Problems solved by technology

[0002] Shoes are commonly used in people's daily life. Traditional shoes are composed of two parts: the sole and the upper. In the traditional production process, the upper and the sole are made separately, and then the upper and the sole are bonded together by glue. The connection is completed together. The traditional connection method is easy to lose adhesion during use, and the separation between the upper and the sole makes the shoes unable to use normally.
[0003] Most of the traditional shoes are made of plastic material, but the plastic material has no cushioning effect. When people wear plastic material shoes, if they accidentally kick the hardware, sometimes, the shoes without cushioning effect will be harmful to the feet of the human body. Harmful, plastic is a kind of material that is difficult to degrade, and it can exist for decades to hundreds of years, resulting in poor environmental protection of shoes, and shoes made of plastic are easily damaged when impacted, resulting in reduced reliability of use, and The production process of shoes is relatively complicated and the production cost is high, and this is the main shortcoming of traditional technology

Embodiment 1

[0045] The manufacturing process of EVA rubber material shoes: Add EVA raw materials and place them in the internal mixer for mixing, then add color fillers, crosslinking agents, foaming agents, and foaming aids for mixing. The filler is Talcum, and the crosslinking agent is DCP, The foaming agent is AC, the foaming aid is ZnO, the ratio between EVA raw material, filler Talcum, crosslinking agent DCP, foaming agent AC, and foaming aid AC is 20:2:2:1:1, dense The temperature of the mill is 50° C., and the mixing time is 20 minutes. After the mixing is uniform, the material is discharged to obtain the EVA rubber composite material.

[0046] The color filler can be a color filler of any color.

[0047] The EVA rubber composite material to be granulated is automatically fed into the feeder through the automatic feeder, and the feeder sends the material into the main machine of the plastic granulator evenly and orderly, and the main machine of the plastic granulator realizes granul...

technical field [0001] The invention relates to the technical field of shoes, in particular to a shoe made of EVA rubber and a production process thereof. Background technique [0002] Shoes are commonly used in people's daily life. Traditional shoes are composed of two parts: the sole and the upper. In the traditional production process, the upper and the sole are made separately, and then the upper and the sole are bonded together by glue. The connection is completed together. The traditional connection method tends to lose its adhesion during use, and the separation between the upper and the sole makes the shoes unable to be used normally. [0003] Most of the traditional shoes are made of plastic material, but the plastic material has no cushioning effect. When people wear plastic material shoes, if they accidentally kick the hardware, sometimes, the shoes without cushioning effect will be harmful to the feet of the human body.
