Problems solved by technology

This method effectively improves the anti-puncture performance, but it also brings three problems: first, the heavy weight of the metal increases the physiological load on the human body; second, the flexibility of the bottom of the boot (shoe) is poor; third, the metal layer is easy to pass Ground temperature, in high or low temperature weather, it is easy to deteriorate the temperature and humidity inside the boots (shoes), and the comfort is poor

Abstract

The invention relates to a material for making a boot sole, and concretely relates to a puncture resistant boot sole material. The puncture resistant boot sole material comprises, by weight, 20-60 parts of natural rubber, 40-20 parts of chloroprene rubber, 40-20 parts of styrene butadiene rubber, 1.2-2.0 parts of sulfur, 0.3-0.8 parts of an accelerant DM, 0.3-1.0 part of an accelerant M, 5.0-7.0 parts of zinc oxide, 1.0-2.5 parts of stearic acid, 25-35 parts of high-wear-resistance carbon black, 0.8-1.5 parts of an antioxidant D, 1.0-2.0 parts of an antioxidant 4010 and 1.5-2.5 parts of magnesium oxide. The puncture resistant boot sole material has a reasonable design, and is designed through a ternary combination method of the chloroprene rubber, the natural rubber and the styrene butadiene rubber, so the molecular chain slip and fracture phenomena of the sole material are difficult when a sole meets a sharp object, thereby the puncture resistance of the boot sole is substantially improved.

Description

technical field [0001] The invention relates to a material for manufacturing boot soles, in particular to a puncture-resistant boot sole material. Background technique [0002] With the development of protective technology, there are many types of protective shoes (boots), and various functions are becoming more and more perfect, especially in some special occasions, such as fire protection industry needs to have functions such as flame retardant, corrosion resistance, anti-skid, anti-puncture, etc., used for Military protective boots (shoes) must have protection against military poisons and high-risk chemicals, and at the same time have the ability to be flame-retardant and puncture-resistant. Regardless of whether it is used for military or civilian use, the puncture resistance of boot soles is one of the important performances of boots (shoes). If it cannot effectively resist the piercing and bursting of sharp objects, toxic and harmful substances will penetrate into the...
