[0045] 2. The peel strength between the Magic Tape hook surface layer and the Magic Tape hair surface layer was tested according to the method of GB / T 23315-2009 “Buckle bag”, and the test results were the average values of 4 samples; the test results are shown in Table 2 below.

[0046] Table 1 Performance test results of waterproofing membranes in Examples 4-10 and Comparative Examples 1-3

[0047] Compared with Comparative Examples 1-3, the peel strength between the membranes and the peel strength between the membranes and the post-cast concrete of Examples 4-6 are higher than those of Comparative Examples 1-3, which shows that by adding silane coupling agent KH-550 and calcium 5-methylphenol-2-sulfonate to the filler of the adhesive waterproofing layer, the peel strength between the membranes and the peel strength between the membranes and the post-cast concrete can be improved.

[0048] Compared with examples 4 and 7, the roll-to-roll peel strength and the roll-to-post-cast-concrete peel strength of examples 8-10 are higher than those of examples 4 and 7, which indicates that the addition of the butyl rubber composed of the first butyl rubber and the second butyl rubber to the adhesive waterproof layer can improve the roll-to-roll peel strength and the roll-to-post-cast-concrete peel strength of the adhesive waterproof layer.
