The test results were as follows:
the above results were analyzed to find that:
1. when 3, 4-epoxy cyclohexyl methyl-3, 4-epoxy cyclohexyl formate is not selected as epoxy resin in the acrylate adhesive, the retention rate of the peeling strength after the whole-process aging is only 50%, the strength is at a lower level and is easy to crack, and meanwhile, when the using amount of the 3, 4-epoxy cyclohexyl methyl-3, 4-epoxy cyclohexyl formate is reduced, the retention rate of the peeling strength after the whole-process aging is gradually reduced, namely the 3, 4-epoxy cyclohexyl methyl-3, 4-epoxy cyclohexyl formate can effectively improve the peeling strength of the product after the whole-process aging, and plays a main role in maintaining the peeling strength after the whole-process aging;
2. the liquid nitrile rubber has a relatively obvious effect on the improvement of normal-temperature peeling, the retention rate of the peeling strength after the whole process is aged is gradually reduced along with the reduction of the using amount of the liquid nitrile rubber, but the influence on the reduction range is less than that of 3, 4-epoxy cyclohexyl methyl-3, 4-epoxy cyclohexyl formate, and the liquid nitrile rubber and the 3, 4-epoxy cyclohexyl methyl-3, 4-epoxy cyclohexyl formate synergistically improve the retention of the peeling strength after the whole process is aged.
