Problems solved by technology

If it is EVA sandals, slippers, and indoor shoes that are in direct contact with human skin, these shoes are light, comfortable, and cost-effective.
[0003] Due to the high injection or molded foaming temperature (165-180°C) in the production process of EVA foam materials, the heat resistance of organic small molecule antibacterial agents and natural antibacterial agents is poor, and it is difficult to meet the processing requirements; silver-based inorganic antibacterial a

Abstract

The invention relates to organic polymer compound technical field, and provides a bi-color antibacterial EVA footwear and a preparation method thereof, two different colors of antibacterial EVA material grains are prepared from raw material EVA, ethylene-butene copolymer, 1, 2-polybutadiene, an antibacterial agent, chlorinated polyethylene, a foaming agent, a crosslinking agent, zinc stearate, stearic acid, a wear-resisting agent, talcum powder and a pigment by smelting, open milling and granulation, two different colors of antibacterial EVA material grains are respectively pouring into different material absorption barrels of an EVA injection machine table for once ejection to obtain the bi-color antibacterial EVA footwear, the echerichia coli and staphylococcus aureus antibacterial rates of the bi-color antibacterial EVA footwear are more than 99%, the bi-color antibacterial EVA footwear has good water-proof weather-proof lasting antibacterial properties, has the characteristics of light weight, good comprehensive performance, high production efficiency, high product qualified rate and the like, and is especially suitable for production of sandals, slippers, indoor shoes and other EVA shoes which are in direct contact with human skin, and is lightweight and comfortable, and cost-effective.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, and in particular relates to a double-color antibacterial EVA shoe and a preparation method thereof. Background technique [0002] Shoes are daily necessities that everyone wears. People wear shoes for 2 / 3 of their lives. When most people wear shoes and boots, especially in summer and after exercise, due to the sharp increase in sweat secretion and the rapid reproduction of microorganisms, a large amount of organic matter in sweat is decomposed to produce stench, which even leads to foot odor, athlete's foot, Hong Kong A series of illnesses such as pin, beriberi directly affect people's physical and mental health. The reason is that EVA is a crystalline polymer with high crystallinity, so that there are relatively few small holes that can pass through the gas, that is, the air permeability is poor, and the temperature and humidity are just suitable for easy bacterial reproduct...
