Description

검 체파용 고무조성물{Gum Chafer Compound for Tire}Gum Chafer Compound for Tire

본 발명은 검 체파(GUM Chafer)용 고무조성물로서 보다 상세하게는 마모 및 발열특성을 개선하기 위해 원료고무에 부타디엔 고무를 적량 혼입하고, 또한 공기 혼입에 따른 불량율을 감소하기 위해 적량의 TR을 첨가한 검 체파용 고무조성물에 관한 것이다.The present invention is a rubber composition for GUM Chafer, and more specifically, butadiene rubber is mixed in the raw material rubber in order to improve wear and heat generation characteristics, and an appropriate amount of TR is added to reduce the defect rate due to air mixing. The present invention relates to a rubber composition for somatic wave.

현재 타이어 제조공정에는 생산성을 제고하기 위해 종래 사용되어 오던 패브릭 체파에서 검 체파로의 전환이 시도되고 있다. 검 체파는 성형공정의 1 단계를 생략할 수 있어 생산성을 향상시키는데 적합하다. 하지만 현재까지는 고하중이 아닌 PCR 타이어에서 적용 중이며 LTR 이상의 규격에서는 아직까지도 패브릭 체파가 사용되고 있다.At present, in the tire manufacturing process, a change from fabric sieving to sample sieving, which has been conventionally used to improve productivity, is being attempted. The sample wave can be omitted in step 1 of the molding process, which is suitable for improving productivity. However, it is currently applied to PCR tires, not heavy loads, and fabric sowing is still used in LTR and above specifications.

체파는 비드부를 감싸주어 타이어의 코드를 보호해주는 컴포넌트로서 타이어 림과 마찰되는 부위로 림과 코드의 직접 접착을 방지하여 코드를 보호하며 우수한 마모저항 및 열저항 특성이 요구되는 부위이다.Cheongpa is a component that wraps the bead and protects the cord of the tire. It is a part that rubs against the tire rim to prevent the direct adhesion of the rim and the cord to protect the cord, and requires excellent wear resistance and heat resistance.

현재까지 공개된 체파 고무조성물에 의하면 마모저항 및 열저항에 있어 그열악함을 면치 못하고 있을 뿐만 아니라, 타이어의 성형공정에서 여러 반제품들이 성형되는 과정 중에 공기(Air)가 혼입되고 이들 공기가 가류 후 배출 또는 소멸되지 않고 타이어내에 그대로 존재하여 불량 타이어를 생산하는 결과가 야기되고 있다.According to the sovereign rubber composition disclosed to date, not only is it poor in abrasion resistance and heat resistance, but also air is mixed during the process of forming various semi-finished products in the tire forming process and these air is vulcanized after There is a result of producing a bad tire by remaining in the tire without being discharged or extinguished.

특히 검 체파를 사용하는 경우 패브릭 체파를 사용하는 경우보다 공기 배출능이 결여되어 비드부에서 공기입 발생에 의한 불량률이 2%에 달할 정도로 크게 나타나고 있다.In particular, when using a sample wave, air discharge capacity is less than that of using a fabric wave, resulting in a defect rate of 2%.

본 발명은 상기와 같이 종래의 검 체파가 지니는 문제점인 마모 및 열 저항특성이 향상된 고무조성물을 제공함에 목적이 있다.The present invention has an object to provide a rubber composition with improved wear and heat resistance characteristics which is a problem with the conventional sample wave as described above.

또한 본 발명의 또 다른 목적은 종래의 검 체파가 지니는 공기입에 따른 불량률을 감소시킨 고무조성물을 제공함에 있다.It is still another object of the present invention to provide a rubber composition which reduces the defect rate according to the air intake of the conventional sample wave.

본 발명은 천연고무와 스티렌 부타디엔 고무를 원료고무로 하고 기타 공지의 첨가제를 포함하는 타이어 검 체파용 고무조성물로서, 상기 원료고무에 부타디엔 고무 20∼40phr가 혼합된 검 체파용 고무조성물을 포함한다.The present invention is a rubber composition for tire sample wave containing natural rubber and styrene butadiene rubber as a raw material rubber and other known additives, and includes a rubber composition for sowing wave in which 20 to 40 phr of butadiene rubber is mixed with the raw material rubber.

