Description

정전기 방지용 트레드 고무조성물Antistatic Tread Rubber Composition

본 발명은 정전기 방지용 트레드 고무조성물에 관한 것으로, 좀더 상세하게는 실리카가 충진된 트레드 고무조성물에 알루미늄 파우더를 변량 첨가하여 전기전도도가 향상된 타이어의 전기전도성 트레드 고무조성물에 관한 것이다.The present invention relates to an antistatic tread rubber composition, and more particularly, to an electrically conductive tread rubber composition of a tire having improved electrical conductivity by adding aluminum powder to a silica-filled tread rubber composition.

저연비 성능 및 젖은 노면접지 성능을 갖는 타이어를 제조하기 위하여 카본블랙 보다 전기적 절연체인 실리카의 사용량이 나날이 증가하고 있는 추세이다.In order to manufacture tires having low fuel efficiency and wet road surface grounding, the amount of silica, which is an electrical insulator, is increasing day by day.

기존의 승용차용 타이어 트레드 고무조성물의 주된 구성물질로 사용되는 카본블랙은 전기전도체로서 방전성능을 갖고 있지만, 젖은 노면접지 성능, 저연비 성능, 내마모성능 등의 특성을 갖는 고무조성물을 제조하기 위하여 다량의 실리카가 사용되고 있는 추세이다. 이와 같은 전기적 절연체인 실리카가 주된 보강제로 사용될 경우, 그 고무조성물의 물성은 실리카의 영향으로 전기적 절연성을 갖게 된다. 전기적 절연성을 갖는 고무조성물은 타이어와 같은 마찰이 심한 용도로 사용될 경우, 정전기 문제를 야기시키는 문제점이 있다. 타이어의 마찰에 의해 유도된 정전기는 자동차 문의 개폐시 불괘감을 유발시키고, 주유중 화재를 야기기킬 수 있다.Carbon black, which is used as the main constituent of tire tread rubber compositions for passenger cars, has discharge performance as an electric conductor, but it has a large amount of rubber composition for manufacturing wet road surface performance, low fuel consumption performance and wear resistance performance. Silica is being used. When silica, which is an electrical insulator, is used as a main reinforcing agent, the physical properties of the rubber composition have electrical insulation due to the influence of silica. Rubber compositions having electrical insulation have a problem of causing electrostatic problems when used in heavy friction applications such as tires. Static electricity induced by the friction of tires may cause malaise when opening and closing a car door and may cause a fire during fueling.

따라서, 실리카를 사용하여 고성늘의 타이어 제조를 위해서는 실리카 사용에 따른 정전기 장애를 해소할 수 있는 대안이 필수적으로 존재하여야 한다.Therefore, for the manufacture of tires of high quality using silica, there must be an alternative that can solve the static interference caused by the use of silica.

본 발명자 들은 상기의 문제점을 해결하고자 연구를 수행하던 중, 실리카와 같은 전기적 절연성 물질을 충진제로한 트레드 고무조성물에 알루미늄 파우더를 변량 첨가하여 전기전도성을 향상시키므로 주행시 발생되는 차량의 정전기 문제를 해결할 수 있음을 알아내고 본 발명을 완성하였다.The inventors of the present invention, while conducting research to solve the above problems, by adding a variable amount of aluminum powder to the tread rubber composition filled with an electrically insulating material such as silica to improve the electrical conductivity can solve the static electricity problem of the vehicle generated during driving. It was found that the present invention was completed.

따라서, 본 발명의 목적은 전기적 절연체인 실리카가 충진된 트레드 고무조성물에 높은 전기전도성을 갖는 소량의 알루미늄 파우더를 첨가하여 트레드 고무조성물의 고유물성을 유지하면서 전기전도성이 향상된 트레드 고무조성물을 제공함에 있다.Accordingly, an object of the present invention is to provide a tread rubber composition having improved electrical conductivity while adding a small amount of aluminum powder having high electrical conductivity to a silica-filled tread rubber composition which is an electrical insulator. .

즉, 본 발명은 보강제로 실리카 30-75 phr과 카본블랙 3-35 phr이 함유된 트레드 고무조성물에 3.5-5.5 phr의 알루미늄 파우더가 첨가된 정전기 방지용 트레드 고무조성물임을 특징으로 한다.That is, the present invention is characterized in that the antistatic tread rubber composition to which aluminum powder of 3.5-5.5 phr is added to the tread rubber composition containing 30-75 phr of silica and 3-35 phr of carbon black as a reinforcing agent.

본 발명은 실리카와 같은 전기적 절연성 물질을 충진물로하여 제조된 트레드 고무조성물의 전기전도성을 향상시키므로 주행시 발생되는 차량의 정전기 문제를 해결하기 위한 트레드 고무조성물에 관한 것이다.The present invention relates to a tread rubber composition for solving the electrostatic problem of the vehicle generated during driving because it improves the electrical conductivity of the tread rubber composition prepared by using an electrically insulating material such as silica.

실리카가 고무조성물의 보강제로 사용될 경우, 고무조성물은 실리카의 영향을 받아 전기적 절연체의 성질을 갖게 된다. 여기에 소량의 알루미늄 파우더를 변량 첨가하면 전기전도성은 매우 향상되면서, 주된 물성인 인장강도, 동적 점탄성이 실리카 만 보강제로 사용된 고무조성물과 유사하게 된다.When silica is used as a reinforcing agent of the rubber composition, the rubber composition has the properties of an electrical insulator under the influence of silica. When a small amount of aluminum powder is added thereto, the electrical conductivity is greatly improved, and the main physical properties such as tensile strength and dynamic viscoelasticity are similar to those of a rubber composition used only as a silica reinforcing agent.

본 발명에 사용되는 주요 원재료는 용액중합 SBR, 카본블랙, 실리카(silica) 및 알루미늄 파우더로서, 실리카가 충진된 트레드 고무조성물에 알루미늄 파우더를 변량 첨가하여 전기전도도가 향상된 트레드 고무조성물을 제조할 수 있다.The main raw materials used in the present invention are solution polymerization SBR, carbon black, silica (silica) and aluminum powder, it is possible to manufacture a tread rubber composition with improved electrical conductivity by adding aluminum powder to the tread rubber composition filled with silica. .

실리카 만을 보강제로 사용한 트레드 고무조성물에 소량의 알루미늄 파우더를 첨가하면 전기전도성이 크게 향상되어 방전성을 갖게 되고, 또한 실리카의 양이 감소할 때 알루미늄 파우더의 양 또한 소량을 사용할 경우에도 전기전도성이 우수하게 된다. 따라서, 소량의 알루미늄 파우더를 사용하여 방전성이 매우 우수한 고무조성물을 제조할 수 있다.When a small amount of aluminum powder is added to the tread rubber composition using only silica as a reinforcing agent, the electrical conductivity is greatly improved and the discharge property is increased. Also, when the amount of silica is decreased, the amount of aluminum powder is also excellent in the electrical conductivity. Done. Thus, a small amount of aluminum powder can be used to produce a rubber composition having excellent discharge characteristics.

본 발명에 사용되는 실리카의 양은 30-75 phr, 카본블랙의 양은 3-35 phr을 알루미늄 파우더는 200 메쉬 정도의 일반 알루미늄 파우더를 3.5-5.5 phr 사용하는 것이 바람직하다.The amount of silica used in the present invention is preferably 30-75 phr, the amount of carbon black is 3-35 phr, and the aluminum powder is preferably about 200 mesh to 3.5-5.5 phr.
