Embodiment Construction

[0009] (1) Material treatment: For fiberboards with defective or uneven surface, use water-based putty to level them in batches, dry them at room temperature for 1 to 2 hours, and then polish them with sandpaper. The sandpaper is 240# to 360#. Medium density or high density fiberboard with a very smooth surface can directly enter the next process.

[0010] (2) Roller coating of water-based white primer: the white primer is selected to be quick-drying and has good hiding power; the thickness of each roller coating is 25-50um, 120-140℃ infrared drying for 3-5 minutes, use 240#~360 #Sandpaper light sanding, generally use a rubber roller, repeat the roller coating 2 to 3 times, each need to be polished.

[0011] (3) Roller intermediate coating primer: the construction method and the roller used are the same as the water-based white primer. The intermediate coating primer is generally toned, which is light brown, chestnut color or pink, ivory white, and a walnut color sample can be...

Abstract

The invention relates to a graining roll-coating production-line method for carpentry waterborne coating material on medium density fiber board. The invention is characterized by the following steps: (1) processing raw material; (2) roll coating waterborne white primer; (3) roll coating middle-coating primer; (4) roll printing to color; (5) roll coating fining varnish. The invention is advantageous in that the environment-friendly waterborne carpentry material and the novel coating method are applied on low-priced heavy density fiberboards to produce high-quality furniture boards with graining coating effect, provided with low coating consumption, high coating effectiveness and low coating cost]

Description

technical field [0001] The invention relates to an assembly line coating process of water-based wood paint on a medium density fiberboard with imitation wood grain effect. Background technique [0002] In the furniture coating industry, varnish pigmented coating occupies the vast majority of the market. Clearcoat pigmented applications are generally carried out on fibreboard veneered substrates. This style is popular because it retains the natural grain of the wood. With the growing demand for furniture, the price of natural wood has also risen, and it is increasingly unable to meet market demand. Moreover, the production cost of varnish coating is relatively high, and the efficiency is relatively low. In order to reduce production costs, some coating processes with imitation wood grain effects have emerged as the times require. Although the effect is different from that of natural wood varnish coating, it is greatly It meets the needs of some middle and low-end furniture...
