트럭버스용 타이어의 트레드 고무조성물{Tread compound for truck and bus tire}Tread compound for truck and bus tire

본 발명은 트럭버스용 타이어의 트레드 고무조성물로서, 보다 상세하게는 내열 및 내마모 특성이 우수한 고속도로를 주행하는 트럭 및 버스용 타이어의 트레드 고무조성물에 관한 것이다.The present invention relates to a tread rubber composition of a tire for truck buses, and more particularly, to a tread rubber composition of truck and bus tires for driving on a highway having excellent heat and wear resistance.

산업화의 진행에 따른 포장도로의 증가에 의해 고속주행이 증가하고 있으나,트럭 및 버스용 트레드 고무로 가장 많이 사용하는 천연고무를 원료고무로 하는 고무조성물은 천연고무의 불포화결합(unsaturated bond)과 이중결합(double bond)때문에 고속주행시 발생하는 열에 의해 내마모 특성의 하락과 고무의 물성중 인열특성, 불균일한 마모 및 편마모 현상의 원인이 되고 있다.High speed driving is increasing due to the increase of pavement along with industrialization, but rubber composition which uses natural rubber, which is the most used as tread rubber for trucks and buses, is made of unsaturated bond and Due to the double bond, the heat generated during high-speed driving causes a decrease in the wear resistance, tearing properties of the rubber properties, uneven wear and uneven wear.

타이어용 트레드의 내열특성과 내마모 특성은 지면과 접하는 트레드 표면층의 성질에 의해 결정되는데, 고속주행시 필연적으로 따르는 열발생은 물성하락 및 내마모특성 저하의 원인이 되고 있다.The heat resistance and abrasion resistance of the tread for tires are determined by the properties of the tread surface layer in contact with the ground. The inevitable heat generation during high-speed driving causes the deterioration of physical properties and wear resistance.

종래에는 이러한 현상을 해결하기 위하여 고무에 내열특성이 양호한 노화방지제를 사용하거나, 고무의 혼용사용 즉 천연고무(NR)/스티렌-부타디엔고무(SBR), 천연고무/부타디엔 고무(BR) 또는 천연고무/스티렌-부타디엔고무/부타디엔 고무의 형태로 고무를 혼용하여 사용하는 방법, 또는 가교결합제를 다중 황결합(polysulfide bond) 보다는 단일 황결합(monosulfide bond)으로 변경시켜 열안정성을 개선시키는 방법이 시도되어 왔다.Conventionally, in order to solve such a phenomenon, an anti-aging agent having good heat resistance is used for rubber, or a mixed use of rubber, that is, natural rubber (NR) / styrene-butadiene rubber (SBR), natural rubber / butadiene rubber (BR) or natural rubber In the form of / styrene-butadiene rubber / butadiene rubber, a method of using a mixture of rubber or a method of improving the thermal stability by changing the crosslinking agent into a single sulfur bond (monosulfide bond) rather than a polysulfide bond has been tried. come.

그러나, 이러한 종래의 방법들은 고무의 물성중 특히 인장강도 특성과 타이어에서 요구되는 저연비 특성 및 제동력 특성을 동시에 만족시키기에는 한계를 지니는 문제점이 있다.However, these conventional methods have a problem in that rubber properties, in particular, have a limitation in satisfying tensile strength characteristics, low fuel consumption characteristics and braking force characteristics required in tires at the same time.

상기 실시예 및 비교예에서 제조한 고무조성물을 145℃에서 30분 동안 30톤의 하중을 가한 상태에서 가류시켜 인장시편을 제조한 다음 경도, 300% 모듈러스, 인장강도, 신장율(elongation break), 파괴율 (reversion ratio), 마모성능(PICO) 및 발열특성을 측정하였다.The rubber compositions prepared in Examples and Comparative Examples were vulcanized under a load of 30 tons at 145 ° C. for 30 minutes to prepare tensile specimens, followed by hardness, 300% modulus, tensile strength, elongation break, and fracture.

