The double-sided adhesive tape is widely applied to the design and production of the sticky hook as a simple and efficient anchoring material. The double-sided adhesive layer on the back of the sticky hook plays a key role in the use of the sticky hook, and the weight bearing effect of the sticky hook is directly determined by the cohesive strength of the adhesive layer. With the progress of society and science and the improvement of living standard, the application of the sticky hook is wider, and simultaneously, higher requirements on the load bearing performance of the sticky hook are provided.
At present, common adhesive hook back glue on the market is generally made of acrylic acid materials or rubber materials, and the cohesive strength of common adhesives hardly meets the high load requirement of hooks. It is therefore common for sticky hooks to fall off after a period of use or for sticky hooks to be unable to withstand heavier items. This brings inconvenience to people's production and life. Usually, sticky hook production enterprises adopt a method of increasing the gum area to improve the weight hanging effect, but the method easily causes material waste and is difficult to meet the use scenes that some sticking positions are small and the load is high.
