[0059] Azodicarbonamide: 2.2%;

[0060] Masterbatch: 5%.

[0061] 2, the manufacture method of environmental protection EVA foam shoe material EVA foam shoe material comprises the following steps:

[0062] 1) Mix the bis-(tert-butylperoxyisopropyl)benzene and azodicarbonamide for later use, and pour the remaining raw materials into the mixer for the first stage of mixing to make the materials evenly mixed. , when the temperature reaches 105~110℃, then add the mixture of bis-(tert-butylperoxyisopropyl)benzene and azodicarbonamide, start the mixer again to carry out the sec...

Embodiment 2

[0071] Example 2: Adjusting EVA7470M, POE8150, bio-based plastics, OBC on the basis of Example 1 S The dosage, its raw material formula is as follows:

[0072] Ethylene-vinyl acetate copolymer: 40%;

[0073] Bio-based plastics: 20%;

[0074] Ethylene-octene copolymer: 15%;

[0075] Polyolefin block copolymer: 5%;

Abstract

The invention relates to environment-friendly EVA foaming shoe material and a manufacturing method thereof. The EVA foaming shoe material comprises ethylene-vinyl acetate polymer, bio-based plastics, ethylene-octene polymer, polyolefin block copolymer, talcum powder, stearic acid, zinc stearate, zinc oxide, di-(tert-butyl peroxy isopropyl)benzene, azobisformamide and color master batch. The method includes: all raw materials except the di-(tert-butyl peroxy isopropyl)benzene and the azobisformamide are mixed and subjected to first-stage banburying, the mixture of the di-(tert-butyl peroxy isopropyl)benzene and the azobisformamide is added when the temperature reaches 105-110 DEG C, first-stage banburying is performed, mixture after the banburying is obtained until the temperature rises to 112-115 DEG C, the mixture is thinned to obtain sheets, granulation is performed, the materials after granulation is injected into shoe dies after standing, and sulfur adding and forming are performed; QC inspection, surface processing, physical property spot checking and packaging and storage are performed.

Description

technical field [0001] The invention relates to an EVA foamed shoe material, in particular to an environment-friendly EVA foamed shoe material suitable for children and teenagers and a manufacturing method thereof. Background technique [0002] my country is a big producer of footwear, and there are all kinds of shoes. However, the shoe materials for children and teenagers are relatively single and scarce, while the shoe materials used by adults can be described as rich and colorful. Especially in European and American countries in the formulation of standards for harmful substances in shoe materials, the standards for children's shoes are far higher than the standards for adult shoes, while my country is not only relatively lagging behind in the formulation of footwear standards, but also has almost no standards for children's shoes, let alone Not on the control of hazardous substances. Children and adolescents are our future. Paying attention to children and adolescents sh...