상기의 표 2에서 보는 바와 같이, DBTH와 6-QDI를 사용한 고무조성물은rdhsrkfb시 내열노화 특성이 현저히 개선되었음을 알 수 있다. 특히 발열특성은 DBTH와 6-QDI를 사용한 경우가 DBTH와 6-QDI를 사용하지 않은 경우 보다 저발열특성을 나타내었으며, 혼용 사용한 경우 저발열특성 및 내마모특성이 현저히 개선되었다.As shown in Table 2 above, it can be seen that the rubber composition using DBTH and 6-QDI has significantly improved heat aging characteristics during rdhskrkb. In particular, the exothermic properties of DBTH and 6-QDI were lower than those of DBTH and 6-QDI, and the low heat and wear resistance were significantly improved.

DBTH나 6-QDI를 단독으로 사용한 경우 DBTH와 6-QDI를 혼용 사용한 경우 보다 내열노화 특성 및 내마모특성의 개선이 상대적으로 미미함을 알 수있는데, 이는 DBTH와 6-QDI이 가류공정시 배가효과가 있음을 보여주고 있다.In case of using DBTH or 6-QDI alone, the improvement of heat aging characteristics and abrasion resistance is insignificant compared to the case of mixing DBTH and 6-QDI alone. This means that DBTH and 6-QDI doubled during the vulcanization process. It shows the effect.

또한, 고온가류시 가교결합율의 파괴율(reversion ratio) 면에서도 DBTH와 6-QDI를 혼용하여 사용한 경우가 DBTH와 6-QDI를 전혀 사용하지 않은 경우 보다 현저하게 우수한 효과를 나타내었다.In addition, the use of DBTH and 6-QDI in combination with the breakdown ratio of crosslinking rate during high temperature curing showed a remarkably superior effect than when DBTH and 6-QDI were not used at all.

<시험예 2><Test Example 2>

본 발명에 의한 트레드 고무조성물을 이용하여 제조한 11R22.5 956 규격 타이어의 내마모성능 및 편마모 발생율을 시험하였는데, 그 결과를 표 3에 나타내었다. 이때에 내마모성능의 지수는 DBTH와 6-QDI를 전혀 사용하지 않은 비교예 1을 100으로 한 값으로서, 내마모 지수가 높을수록, 편마모 발생율이 낮을수록 성능이 우수함을 의미한다.The abrasion resistance and wear resistance of the 11R22.5 956 standard tires manufactured using the tread rubber composition according to the present invention were tested. The results are shown in Table 3. In this case, the index of wear resistance is a value of 100 as Comparative Example 1, which does not use DBTH and 6-QDI at all, which means that the higher the wear index and the lower the occurrence of uneven wear, the better the performance.

상기 표 3에서 보는 바와 같이, DBTH와 6-QDI를 혼용하여 사용한 경우의 내마모 특성이 상대적으로 우수한데, 이는 DBTH와 6-QDI를 전혀 사용하지 않은 경우 보다 편마모 발생이 상대적으로 적게 발생하였고, 내열노화 특성의 차이에서 기인되고 있음을 알 수 있다.As shown in Table 3, the wear resistance when the mixed use of DBTH and 6-QDI is relatively excellent, which is relatively less abrasion occurrence than when the DBTH and 6-QDI is not used at all, It can be seen that it is due to the difference in heat aging characteristics.

본 발명에 의한 트럭버스용 타이어의 트레드 고무조성물은 내열 및 내마모 특성이 우수하여 고속주행시 필연적으로 따르는 열발생에 의한 내열 및 내마모특성 저하 등과 같은 물성변화를 방지할 수 있다.The tread rubber composition of the tire for truck buses according to the present invention is excellent in heat and abrasion resistance to prevent changes in physical properties such as deterioration of heat and abrasion resistance due to heat generation inevitably during high speed driving.
