Abstract

The invention provides a modified wormwood veneer and a preparation method thereof. The veneer contains a wormwood modified resin impregnated protective layer, wherein the content of the wormwood extract is 0.1-3%. The preparation process of the panel includes the preparation of modified melamine formaldehyde resin, the preparation of functional modifier containing wormwood extract, the preparation of glue, the preparation of the impregnated protective layer of wormwood modified resin and the post-processing steps. Through the special modified melamine Adding formaldehyde resin and the functional modifier containing wormwood extract developed by our company, combined with ultrasonic impregnation, microwave drying, hot-press drying and other treatment processes, the prepared wormwood modified veneer not only has natural antibacterial ingredients , also has excellent impact resistance, the impact strength under dry conditions reaches 53‑55KJ / m2, and is resistant to humidity, so it can be used in places with high humidity such as kitchens and bathrooms.

Description

technical field [0001] The invention belongs to the technical field of home decorative panels, and in particular relates to a modified wormwood decorative panel and a preparation method thereof. Background technique [0002] The full name of veneer is decorative veneer veneer plywood. It is a kind of surface material used for interior decoration or furniture manufacturing by cutting natural wood or technical wood into thin slices of a certain thickness, adhering to the surface of plywood, and then hot pressing. . [0003] Common veneers are divided into natural wood veneer veneers and artificial veneer veneers. The difference in appearance between artificial veneer veneer and natural wood veneer is that the texture of the former is basically a straight texture or a regular pattern; while the latter is a natural wood pattern with a natural texture pattern, relatively large variability, and irregular. Its characteristics: it not only has the beautiful pattern of wood, but al...
