Problems solved by technology

[0006] The embodiment of the present application solves the problem that the adhesive strength of the adhesive film in the prior art decreases significantly after humidification and aging by providing the adhesive film and its preparation method and application, and realizes the aging of the adhesive film after humid heat aging (70°C, 95% humidity, 72h) after the test, the bonding strength can still reach 5N / mm, which is much higher than the bonding strength requirement of the existing composite soles, and can effectively avoid the glue-opening phenomenon of the composite soles caused by wet aging and heat aging

Embodiment 1

[0026] In this embodiment, a film is composed of the following components by weight: 35 parts of maleic anhydride grafted SBS rubber, 21 parts of chlorinated polypropylene CPP-B, 173116 parts of maleic anhydrided polybutadiene, liquid 10 parts of polyisobutylene, 16 parts of modified carbon nine resin, 1.5 parts of zinc stearate, 0.2 part of crosslinking agent BIBP, 0.1 part of antioxidant B1004. After the above-mentioned raw materials were internally mixed at 105°C, kneaded, and released into sheets, they were cast in a tape casting machine to obtain the adhesive film with a PET film as the base film, with a thickness of 3 mm.

[0027] Put the rubber film prepared above together with the rubber outsole to be vulcanized after kneading into the rubber vulcanization mold, stick the film on the side of the rubber outsole that needs to be pasted with the midsole, and vulcanize at 150°C for 90-240 seconds , then take out the rubber outsole, tear off the PET film, and let it cool na...

Embodiment 2

[0030] In the present embodiment, the preparation method and the use method of described adhesive film are identical with embodiment 1, difference is:

[0031] The composition of raw materials is different (see Table 1 for details).

[0032] The finished shoe sole prepared above has an initial bond strength of 5.5N / mm; after heating and aging, the bond strength is 5.4N / mm; after humidification and aging, the bond strength is 5.4N / mm.

Embodiment 3

[0034] In the present embodiment, the preparation method and the use method of described adhesive film are identical with embodiment 1, difference is:

[0035] The composition of raw materials is different (see Table 1 for details).

[0036] The finished product sole prepared above has an initial bond strength of 5.9N / mm; after heating and aging, the bond strength is 5.3N / mm; after humidification and aging, the bond strength is 5.1N / mm.

Abstract

The invention discloses an adhesive film, a preparation method of the adhesive film and a shoe sole comprising the adhesive film. The adhesive film is composed of the following raw materials in parts by weight: 35 parts of maleic anhydride grafted SBS rubber and 15-22 parts of chlorinated polypropylene , 15-20 parts of maleic anhydride polybutadiene, 8-12 parts of liquid polyisobutylene, 15-19 parts of modified carbon nine resin, 1.5-2 parts of zinc stearate, 0.1-0.3 parts of crosslinking agent, anti Oxygen agent 0.1-0.3 parts, the film is a cross-linked film containing a peroxide cross-linking agent, and vulcanized rubber and foam midsole in the process of heating and forming, chemical cross-linking occurs, strong adhesion, Good heat and water resistance, can effectively avoid the glue-opening phenomenon of combined soles caused by wet aging and heat aging, and enhance the brand effect of the product.

Description

technical field [0001] The invention relates to the technical field of bonding materials, in particular to an adhesive film, a preparation method of the adhesive film and a shoe sole comprising the adhesive film. Background technique [0002] With the improvement of living standards, single-component soles such as rubber soles and EVA soles cannot meet the needs of customers. Rubber soles have outstanding characteristics such as good wear resistance and good anti-slip performance, but they are heavy and inconvenient to wear; EVA The sole has good elasticity and small specific gravity, but poor wear resistance and anti-slip performance. In the prior art, the soles with superior comprehensive performance include outsoles and midsoles. The outsoles are generally rubber soles, TPR soles, etc., and the midsoles are generally EVA soles, PU soles, etc. The outsoles and midsoles are made of rubber or glue. Adhesive connection. [0003] The existing film is composed of the followin...
