A device for testing the bonding strength of composite layers of decorative panels

Abstract

The invention discloses a device for testing the bonding strength of a composite layer of a decorative board, which relates to the technical field of strength detection of a decorative board, comprising a fixing device, a power device, a compensation device and a positioning device, the fixing device is connected to the power device, and the power device and the compensation device are driven Connection, connection between compensation device and fixing device, connection between positioning device and fixing device, transmission connection between power device and positioning device, fixing device includes stage and mounting seat, stage and mounting seat are provided with brackets, stage and bracket are tightly connected Fixed connection, the mounting seat and the bracket are connected flexibly, there are several clamping seats on the underside of the mounting seat, there are wedge grooves on the clamping seats, the wedge grooves face the upper edge of the decorative board, and there are several card slots on the stage, and the card slots face the decoration The edge line of the lower layer of the board, the card groove restricts the lower layer of the decorative board, the clip seat restricts the upper layer of the decorative board through the wedge groove, and the limit through the edge line to prevent damage to the surface of the decorative board.

Description

technical field [0001] The invention relates to the technical field of strength detection of a composite layer of a decorative board, in particular to a device for testing the bonding strength of a composite layer of a decorative board. Background technique [0002] With the continuous development of the construction industry, the requirements for composite laminates are becoming more and more diverse. Decorative panels are one of the new types of panels in the construction industry. By adding decorative panels to the wall, the overall aesthetics of the building can be improved, making the building more attractive. welcome. [0003] However, decorative boards are often made of multi-layer boards. Due to the high temperature of the melt glue, it has a certain fluidity, and the glue application cannot be guaranteed evenly. Therefore, when gluing large boards, it is easy to make the composite layer of the decorative board empty. , resulting in poor adhesion, in the long-term u...

Problems solved by technology

[0003] However, decorative boards are often made of multi-layer boards. Due to the high temperature of the melt glue, it has certain fluidity and cannot guarantee uniform glue application. Therefore, when large-scale boards are glued together, it is easy to cause voids in the composite layer of the decorative board. , resulting in insufficient bonding. In the long-term use process, due to changes in air temperature and humidity, it is easy to cause degumming and affect the service life

[0004] The adhesive performance of the composite layer of the decorative board now mostly adopts the impact test, but many decorative boards are built-in design, and the impact load is less in the process of use, so the bond strength test through the impact is likely to lead to inaccurate detection. In addition , when the decorative panel is manufactured, the impact test will cause damage to the decorative panel

The surface of the decorative board is designed with a pattern, which will also damage the surface pattern during the clamping process and affect the product quality
