Description

캡플라이 기능을 겸비한 타이어 하부 트레드 고무 조성물{Tire under tread rubber composition involving the function of the cap ply}Tire under tread rubber composition involving the function of the cap ply}

본 발명은 캡플라이 기능을 겸비한 타이어 하부 트레드 고무 조성물에 관한 것으로서, 좀더 상세하게는 천연고무, 이소프렌 고무, 부타디엔 고무를 블렌드한 원료고무에 충진제로서 카본블랙과 탄성체를 첨가하므로써 내열성과 접착성이 향상된, 캡플라이 기능을 겸비한 하부 트레드 고무 조성물에 관한 것이다.The present invention relates to a tire tread rubber composition having a capply function, and more specifically, to a raw material blended with natural rubber, isoprene rubber, and butadiene rubber, by adding carbon black and an elastomer as a filler to improve heat resistance and adhesion. And a lower tread rubber composition having a cap fly function.

타이어의 하부 트레드는 외부로부터의 충격으로 인해 발생하는 발열로 인하여 상부 트레드와의 분리 현상이 일어나게 되는데, 이 분리 현상을 방지하기 위해서 상부 트레드나 하부 트레드에 발열 억제제와 결합제가 사용되고 있었다.The lower tread of the tire is separated from the upper tread due to the heat generated by the impact from the outside. An exothermic inhibitor and a binder were used in the upper tread or the lower tread to prevent the separation.

또한 종래에는 하부 트레드와 벨트와의 분리 현상을 방지하기 위해 벨트와 하부 트레드 사이에 에지 캡 플라이(edge cap ply)나 엔드리스 캡 플라이(endless cap ply)를 보강시켜 제조되었다.In addition, in order to prevent the separation of the lower tread and the belt, it was manufactured by reinforcing an edge cap ply or an endless cap ply between the belt and the lower tread.

이와 같이 벨트와의 분리 현상을 방지하기 위해서 캡 플라이를 사용하므로써, 타이어 구성 요소가 추가되고, 이로 인해 캡 플라이 공정이 추가되어 공정 비용과 재료비가 상승할 뿐만 아니라, 벨트와의 분리 방지를 완벽하게 수행할 수 없었다. 또한, 외부의 충격으로 인해 발생하는 발열을 흡수하지 못해서 상부 트레드와 하부 트레드의 분리 현상이 발생하였다.By using the cap ply to prevent separation from the belt like this, tire components are added, which adds to the cap ply process, which not only increases process cost and material cost, but also completely prevents separation from the belt. It could not be done. In addition, the separation of the upper tread and the lower tread occurred because it could not absorb the heat generated by the external impact.

그러나, 상기와 같은 문제점을 해결하기 위해서 캡 플라이를 삭제하면 벨트와의 분리 정도가 굉장히 빨라지게 되는 단점이 있었다. However, in order to solve the problem described above, the cap ply is deleted, and the degree of separation from the belt is very fast.

본 발명의 목적은 종래의 하부 트레드 고무 조성물에, 본 발명에 따라 제조된 탄성체를 첨가하므로써, 내열성과 접착성을 향상시킬 뿐만 아니라, 캡 플라이의 기능도 겸할 수 있는 하부 트레드 고무 조성물을 제공하는 것이다.It is an object of the present invention to provide a lower tread rubber composition that can not only improve heat resistance and adhesiveness but also function as a cap ply by adding an elastomer prepared according to the present invention to a conventional lower tread rubber composition. .

본 발명은 캡 플라이의 기능을 겸비한 타이어 하부 트레드 고무 조성물에 관한 것으로서, 좀더 상세하게는 기본 물성과 내열성과 접착성이 향상된 하부 트레드 고무 조성물에 관한 것이다.The present invention relates to a tire lower tread rubber composition having a function of a cap ply, and more particularly, to a lower tread rubber composition having improved basic physical properties, heat resistance and adhesion.

본 발명의 고무 조성물은 천연고무(NR) 35∼45phr, 이소프렌(IR) 고무 45∼55phr, 부타디엔 고무(BR) 15∼25phr을 블렌드한 원료고무 100phr에 대하여, 충진제로서 카본블랙 30∼50phr과 펄프 함유 탄성체 3∼10phr을 포함하는 것을 특징으로 한다.The rubber composition of the present invention is made of carbon black 30-50 phr and pulp as a filler for 100 phr of raw rubber blended with 35 to 45 phr of natural rubber (NR), 45 to 55 phr of isoprene (IR) rubber and 15 to 25 phr of butadiene rubber (BR). It is characterized by containing 3-10 phr of an elastic body.

본 발명에서 카본블랙의 함량이 30phr 미만이면 보강재로서의 물성향상 효과가 미흡하고, 50phr을 초과하면 고무 조성물에의 분산성이 나빠질 우려가 있다.In the present invention, when the content of carbon black is less than 30 phr, the effect of improving physical properties as a reinforcing material is insufficient, and when it exceeds 50 phr, dispersibility into the rubber composition may be deteriorated.

본 발명에서 펄프 함유 탄성체의 함량이 3phr 미만이면 벨트와의 접착력 향상 효과가 미흡하고, 10phr을 초과하면 다른 물성의 저하를 가져올 수 있으므로 바람직하지 않다.In the present invention, if the content of the pulp-containing elastomer is less than 3 phr, the effect of improving the adhesive strength with the belt is insufficient, and if it exceeds 10 phr, other physical properties may be reduced, which is not preferable.

본 발명에서 사용되는 탄성체(Engeneered elastomer)는 스티렌부타디엔 고무(SBR;Styrene Butadiene Rubber)에 탄성체 전체 중량 기준으로 펄프를 20∼30중량% 혼입하여 제조된 것이다. 상기 탄성체는 펄프를 황산에 담그어 펄프가 배향성을 갖게한 후, 스티렌부타디엔 고무에 펄프를 20~30중량% 혼입하여 마스터 배치화하므로써 제조된다. 이때, 펄프의 함량이 20중량% 미만이면 첨가에 따른 효과가 미흡하고, 30중량%를 초과하면 분산성이 나빠져 바람직하지 않다.The elastomer used in the present invention (Engeneered elastomer) is prepared by incorporating 20 to 30% by weight of pulp on the basis of the total weight of the elastomer in styrene butadiene rubber (SBR; Styrene Butadiene Rubber). The elastic body is prepared by dipping the pulp in sulfuric acid to give the pulp an orientation, and mixing the pulp with 20 to 30% by weight of styrenebutadiene rubber to prepare a master batch. At this time, if the content of the pulp is less than 20% by weight, the effect of the addition is insufficient, and if it exceeds 30% by weight dispersibility is bad, it is not preferable.

이하, 본 발명을 하기의 실시예 및 비교예에 의하여 보다 구체적으로 설명한다. 하기의 실시예는 본 발명을 예시하기 위한 예에 지나지 않으며 본 발명의 보호범위를 제한하고자 하는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the following Examples and Comparative Examples.
