In summary, the following conclusions can be drawn:
1. as can be seen by combining example 1 and comparative examples 1 to 4 with Table 2, the addition of styrene-butadiene rubber and asphalt together to the raw material for shoe soles can improve the anti-slip properties of shoe soles, which may be due to: the styrene butadiene rubber is used for modifying the asphalt under the action of additives such as a vulcanizing agent and the like, the viscosity of the modified asphalt is increased, and the adhesion between the sole and the friction surface is increased, so that the anti-skid performance of the sole is improved.
2. Combining example 1 and comparative examples 5-6 with table 2, it can be seen that the co-addition of bitumen and gelatin-diethylene glycol complex to the raw material of the shoe sole improves the slip resistance of the shoe sole, probably because: the gelatin-diethylene glycol compound is introduced into the sole, so that the uniform dispersion of asphalt in styrene butadiene rubber is facilitated, the movement of rubber molecular chains is hindered, and the anti-skid performance of the sole is further improved.
3. Combining examples 1 and 4 and table 2, it can be seen that the addition of the modified waste sweet potato skin powder into the raw materials of the sole can improve the anti-slip property of the sole, and the reason may be: the modified waste sweet potato skin powder is mixed and then has stronger interface combination with the styrene butadiene rubber, so that the chain segment motion of styrene butadiene rubber molecules is limited, the wet skid resistance of the sole is improved, and meanwhile, the molecular structure of the modified waste sweet potato skin powder contains chlorine atoms with strong polarity, so that the interaction force among chains is increased, and the skid resistance of the sole is comprehensively improved.
4. Combining examples 1, 4-5, and 12 and table 2, it can be seen that adding modified waste sweet potato skin powder and potassium dihydrogen phosphate solution into the raw materials of the sole can improve the wear resistance of the sole, which may be due to: phosphate radical on the monopotassium phosphate can form ester bonds with hydroxyl on the adjacent modified waste sweet potato skin powder manufacturing macromolecules, so that the connection strength between the adjacent modified waste sweet potato skin powder manufacturing macromolecules is improved, the resistance of the sole to shearing force is further improved, the abrasion of the sole is reduced, and the abrasion resistance of the sole is improved.
5. As can be seen from the combination of examples 1 and 6 and table 2, the addition of barite powder to the raw material of the sole can improve the anti-slip property of the sole, which may be due to: partial barite particles protrude out of the surface of the sole, so that the roughness of the surface of the sole is increased, the friction between the sole and the friction surface is increased, and the anti-skid performance of the sole is improved.
6. As can be seen from the combination of examples 1, 6 to 7 and 13 and Table 2, the addition of the urethane rubber to the raw material of the shoe sole can improve the anti-slip property of the shoe sole, which may be due to the following reasons: after polyurethane rubber and butadiene styrene rubber are mixed, the elasticity of the sole is improved, when the sole is stepped on the friction surface, the sole is easy to deform and is attached to the friction surface, barite particles are embedded into the friction surface to generate an anchoring effect, and the anti-skid performance of the sole is improved.
7. As can be seen from the combination of examples 1, 7 to 8, and 13 to 15 and Table 2, the co-addition of the urethane rubber and the hydroxychlorovinyl acetate in the raw material for the shoe sole can improve the anti-slip property and wear resistance of the shoe sole, possibly due to the following reasons: the hydroxyl on the hydroxyl vinyl chloride-vinyl acetate copolymer can react with isocyanate groups in the polyurethane rubber, so that the overall density and strength of the sole are improved, and the skid resistance and the wear resistance of the sole are further improved.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
