Abstract

The present invention relates to the field of wood processing, in particular to a high color fastness environment-friendly gray series reconstituted decorative veneer and a manufacturing process thereof. The veneer prepared by the invention has high light fastness and color fastness. The formaldehyde emission of the veneer of the invention is less than or equal to 0.025 mg / m³; total volatile organic compounds (72 h) are less than or equal to 0.50 mg / m 2 ·h; moisture content: 4.0% to 14.0%; color fastness to light is greater than or equal to grade 4 on gray scale. Its manufacturing process comprises the following steps: S1, the log is cut into veneers by peeling or slicing; S2, the obtained peeling / slicing veneers are subjected to acetylation synergistic ultraviolet absorber pretreatment modification treatment; S3, the obtained acetyl The chemically modified veneer is pretreated before dyeing, and then preliminarily dried to a moisture content of 8-10%; then dyeing is carried out using a wood dyeing device, and the dyeing solution is an aqueous dyeing solution with high lightfastness and color fastness; S4, fixing color Light-resistant treatment; S5, processing the dyed veneer in step S4 into a reconstituted decorative veneer / material through processes such as repairing, bionic grouping, gluing with an aldehyde-free adhesive, gluing, and maintaining health.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to a high color fastness environment-friendly gray series reconstituted decorative veneer and a manufacturing process thereof. Background technique [0002] Restructured decorative veneer is made of artificial fast-growing wood, which does not destroy the microstructure and inherent properties of wood, completely retains all natural properties of natural wood such as heat insulation, insulation, temperature regulation, and humidity regulation, while overcoming the natural defects of natural tree species ( Such as knots, chromatic aberration, etc.), it is processed through the processes of log rotary cutting, veneer bleaching, dyeing, gluing, forming, curing and slicing. [0003] Italian light luxury is one of the current mainstream decoration styles. However, there are very few natural and precious tree species in the gray series. It is necessary to develop this series of restructured...