부타디엔 고무는 천연고무와 적량 대체 적용되어 검 체파에서 요구하는 마모 및 발열특성을 개선한다. 바람직하기로는 부타디엔 고무는 20∼40phr의 범위에서첨가되어지는데 20phr 미만에서는 첨가에 따른 효과가 미미하며, 40phr을 초과하는 경우에는 마모 및 발열 특성의 개선은 가능하지만 반대 급부로 물성하락이 큰 단점이 있다.Butadiene rubber is applied as a substitute for natural rubber to improve the wear and heating properties required by the sample wave. Preferably, butadiene rubber is added in the range of 20 to 40 phr, but the effect of addition is less than 20 phr. If it exceeds 40 phr, wear and exothermic properties can be improved, but there is a big disadvantage of deterioration in physical properties. have.

이 경우 물성하락을 방지하기 위한 방안으로 소정의 카본블랙을 적용하는 것이 바람직하다. 상기 조건을 만족하는 카본블랙의 예로는 HAF(High Abrasion Furnace), HAF-HS(High Abrasion Furnace High Structure)를 들 수 있으며, 바람직하기로는 65∼80 phr의 범위에서 첨가하는 것이 좋으며 보다 바람직하기로는 70∼73 phr을 첨가한다. 상기와 같이 카본블랙의 함량에 제한을 두는 이유는 65 phr미만에서는 원하는 효과를 기대하기 곤란하고, 80 phr을 초과하는 경우에는 물성은 개선되지만 발열 및 점도 상승으로 인해 공정성이 하락하는 문제가 있기 때문이다.In this case, it is preferable to apply a predetermined carbon black as a method for preventing the physical property decline. Examples of the carbon black that satisfies the above conditions include HAA (High Abrasion Furnace) and HAF-HS (High Abrasion Furnace High Structure), preferably in the range of 65 to 80 phr, and more preferably Add 70-73 phr. The reason for limiting the content of the carbon black as described above is that it is difficult to expect the desired effect at less than 65 phr, and if it exceeds 80 phr, the physical properties are improved, but there is a problem that the fairness decreases due to heat generation and viscosity increase. to be.

본 발명은 또한 체파 고무조성물내의 공기 혼입에 따른 불량률을 개선하기 위한 방안으로 TR을 10∼30phr 적용한 타이어 검 체파용 고무조성물을 포함한다. 만일 상기 TR을 10 phr 미만으로 첨가하면 원하는 효과를 기대하기 곤란하며, 30phr을 초과하여 첨가하면 공기 혼입에 따른 불량률은 낮출 수 있지만 물성하락과 마모저항이 하락하는 문제가 있다.The present invention also includes a rubber sample for the tire sample wave to which 10 to 30 phr TR is applied as a way to improve the defective rate due to the mixing of air in the sowing rubber composition. If the TR is added in less than 10 phr, it is difficult to expect the desired effect, and if it is added in excess of 30 phr, the defect rate due to air mixing may be lowered, but there is a problem in that physical properties and wear resistance decrease.

또한 본 발명은 상기 설명된 고무조성물에 최적 가류를 위해 황 2.8∼3.3 phr과 활성도가 중간성능을 나타내는 가황촉진제 0.4∼0.8 phr을 함유한 검 체파용 고무조성물을 포함한다. 본 발명에서 검 체파용 고무조성물의 최적의 물성을 얻고 공정안정성을 확보하기 위해 황 2.8∼3.3 phr과 가황촉진제 0.4∼0.8 phr를 사용한다.The present invention also includes a rubber composition for sample wave containing 2.8-3.3 phr of sulfur and 0.4-0.8 phr of a vulcanization accelerator having an intermediate activity for optimum vulcanization of the rubber composition described above. In the present invention, 2.8 to 3.3 phr of sulfur and 0.4 to 0.8 phr of a vulcanization accelerator are used to obtain optimum physical properties of the rubber composition for sample wave and to secure process stability.

이하 본 발명의 내용을 실시예를 통해 구체적으로 설명하도록 한다. 그러나 다음의 실시예는 본 발명을 보다 상세하게 설명하기 위한 것으로, 본 발명의 권리 범위를 이에 한정하고자 하는 것은 아니다.Hereinafter, the contents of the present invention will be described in detail through examples.

상기 결과에 의하면 TR의 첨가로 인해 불량률이 감소됨을 알 수 있다. 다만 40 phr 이상에서는 물성 및 마모저항하락으로 바람직하지 못한 결과가 얻어졌다.According to the result, it can be seen that the defect rate is reduced due to the addition of TR. However, at 40 phr or more, unfavorable results were obtained due to a drop in physical properties and abrasion resistance.
