Problems solved by technology

Related studies have shown that under the same contact area and the same normal load, the friction coefficient of the wet surface is greater than that of the glycerin lubricated surface, because the rubber and the test interface cause a strong adhesion effect and negative friction under the action of medium water. Pressure effect, while glycerin itself has a high viscosity and also has a lubricating effect. The adhesion and negative pressure effects are not obvious, and the properties are more complicated.
Moreover, in the case of a wet surface (water), the friction coefficient of the rubber and the test interface increases with the increase of the effective contact area, and in the case of glycerin lubricated surface, the friction coefficient of the rubber and the test interface increases with the effective contact area As the area increases, there is a tendency to decrease, so the anti-oil performance of rubber soles is different from the anti-wet performance, and its properties are more complex.

Abstract

The invention relates to a rubber sole and provides a slippery resistant safe shoe rubber sole and a preparation method thereof. The provided rubber sole has a strong performance on resisting slipping. The friction coefficient is not less than 0.45 and is obvious higher than the slippery resistant requirements (heelpiece 0.13, smoothness 0.18) of international standard BS EN ISO 20345:2011 personal protective equipment safe shoes. The rubber sole is composed of the following raw materials: high vinyl solution polymerized styrene-butadiene rubber, high acrylonitrile nitrile rubber, NBR / PVC emulsion co-precipitated alloy, white carbon black, an anti-aging agent, polyethylene glycol, a silane coupling agent, polyethylene wax, yellow resin, diglycol, zinc oxide, insoluble sulfur, and a vulcanization promoter.

Description

technical field [0001] The invention belongs to the technical field of organic polymer compounds, and in particular relates to a rubber sole of oil-resistant safety shoes and a preparation method thereof. Background technique [0002] According to the requirements of the international standard BS EN ISO 20345: 2011 personal protective equipment safety shoes, the tear strength, wear resistance and folding resistance of the safety shoe soles are mandatory requirements. At the same time, safety shoes involve many workplaces and the working environment is complex and changeable , there are also some special requirements, such as the requirements of 5.3.5.3 anti-slip performance of the sole, to prevent accidental slipping and falling accidents of the staff. At present, most of the safety shoes on the market can meet the minimum anti-skid requirements of BS EN ISO 20345: 2011 (heel 0.13 smooth 0.18), but safety shoes used in special industries such as oil factories, petrochemical ...
