Problems solved by technology

[0004] In the prior art, the furniture board needs to be sprayed twice to form the surface coating. The surface coating prepared by this process in the prior art is prone to defects such as "pinholes", "cracks", and "granules". The surface resistance is low, so that the finished board will have problems such as liquid penetration due to these defects in the surface coating during use, resulting in damage to the internal wood

Embodiment 1

[0072] A powder spraying treatment process on the surface of a wood panel is carried out through the following steps:

[0073] A, Carry out primary sanding treatment on the surface of the wood panel;

[0074] B, using UV putty paint for coating;

[0075] C, carry out drying for the first time and make the UV putty paint that step B is coated solidify;

[0076] D, carry out the second sanding treatment;

[0077] E, using UV primer for coating;

[0078] F, carry out drying for the second time to cure the UV primer coated in step E;

[0079] G, carry out one or more powder spraying.

[0080] In the surface powder spraying treatment process of the wood panel, the surface of the wood panel is first coated with UV putty paint and UV primer, and then powder sprayed. The UV layer is formed by coating the UV putty paint and the UV primer, the surface of the prepared plate has no defects such as pinholes and cracks, and the surface resistance test performance is good.

[0081] The...

Embodiment 2

[0083] A powder spraying treatment process on the surface of a wood panel is carried out through the following steps:

[0084] A. Use 240#~320# abrasive belts to perform primary sanding treatment on the surface of the wood panel.

[0085] B. Heat the UV putty paint to 15-20°C and then apply it. The specific process is as follows:

[0086] Use UV putty paint according to the first coating direction, coating 10 ~ 15g / m 2 The first putty paint layer, the thickness of the first putty paint layer is 5-7 μm; stop for 2-5 minutes after the first putty paint layer is coated;

[0087] Then use UV putty paint to apply 13-25g / m on the surface of the first putty paint layer according to the second coating direction 2 The second putty paint layer, the thickness of the second putty paint layer is 5-10 μm; stop for 2-5 minutes after the second putty paint layer is coated;

[0088] Then use UV putty paint to apply 20-35g / m on the surface of the second putty paint layer according to the thi...

Embodiment 3

[0106]A kind of surface powder spraying treatment process of wood panels, other features are the same as embodiment 2, the difference is: in the process of carrying out UV putty paint coating in the step B, keep the ambient temperature as 15~20 ℃, at this ambient temperature Under the circumstances, during the UV putty coating process, the pits on the surface of the board are in the best state, and the bonding method of the UV putty on the surface of the board is the best. The coated UV putty can seal the vacuum on the surface and avoid all Defects such as vacuum appear on the surface of the prepared coating. At the same time, in this environment, the performance of UV putty is also at its best.

[0107] During the process of coating the UV primer in step E, keep the ambient temperature at 15-20°C. Under this ambient temperature, the UV primer and the UV putty layer can be effectively bonded, and the surface of the formed UV primer layer is smooth without through holes, crack...

Abstract

The invention provides a wood board surface powder spraying treatment technology. The wood board surface powder spraying treatment technology comprises the following steps of (1) carrying out primary sanding treatment on the surface of a wood board, (2) carrying out spraying with UV putty paint, (3) carrying out the first time of drying to solidify the UV putty paint sprayed in the step (2), (4) carrying out the second time of sanding treatment, (5) carrying out spraying with UV primer, (6) carrying out the second time of drying to solidify the UV primer sprayed in the step (5), and (7) carrying out one time or more than one time of powder spraying. A coating prepared with the wood board surface powder spraying treatment technology is good in surface resistance and high in surface quality; and the wood board surface powder spraying treatment technology has the advantages of being high in spraying speed, low in cost, high in the pass percent of prepared products and the like.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a powder spraying treatment process on the surface of a wood panel. Background technique [0002] Furniture is one of the indispensable daily necessities in people's life. With the development of society, not only the shape of furniture has undergone changes again and again to develop in a more beautiful direction; the various performances of furniture are also developing in a more and more excellent direction. [0003] The boards used as furniture usually need to be powder-coated to make the boards have specific surface layers. These surface layers have the function of protecting the boards, and can also form characteristic patterns, textures, etc. according to specific needs. [0004] In the prior art, the furniture board needs to be powder sprayed twice to form the surface coating. The surface coating prepared by this process in the prior art is prone to defects such as "pi...
