High-weather-resisting type green recombined decorative veneer and preparation method thereof

Abstract

The invention relates to a high-weather-resisting type green recombined decorative veneer and a preparation method thereof. The high-weather-resisting type green recombined decorative veneer is prepared from a transparent abrasion-resisting adhesive film paper layer, a high-color-fastness recombined decorative veneer layer and a flexible enhanced material layer in sequence from top to bottom. Thepreparation method comprises the following steps: (1) manufacturing the high-color-fastness recombined decorative veneer layer: taking a rotatably-cut or sliced veneer as a main raw material; processing through procedures of dyeing by a high-color-fastness dyestuff, carrying out bionic assembling, coating an environment-friendly toughening adhesive, gluing and curing, so as to obtain a recombineddecorative limber batten; (2) coating one face of a flexible enhanced material with an environment-friendly formaldehyde-free adhesive and then compounding the flexible enhanced material on the back surface of the high-color-fastness recombined decorative veneer layer prepared by step (1), and carrying out hot pressing; (3) manufacturing the transparent abrasion-resisting adhesive film paper layer; (4) compounding the transparent abrasion-resisting adhesive film paper layer prepared by step (3) on the surface of the compound veneer prepared by step (2) and conveying the compound veneer into ahot pressing machine; carrying out hot pressing to obtain the high-weather-resisting type green recombined decorative veneer.

Description

technical field [0001] The invention relates to a highly weather-resistant green recombined decorative veneer and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] Recombined decorative veneer (commonly known as: technical wood veneer) is a veneer made of rotary cut or sliced ​​veneer as the main raw material, which is made of veneer coloring, lamination, and gluing to form a wooden square, and then sliced. . After years of development, technological wood has continuously penetrated into various fields of human life from the initial decorative veneer to floors, composite floors, fireproof boards, various handicrafts, daily necessities and cultural and sports products. However, the urea-formaldehyde resin used in the production of recombined decorative veneer has a high molar ratio, and there is a problem of high formaldehyde emission; and during storage and use, the recombined decorative veneer is exposed t...
