Anti-flame large-breadth width-splicing dipping decoration veneer and manufacturing method thereof

Abstract

The invention particularly relates to an anti-flame large-breadth width-splicing dipping decoration veneer and a manufacturing method thereof. The anti-flame large-breadth width-splicing dipping decoration veneer is obtained by using the veneer as a raw material, after softening surface pretreatment of a veneer softener, drying, cold-pressing and shaping, after length-splicing, bottoming, sanding,width-splicing, dipping flame-retarded resin and drying, and spraying a wear-resisting agent, dipping the flame-retarded resin again and drying. The beneficial effect is that firstly a mode of longitudinal length-splicing and horizontal width-splicing is used, lossless preparation of the large-breadth decoration veneer is realized, a wood raw material is avoided wasting, and simple production isrealized; secondly, with the help of a special structure and performance of sepiolite powder, the flame-retarded resin prepared by a flame retardant and resin is combined, the veneer is dipped for twotimes, and the veneer is endowed with everlasting flame resistance; thirdly, an electrostatic spraying technology is used for spraying the wear-resisting agent, and a resin-closing method is used, the wear-resisting agent is prevented from being settled and aggregated in the resin, so the wear-resisting agent can be uniformly dispersed on the dipping veneer.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a flame-retardant large-format and width-impregnated decorative veneer and a manufacturing method thereof. technical background [0002] Decorative veneer is a widely used interior decoration material. Because the base material of decorative veneer is generally a precious tree species with beautiful patterns and good texture, and the production requires a large diameter, its development is limited. With the advancement and development of technology, through the lamination and compounding of fast-growing wood or wood-based panel base material and precious wood veneer, the utilization efficiency of precious wood can be greatly improved under the premise of ensuring the "decorative" quality of the product. At present, veneer veneer is widely used in home decoration, solid wood composite flooring and furniture production, but there are still some technical difficulties when...

Problems solved by technology

At present, veneer veneer is widely used in home decoration, solid wood composite flooring and furniture production, but there are still some technical difficulties when using veneer for decorative veneer, especially for wood-based panel substrates.

[0003] For example: in the field of solid wood composite flooring, due to the small thickness of the precious veneer on the surface, only the paint film is used to seal it, and the wear resistance and scratch resistance of the product are insufficient; Pressing or cold pressing is easy to cause problems such as plate deformation after veneering, veneer bubbling or glue penetration

At the same time, the width of veneer is generally only 30-40cm. How to achieve non-destructive, large-format splicing has always been the focus of research. Traditionally, single-sided adhesive tape is used to bond the veneer together, and then a sander is used after pressing. Sand off the tape paper, but this method will easily lead to loose splicing, large consumption of abrasive belts, and if the glue in the tape paper is left on the thin wood, it will easily affect the subsequent painting process

In addition, the decorative veneers in the prior art generally do not have flame retardant properties, and as interior decoration materials, it is very necessary to have certain flame retardant properties
