Embodiment Construction

[0008] In order to achieve the above objects, the present invention is characterized in that, in a general rubber composition for tire treads for racing cars, 100 to 200 parts by weight of total carbon black is used with respect to 100 parts by weight of the raw material rubber. Weight%~90% by weight, iodine (I 2 ) adsorption amount is 130~250mg / g and DBP oil absorption is 120~140ml / 100g carbon black and 10% by weight~95% by weight, iodine (I 2 ) carbon black with an adsorption capacity of 250 to 400 mg / g and a DBP oil absorption capacity of 100 to 140 ml / 100 g.

[0009] Hereinafter, the present invention will be described in more detail as follows.

[0010] The filler of the present invention mixes two kinds of carbon blacks with different particle diameters. Specifically, 100 to 200 parts by weight of total carbon black is used with respect to 100 parts by weight of raw rubber, and the total carbon black is 5 to 90 parts by weight. % iodine (I 2 ) adsorption amount is 130...

Abstract

The invention provides a rubber composition for the tire surface of a tire for racing. The composition is provided with 100 to 200 weight portions of carbon blacks relative to 100 weight portions of raw rubber. The carbon black consists of 5 to 90 weight portions of carbon black whose iodine (I<2>) absorption quantity is 130 to 250mg / g and DBP oil absorption quantity is 120 to 140ml / g, and 10 to 95 weight portions of carbon black whose iodine (I<2>) absorption quantity is 250 to 400mg / g and DBP oil absorption quantity is 100 to 140ml / g. the invention can increase the traction performance and even increase the durability by combining two carbon blacks whose particle sizes are different with each other.

Description

technical field [0001] The present invention relates to a rubber composition for tire treads of drag racing cars, and provides a rubber composition capable of improving grip performance especially on dry road surfaces. Background technique [0002] In rubber compositions for tire treads of drag racing cars, carbon black with a small particle size is usually used to increase the rate of heat generation and improve the grip performance on dry road surfaces. [0003] And based on such a concept, attempts have been made to add carbon black with a small particle size in an amount greater than that in general rubber compositions for tire treads in order to maximize performance improvement. [0004] However, when the amount of carbon black with a small particle size is increased in this way, the grip performance at the time of braking and handling (Handling) is improved, but on the other hand, there is a problem that the durability of the tire during running and the tire durability...
