Boot sole and preparation method thereof

Abstract

The invention discloses a boot sole, and relates to the field of shoes. The boot sole is prepared from butyl rubber, nitrile rubber, solution polymerized styrene-butadiene rubber, C9 petroleum resin,a glass fiber, a coupling agent, a filler, an activator, a plasticizer, an anti-aging agent and a vulcanizing agent. The solution polymerized styrene-butadiene rubber has good compatibility with the butyl rubber and nitrile rubber, so that the rubber system is uniform in texture after being mixed, and the overall processability and the dispersion effect of all the components in the system are improved. The C9 petroleum resin contains some rigid molecular chain structures, so the tensile strength of the shoe sole can be improved, and the wet skid resistance of a rubber system can be improved. The glass fiber is an inorganic nonmetallic material with excellent performances, has good heat resistance and high mechanical strength, can provide good hardness and tearing strength for the sole, andcan effectively improve the wet friction coefficient of the sole. Addition of the coupling agent overcomes the defect of poor compatibility of the glass fiber and the rubber system.

Description

technical field [0001] The invention relates to the technical field of shoes, more specifically, it relates to a boot sole and a preparation method thereof. Background technique [0002] Boots are shoes with a cylindrical upper and higher than the ankle. In winter, boots are the first choice of many people because of their good thermal performance. In some areas, the ground is relatively slippery in winter, which makes the soles of the boots Anti-slip performance has certain requirements. [0003] The Chinese patent with the publication number CN107586451A discloses a cold-proof rubber sole. The rubber material for preparing the sole consists of the following components, which specifically include 50-90 parts of chlorohydrin rubber, 40-60 parts of butyl rubber, 30-50 parts of neoprene, 5-8 parts of anti-aging agent, 2-3 parts of sulfur, 3-5 parts of carbon black, 1-2 parts of zinc oxide, 8-10 parts of plasticizer, 6-8 parts of antioxidant, 3-5 parts of paraffin, 1-3 parts ...

AI Technical Summary

Problems solved by technology

[0004] The above technical solution mainly uses the cold resistance of butyl rubber to improve the cold resistance of the sole, so that the performance of the sole can meet the requirements of the low temperature environment, but for the problem of wet and slippery ground in winter, no improvement has been made on the anti-slip performance of the sole ,Room for improvement
