8 shows a photograph of a curved surface and a flat surface of a non-slip rubber surface structure using an electron microscope and a photograph of a conventional product.

The reason why the rubber composition of the shoe sole is prevented from slipping when the shoe sole touches the ground and becomes worn is as follows.

Component: Silicon carbide with high density between GRITs, Sharp Shape and high strength, high wear and high tensile strength of MOHS hardness 9, so that when the rubber of the shoe outsole touches the ground and wears Particles of silicon carbide (SiC) in the rubber composition act as an eisen to protrude from the sharp geometry to prevent ice and slip on the ground.

A shoe sole with a rubber composition for preventing slippage of the present invention

shoes; And a shoe sole attached through the shoe and the adhesive member and made of a rubber composition having a slip prevention function and formed with a slit at regular intervals,

The rubber composition of the shoe sole is made of nitrile rubber (NBR) and natural rubber (SMR) as the main raw material, and the phenylalkylade resin and the high-strength silica are mixed with the new material to make a vulcanized rubber, Silicone rubber (SiC) particles of the shoe sole are protruded even when the shoe sole is worn out, and the silicon carbide particles protruded by the protruded silicon carbide particles It features features such as an eisen effect to prevent slippage of the shoe soles.

For example, the unit block structure of the rubber composition for preventing slippage of the shoe sole may include protrusions opposed to each other in a 'Z' shape, or in other embodiments, first protrusions 101-1 and 101- 2 and the second protrusions 102-1 and 102-2 having a shape of '=' or a unit block structure of mutually opposing shapes such as a '' shape and a 'shape' .

In one embodiment, the shoe sole 100 includes a Z-shaped protrusion 101 and a protruding portion (not shown) formed in a unitary structure in which the body of the rubber composition for preventing slippage is attached, And concave suction portions 104-1 and 104-2 formed concavely in the inside of the shoe sole 101 and drain holes 103-1 and 103-2 for absorbing the moisture adhering to the sole of the shoe when rain or snow comes in, do.

In another embodiment, the shape of the first and second projections may be the same as that of the unit block structure. The first projections 101-1 and 101-2 having '11' shape and the second projections 102-1 ' , 102-2), a concave suction portion 104 formed concavely in the protruding portion 101, and a drain port 103 through which moisture adhering to the sole of the shoe is absorbed when rain or snow comes in, The structure of the unit block and its shape can be variously applied.

In another embodiment, the unit blocks formed in a matrix structure spaced apart from each other by a predetermined distance include a first protrusion 101 having a 'U' shape and a first protrusion 101 having a ' A concave adsorption part 104 formed concavely in the first projection part 101 and the second projection part 102 and a concave adsorption part 104 formed in the first projection part 101 and the second projection part 102, 1 and second drain ports 103-1 and 103-2.

The space inside the first and second protrusions 101 and 102 serves as a rubber sucker to prevent slippage due to the adhesive force between the ground and the shoe sole when the shoe sole comes into contact with the ground surface of the rubber composition.

In the shoe sole 100, a plurality of scales are formed at the previous intervals along the transverse direction or the longitudinal direction of the shoe sole 100, or along the diagonal direction.

A depth of a slit of 1/4 depth is 1 m / m when the total thickness of the first and second projections of the shoe sole is 4 m / m, A plurality of cutting lines are formed in the lateral direction, the longitudinal direction, or the diagonal direction.

The depth of the slits of the total thickness of the first and second projections 101 and 102 from the protruding surface of the shoe sole to the body is 23% to 64% of the total thickness of the first and second projections 101 and 102 .

For example, when the total thickness of the first and second protrusions 101 and 102 from the protruded surface of the shoe sole to the body is 4 mm, a slit can be formed at a constant interval of 1 mm to 2 mm .

In addition, the interval between adjacent slugs may be 3 to 7 mm.

When the shoe outsole 100 is mounted on the shoe by the cutting line L1, the part where the cutting line L1 is formed strengthens the adhesion force between the ground and the shoe sole.

When the depth of the cutting line L1 is 40% to 60% of the total thickness T1 of the shoe outsole 100, the shoe outsole 100 is torn or broken due to the cutting line L1 And an effect of improving the adhesive force by the cutting line L1 is obtained.

The shoe sole fabric 100 contains the same materials (nitrile rubber, natural rubber, reinforcing agent, pressure-sensitive adhesive, crosslinking agent, vulcanization accelerator, additives) in the same amount as the non-slip rubber composition, ) Are also included.

The strength of the silicon carbide (SiC) is so high as to have a room temperature bending strength of 70 to 90 kg / mm 2. Even if other materials of the shoe outsole are worn, silicon carbide (SiC) Respectively.

As shown in FIG. 3, when the shoe sole 100 is worn out, the silicon carbide particles are not worn out and the silicon carbide protrudes from the shoe sole. As the shoe sole wears more, the protruding length of silicon carbide So that it is prevented from slipping like an Eisen effect.

The surface of the silicon carbide (SiC) particles is rugged and sharply scratched even when the shoe sole is worn, and the shoe sole comes into contact with the ground of the shoe sole and the protruding silicon carbide (SiC) particles made of silicon carbide particles in the shoe sole To prevent slippage of the shoe sole as if it were an eisen effect. Unlike ordinary shoes that do not have a slip-resistant function, the shoe sole wears more and prevents the shoe from slipping.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken in conjunction with the present invention. The present invention can be variously modified or modified.
