Problems solved by technology

However, researchers have found through research at home and abroad that water-based wood coatings have the following disadvantages: on the one hand, they are relatively dry after film formation and relatively poor in permeability; Corrosion resistance and solvent resistance are also weak, so it is only suitable for low-end products, and its cost price is relatively high

Embodiment 1

[0046] Embodiment 1, the coating process of a kind of water-based wood coating of the present embodiment, comprises the steps:

[0047] (1) Coating of water-based primer

[0048] Pretreatment of wooden furniture: Use 240# sandpaper to polish the surface of the furniture, and use a BM8 special-shaped sander to trim and polish the unevenness or burrs. After the grinding is completed, immediately apply a water-based primer cloth;

[0049] Coating is carried out by spraying, and the coating amount is 55g / m2. After the coating is completed, it is put into an infrared and hot air assisted drying tunnel for drying treatment.

[0050] (2) background color

[0051] The above-mentioned dried primer layer is polished again with 320# sandpaper, and polished with a BM8 special-shaped sander. After it is even and uniform, the bottom layer is colored; the coloring is mainly done by hand, and the requirements are: clear texture and layering Strong, effective and controllable color quality;...

Abstract

A coating process for water-borne woodenware paint comprises the following steps of (1) coating of waterborne primer, (2) bottom color applying, (3) coating of first paint, (4) coating of second paint, (5) color repairing, (6) coating of waterborne UV finish paint, and the like. The coating process can be better used for high-end products, and using cost is reduced.

Description

technical field [0001] The invention relates to the field of paint coating, in particular to a coating process of water-based wood paint. Background technique [0002] Water-based wood coatings are generally made of acrylic emulsion, which has many advantages, such as acrylic emulsion has high solid content, fast drying speed, strong hardness, good weather resistance and low cost. In addition, water-based wood coatings have very low VOC It has a great effect on reducing the pollution emission of coatings in woodware and furniture enterprises, so it is widely used. However, researchers have found through research at home and abroad that water-based wood coatings have the following disadvantages: on the one hand, they are relatively dry after film formation and relatively poor in permeability; Corrosion resistance and solvent resistance are also weak, so it is only suitable for low-end products, and its cost price is relatively high. How to improve the water-based wood coati...
