Abstract

The invention provides a formula and a preparation method for an environment-friendly EVA foamed sole, and relates to the technical field of shoemaking. The formula for the environment-friendly EVA foamed sole comprises the following raw materials in parts by mass: 70-85 parts of an EVA raw material, 15-25 parts of a POE raw material, 5-15 parts of thermoplastic ethylene propylene rubber, 5-8 parts of polyvinyl acetate, 2-10 parts of octylene, 8-19 parts of ethylene, 15-26 parts of a high polymer of an amide group, 2-5 parts of dicumyl peroxide, 0.2-0.8 part of bis(tert-butylperoxyisopropyl)benzene, 0.4-2 parts of palmitic acid, 20-30 parts of silica gel and 5-13 parts of talcum powder. The sole can be well demolded during shoemaking to ensure that the sole has good quality; the sole is well foamed to save raw material cost; and a shoe has good friction performance through silica gel particles.

Description

technical field [0001] The invention relates to the technical field of shoemaking, in particular to an environmentally friendly EVA foamed shoe sole formula and a preparation method. Background technique [0002] EVA sole is a sole made of EVA material. EVA sole has high resilience, high tensile strength, high toughness, good shock resistance, cushioning performance, excellent heat preservation, cold resistance and low temperature performance. EVA sole is characterized by good softness, rubber General elasticity, good flexibility below 0°C, good transparency and surface gloss, good chemical stability, good aging resistance and ozone resistance, and non-toxic. Good blendability with fillers, good coloring and molding processability. [0003] Now in the production and processing of EVA foam soles, often because of the particularity of EVA materials, the sole materials cannot be released well after injection molding. Therefore, many shoe-making processes will use various metho...
