[발명의 명칭][Name of invention]
특수 카플링제를 사용한 타이어 트레드의 고무 조성물Rubber composition of tire tread with special coupling agent
[발명의 상세한 설명]Detailed description of the invention
본 발명은 타이어 트레드 고무에 카본블랙-고무 카플링제로서 N,N'-비스(2-메틸-2-니트로프로필)-1.6 디아미노헥산 (N,N'- bis(2-methyl -2nitropropyl)-1, 6-diaminohexane)(이하 슈미파인(Sumifine) 1162이라 함)을 사용하여 트레드의 내마모성, 내 발열성, 조종안정성향상 및 저연비 특성을 갖게함을 특징으로 하는 트레드 고무 조성물에 관한 것이다.The present invention relates to tire tread rubber as N, N'-bis (2-methyl-2-nitropropyl) -1.6 diaminohexane (N, N'-bis (2-methyl-2nitropropyl)-as a carbon black-rubber coupling agent. 1, 6-diaminohexane (hereinafter referred to as Sumifine 1162) relates to a tread rubber composition characterized by having a tread wear resistance, exothermic resistance, improved steering stability and low fuel consumption.
일반적으로 트레드 고무의 마모성능을 향상시키려면 카본블랙을 다량 사용해야 하나 다량사용의 경우 자동차 주행중 타이어 내부의 온도가 상승하여 분리현상(Separation)을 유발시켜 사고 발생의 위험 및 재생(Recap)을 할 수 없어 실질적인 원가 상승의 원인이 되고, 연료절약형 트레드 고무로하기 위하여 구조가 큰 특수 카본블랙을 사용시 계수(Modulus)가 증가하여 주행중 트레드 고무 표면에 균열(Crack) 발생의 요인이 될 수 있으며, 또한 타이어의 조정안정성의 주요 인자인 견인력(Traction)을 향상시키기 위하여 스타이렌 부타디엔 코플리머 고무(SBR)을 사용해야 하나 이경우 주행중 타이어의 온도가 상승하여 타이어의 내구성을 저하시키며, 이러한 온도상승을 감소시키기 위하여는 특수 중합체인, 용액 중합시킨 S-SBR을 사용시 타이어의 제조원가가 증가하여 가격 상승의 원인이 될 수 있다.In general, a large amount of carbon black should be used to improve the wear performance of the tread rubber.However, in the case of heavy use, the temperature inside the tire rises during driving, causing separation, which may cause the risk of accidents and recap. As it is a fuel-saving tread rubber, the modulus increases when using a special carbon black with large structure, which can cause cracks on the surface of the tread rubber while driving. In order to improve the traction (Traction), which is the main factor of the stability of adjustment, styrene butadiene copolymer rubber (SBR) should be used.In this case, the tire temperature rises while driving to reduce the durability of the tire. Increasing tire manufacturing costs when using solution polymerized S-SBR, a special polymer W may be the cause of rising prices.
본 발명은 상기한 문제점들을 해소시켜 내마모성, 내 발열성, 조정안정성등을 향상시키면서도 연료가 절감되는 타이어의 트레드 고무 조성물을 제공하는데 목적이 있다.The present invention aims to provide a tread rubber composition of a tire in which fuel is saved while improving the wear resistance, heat resistance, adjustment stability, and the like by solving the above problems.
본 발명은 원료 고무로서 천연고무(Natural Rubber) 100phr (parts per hundred rubber)만을 사용하거나 천연고무 40phr 이상과 SBR, 폴리부타디엔 고무 60phr 미만을 사용하고 고무보강제로 사용한 카본블랙(C/B)은 N SA(질소 흡착법에 의해 측정한 비표면적)가 60-150㎎/g이고 DBPA(Dibutyl Phthalate Absorption)가 100-140㎖/100g인 것 30-70phr을 사용하고 여기에 C/B-고무의 카플링제로서 슈미핀(Sumifine) 1162를 최고 3phr까지 첨가함을 특징으로 하는 타이어 트레드 고무의 조성물에 관한 것이다.The present invention uses only 100 phr of natural rubber (parts per hundred rubber) as the raw material rubber, or more than 40 phr of natural rubber and less than 60 phr of SBR, polybutadiene rubber, and carbon black (C / B) used as a rubber reinforcement is N 60-150 mg / g SA (specific surface area measured by nitrogen adsorption) and 100-140 ml / 100 g of DBPA (Dibutyl Phthalate Absorption) using 30-70 phr, and the C / B-rubber coupling agent As a composition of a tire tread rubber characterized by adding up to 3 phr of Sumifine 1162.
특히 본원에서는 카플링제를 첨가함으로 C/B의 고무 매트릭스에 대한 분산성이 향상되고, C/B-고무간의 계면에서 타이어 주행시 에너지 손실을 최소화 함으로써 트레드 고무의 발열을 감소시킥 되어 이로 인해 내구성을 증대시키면서 차량의 C/B을 트레드 고무에 사용할 수 있어 내마모 저항성을 현저하게 향상시키게 된다. 또한 습기중 견인력(wet Traction)이 증가되어 차량의 조정안정성을 향상시키면서 타이어 주행시 에너지 손실을 최소화시킴으로서 주행중 연료 절감의 효과를 나타내는 특징이 있다.In particular, the addition of the coupling agent improves the dispersibility of the rubber matrix of C / B, and reduces the heat generation of the tread rubber by minimizing energy loss when running tires at the interface between C / B-rubber, thereby improving durability. Increasingly, the C / B of the vehicle can be used for the tread rubber, which significantly improves the wear resistance. In addition, the wet traction is increased to improve the steering stability of the vehicle while minimizing the energy loss while driving the tire, it is characterized by the effect of saving fuel while driving.
본 발명에서 사용되는 고무-C/B 카플링제는 천연고무에 사용시 가장 효과적이며, 천연고무와 SBR 혼합 및 천연고무와 폴리부타디엔(BR) 혼합의 경우에도 효과적이었으나 SBR 및 폴리부타디엔 단독사용(100phr) 또는 SBR, BR의 사용정도가 60phr 이상인 경우에는 그 효과가 경미하였다. 또한 C/B-고무간 카플링제를 4phr 이상 사용시에도 효과가 경미하였다.The rubber-C / B coupling agent used in the present invention is most effective when used in natural rubber, but also effective in mixing natural rubber and SBR and mixing natural rubber and polybutadiene (BR), but using SBR and polybutadiene alone (100 phr). Or, when the use degree of SBR, BR is more than 60phr, the effect was slight. In addition, even when the C / B-rubber coupling agent is used more than 4phr, the effect was slight.
