Problems solved by technology

Therefore, the oil-slip resistance of rubber soles is different from the wet-slip resistance, and its properties are more complex.
[0003] The patent application number 2016110269846 discloses a rubber sole for oil-resistant safety shoes and its preparation method. According to the test of 5.3.5.3 in BS EN ISO 20345: 2011, the friction coefficient is as high as 0.5, and the anti-oil effect is remarkable, but it is not mass-produced The high-vinyl solution polystyrene-butadiene rubber has excellent sample performance, but there is no stable manufacturer and the price is expensive, so it is difficult to industrialize the rubber sole of this anti-oil safety shoe

Abstract

The invention relates to a rubber sole, and provides an anti-skid rubber sole. The anti-skid rubber sole is prepared from the following raw materials: NBR / PVC emulsion co-precipitation alloy, low-melting point polyamide, natural rubber, soluble polymerized styrene-butadiene rubber, brominated butyl rubber, white carbon black, an anti-aging agent, polyethylene glycol, a silane coupling agent, polyethylene wax, diethylene glycol, zinc oxide, stearic acid, insoluble sulfur, a vulcanization accelerator D and a vulcanization accelerator DM. The anti-skid rubber sole is vulcanized and molded in a mold of a space aluminum material, the vulcanizing temperature is 170 DEG C, the pressure is 16.5MPa-17.5MPa, and the vulcanizing time is 210-250s.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, in particular to an anti-slip rubber sole and a preparation method thereof. Background technique [0002] The friction between rubber soles and building ground and other materials is a very complex process, and the influencing factors include normal load, contact area, static contact time, sliding speed, rubber hardness, surface roughness, viscoelasticity, temperature, surface dry and wet pollution The influence of these factors on the friction coefficient is not isolated, but interrelated. Therefore, the coefficient of friction is not an inherent characteristic of the material, but a comprehensive characteristic of the material and conditions. In accordance with the requirements of BS EN ISO 20345: 2011, SATRA TM144:2011, ASTM F2913-11 and other test standards, when using the principle of horizontal drag for anti-skid test, pollutants (water, washing liquid, oil, etc.) are on ...
