Technology for painting wooden products with coating agents instead of PU primer or PE primer

Abstract

The invention provides a technology for painting wooden products with coating agents instead of PU primer or PE primer. The wooden products are divided into solid wood and veneer, wherein the solid wood is divided into large pieces and small pieces, and the products which are small in size and can be soaked are all the small pieces; the coating agents are used for replacing the PU primer or the PE primer to soak and paint the small pieces among the solid wooden products; the coating agents are used for replacing the PU primer or the PE primer to paint the large pieces among the solid wood products; the coating agents are used for replacing the PU primer or the PE primer to conduct erasing coating on the veneer products. The coating agents are used as the primer to paint the wooden products. Painted workpieces are good in wood grain filling property, a paint film is high in transparency and good in fullness, the use amount of the paint is small, and the solid content of the coating agents exceeds 99 percent. By means of the technology, air pollution will not occur in the producing and painting process, no waste is caused, and the effects of environment protection and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of furniture paint coating technology, in particular to a technology for coating wood products with a film coating agent instead of a PU or PE primer. Background technique [0002] At present, with the improvement of national consumption level, people have more choices and higher requirements when choosing furniture, wooden doors and other wood products. Therefore, furniture and other wood products companies mostly focus on personalized and complex shapes when designing products. Design concept, 90% of furniture wooden door manufacturers will use PU paint as the main paint primer when painting with paint, but the solid content of PU paint is only 40%, and the thinner will evaporate during the drying process, causing great damage. air pollution. Due to the low solid content, if you want to achieve the effect of closing the wooden holes, you need two to three coats of spraying. [0003] Moreover, the sprayin...

[0003] Moreover, the spraying process is used for painting. During the spraying construction project, 50% of the paint will be sprayed directly into the air and become industrial waste, which is difficult to deal with and makes the enterprise bear the double pressure of environmental protection and waste of cost.

In addition, due to the long drying time during the construction of PU paint, it often takes more than 12 hours to polish. The sprayed workpiece must be placed on a drying rack to dry, which takes up a large area of ​​the site. If you want to dry quickly, you must increase Infrared drying room increases equipment and power consumption. Generally, it takes about a week to complete the paint coating of the workpiece from the bottom to the surface. The delivery cycle is too long.
