Problems solved by technology

In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the shape of the foot, and not easy to change after being shaped. Heat preservation, easy to absorb moisture, etc. The existing soles usually use protective patterns on the soles to achieve the protective effect, but after a period of use, the anti-slip patterns on the soles are easy to wear during walking, resulting in shoe wear. The anti-slip performance gradually weakens, or even disappears. In order to have a good anti-slip effect, many companies thicken the soles to produce deep anti-slip patterns. This method will increase the weight of the soles, and the feet will feel uncomfortable when wearing them. Bring a lot of burden, due to the limited depth of anti-slip lines, the improvement of anti-slip performance is not significant

Abstract

The invention discloses a preparation process of a wear-resistant antiskid sole, and relates to the technical field of shoe processing. The preparation process comprises the following steps: 1) weighing components in a certain proportion; 2) mixing rubber and polyurethane, heating, adding half of polydimethylsiloxane, and keeping the temperature to obtain a mixture A; 3) mixing an ethylene-vinyl acetate copolymer, a Phylon material and a TPR material, adding residual polydimethylsiloxane, heating, mixing, adding modified nano silicon dioxide, and carrying out heat preservation and vacuum stirring to obtain a mixture B; 4) dispersing a modifying additive and carboxymethyl cellulose into water, performing ultrasonic dispersion, and removing water to obtain a mixture C; 5) adding the mixtureA and the mixture B into a mixing mill, adding octyl epoxy stearate, mixing, adding the mixture C, mixing, adding bamboo charcoal fibers and bamboo pulp fibers, and mixing to obtain a product, 6) foaming, and 7) cutting and polishing to obtain the sole. The sole has a good wear resistant performance and antiskid performance.

Description

technical field [0001] The invention relates to the technical field of footwear processing, in particular to a preparation process for wear-resistant and non-slip soles. Background technique [0002] Shoes are one of the essential supplies in people's daily life. It provides great convenience for people's production and life. People wearing shoes can put themselves into work and production more easily, and also provide people with the opportunity to go out to participate in social activities and Participating in sports and outdoor exercise provides great convenience, it not only may play a role in keeping warm and cold, but also has a certain effect of shock absorption and foot protection. [0003] As an important part of the shoe, the sole can carry most of the functions of the shoe. The huge impact on the sole from the gravity of the human body and the external force generated by sports requires the sole to have a strong impact resistance. It must have a certain degree of...
