Problems solved by technology

At present, some soles on the market are too heavy due to the lack of formula used
If the quality of the produced sole is lighter, the related properties, such as: wear resistance, compression resistance will be reduced
And due to the limitation of the formula, the soles are prone to yellowing and frosting after being used for a long time; and some formulas contain heavy metals, lead, etc., which will cause certain harm to the human body
Due to the different ingredients and content of the formula, the production process cannot be integrally formed.
1. During the production process, the sole cannot be molded at one time, and needs to go through processing procedures such as laminating and finishing; 2. During the bonding process, the glue is easy to overflow, and the sole is prone to problems such as glue opening and glue yellowing; 3. The cut off scraps and laminating glue raw materials increase the cost

Abstract

The invention discloses a formula of a sole material. The sole made of the sole material can be formed in one piece to save cost, and the sole does not contain heavy metal and is light and breathable. The sole material comprises the following substances in percentage by weight: 1, 11.6 to 52.4 percent of ethylene vinyl acetute (EVA); 2, 7 to 13 percent of polyolefin elastomer (POE); 3, 1.4 to 2.6percent of ethylene-propylene-diene monomer; 4, 12.6 to 23.4 percent of standard rubber; 5, 12.6 to 23.4 percent of cis-polybutadiene; 6, 3.5 to 6.5 percent of butylbenzene; 7, 2.8 to 5.2 percent of talc powder; 8, 2.1 to 3.9 percent of white carbon black; 9, 2.1 to 3.9 percent of stearic acid; 10, 0.7 to 1.3 percent of modifier; 11, 1.05 to 1.95 percent of zinc oxide; 12, 1.4 to 2.6 percent of cross-linking agent; and 13, 0.35 to 0.65 percent of sulfur.

Description

technical field [0001] The invention relates to the technical field of shoe sole materials in daily life, in particular to a shoe sole material formula. Background technique [0002] Shoes are items that are often used in our daily life, and soles are an essential part of making shoes. At present, some soles on the market are too heavy due to insufficient formulas used. If the produced sole is lighter in weight, the related properties, such as wear resistance and compression resistance, will be reduced. Moreover, due to the limitation of the formula, the soles are prone to yellowing and frosting after being used for a long time; and some formulas contain heavy metals, lead, etc., which cause certain harm to the human body. Due to the different components of the formula and the different contents, the production process cannot be integrally formed. 1. During the production process, the sole cannot be molded at one time, and needs to go through processing procedures such a...
