UV (ultraviolet) paint veneering plywood and method for coating special-shaped base material

Abstract

The invention discloses UV (ultraviolet) paint veneering plywood and a method for coating a special-shaped base material. The UV paint veneering plywood for coating the special-shaped base material comprises heatable and bendable plywood, a non-woven fabric, a wood veneer, a UV paint surface and a PET (polyethylene terephthalate) protective film. A coating groove which corresponds to the special-shaped base material is formed in the lower surface of the heatable and bendable plywood, hot melt coating adhesive is arranged in the coating groove, the heatable and bendable plywood is adhered on the special-shaped base material by the hot melt coating adhesive, the non-woven fabric is laminated between the upper surface of the heatable and bendable plywood and the lower surface of the wood veneer, the UV paint surface is arranged on the upper surface of the wood veneer, and the PET protective film is arranged on the UV paint surface. The UV paint veneering plywood and the method have the advantages that various shapes can be formed according to different special-shaped base materials by the aid of a coating technology of the environment-friendly UV paint veneering plywood, so that the product diversity and the high efficiency are improved for finished wood sections in the decoration and household industries.

Description

technical field [0001] The invention relates to a UV paint-faced plywood for coating a special-shaped base material and a method thereof, in particular to an environment-friendly UV paint-faced plywood and a related coating method for covering a special-shaped base material. Background technique [0002] In the veneer cladding industry, the traditional cladding is clad by unpainted veneer, and the cladding veneer is 0.1-0.5 mm. The difficulty is that after the veneer is covered, it encounters various adverse phenomena such as blistering and delamination, and after the veneer is covered, it needs to spend a lot of manual polishing and painting. The dust pollution generated during traditional grinding is very harmful. Dust pollution directly threatens people's lives, especially living in a dust-polluted environment can cause a variety of cardiovascular and respiratory diseases, and its traditional painting operations have always endangered people's physical and mental health ...

Problems solved by technology

The difficulty is that after the veneer is covered, it encounters various adverse phenomena such as blistering and delamination, and after the veneer is covered, it needs to spend a lot of manual polishing and spraying paint, etc.

Dust pollution generated during traditional grinding is very harmful

Dust pollution directly threatens people's lives, especially living in a dust-polluted environment can cause a variety of cardiovascular and respiratory diseases, and its traditional painting operations have always endangered people's physical and mental health and polluted the environment. In traditional spray painting Contains excessive formaldehyde, benzene, toluene and xylene and other harmful substances. These substances all contain volatile toxic gases, causing environmental pollution, and are also very harmful to the human body.

[0003] In addition, in the traditional technology, people have also tried to bend the painted veneer plywood at a right angle. The defect of the right angle bending process is that it cannot bond and form the veneer plywood on any special-shaped substrate. Therefore, the existing right-angle The bending process cannot solve the various and different sizes of special-shaped lines that people need in the decoration industry
