Surface modification technology for EVA shoe material

Abstract

The invention discloses a surface modification technology for an EVA shoe material. The technology comprises the following steps of firstly, EVA shoe material surface treatment, wherein the outer surface of the shoe material is cleaned through an EVA special treating agent, the outer surface is softened, and drying is conducted for 10 min-20 min; secondly, primer spraying, wherein primer spraying is conducted on the EVA shoe material through a spraying device, accordingly a layer of flat primer plane is formed on the outer portion of the EVA shoe material, drying is conducted for 20 min-30 min in the environment with the temperature ranging from 60 DEG C to 70 DEG C, and the primer comprises, by weight, 100 parts of bottom host crystals, 30-80 parts of boiled oil water and 1-10 parts of binding agents; thirdly, metal spraying, wherein a metal simulating layer is sprayed to the primer through the spraying device, and drying is conducted for 5 min in the environment with the temperature ranging from 60 DEG C to 70 DEG C; and fourthly, finish coating spraying, wherein a layer of finish coating is then sprayed to the outside of the metal simulating layer through the spraying device, the modified shoe material is obtained after drying, and the finish coating comprises, by weight, 100 parts of face host crystals, 20-50 parts of hardening agents, 30-60 parts of boiled oil water and a proper amount of pigment. The surface modification technology has the beneficial effect that the decoration effect is good.

Description

technical field [0001] The invention relates to the field of surface modification of shoe materials, in particular to a surface modification process of EVA shoe materials. Background technique [0002] Shoes can generally be divided into soles and uppers, and soles can be subdivided into outsoles that directly contact the ground and play a wear-resistant role, midsoles that mainly play a shock-absorbing role, and insoles that are in direct contact with human feet. In addition to the functional roles of wear resistance and shock absorption, the outsole and midsole are also important parts of the appearance of the shoe. [0003] At present, the colors of the midsole and outsole are mainly obtained by two methods. One is to add various pigments when the shoe material itself is formed, that is, the pigment and the main components of the shoe material are mixed before the shoe material is formed. Uniform, this method is a waste of paint because most of the shoe material is not e...
