Abstract: Air conditioning cabinet panel by the floor and decorative board by adhesive bonding, as the cabinet in recent years appearance decorative board material change and appearance structure of beautiful design, the strength of adhesive volume ratio requirement is higher and higher, and the production process is gradually turning to automation, high efficiency, low cost and low pollution, the original VHB double-sided adhesive paper can not meet the demand of the existing process. In order to find the strength of VHB double-sided adhesive material, and innovate the existing production process, through the study of the existing PUR bonding mechanism, bonding process and related performance test results, and compared with the performance of VHB adhesive paper and related process, proved that the PUR hot melt adhesive process instead of VHB adhesive paper in the air conditioning cabinet panel bonding process can improve product performance and increase efficiency.

Key words: PUR glue, Air conditioning bonding process, VHB glue paper, Automation
