AI Technical Summary

Technical Problem

Existing decorative panels suffer from problems such as uneven dispersion of wear-resistant particles, weak interfacial bonding, easy detachment, and surface cracking caused by internal stress when improving wear resistance, making it difficult to achieve both high wear resistance and crack resistance.

Method used

Modified wear-resistant particles are connected to a bridging agent via borate ester bonds to form stable chemical bonds. During hot pressing, the wear-resistant particles migrate directionally to the surface layer, releasing internal stress through the dynamic reversibility of the borate ester bonds, thus forming an enriched distribution structure and a flexible buffer layer.

Benefits of technology

It significantly improves the wear resistance of the decorative panel, avoids surface cracking, and exhibits excellent crack resistance stability and good interfacial bonding strength.

Abstract

The present application belongs to the technical field of decorative panel preparation, and particularly relates to a high-wear-resistance decorative panel and a preparation process thereof. The high-wear-resistance decorative panel comprises a substrate layer, a decorative layer and a wear-resistant surface layer, and the wear-resistant surface layer contains modified wear-resistant particles. The modified wear-resistant particles are prepared by reaction of wear-resistant particles and a bridging agent, and the bridging agent is synthesized by reaction of 2-phenylbenzimidazole and bromophenylboronic acid. In the present application, the wear-resistant particles are chemically modified by the bridging agent, so that the wear-resistant particles are connected to the bridging agent through a borate ester bond, and then react with a resin matrix to form a chemical bond, thereby firmly anchoring the modified wear-resistant particles in the resin matrix. The dynamic reversible characteristics of the borate ester bond at the hot-pressing temperature enable the wear-resistant particles to directionally migrate to the stress concentration area of the surface layer during the hot-pressing process, thereby forming a surface-enriched distribution structure and significantly improving the wear resistance of the decorative panel. A flexible buffer layer is formed in the bottom layer area, thereby effectively releasing internal stress and avoiding surface cracking.
