Embodiment 1

[0066] The formula of EVA anti-deformation sole is as shown in table 1.

[0067] The formula of table 1 EVA anti-deformation sole

[0068]

[0069] 1. Prepare the EVA foam bottom layer.

[0070] 1.1 Mix ethylene vinyl acetate copolymer (EVA 7350M), polyolefin elastomer (POE 8105), talcum powder, stearic acid, zinc stearate and zinc oxide as the raw material of EVA foam bottom layer to form EVA foam bottom layer One ingredient.

[0071] 1.2 Put the first ingredient of the EVA foam bottom layer into the internal mixer for mixing. When the first ingredient of the EVA foam bottom layer is mixed to 70±2°C, lift the weight for the first time to sweep the dust, and continue mixing to 90±2°C , lift the weight hammer for the second time to sweep the ash, continue mixing to 120±2°C, lift the weight hammer for the third time, and obtain the first ingredient of the EVA foam bottom layer after mixing.

[0072] 1.3 Mix the raw material crosslinking agent and foaming agent of the EVA f...

Abstract

The invention provides an anti-deformation EVA shoe sole and a preparation method thereof, and an arch-protecting anti-deformation sneaker. The anti-deformation EVA shoe sole comprises an EVA foamed bottom layer and an EVA foamed top layer bonded with the EVA foamed bottom layer. The EVA foamed top layer is prepared from the following raw materials in parts by weight: 82.5 to 87.5 parts of an ethylene vinyl acetate copolymer, 12.5 to 17.5 parts of polyolefin elastomer, 8 to 12 parts of talcum powder, 0.4 to 0.6 part of stearic acid, 0.8 to 1.2 parts of zinc stearate, 1 to 2 parts of zinc oxide, 0.2 to 0.8 part of a cross-linking agent and 2.5 to 3.5 parts of a foaming agent. The EVA foamed bottom layer is prepared from the following raw materials in parts by weight: 82.5 to 87.5 parts of the ethylene vinyl acetate copolymer, 22.5 to 27.5 parts of polyolefin elastomer, 8 to 12 parts of talcum powder, 0.4 to 0.6 part of stearic acid, 0.8 to 1.2 parts of zinc stearate, 1 to 2 parts of zinc oxide, 0.2 to 0.8 part of a cross-linking agent and 2.5 to 3.5 parts of a foaming agent. The anti-deformation EVA shoe sole can more effectively support the foot arch and prevent deformation damage.

Description

technical field [0001] The invention belongs to the technical field of shoe materials, and in particular relates to an EVA anti-deformation sole, a preparation method and arch-protecting anti-deformation sports shoes. Background technique [0002] Sports have become an important part of people's lives, so sports shoes should not only be comfortable, light and durable, but also safe to wear. For the purpose of improving athletes' performance and people's wearing comfort and lightness, sports shoes are required to be as light as possible and to maintain excellent mechanical properties. [0003] Ethylene vinyl acetate copolymer (EVA) has good flexibility, toughness and processability, and its foaming material is usually used as the sole material of sports shoes. For example, the EVA foam material is directly molded into the sole of a sports shoe or the midsole of a shoe. However, the soles of such sports shoes generally have the problem that the soles of the arches of the fee...
