Non-slip EVA shoe sole and preparation method thereof

Abstract

The invention relates to a non-slip EVA shoe sole. The EVA shoe sole includes an A material and a B material, the A material comprises the following components, in parts by weight: 8-12 parts of standard natural rubber, 6-10 parts of styrene-butadiene rubber, 12-16 parts of cis-polybutadiene, 12-16 parts of white carbon black, 18-22 parts of EVA, and 3-7 parts of white rubber powder; and the B material includes the following components, in parts by weight: 5-9 parts of white oil, 0.1-1 part of diethylene glycol, 4-8 parts of titanium dioxide, 0.1-0.3 part of stearic acid, 1.2-1.6 parts of PEG4000, 0.8-1 part of an anti-aging agent, 0.1-0.3 part of anti-fog wax, 1.3-1.7 parts of an anti-frost agent, 2-6 parts of active zinc oxide, 0.3-0.7 part of wear-resistant oil, 0.1-0.3 part of tetramethyl thiuram monosulfide, 1.1-1.5 parts of sulfur, 0.1-0.3 part of NS powder, and 1.1-1.5 parts of an anti-yellowing accelerant. The EVA shoe sole has the advantage of lightness on the basis of slip resistance.

Description

technical field [0001] The invention relates to the technical field of shoe soles, in particular to an anti-slip EVA shoe sole and a preparation method thereof. Background technique [0002] In today's information age, more and more slip and fall accidents appear in newspapers and magazines, and it is not a small expense to settle the injury claims caused by slip and fall accidents. Simultaneously, the slipping accident seriously affects the brand image of footwear, and more and more consumers and manufacturers focus on increasing the anti-slip performance of the sole. In many cases, the reason for slipping is that there is not enough friction between the sole and the road surface interface. The most effective solution is to increase the interaction force between the sole material and the medium, thereby increasing the friction and significantly improving the anti-skid performance of the sole. Looking at the EVA soles on the market, the anti-skid performance is generally po...

Problems solved by technology

Patent CN101643560B The anti-slip EVA 3D outsole obtained by blending and foaming EVA / EPDM has obvious anti-slip effect, and the anti-slip coefficient is 0.62 for dry type and 0.40 for wet type, but it still cannot meet the needs of outdoor sports shoes

Both of these two patents use one injection molding process, one-step molding, high efficiency, but there are also major disadvantages: 1. The product stability is poor, and the product will shrink by 3% or more after passing through an oven of 10 meters or longer; 2. The injection machine requires the viscosity of the rice material to be appropriate. The more rubber components, the greater the viscosity of the material, and the injection machine may not be able to inject, which limits the amount of rubber components used and the application range of rubber and plastic foaming; 3. The one-step molding process has many demoulding machines on the surface, and the surface is smooth, so it is difficult to produce matte soles
