Description

트럭 및 버스용 트레드 고무조성물{Tread rubber composition for truck and bus}Tread rubber composition for truck and bus}

본 발명은 트럭 및 버스용 트레드 고무조성물에 관한 것으로서 보다 상세하게는 내마모성능을 향상시키면서 내커팅 칩핑(anti-cutting chipping) 성능이 유지되는 트럭 및 버스용 트레드 고무조성물에 관한 것이다.The present invention relates to a tread rubber composition for trucks and buses, and more particularly, to a tread rubber composition for trucks and buses in which anti-cutting chipping performance is maintained while improving wear resistance.

산업활동이 다양해지면서 물동량이 폭발적으로 증가하고 있고 이에 따라 운송수단으로서 트럭 및 버스의 수요 또한 증가하고 있다. 트럭 및 버스는 단거리 및 장거리를 운행하면서 일시에 대량의 화물 또는 사람을 운송할 수 있어서 날로 그 수요가 계속적으로 증가하고 있다. 그러나 트럭 및 버스의 넓은 활동영역, 다양한 주행도로 여건에 비추어 볼 때 트럭 및 버스 타이어의 트레드 고무의 내마모성이 소비자의 요구수준에 미치지 못하고 있다.The diversification of industrial activities has led to an explosive increase in the volume of cargo, which also increases the demand for trucks and buses as a means of transportation. Trucks and buses are capable of transporting large quantities of cargo or people at one time on short and long distances, and the demand is increasing day by day. However, the abrasion resistance of the tread rubber of truck and bus tires does not meet the demands of consumers in view of the wide range of activities of trucks and buses and various road conditions.

종래 트럭 및 버스용 트레드 고무는 다양한 도로여건을 고려하여 서로 상반되는 성능인 내마모성능과 내커팅 칩핑 성능을 동시에 충족시키려는 목적으로 설계하여 상기 두 가지 성능의 중간정도 성능을 발휘하는 수준이었다. 그러나 도로여건이 개선되면서 내커팅 칩핑 성능보다는 내마모성능이 중요시되기 시작하여 우수한 내마모성능을 지닌 트럭 및 버스용 트레드 고무의 개발이 필요하게 되었다.Conventional truck and bus tread rubbers were designed to satisfy both abrasion resistance and cutting chipping performance, which are opposite to each other, in consideration of various road conditions, and exhibited intermediate performances of the two performances. However, as road conditions improved, wear resistance rather than cutting chipping performance began to be important, and development of tread rubber for trucks and buses with excellent wear resistance was required.

본 발명은 착해제를 첨가하여 소련작업을 거친 후 점도를 조절한 천연고무를 원료고무로 사용하고 그 외 공정조제로 이루어진 트레드 고무조성물을 이용하여 트레드 고무를 제조함으로써 종래의 내커팅 칩핑성능을 유지하면서 내마모성을 향상시킨 트레드 고무조성물을 제공하는 것을 목적으로 한다.The present invention maintains the conventional cutting chipping performance by using a natural rubber adjusted by the viscosity after the Soviet work by adding a complexing agent as a raw material rubber and by using a tread rubber composition consisting of other processing aids An object of the present invention is to provide a tread rubber composition with improved wear resistance.

본 발명의 트레드 고무조성물은 착해제를 첨가하여 소련작업을 거친 후 점도를 조절한 천연고무를 원료고무로 사용하고 그 외 공정조제로 구성된다.The tread rubber composition of the present invention uses a natural rubber whose viscosity is adjusted after the Soviet work by adding a complexing agent as a raw material rubber, and is composed of other process aids.

상기에서 원료고무로 사용하는 천연고무는 착해제로 2,2-디벤즈아미노디페닐디설파이드(2,2-Dibenzaminodiphenyldisulfide)를 천연고무 100 중량부에 대하여 0.8 ∼ 1.5 중량부를 사용하여 천연고무와 2∼5분간 배합한 후 140∼150℃에서 덤프하는 소련공정을 거쳐 천연고무의 점도를 60 ∼ 80으로 조절한 것을 사용한다.The natural rubber used as the raw material rubber is a natural rubber and 2 to 5 by using 2,2-dibenzaminodiphenyldisulfide (0.8-1.5 parts by weight) based on 100 parts by weight of 2,2-dibenzaminodiphenyldisulfide as a complexing agent. After mixing for a minute, using a Soviet process to dump at 140 ~ 150 ℃ to adjust the viscosity of natural rubber to 60 to 80 is used.

그 외 공정조제는 상기 원료고무 100 중량부에 대해 카본블랙 44∼54 중량부, 프로세스 오일 2.5∼5.5 중량부, 스테아린산 1.7∼2.4 중량부, 아연화 3.5∼4.3 중량부, 노화방지제 3.2∼3.9 중량부, 왁스0.8∼1.6 중량부, 유황 1.3∼1.8 중량부, 가황촉진제 0.63∼1.4 중량부이다.Other process aids are 44 to 54 parts by weight of carbon black, 2.5 to 5.5 parts by weight of process oil, 1.7 to 2.4 parts by weight of stearic acid, 3.5 to 4.3 parts by weight of zinc, 3.5 to 4.3 parts by weight of antioxidant, and 3.2 to 3.9 parts by weight of antioxidant. 0.8 to 1.6 parts by weight of wax, 1.3 to 1.8 parts by weight of sulfur, and 0.63 to 1.4 parts by weight of vulcanization accelerator.

상기 공정조제중 카본블랙은 요오드값이 118∼126mg/cc, DBP 흡유량은 112∼120 cm3/100g 이다.Carbon black in the preparation process is the iodine value of 118~126mg / cc, DBP oil absorption 112~120 cm 3 / 100g.
