example 1

[0045] Put the rice husk and concentration to 10 7 The cfu / mL Bacillus subtilis suspension was mixed at a mass ratio of 1:5 and put into a fermenter, and the fermenter was placed in a fermentation chamber with a relative air humidity of 70% and a temperature of 40°C, and the fermentation process was carried out by standing. After 2 weeks of fermentation, the fermentation residue was obtained by filtration and separation; the fermentation residue obtained above was put into a vacuum furnace, and carbonized at a temperature of 350 ° C for 1 h under nitrogen protection to obtain a carbonized product, and the mass ratio of the carbonized product and hydrogen-containing silicone oil was 2 After mixing, put it into a sintering furnace, sinter at a high temperature of 1800 ° C for 5 hours under the protection of argon, take out the sintered product, rinse it with 20% hydrofluoric acid for 15 minutes, and pass through a 100-mesh sieve to obtain a self-made reinforcing material; Put th...

Abstract

The invention relates to a sole material and a preparation method thereof, belonging to the technical field of shoe materials. According to the invention, eucommia ulmoides bark is soaked in alkali liquor, and filter residues of the soaked eucommia ulmoides bark are taken and are then mixed with petroleum ether, and evaporating and refluxing are conducted to obtain crude gutta-percha. Compared with natural rubber, the added auxiliary rubber, namely gutta-percha is different from the natural rubber in molecular chain configuration, wherein the natural rubber is cis-polyisoprene, and the gutta-percha is trans-polyisoprene, so the natural rubber and the gutta-percha are greatly different in properties; the natural rubber is soft and elastic, and the gutta-percha is hard rubber which is easy to crystallize; and when the sole material is stressed, an elastic chain generates molecular slippage on a rigid chain due to vulcanization crosslinking of the gutta-percha in the natural rubber and butadiene rubber, so external stress between the sole material and the ground is reduced, and thus, the internal energy consumption of the sole material is reduced, and the sole material has good wear resistance and wide application prospects.

Description

technical field [0001] The invention relates to a sole material and a preparation method thereof, belonging to the technical field of shoe materials. Background technique [0002] In recent years, with the continuous improvement of daily life, people come into contact with more and more shoes of various styles and functions. The traditional sole is mainly formed by bonding the midsole and the outsole. The outsole is often made of rubber with high anti-slip and wear resistance, while the midsole is often made of shock-absorbing and comfortable materials such as EVA. [0003] Generally, the sole material should have wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it should cooperate with the midsole. When walking and changing feet, there is a braking effect to prevent slipp...
