Abstract

The invention discloses an EVA shoe sole and a preparation method thereof. The EVA shoe sole is prepared from, by weight, 60-70 parts of EVA, 8-10 parts of OBC, 12-15 parts of POE, 1-2 parts of an ACfoaming agent, 1-2 parts of a cross-linking agent and 2-3 parts of an activator. The OBC has good heat resistance, high elasticity and good processability, and can provide excellent resilience for anEVA foaming system, so that the EVA sole has high elasticity and is not prone to being compacted. By adding the POE, the resilience of the EVA sole can be further improved, the surface crystallizationrate of the material can be reduced, the problem that the surface of a traditional EVA foamed shoe material is prone to wrinkling is solved, and the attractiveness of the product is improved. Besides, OBC molecules and POE molecules inevitably form entanglement in a three-dimensional space, and the entanglement can limit movement of macromolecular chain segments like chemical crosslinking, so that the EVA sole is further not prone to being compacted, the surface of the EVA sole is not prone to wrinkling, and the use performance and the attractive performance are guaranteed.

Description

technical field

[0001] The invention relates to the technical field of shoes, more specifically, it relates to an EVA sole and a preparation method thereof. Background technique

[0002] Ethylene-vinyl acetate copolymer (EVA) foam soles are widely used in the production of various shoe soles because of their light weight, good flexibility, comfortable wearing, non-wrinkle resistance, and good elasticity.

[0003] The Chinese patent with the publication number CN103242584B discloses a wear-resistant EVA shoe sole material. In terms of mass percentage, the shoe sole material is composed of the following components: EVA 65-85%, wear-resistant agent 5-10%, light stabilizer 0.5- 5%, particle size ≤ 200nm inorganic filler 5-15%, foaming agent 1-3%, crosslinking agent 0.5-2%, dispersing lubricant 1-3%, among which, the anti-wear agent is made of ethylene-vinyl acetate Composed of copolymer and ultra-high molecular weight silicone polymer, the mass percentage of each component is: ...
