Description
본 발명은 타이어 트레드용 고무 조성물 및 이를 이용하여 제조한 타이어에 관한 것으로, 미가류 상태에서 가공성이 우수하며, 제동 성능과 마모 성능 및 저연비 성능을 모두 향상시킬 수 있는 타이어 트레드용 고무 조성물 및 이를 이용하여 제조한 타이어에 관한 것이다.The present invention relates to a rubber composition for a tire tread and a tire produced therefrom, which is excellent in workability in an uncrosslinked state and can improve both braking performance, wear performance and fuel consumption performance, and a rubber composition for tire tread The present invention relates to a tire manufactured by the method.
최근 승용차의 고성능화로 인해 소비자들은 타이어의 고성능화를 동시에 요구하고 있으며, 특히 내마모성, 핸들링(Handling)과 라이드(Ride) 성능, 웨트 제동성 및 저연비성을 모두 겸비하고 있는 타이어에 대한 요구로 새로운 소재의 응용이 적극적으로 검토되고 있다. Recently, due to the high performance of passenger cars, consumers are demanding high performance of tires. In particular, there is a demand for tires that have abrasion resistance, handling and riding performance, wet braking performance and low fuel consumption. Applications are actively being reviewed.
또한, 이러한 타이어의 내마모성, 제동성, 핸들링 및 라이드 성능 그리고 저연비성을 동시에 겸비한 타이어에 대한 기술 개발은 특히 재료분야에서 많이 이루어 지고 있다. 그러나 성능을 향상시키는 과정에서 컴파운드의 가공성이 악화되는 문제가 발생하므로 컴파운드의 양산을 위해서 컴파운드의 가공성을 향상시킬 필요가 있다.In addition, the development of technology for tires having both abrasion resistance, braking performance, handling and riding performance and low fuel consumption of such tires has been made particularly in the field of materials. However, since the processability of the compound deteriorates in the process of improving the performance, it is necessary to improve the processability of the compound in order to mass-produce the compound.
일반적으로 타이어의 연비 성능과 관련이 있는 회전저항을 감소시키는 기술로 보강성 충진제의 양을 줄이는 방법이 있다. 충진제의 양이 줄어들면 보강제와 보강제간의 상호 작용이 감소하여 히스테리시스 로스가 줄어듦으로 회전저항을 낮출 수 있지만, 타이어 트레드의 중요한 특성인 제동성능 및 조정 안정성능도 함께 저하되는 문제가 있다.In general, there is a method of reducing the amount of reinforcing filler by a technique of reducing the rolling resistance which is related to the fuel efficiency of a tire. If the amount of the filler is decreased, the interaction between the reinforcing agent and the reinforcing agent is reduced to reduce the hysteresis loss, thereby lowering the rolling resistance. However, the braking performance and the adjustment stability performance, which are important characteristics of the tire tread, also deteriorate.
이처럼 현재 타이어 재료 개발 기술에서 일반적으로 타이어의 마모 성능 및 연비 성능을 향상시키면, 제동 성능은 오히려 저하되는 경우가 발생하고, 타이어의 제동 성능을 향상시킬 경우 저연비 성능이 불리하게 되거나 마모 성능이 저하되는 현상을 보이기 때문에 한 가지 성능을 향상시키면서 다른 한 가지 성능의 저하를 최소화 하거나, 동시에 두 가지 성능을 향상시킬 수 있는 기술의 개발이 요구되고 있으며, 이와 더불어 양산을 위한 컴파운드 가공 기술 및 컴파운드 자체의 가공성을 향상시키는 기술 개발이 요구되고 있다.In general, in the present tire material development technology, when the abrasion performance and the fuel consumption performance of the tire are improved, the braking performance is rather lowered. When the braking performance of the tire is improved, the fuel consumption performance is deteriorated or the abrasion performance is degraded It is required to develop a technology capable of improving one performance while minimizing deterioration of one performance or improving two performance at the same time. In addition to this, it is required to develop a compound processing technique for mass production and a processability And the like.
본 발명의 목적은 제동 성능과 마모 성능 및 저연비 성능이 우수하면서, 양산을 위한 컴파운드 가공 기술 및 컴파운드 자체의 가공성이 향상된 타이어 트레드용 고무 조성물을 제공하는 데 있다.An object of the present invention is to provide a rubber composition for a tire tread having excellent braking performance, abrasion performance and low fuel consumption performance, compound processing technology for mass production, and processability of the compound itself.

상기 BR은 타이어 고무 조성물에 사용되는 부타디엔 고무라면 어느 것이든 사용 할 수 있다. 상기 BR이 오일을 함유하지 않은 경우 저연비특성 및 가공성에서 유리한 효과가 있다. The BR may be any butadiene rubber used in the tire rubber composition. When the BR does not contain oil, it is advantageous in terms of low fuel consumption characteristics and processability.

If the amount is less than 10 parts by weight, the processability and wear resistance of the rubber composition may be impaired. If the amount is more than 40 parts by weight, the tire may have a low fuel consumption performance. If the BR is less than 10 parts by weight, the abrasion performance may be deteriorated. If the BR is more than 30 parts by weight, the proportion of the butadiene rubber having a relatively low rubber strength may be increased.

