Problems solved by technology

[0002] According to the needs of the application, there are many different proportioning schemes for the shoe edge rubber. The most commonly used one is to use diethylene glycol or triethanolamine to activate the rubber. However, the vulcanized rubber obtained in this way has a low snow whiteness, low gloss, and is matte. 1. The stiffness of the semi-finished rubber material is unstable, the shape retention of the pattern is poor, the traces of the sole are exposed, it is easy to cause compression deformation, and the appearance of the product is not clear; and the yellowing resistance under the sun lamp B method reaches 3 to 5 grades, while Those below grade 3 must use high-priced materials such as anti-yellowing accelerators and ultraviolet light absorbers; the size of the shoe film is unstable, it is difficult to ensure the stability of the appearance, and the product grade is low; the physical properties of this vulcanized rubber are: tensile strength 7 ~ 9Mpa, elongation at break 300 ~ 400%, after the rubber shoes are bent 5,000 times, cracks begin to appear on the surface of the rubber shoes film, and the bending resistance is poor
The above properties have caused the existing vulcanized rubber to have many deficiencies when used as shoe edge rubber, and it is difficult to meet the needs of use.
