Abstract
Disclosed herein are a tire composition for preventing sliding and a tire using the same. The tire composition contains 5 to 90 parts by weight of anti-slip particles having a particle size of 0.01 to 5 mm with 100 parts by weight of a rubber matrix, thus efficiently preventing sliding. In one embodiment, when the tire composition is used for a tire tread, the tread rubber contacting the road surface is primarily worn out and tungsten, hard metals, artificial diamond, cbn, corundum, ceramics or emery as anti-slip particles with superior anti-abrasion and hardness are exposed, thus efficiently preventing sliding on general roads, rainy roads, icy roads or snow-covered roads. Furthermore, anti-abrasion of tungsten, hard metals, artificial diamond, cbn, corundum, ceramics or emery used as the anti-slip particles with superior hardness and anti-deformation may impart long lifespan to tires. In addition, the anti-slip particles are homogeneously dispersed in the tread and are continuously exposed as the tread is worn out, thus maintaining sliding effects until the lifespan of the tread is finished.
Description
Embodiments of the present invention relate to a tire composition for preventing sliding. More specifically, embodiments of the present invention relate to a tire composition for preventing sliding on a road surface.
A car tire utilizes a variety of means for preventing sliding on a road surface. For example, there may be mentioned tires provided with tread grooves having various shapes or tires having surfaces provided with protrusions such as snow tires.
However, tires provided with tread grooves exhibit performance deterioration as they are worn out, and tires provided with protrusions disadvantageously cause excessive noise and damage to the road surface.
Therefore, it is one aspect of the present invention to provide a tire composition with superior slide prevention effects and a tire using the same.
Additional aspects of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
In accordance with one aspect of the present invention, provided is a tire composition for preventing sliding, prepared by mixing 5 to 90 parts by weight of anti-slip particles having a particle size of 0.01 to 5 mm with 100 parts by weight of a rubber matrix, wherein the anti-slip particles are selected from tungsten, hard metals, artificial diamond, cubic boronitride (cbn), corundum, ceramic and emery.
In accordance with another aspect of the present invention, provided is a tire for preventing sliding using the tire composition for a tire tread.
As apparent from the afore-going, a tire composition for preventing sliding and a tire using the same can efficiently prevent sliding by mixing anti-slip particles such as tungsten, a hard metal, artificial diamond, cbn, corundum, ceramics or emery with a rubber matrix. For example, when the tire composition is used for a tire tread, the tread rubber contacting the road surface is primarily worn out and anti-slip particles with superior anti-abrasion and hardness, composed of a material such as hard metals, artificial diamond, cbn, corundum, ceramics or emery are then gradually exposed, thus efficiently preventing sliding on general roads, rainy roads, icy roads or snow-covered roads. Furthermore, anti-abrasion of tungsten, hard metals, artificial diamond, cbn, corundum, ceramics or emery used as the anti-slip particles with superior hardness and anti-deformation may impart long lifespan to tires. In addition, the anti-slip particles are homogeneously dispersed in the tread and are continuously exposed as the tread is worn out, thus maintaining sliding effects until the lifespan of the tread is finished.
These and/or other aspects of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
FIG. 1 is a perspective view illustrating a tire used for the tire composition for preventing sliding according to one embodiment of the present invention.
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
The tire composition for preventing sliding according to the present invention is prepared by mixing 5 to 90 parts by weight of anti-slip particles having a particle size of 0.01 to 5 mm with 100 parts by weight of a rubber matrix, wherein the anti-slip particles are selected from tungsten, hard metals, artificial diamond, cubic boronitride (cbn), corundum, ceramic and emery.
The rubber matrix may be selected from generally-used rubbers including natural rubbers (MR), butadiene rubbers (BR), styrene butadiene rubbers (SBR), isoprene rubber (IR), nitrile rubber (NBR), chloroprene rubber (CR), butyl rubber (IIR), ethylene-propylene rubber (EPM or EPDM), chlorosulfonated polyethylene (CSM), acryl rubber, urethane rubber and combinations thereof.
Tungsten used as anti-slip particles is a material melted at a high temperature of 3,480˚C. Sintering is required to mold such a high-temperature material into the desired particles. The term “sintering” refers to a phenomenon wherein a solid powder is injected into a mold, pressured using a press and thus solidified, and aggregated or deposited and thus clustered on the surface wherein powders contact one another, when heated to about a melting point of the solid. Tungsten is processed into particles with a size of 0.01 to 5 mm through such a process. When tungsten particles have a size less than 0.01 mm, they can exhibit superior anti-wearing effect, whereas tungsten particles having a size exceeding 5 mm generate considerable noise and cause damage to the road surface, when contacting the road surface. Accordingly, the shape of tungsten particles may be irregular or angulated, rather than round.
Artificial diamond, which has a predetermined crystal shape, is a material for high-temperature processing and melts at 3,500˚C or higher. Accordingly, the artificial diamond may have a size of 0.01 to 5 mm. When an artificial diamond has a size less than 0.01mm, anti-abrasion effects can be obtained, but anti-sliding effects are almost completely eliminated, whereas the artificial diamond having a size exceeding 5 mm generates considerable noise and causes damage to the road surface, when contacting the road surface. The shape of tungsten particles may be irregular or angulated, rather than round.
Ceramic may be selected from silicon nitride ceramic, silicon carbide ceramic, sialon ceramic, alumina ceramic, zirconia ceramic, china, glass, reinforced glass and combinations thereof.
The tire composition may further comprise, in addition to the afore-mentioned rubber matrix and anti-slip particles, a common additive and cross-linking agent for rubbers.
Meanwhile, the anti-slip particles may be mixed in an amount of 5 to 90 parts by weight with respect to 100 parts by weight of the rubber matrix. When the anti-slip particles are present in an amount less than 5 parts by weight, attaining the desired level of sliding prevention effects is difficult, and when the anti-slip particles are present in an amount exceeding 90 parts by weight, hardness rapidly increases and a molded material becomes brittle.
As shown in FIG. 1, a conventional tire comprises a tread 1 contacting a road surface, a side well 2, a shoulder 3 interposed between the tread 1 and the side well 2, to emit heat generated during driving, and a bead 5 to mount the tire on a rim 4.
The afore-mentioned tire composition is used for the tread 1 contacting the road surface, which improves a frictional force with the ground surface and stably maintains anti-sliding effects. The tread 1 may be applied to car tire treads, airplane tire treads, motorcycle tire treads, bicycle tire treads, heavy machinery treads and the like.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