상기 실시예 및 비교예에서 제조한 고무 시편에 대하여 물성을 측정하였고, 그 결과를 하기 표 3에 나타내었다.The physical properties of the rubber specimens prepared in the above Examples and Comparative Examples were measured, and the results are shown in Table 3 below.
(1) 무니점도(ML1+4(125℃)(1) Mooney viscosity (ML1 + 4 (125 DEG C)
무니점도는 미가류 고무의 점도를 나타내는 값으로 수치가 낮을수록 미가류 고무의 가공성이 우수한 것을 나타내며, ASTM 규격 D1646에 의해 측정하였다.The Mooney viscosity is a value indicating the viscosity of the unvulcanized rubber. The lower the numerical value, the better the workability of the unvulcanized rubber and measured by ASTM standard D1646.
(2) 경도(2) Hardness
경도는 조정 안정성을 나타내는 것으로 수치가 높을수록 조정 안정성능이 우수한 것을 나타내며, DIN 53505에 의해 측정하였다The hardness indicates the adjustment stability, and the higher the value, the better the adjustment stability performance, which was measured according to DIN 53505
(3) 300% 모듈러스 및 신장율(3) 300% modulus and elongation
300% 모듈러스와 신장율은 수치가 높을수록 인장특성이 우수함을 나타내고, 내마모도는 값이 클수록 내마모 성능이 우수함을 나타내며,ISO 37 규격에 의해 측정하였다. 이때 신장률은 파단시 신장률을 의미하는 것으로 인장 시험기에서 시험편이 끊어질 때까지의 Strain 값을 %로 나타내는 방법으로 측정하였다.The 300% modulus and elongation percentage indicate higher tensile properties as the numerical value increases, and the higher the value of the wear resistance, the better the abrasion resistance performance, measured according to the ISO 37 standard. The elongation at this time means the elongation at break, which is measured by a method in which the strain value until the test piece is broken in a tensile tester expressed as a percentage.

상기 표3을 참조하면, 본 발명에 따라 회분식 방식으로 제조된 용액 중합 스티렌-부타디엔 고무와 연속식 방식으로 제조된 용액 중합 스티렌-부타디엔 고무를 사용한 실시예1 내지 5의 고무 조성물의 경우에는 회분식과 연속식 방식을 각각 단독으로 사용한 비교예1 및 2의 고무 조성물과 비교하여 회전 저항 성능과 제동성능이 향상되었다. 특히 실시예4,5의 경우 현저히 우수한 회전저항 성능과 높은 젖은 노면 제동 성능(Wet Grip)을 나타내는 것을 확인하였다.Referring to Table 3, in the case of the rubber compositions of Examples 1 to 5 using the solution-polymerized styrene-butadiene rubber produced in a batch manner and the solution-polymerized styrene-butadiene rubber produced in a continuous manner according to the present invention, The rotational resistance performance and the braking performance were improved as compared with the rubber compositions of Comparative Examples 1 and 2 which used the continuous type alone. In particular, it was confirmed that Examples 4 and 5 exhibit remarkably excellent rolling resistance performance and high wet road surface braking performance (wet grip).
비교예2 내지 5의 경우 비교예1 보다 마모도가 개선된 결과를 보였으나 이는 높은 부타디엔 고무의 함량 때문인 것으로 판단된다. 비교예1의 경우 회전저항 성능은 비교적 우수하나 제동 성능이 현저히 저하되는 것을 확인하였다. 비교예3 및 4의 고무조성물의 경우 연속식 방식으로 제조된 용액 중합 스티렌-부타디엔 고무를 사용하지 않거나 미달하게 사용한 경우, 고무조성물의 가공성이 저하되는 것을 확인하였다. 또한, 비교예5의 회분식 방식으로 제조된 용액 중합 스티렌-부타디엔 고무를 미달하여 사용한 경우 타이어의 저연비 성능이 저하되는 것을 확인하였고, 비교예6의 경우는 연속식 방식으로 제조된 용액 중합 스티렌-부타디엔 고무와 부타디엔 고무를 사용하였을 때는 젖은 노면 제동 성능이 낮아지는 결과를 보였다.
In Comparative Examples 2 to 5, the wear resistance was improved as compared with Comparative Example 1. However, it is considered that the content of butadiene rubber is high. In the case of Comparative Example 1, it was confirmed that the rotational resistance performance was comparatively excellent but the braking performance remarkably decreased. In the case of the rubber compositions of Comparative Examples 3 and 4, it was confirmed that the processability of the rubber composition was lowered when the solution-polymerized styrene-butadiene rubber prepared by the continuous method was not used or used in a lesser extent. In addition, it was confirmed that when the solution-polymerized styrene-butadiene rubber produced by the batch method of Comparative Example 5 was used in a short time, the fuel-efficiency of the tire was lowered. In Comparative Example 6, the solution polymerization styrene-butadiene When rubber and butadiene rubber were used, wet road surface braking performance was lowered.
