Description

Tread rubber composition for tires {TIRE TREAD RUBBER COMPOSITION}

The present invention relates to a tread rubber composition for a tire having excellent tensile properties and wear resistance by adding a natural mineral containing silica-carbon black to improve filler dispersibility.

In the configuration of the tire, the tread portion is one of the important components that express the required characteristics of the tire, the tire tread rubber is in direct contact with the ground during the movement of the vehicle to support the load of the vehicle, wear resistance is important, Carbon black is applied to improve this.

However, in consideration of future environmental problems, the use of carbon black, which is a petroleum-based material, should be restrained. Therefore, the use of silica is being considered to replace carbon black, which is an unfriendly environment. It has a disadvantage in that wear resistance and adhesive performance decrease.

The present invention is to provide a tread rubber composition for a tire excellent in tensile properties, adhesiveness and wear resistance by improving the dispersibility of the filler by adding a natural mineral containing silica-carbon black to solve the above problems. The purpose.

The tread rubber composition for tires according to the present invention is characterized in that it comprises 2 to 50 parts by weight of natural minerals containing silica-carbon black with respect to 100 parts by weight of the raw material rubber.

The raw rubber may be used natural rubber or synthetic rubber or mixed rubber of natural rubber and synthetic rubber, there is no particular limitation on the type and mixing ratio of the natural rubber and synthetic rubber.

The natural mineral containing silica-carbon black used in the present invention has an effect of lowering the viscosity, and is used to improve tensile properties and abrasion resistance. It comprises a weight percent, magnesium 1-2 wt%, aluminum 3-5 wt% and iron 4-7 wt%, the DBP adsorption amount is 15-50m 3 / g.

The content of the natural mineral containing silica-carbon black is preferably 2 to 50 parts by weight based on 100 parts by weight of the raw material rubber. If the content is less than 2 parts by weight, the physical properties are maintained, but the viscosity and wear resistance cannot be improved due to the trace amount. Therefore, it is not preferable, and when it exceeds 50 parts by weight, dispersibility is poor at the time of blending, and thus physical properties may decrease, which is not preferable.

In the rubber composition of the present invention, in addition to the above-mentioned components, additives commonly used in tread rubber compositions for tires, for example, process oils, stearic acid, anti-aging agents, zinc oxide, vulcanizing agents and vulcanization accelerators, etc. It can mix | blend in the range.

The tire tread rubber composition of the present invention improves the dispersibility of the filler by applying a natural mineral containing silica-carbon black, which is an environmentally friendly material, and improves various properties such as tensile properties, viscosity, wear resistance and adhesion.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, these examples do not limit the scope of the present invention.

Comparative example  And Example  1 ~ 4

After preparing the tread rubber composition for tires according to the composition of Table 1, each rubber composition was vulcanized at 160 ℃ to prepare rubber specimens, the physical properties according to ASTM standards, hardness, 300% modulus, tensile strength, elongation, rebound Exothermic, dynamic viscoelasticity, viscosity and wear resistance were measured, and the results are shown in Table 2 below.
