Problems solved by technology

However, this technology has a disadvantage of lowering the braking performance on wet roads and adjusting the stability performance, which are the main characteristics of the tire tread, as the amount of reinforcing filler is reduced
[0005] As described above, in the current tire material development technology, generally, when the fuel consumption performance of the tire is improved, the braking performance on wet roads is lowered instead, and when the braking performance on wet roads is improved, the Situations where low fuel consumption performance is unfavorable

experiment example 2

[0131] [Experimental Example 2: Performance Experiment of Tire]

[0132] Treads were manufactured using the rubbers prepared in the above-mentioned Examples and Comparative Examples, and then 245 / 40ZR18-sized tires using the above-mentioned treads as semi-finished products were manufactured. The brake performance and rolling resistance on dry and wet roads of the above tires were tested, and then the relative ratios of Examples 1 to 6 and Comparative Example 2 with respect to the results of the tire of Comparative Example 1 are shown in Table 3 below.

[0133] table 3

[0134]

[0135] Referring to the above-mentioned Table 3, it can be confirmed that in the case of the tires of Examples 1 to 6, by maintaining the rolling resistance at the same level as before, it is possible to minimize the impairment of the low fuel consumption performance and realize extremely dry roads and wet roads Excellent braking performance and high handling performance.

Abstract

The present invention relates to a rubber composition used for tire treads and tires manufactured using the same. The rubber composition used for tire treads includes: 100 parts by weight of raw rubber; 100 to 150 parts by weight of silica; and 15 to 60 parts by weight of resin, the softening point of the above resin is 100 to 150 ° C, wherein the above-mentioned raw rubber includes solution-polymerized styrene-butadiene rubber, and in the above-mentioned solution-polymerized styrene-butadiene rubber, styrene The ethylene content is 8 to 30% by weight, and the vinyl content contained in butadiene is 20 to 35% by weight, and the molecular weight distribution of the above-mentioned solution-polymerized styrene-butadiene rubber is 2 to 5, so that the low fuel consumption performance can be maintained , and improves braking performance and handling performance on extremely dry and wet roads.

Description

technical field [0001] The present invention relates to a rubber composition for tire treads and a tire manufactured using the same, and to a rubber composition for tire treads which maintains low fuel consumption performance and improves braking performance and handling performance on extremely dry roads and wet roads Rubber compositions and tires made using them. Background technique [0002] Recently, due to the high performance of automobiles, consumers are also demanding high performance of tires. In particular, in the case of high-performance tuning cars and sports cars, the demand for low fuel consumption performance is very high due to the introduction of braking performance and handling performance on extremely dry and wet roads and the global labeling system. high. Therefore, as a demand for tires each having wear resistance, handling performance and ride performance, wet braking and low fuel consumption, application of new concept materials is being actively stu...
