Description

Technical Field

[0001] The invention relates to the technical field of soles, and in particular to a sole and a preparation method thereof. Background Art

[0002] For rubber used in shoes, good anti-skid property is one of the basic functions that rubber products for soles should have, and it is also an important indicator to measure the quality of shoes. The anti-skid property of the sole refers to the anti-skid effect or grip of the sole on the ground. The quality of the anti-skid property is directly related to the safety of the shoes when worn. If the anti-skid property of the sole is not good, it is easy to slip and fall when walking on wet and icy roads. In most parts of northern my country, the temperature is low in winter, and the road surface is prone to water accumulation and ice, making it easier for people to slip when walking on it.
