Problems solved by technology

The soles of the mountaineering shoes provided by the above-mentioned patents are all made of metal materials (metal convex teeth / metal studs, or mountaineering spikes). Although the anti-slip properties of the soles are improved and the safety of the mountaineering process is ensured, the mountaineering shoes are only suitable for mountaineering. worn from time to time, and the elasticity of the sole is low, resulting in a decrease in comfort

Abstract

The invention discloses a sole material for sports shoes for body-building and mountaineering and a preparation method thereof. According to a formula, the sole material comprises the following components in percentage by mass: 25-30% of natural rubber, 25-35% of styrene butadiene rubber, 1-3% of short fiber, 8-15% of a carbon black, 10-12% of SiO2, 2-2.5% of a stearic acid (SA), 3-5% of zinc oxide (ZnO), 2-3% of disilane tetrasulfide (Si-69) and 3-6% of sulfur (S). After the components are mixed, the obtained mixture is mixed into a rubber compound by using an internal mixer for short fibers and rubber, then the rubber compound is fed by using an open mill or a calender, and the obtained object is extruded by using a pin cold-feed extruder with a short fiber oriented head, and finally, the obtained object is extruded by using a pin cold-feed extruder with a short fiber oriented head, and finally, the extruded product is vulcanized in a sole die, thereby obtaining a sole product for sports shoes for body-building and mountaineering. By using the sole material, soles have good abrasion resistance and puncture resistance while having good elasticity, so that the comfortableness and security of body-building and mountaineering exercises are improved, and the service life of shoes is prolonged to a certain extent, therefore, the sole material has a broad market application prospect.

Description

technical field [0001] The invention relates to a sports shoe sole material for fitness and mountaineering and a preparation method thereof, in particular to a composite material containing short fiber rubber which is used for the sole of mountain climbing shoes and improves the elasticity, wear resistance and anti-skid property of the sole and The method of preparation of the material. Background technique [0002] In modern society, people generally pay more attention to the importance of physical exercise. Many people regard running and mountaineering (non-professional mountaineering) as their first choice for fitness. As far as mountaineering is concerned, in addition to mountaineering and fitness, people also pay great attention to the comfort and safety of the mountaineering process, which depends on the performance of the sole. Patent CN102366185 discloses a kind of anti-fatigue mountaineering shoes, the sole of which is made of polyurethane resin material, and meta...
