Description
The present invention relates to a non-slip shoe outsole composition which is formed separately in the shoe outsole to prevent slipping, and more particularly, rubber mixtures, additives, reinforcing agents, antioxidants, activators, silane coupling agents, softeners, vulcanizing agents and It comprises a vulcanization accelerator.
The present invention relates to a non-slip shoe outsole composition which is formed separately in the shoe outsole to prevent slipping, and more particularly, rubber mixtures, additives, reinforcing agents, antioxidants, activators, silane coupling agents, softeners, vulcanizing agents and It comprises a vulcanization accelerator.
Generally used shoe soles are divided into insoles, midsoles, and outsoles, and the outsoles are directly bonded to the ground, so they are most sensitive to the condition of the ground. It must be able to respond appropriately, especially when there is a lot of moisture on the road due to snow or rain due to climate change.
This slip prevention function is required for all outsoles of general sports shoes, but especially when the surface of the ground is irregular, such as when climbing, or when the surface of the rock, which is mainly composed of the ground such as mountains or valleys, is wet with moisture, Moisture accelerates the slip, which increases the likelihood of serious injury if the outsole lacks slip protection.
In addition, the function of slip prevention is very important even in a special workplace where the floor is always wet due to the nature of the work such as a ship.
However, existing shoe outsoles do not have adaptability to these various external environments and rely only on mechanical properties such as tensile, tear strength, and abrasion resistance. Had the disadvantage of not achieving the maximum anti-slip function.
In general, the rubber outsole for shoes is composed of raw rubber, reinforcing fillers, vulcanizing agents and vulcanization accelerators. The rubber raw materials for shoe outsoles include natural rubber (NR) and butadiene rubber (BR). , Styrene / butadiene rubber (SBR) and nitrile-butadiene rubber (NBR) are most frequently used. The vulcanizates of such rubbers have a slight difference depending on the components of the rubber, but when they are deformed by a constant external force, the rubber vulcanizates rapidly recover to their original state.
When the shoe outsole is grounded with an irregular ground, a certain level of deformation occurs on the surface of the outsole due to the load of the human body, and the appearance of rubber elasticity, which can cause a rapid recovery after the deformation occurs, eventually hinders grounding to the ground. Will be able to.
In particular, in the wet state where the ground is wet, moisture is present at the interface between the outsole and the ground, and the friction force is drastically reduced, so that the rubber elasticity of the outsole easily causes slippage, which is very likely to cause injury to the human body due to slipping accidents. There was a problem of being high.

The above-mentioned zinc oxide promotes the vulcanization of the rubber mixture, thereby shortening the vulcanization time and vulcanization. It lowers the temperature and reduces the amount of vulcanizing agent to improve the quality of butyl rubber.
American chemist C. Goodyear, the founder of the vulcanization method, first used basic carbonate as an accelerator in 1844. Since then, lime and magnesium oxide have been used, but since the vulcanization-promoting effect of aniline and thiocarbonylide was discovered in 1906, organic accelerators have been mainly used. It was used as i).
