Abstract

The invention discloses an oil-resistant anti-static-electricity rubber/EVA (ethylene-vinyl acetate copolymer) combined sole, which is formed by combining an oil-resistant anti-static-electricity rubber outer sole and an anti-static-electricity foam EVA mid sole through being brushed with anti-static-electricity glue water. The prepared sole has the advantages that on the basis of the advantages of oil resistance, anti-static-electricity performance, wear resistance and the like, the advantages of light weight of the sole, good elasticity, comfortable wearing feeling and the like are also realized, and the sole is applicable to the shoe sole worn in work occasions with oil stain and with anti-static-electricity requirements.

Description

technical field [0001] The invention relates to an oil-resistant and antistatic rubber / EVA shoe sole formula, a preparation method and application thereof. Background technique [0002] Traditional antistatic shoes are mainly due to the antistatic effect of the sole, and the sole is generally a full rubber sole with good electrical conductivity. However, due to the characteristics of hard rubber sole, heavy weight and insufficient elasticity, the wearing comfort of finished shoes is affected. However, the rubber / foam EVA soles that are currently used more and more are more and more popular among consumers due to their light weight and good elasticity. static effect. In order to make the EVA foam material have a certain conductivity, the general method is to add a special antistatic agent for EVA to make it have a certain antistatic effect. But there are following problems: one is that the addition of antistatic agent is not conducive to the mixing and foaming of EVA rubbe...
