Problems solved by technology

However, due to the low activity of the existing melamine thermosetting resin, the resin cannot be uniformly and thoroughly impregnated into the decorative paper, so that the brightness of the existing melamine veneer is not high, which cannot meet the needs of the market for high-gloss veneer

Abstract

The invention discloses a melamine veneer and a preparation method thereof, and belongs to the technical field of decorating materials. The melamine veneer is composed of a substrate and melamine impregnated paper. The melamine impregnated paper is obtained by impregnating paper in a melamine resign adhesive and processing the impregnated paper. The melamine resin adhesive has better activity as the formula thereof is determined by repeated tests. The melamine veneer has a simple processing technology, which causes the melamine resin adhesive to be more evenly and thoroughly immersed into decorating paper. The veneer formed by pressing has a plurality of advantages of the traditional melamine veneer such as high hardness, good abrasion resistance and good heat resistance, good chemical resistance, smooth and clean surface, easy maintenance and cleaning and the like, and further has the advantage of high luminance.

Description

technical field [0001] The invention discloses a melamine veneer and a preparation method thereof, belonging to the technical field of decorative materials. Background technique [0002] At present, the decorative panels used in large quantities include UV panels, baking varnish panels, and melamine veneer panels. The UV board is based on MDF, and the surface is cured by UV (Ultraviolet, ultraviolet light), so that the liquid paint becomes a solid film in a short time, and the base material and the coating film form a firm claw-shaped penetration, making the board The surface will not fall off. UV board has good brightness, bright color, strong chemical resistance, long service life, not easy to change color, easy to clean, but high cost, high requirements for mechanical equipment and process technology, and the surface is not resistant to wipe test, easy to self-crack, Self-explosion, the core material is self-heavy. Baking varnish board is a board that has been heated a...
