Problems solved by technology

[0003] The production process of decorative panels with leather or fabric surfaces is usually to apply glue on the surface of the substrate, and then press the leather or fabric on the glue. The initial structure is relatively strong, but during use, the leather or fabric tends to start from the edge of the substrate. Separation occurs, resulting in edge warping, and then gradually expands the area of ​​separation, which affects the use effect, and requires improvement of the production process

Embodiment 1

[0024] A composite production process of decorative board edge wrapping, comprising the following steps:

[0025] Substrate processing, milling a square groove on both sides of the bottom of the substrate, and cutting a gap extending into the substrate on the inner edge of the square groove, the square groove is perpendicular to the gap, and the depth of the square groove is the same as The material thickness of the veneer layer is corresponding, which can improve the flatness of the bottom surface of the decorative board. Round the edges on both sides of the top and bottom of the substrate to remove burrs and sundries. Three layers of 1cm felt are superimposed between two layers of PE film, and then hot-pressed, the thickness is fixed to 1cm, the structure is firm, and it is not easy to deform;

[0026] For the processing of the veneer layer, the veneer layer is made of leather or fabric, and the width of the veneer layer is cut according to the width of the top surface of th...

Embodiment 2

[0031] A composite production process of decorative board edge wrapping, comprising the following steps:

[0032] Substrate processing, milling a square groove on both sides of the bottom of the substrate, and cutting a gap extending into the substrate on the inner edge of the square groove, the square groove is perpendicular to the gap, and the depth of the square groove is the same as The material thickness of the veneer layer is corresponding, which can improve the flatness of the bottom surface of the decorative board. Round the edges on both sides of the top and bottom of the substrate to remove burrs and sundries. Two layers of 1cm felt are superimposed between two layers of PE film, then hot-pressed and compressed to 0.5cm in thickness, the structure is firm, not easy to deform, and has a good anti-mildew effect;

[0033] For the processing of the veneer layer, the veneer layer is made of leather, and the width of the veneer layer is cut according to the width of the to...

Abstract

The invention discloses a composite production process of wrapping edges of decorative plates, the process comprises the following steps: processing a substrate, processing a veneering layer, compounding, rolling, processing a back layer, coating a layer of adhesive on the bottom of the substrate, covering the adhesive with the back layer, and curing and shaping. Through the composite production process, square grooves and gaps are particularly processed at the bottom of the substrate to fix the two ends of the veneering layer, wrapping of the top surface and the two side surfaces of the substrate can be realized, the back layer covers the veneering layer in the square grooves, and the composite production process has good edge pressing effect, and avoids the problem of cracking and separation of the veneering layer.

Description

technical field [0001] The invention relates to the technical field of decorative boards, in particular to a composite production process of decorative board edge wrapping. Background technique [0002] Decorative panels are widely used in indoor and outdoor decoration, furniture manufacturing and other fields. Along with the improvement of people's living standard, when carrying out house decoration, the requirement to decorative panel is getting higher and higher, and in recent years, the decorative panel with the surface of leather or fabric has been sought after by people. [0003] The production process of decorative panels with leather or fabric surfaces is usually to apply glue on the surface of the substrate, and then press the leather or fabric on the glue. The initial structure is relatively strong, but during use, the leather or fabric tends to start from the edge of the substrate. Separation occurs, resulting in edge warping, and then gradually expands the area ...
