Problems solved by technology

However, when ordinary EVA soles are frozen at -15°C for 24 hours, the hardness will increase by 15-20 degrees. As the hardness increases, willfulness and flexibility will be greatly reduced, resulting in sole breakage

Abstract

The invention discloses a low-temperature cold-resistant material. The low-temperature cold-resistant material comprises the following raw materials in parts by weight: 35-45 parts of thermoplastics,45-55 parts of isoprene liquid rubber, 2-4 parts of a silane coupling agent, 4-8 parts of calcium powder and 0.5-1.5 parts of stearic acid. The invention also discloses a low-temperature cold-resistant sole comprising the low-temperature cold-resistant material and a preparation process of the low-temperature cold-resistant sole. The low-temperature cold-resistant sol has the advantages that the sole has good comprehensive performance and low cost, particularly has good low-temperature cold resistance and folding resistance effects, and is suitable for manufacturing sports shoes.

Description

technical field [0001] The invention relates to the technical field of shoe soles, in particular to a low-temperature cold-resistant material, a low-temperature cold-resistant shoe sole and a preparation process thereof. Background technique [0002] Due to the rise of outdoor sports, adventure sports and other activities in recent years, as well as differences in regional conditions, in order to meet the needs of extremely harsh low-temperature environments, new requirements have been put forward for some special functions of footwear. At present, most outdoor products can only meet the needs of the general cold level. Under the extremely cold conditions, the cold resistance performance of the sole is required to be higher. However, when ordinary EVA soles are frozen at -15°C for 24 hours, the hardness will increase by 15-20 degrees, and the hardness will increase, and the willfulness and flexibility will be greatly reduced, resulting in the breakage of the soles.
