AI Technical Summary

Technical Problem

The existing decorative panels suffer from uneven stress due to changes in the moisture content of the substrate during the high-temperature pressing process of melamine-impregnated paper, making them prone to deformation and requiring long curing times due to discontinuous production.

Method used

By using infrared irradiation heating combined with two-component adhesives and moisture-curing hot melt adhesives, decorative films and protective films are coated and pressed onto both sides of the substrate, enabling continuous production and avoiding problems such as changes in substrate moisture content and uneven stress caused by high-temperature pressing.

Benefits of technology

It enables continuous production of decorative panels, reduces production time, avoids deformation defects, and has less odor, better decorative effect, and color consistency.

Abstract

The present application belongs to the field of veneer processing technology, and provides a preparation method of veneer. The present application uses the way of infrared irradiation to warm the two-component adhesive to penetrate the substrate, which can effectively improve the adhesion of the substrate. At the same time, after the substrate is penetrated by the two-component adhesive, it does not need to wait for the curing of the two-component adhesive, and can directly coat the moisture-curing hot melt adhesive, press the decorative film and cover the protective film, without curing time. In addition, the veneer is attached with decorative films on both sides, which further improves the problem of uneven stress on both sides of the veneer, and achieves the same color effect on both sides. Finally, the preparation method of the present application does not use melamine paper, so that the obtained veneer has little odor, and the obtained veneer can be odor-free.
