40g / m 2 , leveling for 15 seconds, 80mJ / cm 2 UV semi-curing, the surface is slightly sticky;

[0057] 5) Coat the UV-laser roller coating primer with a la...

Abstract

The invention discloses a coating method for furniture. A water-based coating and a UV coating which are jointly used are adopted in the method. The method comprises the following selected steps that firstly, a base material is provided; secondly, a water-based color wiping agent is applied to the surface of the base material, and the usage amount of the water-based color wiping agent is 8 g / m<2>-12 g / m<2>; thirdly, UV putty is applied, and the usage amount of the UV putty is 30 g / m<2>-40 g / m<2>; fourthly, UV primer is applied, and the usage amount of the UV primer is 30 g / m<2>-50 g / m<2>; fifthly, water-based primer is applied, and the usage amount of the water-based primer is 100 g / m<2>-110 g / m<2>; sixthly, a water-based color modifying agent is applied, and the usage amount of the color modifying agent is 20 g / m<2>-30 g / m<2>; and seventhly, water-based finish paint is applied, and the usage amount of the water-based finish paint is 100 g / m<2>-110 g / m<2>. In the third step, applying is finished through a roller painting manner. In the fourth step and the fifth step, applying is finished through one of a roller painting manner and a spraying manner or the combination manner of roller painting and spraying. In the sixth step, applying is finished through a spraying manner. In the seventh step, applying is finished through a spraying manner. The furniture is provided with a flat surface or a non-flat surface. By means of the coating method, the product performance is improved, environment friendliness is achieved, and implementation is easy.

Description
