Description

General-purpose nonslip pad for shoes

The present invention relates to a general non-slip pad to be worn on a shoe, as well as safety shoes worn in the industrial field, as well as having a structure that can be worn on the bottom of the general shoe, the sole is worn out to prevent the slip function The present invention relates to a general non-slip pad that is worn on a shoe that can be easily worn where there is a risk of slipping due to water or oil due to specialization or general shoes.

The sole of the shoe is used for the purpose of preventing slipping and at the same time to alleviate the impact of contact with the floor. In particular, the specialization of safety shoes used in the industrial field was one of the main purposes to prevent slipping on the floor of water or oil.

In general, the sole for preventing slip is a structure that forms a plurality of protrusions on the surface in contact with the bottom surface, which is formed by artificially roughening the surface in the mold, so that the mold production is long and the production cost is increased. Rather, the irregularities formed on the sole surface during product molding are lost by wear in use, and thus the anti-slip function is lost.

In addition, there was a non-slip structure such as forming a plurality of protrusions on the bottom of the sole, or installing a spike to press the bottom surface.

In addition, the sole of the sole is made of a non-slip natural rubber, so that it does not slip on water or oily floors.

Specialized shoes such as safety shoes manufactured in various ways as described above, or the general shoe has a function to prevent slipping on the material or shape of the sole. However, the sole in contact with water or oil is hardened over time, the anti-slip function is deteriorated, there is a problem of sliding more and more due to wear. As such, when the anti-slip function is lowered, the replacement cost is excessively used by replacing the safety shoes, and the risk of a safety accident remains by igniting the safety shoes that have lost the anti-slip function in order to reduce such expenses.

Therefore, the present invention can continue to use the safety shoes with reduced anti-slip function, and further prevents the prevention of safety accidents by distinguishing between more effectively preventing slippage by water and more effectively preventing slipping by oil. The purpose is to make it possible.

In order to achieve the above object is to provide a pad having a structure that can be easily worn on the shoe of the non-slip function or any shoe sole. That is, the pad can be worn on the sole of the shoe and has a structure that is easy to remove, and is made of a material suitable for water and oil.

By providing a structure that can be worn over the sole as described above, and by providing a structure that can be easily applied to each material suitable for water and oil, it can effectively prevent slip as a general shoe, hardening the sole By continuing to use specializations such as safety shoes with reduced slip protection due to wear and tear, it is possible to prevent frequent accidents as well as to prevent safety accidents.

In addition, a string hole 7 is formed in the instep ring 3, the rear axle 6, and the connecting portion 4, and a structure that can be fixed to a shoe using the string 8 is also possible.

In addition, the front body (1) and the rear body (5) is a material that does not slip in water, the front body (1) and the rear body (5) a plurality of oil-resistant adhesive pads (9) made of a material that does not slip in oil. It may be implemented in a structure to be attached. Of course, in this case, the front body 1 and the rear body 5 may be formed with an attachment groove 10 to which the oil-resistant pad 9 can be attached.

As described above, the present invention may simultaneously form a material that does not slip into water and oil on one pad, and may use only pads that do not slip into water. This is because the oil tight pad 9 can be attached to the front body 1 and the rear body 5 according to a selection.

The front body (1) and the rear body (5), which are non-slip in water, have 25 to 35% by weight of natural rubber (NR), 15 to 25% by weight of carbon M / B, and butadiene rubber (BR, Polybutadiene Rubber). ) 5-15 wt%, zincization 10-20 wt%, ST / acid 0.2-0.3 wt%, iron oxide 10-20 wt%, titanium oxide 10-20 wt%, tackifier 0.5-1.0 wt%, CZ 0.5- It consists of 1.0 weight%, D 0.2-0.3 weight%, TS 0.05-0.15 weight%, and sulfur 0.5-1.5 weight%.

In addition, the oil-resistant pad (9), which is non-slip to oil, has a nitrile butadiene rubber (NBR) of 25 to 35% by weight, carbon M / B 15 to 25% by weight, butadiene rubber (BR, Polybutadiene Rubber) 5 ~ 15% by weight, galvanized 10-20% by weight, ST / acid 0.2-0.3% by weight, iron oxide 10-20% by weight, titanium oxide 10-20% by weight, tackifier 0.5-1.0% by weight, CZ 0.5-1.0% by weight %, D 0.2-0.3 weight%, TS 0.05-0.15 weight%, and sulfur 0.5-1.5 weight%.

Properties of the material used in the above is as follows. First of all, natural rubber, which has a property of not slipping in water, has good feel and excellent mechanical properties among all rubbers, and is used in automobile tires, industrial truck tires, shoes, hoses, belts, air springs, general and industrial products, and the like.

Nitrile butadiene rubber, which is non-slip, has excellent oil resistance, abrasion resistance, and aging resistance, and is used in oil resistance products such as oil seals, gaskets, oil hoses, conveyor belts, printing rolls, and textile top rolls.

The following components are components included in both the characteristics which do not slip into water and those which do not slip in oil.

Carbon M / B contains carbon and improves strength. Butadiene rubber (BR) has better elasticity and better wear resistance than NR, and is used in industrial products such as tires for automobiles and airplanes, shoes, dustproof rubber, rubber rolls, belts, and hoses.

Zincation and ST / acid are used as vulcanizing agents, and zincation also acts as a vulcanization accelerator, making rubber products more useful.

Iron oxide and titanium oxide are used to improve friction, and a tackifier is used to impart adhesion to slip. A tackifier does not become a sticky adhesive just by melting a lump of rubber. It adds a special substance to show stickiness, which is a tackifier. Rubber is usually a polymer with a molecular weight ranging from hundreds of thousands to millions, but most of the tackifiers are from several hundred to three thousand. Many are synthesized, but pine pine rosin may be used.
