Description

Technical Field

[0001] The invention relates to the technical field of rubber, and in particular to a styrene-butadiene rubber composite material and a preparation method and application thereof. Background Art

[0002] As the pace of life accelerates, slip and fall accidents happen from time to time, so people pay more and more attention to safe travel, and more and more businesses and consumers focus on increasing the anti-skid performance of the sole. Traditional anti-skid technology is to change the sole pattern or install anti-skid materials at the force-bearing parts of the sole, such as metal anti-skid spikes, etc. These anti-skid effects are not suitable for all occasions. The anti-skid performance can also be improved by changing the sole rubber formula and production process. Fiber fillers are a common anti-skid filler. When it is on the surface of the shoe material, it can pierce the water film or oil film, thereby increasing the surface friction. The more fibers perpendicular to the surface of the shoe material, the greater the friction; in addition, if there is a certain open hole structure on the surface of the shoe material, the surface micropores will discharge air and form negative pressure after the shoe material is subjected to force on the substrate surface. When leaving, it will form a certain adhesion with the substrate surface, thereby increasing the adhesion between the two, and then increasing the friction between the two. Summary of the invention
