The invention adopts the method recorded in GB/T21396-2008 to test the bonding strength of the anti-roughening sneaker sole, and the result is shown in Table 7:
TABLE 7 bonding Strength test results for Rough-free athletic soles
As can be seen from table 7 above: (1) the middle sole and the large sole are not subjected to a roughening procedure before being attached. Generally, the bonding strength of the outsole in the sports shoe needs to be more than 25N/mm, and the risk of sole glue failure is low. From the adhesion strength test data of various middle and large sole formulas, even if the pure EVA foamed midsole is directly attached to the rubber large sole without being roughened, the final adhesion strength cannot reach 25N/mm, while the normal EVA foamed midsole cannot be pure EVA, a non-polar polymer such as POE/OBC/EPDM/SEBS is added, and the adhesion strength is lower (such as comparative example 2+ comparative example 4 or comparative example 3+ comparative example 4);
(2) in the formula of the EVA middle sole, polymers with strong polarity such as an ethylene acrylate-carbon monoxide copolymer, an ethylene-acrylic acid copolymer, an ethylene-methacrylic acid ionized resin and the like are not added, and the adhesive strength of the added ACM rubber is higher than that of the added ACM rubber in the bonding condition of the added or not added polyacrylate ACM rubber in the formula of the rubber sole, and the adhesive strength is continuously improved along with the increase of the addition amount of the ACM rubber, but the adhesive strength is higher than 25N/mm under the condition that the addition amount of the ACM rubber is higher than 10 parts;
(3) in the EVA middle sole formula, one or more polymers with strong polarity such as ethylene-carbon monoxide copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid ionized resin and the like are added, and the adhesive strength of the ethylene-acrylic acid copolymer and the ethylene-methacrylic acid ionized resin with the strongest polarity is higher than that of the ethylene-carbon monoxide copolymer with slightly weaker polarity when the polyacrylate ACM rubber (comparative example 4) is not added in the rubber sole formula, and the adhesive strength is higher when the adding amount of the polar polymer is larger;
(4) one or more polymers with strong polarity such as ethylene acid ester-carbon monoxide copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid ionized resin and the like are added in the formula of the EVA midsole, and the bonding condition of the EVA midsole and the rubber outsole formula with the addition of the ACM rubber (example 14) shows that the bonding strength is improved compared with that of the EVA midsole without the addition of the ACM rubber under the same condition, and the bonding strength reaches 30-43N/mm;
(5) compared with the situation that one or more polymers of ethyl acrylate-carbon monoxide copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid ionized resin and the like are added in the EVA foaming middle sole, the two or three compound effects are better. The compounding ratio range is as follows: 5-20 parts of an enoate-carbon monoxide copolymer, 1-15 parts of an ethylene-acrylic acid copolymer and 1-10 parts of an ethylene-methacrylic acid ionized resin;
(6) therefore, the invention is beneficial to obtaining the sole with higher bonding strength by comprehensively controlling the components of the middle sole foaming material and the rubber outsole material, and greatly reduces the risk of no need of rough bonding and no rubber cracking.

According to the invention, polymers such as the ethyl acrylate-carbon monoxide copolymer, the ethylene-acrylic acid copolymer, the ethylene-methacrylic acid ionized resin and the like are added into the insole foaming material for blending foaming, so that the polarity of the foamed insole is greatly improved, and the insole roughening procedure is saved; the polyacrylate rubber (ACM rubber) is added into the rubber outsole, so that the polarity of the rubber outsole is improved, the roughing procedure of the outsole is saved, the roughing procedure is avoided for both the insole and the outsole, the production efficiency is improved, the production cost is reduced, the damage of dust in the roughing procedure to the health of operators is also avoided, and low carbon and environmental protection are really achieved; the polarity is synchronously increased between the insole and the outsole, so that the effect of no-roughening lamination with the insole is better realized, and the problem of easy-opening glue of the insole and the outsole is solved. The experimental results show that: the bonding strength of the thickening-free sports shoe sole provided by the invention is more than or equal to 30N/cm.
