Problems solved by technology

[0004] However, in actual production and processing, some natural or technical veneers have poor composite properties with non-woven fabrics or kraft paper
Or the gaps in the texture of some wood veneers cannot achieve the ideal paint filling effect after roller coating

Embodiment 1

[0025] The surface layer is natural cherry veneer with a thickness of 0.2mm, with a thickness of 0.09mm and a surface density of 29g / m 2 The imported non-woven fabric is the bottom material, and the hot-melt adhesive film paper is laid flat between the bottom layer and the surface layer, which is put into a hot-pressing machine for hot pressing. The hot-pressing temperature is 140°C and the hot-pressing pressure is 1.3MPa. Cut the composite non-woven veneer to a regular size of 2500mm x 630mm in length, then flatten and fix the cut veneer on a flat and flexible board, and then put the board and the above-mentioned composite veneer into the UV primer roller Coating production line, after roller coating, sanding treatment. After natural aging. After detection, it is supplied to downstream customers in a single flat state.

Embodiment 2

[0027] Use natural red oak veneer with a thickness of 0.25mm as the surface layer, with a thickness of 0.1mm and a surface density of 30g / m 2 The kraft paper is the bottom material, and the hot-melt adhesive film paper is used between the layers. Put it into the hot-pressing machine for hot-pressing and compounding. The hot-pressing temperature is 145°C and the hot-pressing pressure is 1.35MPa. Cut the compounded kraft paper veneer to a size of 2600mm x 870mm in length, then flatten and fix the cut veneer on a flat and flexible board, and then put the board and the above-mentioned composite veneer into the production line with UV primer roller coating , After the roller is painted, it is then sanded. After natural aging. After detection, it is supplied to downstream customers in a single flat state.

Abstract

The invention provides a plane single-sheet compound veneer with UV (Ultraviolet) primer. A multilayered structure is adopted; a surface layer is a veneer layer and a bottom surface is a nonwoven fabric or kraft paper; a compound adhesive is arranged between layers. UV paint is arranged into a microcosmic gap of a wood layer. The veneer has good flexible property, stability and good post process treatment property. The veneer can be laminated or coated on an abnormal-shape surface of any material. The secondary treatment or machining property is good and the veneer is stable and reliable. Compared with a traditional pasted veneer surface treatment process, a lot of process procedures are saved and the labor cost is saved, so that the production cost and technology cost of downstream products are reduced and the economic benefits of the downstream products are greatly improved.

Description

technical field [0001] The invention relates to a decorative material, in particular to a flat single sheet composite veneer with UV primer. Background technique [0002] Natural veneer refers to the flaky wood material obtained by planing or rotary cutting of wood. It is widely used in the surface decoration treatment of high-end furniture, solid wood composite floors, doors, window frames and baseboards of any material, and decorative walls. The veneer reflects the beautiful texture of natural wood, giving people the feeling of real wood, thus saving a lot of wood resources. It can also meet the aesthetic needs of consumers. Because the natural veneer is brittle, it will be brittle or broken after being bent at 90 degrees, so it can only be directly pasted or coated on the plane. For shapes with corners of 90 degrees or greater, only edge banding strips can be used alone Tape the other corner of the right angle. Affected the overall coordination and aesthetics of the pr...
