Patent CN 101643560 B The anti-slip EVA 3D outsole obtained by blending and foaming EVA and 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
These two patents both use one-time injection molding process, one-step molding, high efficiency, but there are also major disadvantages: 1. The product has poor stability. After passing through an oven of 10 meters or longer, the pr

Embodiment 1
[0046]In the present embodiment, antiskid EVA sole is made up of following components by weight:
[0047] 20 parts of EVA 5110J, 30 parts of EVA 7470M, 10 parts of liquid rubber, 8 parts of thermoplastic elastomer, 4.5 parts of ethylene-ethyl acrylate copolymer (EEA), 2.5 parts of chlorinated polyethylene, superfine powder of hemp stem core 2 1.2 parts of AC foaming agent, 1.2 parts of crosslinking agent BIBP, 1.5 parts of nano zinc oxide, 0.8 parts of zinc stearate, 0.8 parts of stearic acid, 2 parts of anti-wear agent AG209, and 8 parts of inorganic filler.
[0048] First mix other raw materials except the cross-linking agent BIBP and AC foaming agent for banburying, adjust the banburying temperature to 90-100°C, keep it for 5 minutes, then add the cross-linking agent BIBP and AC foaming agent, continue The banburying is heated up, and the discharge temperature is 105-115°C. After the banburying is completed, the milling and granulation are carried out to obtain non-slip EVA...

Abstract
The invention belongs to the technical field of an organic high-molecular compound, and particularly relates to an antiskid EVA sole and a preparation method thereof. The antiskid EVA sole is prepared from the following raw materials: EVA, liquid rubber, a thermoplastic elastomer, a tackifier, chlorinated polyethylene, hemp stem core superfine powder, an AC foaming agent, a cross-linking agent, nanozinc oxide, zinc stearate, stearic acid, a wear-resistant agent and inorganic fillers. The preparation method comprises the following steps: banbury-mixing and open-milling the raw materials, pelletizing to obtain antiskid EVA particles, and then performing heating foaming and secondary oil-pressure forming to the antiskid EVA particles, to obtain the antiskid EVA sole. The antiskid EVA sole has the characteristics of being light in mass, high in antiskid property, good in handfeel and size stability and the like, as well as excellent in tensile strength and tearing strength, is especially suitable for application on aspects of various shoe accessories, sole materials and the like, and is good in comfortableness and long in service life.
Description
technical field [0001] The invention belongs to the technical field of organic polymer compounds, and in particular relates 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-s...
