Problems solved by technology

The disadvantage of this invention is that the compatibility between alloy and rubber is not good, and the preparation process is complicated, and the anti-skid effect needs to be further improved
[0007] In summary, the natural rubber materials used for sports shoe soles in the prior art have certain anti-skid performance, but the anti-skid performance cannot meet the needs of high-grade sports shoe sole materials, and existing technologies such as adding inorganic fillers The modified method has poor filler dispersion and unsatisfactory effect. Therefore, it is of great significance to develop a natural rubber material for sports shoe soles with excellent anti-skid performance.

Abstract

The invention belongs to the technical field of sneaker materials, and provides an anti-skid natural rubber material for sneaker soles and a preparation method thereof. The method comprises the following steps: modifying precipitated white carbon black filler with phenyl isocyanate, modifying graphene oxide filler with carboxy nitrile rubber, adding C5 petroleum resin into crude rubber of naturalrubber, and performing mixing, mill-running and vulcanizing to prepare the anti-skid natural rubber material. Compared with a traditional method, the anti-skid natural rubber material has the advantages that the inorganic filler has good dispersibility and cannot be easily agglomerated; the rubber material has relatively high dry friction coefficient and wet friction coefficient, the anti-skid performance is remarkably improved, and the abrasion resistance is improved to a certain extent, so that the anti-skid natural rubber material can be used as a sole material of high-grade sneakers.

Description

technical field [0001] The invention belongs to the technical field of sports shoe materials and provides a non-slip natural rubber material used for sports shoe soles and a preparation method. Background technique [0002] With the in-depth development of national fitness activities and people's increasing attention to sports, sports shoes are indispensable equipment for people's competition and daily exercise. Sports shoes with good performance are not only comfortable, but also can enhance people's interest in actively participating in fitness activities. It can also reduce physical damage caused by slip and fall accidents. Among them, the common characteristics of sole materials should be wear-resistant, water-resistant, oil-resistant, heat-resistant, pressure-resistant, impact-resistant, good elasticity, easy to fit the foot shape, not easy to change shape after setting, heat preservation, easy to absorb moisture, etc., and at the same time have anti-slip And the funct...
