Embodiment 1
[0024] In the present embodiment, a kind of adhesive film is made up of following components by weight: EVA15015 parts, EVA7A60H25 parts, maleic anhydride grafted SBS rubber (graft rate 7%) 21 parts, maleic anhydride polybutadiene 173114 parts 12 parts of liquid polyisobutylene, 10 parts of M80 resin, 1 part of zinc stearate, 0.2 parts of crosslinking agent BIBP, 0.1 parts of antioxidant B1004. After the above-mentioned raw materials are internally kneaded at 105°C, kneaded, and released into sheets, they are cast in a casting machine to obtain the adhesive film with a release paper as the base film, and the thickness of the adhesive film is 0.5-3mm.
[0025] After the thermoplastic rubber is mixed according to the formula requirements, it is poured, kneaded, and released. The film prepared above is covered on the thermoplastic rubber sheet through the laminating machine, and finally punched to obtain a specific shape of the film. Thermoplastic rubber backsheet. Then put the ...
Embodiment 2
[0028] In the present embodiment, the preparation method and the method of use of the adhesive film are the same as in Example 1, except that:
[0029] The composition of raw materials is different (see Table 1 for details).
[0030] The finished shoe sole prepared above had an initial bonding strength of 4.9 N / mm; after heating and aging, the bonding strength was 4.4 N / mm; after humidifying and aging, the bonding strength was 4.3 N / mm.
Embodiment 3
[0032] In the present embodiment, the preparation method and the method of use of the adhesive film are the same as in Example 1, except that:
[0033] The composition of raw materials is different (see Table 1 for details).
[0034] The initial bonding strength of the finished shoe sole prepared above is 5.3N / mm; after heating and aging, the bonding strength is 4.8N / mm; after humidifying and aging, the bonding strength is 4.2N / mm.
