Ice-surface dynamic anti-slip rubber sole and production method thereof

Abstract

The invention relates to a sole, and provides an ice-surface dynamic anti-slip rubber sole and a production method thereof. The ice-surface dynamic anti-slip rubber sole comprises the following compositions: natural rubber, chloroprene rubber, brominated butyl rubber, nanometer silica, a plasticizer, an anti-ageing agent, a silica activator, a silane coupling agent, hemp fiber, polyethylene wax, zinc oxide, sulfur and a sulfuration promoter. By selecting reasonably-optimized main rubber composition and compounding agents, operation is simple and practicable, and industrialized production is facilitated. The prepared ice-surface dynamic anti-slip rubber sole has extremely anti-slip effect on road interfaces of snowfield, frosted ice surface, dry ice surface and wet ice surface, is stable in comprehensive performances, guarantees a wear to not slip down because of a wet and slippery ice surface, and has extremely good market prospect.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a dynamic ice-surface anti-slip rubber shoe sole and a production method thereof. Background technique [0002] The United Kingdom's Health and Safety Executive reports that slips and trips together account for approximately one-third of non-fatal serious injuries, with a total of at least 35,000 of these injuries occurring each year across the United Kingdom (average There is one serious slip and fall accident every three minutes), accounting for more than five ten thousandths of the total population. The cost of settling a minor injury claim from a slip and fall accident can cost at least a few thousand euros, while the cost of settling a serious injury can hardly be capped. The UK cannot be the only country with these casualty rates, in fact the situation is broadly similar around the world, and China is no exception. At the same time, slip and fall accidents have seriously affected the brand...

Problems solved by technology

[0003] In many cases, the reason for slipping is that people are walking on a slippery road surface interface, and there is not enough friction between the sole of the shoe and the road surface interface, resulting in slip and fall accidents

According to existing research reports, there are three main ways to increase the friction between the sole and the road surface interface: 1. The sole pattern is non-slip. Good sole pattern design elements include a soft and tortuous structure that maximizes the contact with the ground , smooth, flat wearing surface and excellent design in all aspects, but the anti-slip effect of the anti-slip sole on wet, snowy, icy roads is not obvious

2. Add anti-slip materials to the weight part of the sole, install a number of metal anti-skid nails on the sole, embed high-hardness particles such as silicon carbide, or paste anti-slip sheets on the weight part of the sole, which can indeed increase the friction between the sole and the ice surface , but the bottom is hard and the force is uneven, which affects the comfort of the shoe. At the same time, the anti-slip material is installed or bonded on the sole, and the anti-slip material is easy to loosen, wear or even fall off.

However, butadiene rubber crystallizes rapidly at -5 degrees (see attached figure 1 ), the crystallization rate and crystallinity change with the molecular weight of the rubber. This characteristic determines that butadiene rubber is not suitable for use at -5 to -25 degrees, which limits its use as an anti-slip rubber on ice.
