The invention relates to the field of foaming shoes in hospitals, scientific research laboratories and food industries, in particular to high-temperature-resistant EVA foaming shoes and a preparation method thereof.
Background
Hospitals, scientific research laboratories and food industries have certain requirements on wearing of workers, and clothes and shoes can be used after being disinfected. Particularly in the medical field, doctors need to stand frequently for operations, feet are easy to sweat after being stressed for a long time, sweat is secreted by sweat glands, contains salt, amide and trace elements, the pH value of the sweat is between 4.2 and 7.5, and the humidity and the pH value in the shoes provide an environment suitable for fungi to grow, so the shoes need to be disinfected after being used.
Currently, high-temperature sterilization or Ultraviolet (UVC) sterilization is generally adopted, however, each microorganism has a specific uv-ray killing dose standard, and ultraviolet rays can only be transmitted along a straight line and have weak penetrating power, so that the sterilization effect by using ultraviolet rays (UVC) is not satisfactory. In high-temperature sterilization, the temperature is generally about 100 ℃, fungi can be killed after the temperature lasts for 20 minutes, however, the traditional shoes can resist the high temperature of 80 ℃ at most, and therefore, the shoes which can resist the high temperature are urgently needed.
