Problems solved by technology

[0002] The bonding of the traditional rubber outsole and EVA midsole is to polish the rubber outsole first, then treat the rubber outsole and EVA midsole with a treatment agent, and then use glue to bond the rubber outsole to the EVA midsole. There are many work processes, and the treatment agent and glue will pollute the environment. In addition, contact with the treatment agent and glue will cause great harm to the body. At the same time, the treatment agent and glue are prone to discoloration and failure at high temperatures, and they will fail within one day of use. , the shelf life under sealing is only 3 months, and it is easy to age, and the soles often appear to be degummed

Abstract

The invention relates to the technical field of environment-friendly materials and provides an environment-friendly material for shoes, which is high in adhesive strength, long in shelf life and low in cost, and can effectively eliminate the degumming phenomenon and avoid environment pollution. The invention also provides a preparation method of the environment-friendly material for shoes, which has a simple preparation process. The preparation method includes the steps of mixing and granulating the following ingredients in parts by weight: 100 parts of EVA (Ethylene vinyl-acetate copolymer), 0-50 parts of an EVA compatilizer, 0.1-5 parts of a peroxide vulcanizing agent and 0-10 parts of an antioxidant, processing the ingredients into powder with 20-1000 meshes, uniformly spreading the powder on a membrane with thickness of 0.01mm-0.075mm, heating the membrane to be at 90-200 DEG C and cooling to obtain the environment-friendly material for shoes. The invention also provides application of the environment-friendly material for shoes. The environment-friendly material is applied to rubber outsoles and EVA insoles to manufacture integrated soles.
