Three-dimensional woven veneer and manufacture process

Abstract

The invention relates to a three-dimensional woven veneer and a manufacture process. The three-dimensional woven veneer comprises a base veneer. The process comprises the following steps: calendaring a veneer to be attached at high temperature by a flat calendar; then taking the veneer out to be flatly placed, spraying and cooling the surface of the paper or the skin of the veneer and cycling for2-5 times; weaving the processed veneer according to a vertically and horizontally interlaced compression structure; after carrying out glue coating, cold compression and bonding on the vertically and horizontally compressed surface, hot compressing and bonding; finally calendaring at high temperature by the flat calendar; then taking the veneer to be flatly placed, spraying and cooling the surface of the three-dimensional woven veneer and cycling for 1-3 times; carrying out supplementation and drying on the surface of the base veneer and polishing by a sander so that the planeness of the surface of the base veneer reaches that of a medium density board; coating glue on the processed surface of the base veneer; attaching the processed three-dimensional woven veneer on the surface of the base veneer and placing the veneer into a cold press to compress; taking out and then placing the veneer into a hot press to compress; and trimming after the veneer is compressed.

Description

technical field [0001] The invention relates to a three-dimensional braided veneer which does not cause relative displacement and cracks between the veneer and the base plate and a manufacturing process thereof, belonging to the field of decorative plate manufacturing. Background technique [0002] CN101412230A, titled "A Flame-Retardant Decorative Veneer", the veneer is obtained by compounding flame-retardant plywood as a substrate and natural precious tree veneer. The flame-retardant plywood is produced according to the following method: put the wooden veneer into the flame retardant solution for dipping treatment, apply a mixed adhesive on the upper and lower surfaces of the veneer after the wooden veneer is dried, and form a slab after the veneer is glued, and then pass through Flame-retardant plywood products are obtained through cold pressing, hot pressing, edge trimming, sanding, cloth surface and other processes. The flame retardant is a mixture of oligomeric ammoni...

Problems solved by technology

Its shortcomings: First, the skin or paper on the veneer is prone to cracks or displacements in the four seasons, which directly affects the strength and sensory quality of the decorative board; second, the flatness is not good, and it is easy to produce paper bubbles, Partial peeling of skin bubbles and paper (skin) from the substrate
