Description

Technical Field

[0001] This utility model relates to the field of customized furniture and interior decoration technology, specifically to a seamless splicing structure of paint-free boards. Background Technology

[0002] Solid wood eco-board, also known as melamine board or antibacterial board, is an environmentally friendly board made from machine-assembled Indonesian Malacca or fir plywood as the base material, using a veneer process. Its structure consists of a surface paper, a cover paper, a base paper, and a decorative paper. The surface is formed using a melamine-faced paper hot-pressing process, and it is mainly used in custom furniture and interior decoration.

[0003] Traditional right-angle splicing typically uses U-shaped or L-shaped PVC / ABS edge banding strips for covering and sealing the edges. These strips are primarily adhered to the end face and the front / back surface of the panel using hot melt adhesive. The bonding area is limited, and the end face adhesion is often weak. The edge banding strip is prone to lifting and detachment due to aging of the hot melt adhesive or external force. The edge banding strip is usually thicker than the surface layer, creating a "step-like" appearance. The splicing point becomes the weakest link in the structure, easily cracking and delaminating during handling, heavy loads, frequent opening and closing of cabinet doors and drawers, or changes in ambient temperature and humidity. Edge banding installation is cumbersome: it requires a hot melt glue gun and an edge banding machine, and precise control of temperature, pressure, and speed is essential; otherwise, it can lead to poor adhesion, glue overflow, and burns to the surface. After edge banding, manual or machine trimming is required to remove excess strip and chamfer the edges, resulting in numerous steps and a high risk of defects. Utility Model Content
