Description

탄소나노 튜브를 이용한 정전기방지용 실리카트레드 고무조성물{Silica Tread Rubber Composition with Carbon Nano Tube}Silica Tread Rubber Composition with Carbon Nano Tube

본 발명은 탄소나노 튜브를 이용한 정전기방지용 실리카트레드 고무조성물에 관한 것으로, 좀더 상세하게는 정전기 발생의 방지가 가능하도록 전기전도성이 탁월한 탄소나노 튜브를 실리카트레드 고무조성물에 첨가하여 정전기 발생을 개선시킨 실리카트레드 고무조성물에 관한 것이다.The present invention relates to an antistatic silica tread rubber composition using carbon nanotubes, and more particularly, to improve the generation of static electricity by adding a carbon nanotube having excellent electrical conductivity to a silica tread rubber composition to prevent generation of static electricity. It relates to a tread rubber composition.

종래에는 실리카트레드의 정전기 방지 및 전기전도성을 높이기 위하여 전기전도성이 뛰어난 전도성 카번블랙을 일정량 이상 사용하거나, 정전기 발생을 억제하는 대전방지제를 사용하거나 실리카트레드의 일부를 카본블랙으로 충진된 고무조성물로 구성하거나, 정전기를 방출할 수 있도록 타이어의 구조변경을 하는 경우가 대부분이었다.Conventionally, in order to increase the antistatic and electrical conductivity of silica tread, conductive carbon black having excellent electrical conductivity is used for a certain amount, an antistatic agent that suppresses the generation of static electricity, or a part of the silica tread is composed of a rubber composition filled with carbon black. In many cases, the tires have been restructured to discharge static electricity.

그러나, 실리카의 사용량이 많아지거나, 충진제 전체를 실리카로만 사용할 경우 상기와 같은 방법을 이용하더라도 정전기 발생 방지효과가 급격히 떨어지는 문제점이 있었다.However, when the amount of silica used increases or when the entire filler is used only as silica, there is a problem in that the antistatic effect is rapidly decreased even when using the above method.

즉, 트레드 고무조성물에 일정량 이상의 실리카를 사용할 경우에는 실리카 자체의 강한 극성과 높은 전기저항으로 인해 정전기가 발생하고, 또한 발생된 정전기가 실리카의 낮은 전기전도성으로 인하여 지면으로 방출되지 못하는 문제점이 있으며, 자동차에서 발생하는 정전기도 타이어를 통해 지면으로 방출하는 기능이 떨어져 전자장치를 많이 사용하고 있는 최근의 자동차에 있어서는 심각한 문제를 야기시킬 가능성이 매우 높은 실정이다. That is, when a certain amount of silica is used in the tread rubber composition, static electricity is generated due to the strong polarity and high electrical resistance of the silica itself, and the generated static electricity is not released to the ground due to the low electrical conductivity of silica. The static electricity generated in automobiles also has a poor ability to discharge tires to the ground, which is very likely to cause serious problems in recent automobiles that use a lot of electronic devices.

본 발명자는 상기와 같은 문제점을 해결하기 위한 지속적인 연구를 수행하여 공지의 실리카트레드 고무조성물에 정전기 발생방지가 가능하도록 전기전도성이 뛰어난 탄소나노 튜브를 첨가함으로써 정전기 발생문제를 획기적으로 개선할 수 있음을 알아내고 본 발명을 완성하였다. The inventors have carried out continuous research to solve the above problems by adding a carbon nanotube having excellent electrical conductivity to prevent the generation of static electricity in the known silica tread rubber composition can significantly improve the static electricity generation problem It was found and completed the present invention.

따라서, 본 발명의 목적은 탄소나노 튜브를 함유하여 정전기의 발생을 방지할 수 있는 실리카트레드 고무조성물을 제공함에 있다. Accordingly, an object of the present invention is to provide a silica tread rubber composition that can contain carbon nanotubes to prevent the generation of static electricity.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로 공지의 첨가제와 실리카를 포함하는 실리카트레드 고무조성물에 있어서, 원료고무 100 중량부에 대하여 탄소나노 튜브 0.1∼10 중량부를 함유함을 특징으로 하는 정전기 방지용 실리카트레드 고무조성물을 제공한다.The present invention, in the silica tread rubber composition containing a known additive and silica as a means for achieving the above object, electrostatic characterized in that it contains 0.1 to 10 parts by weight of carbon nanotubes with respect to 100 parts by weight of the raw material rubber Provided is a silica tread rubber composition for prevention.

본 발명에 사용되는 원료고무로는 합성고무 또는 천연고무와 합성고무의 혼합물로 된 배합고무 어느 것이나 사용이 가능하고, 실리카의 함량비율은 원료고무 100 중량부에 대하여 10∼100 중량부 및 탄소나노 튜브의 함량비율은 원료고무 100 중량부에 대하여 0.1∼10 중량부가 바람직하다.As the raw material rubber used in the present invention, any one of synthetic rubber or a compound rubber composed of a mixture of natural rubber and synthetic rubber can be used, and the content of silica is 10 to 100 parts by weight and carbon nano based on 100 parts by weight of raw rubber. The content ratio of the tube is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the raw material rubber.

If the content is less than 0.1 parts by weight, the electrical conductivity is not improved, and if the content is more than 10 parts by weight, the effect of increasing the content is reduced and may adversely affect the properties of the rubber such as tensile strength and hardness.

본 발명에 사용되는 탄소나노 튜브는 적은 량으로도 넓은 면적에 분산시킬 수 있으며, 분산된 탄소나노 튜브는 그 끝이 서로 맞닿아 하나의 커다란 도체 그물망을 형성하게 됨으로써 발생된 정전기를 용이하게 방출할 수 있게 된다.The carbon nanotubes used in the present invention can be dispersed in a large area with a small amount, and the dispersed carbon nanotubes can easily discharge the static electricity generated by their ends contacting each other to form one large conductor mesh. It becomes possible.

상기 결과에서 보듯이 본 발명에 의한 정전기 방지용 실리카트레드 고무조성물은 탄소나노 튜브를 적적량 이상 사용함으로써 전기전도도 특성이 획기적으로 개선됨을 알 수 있고, 기타 가황특성 및 인장물성에는 별다른 영향이 없음을 알 수 있다.As can be seen from the above results, the antistatic silica tread rubber composition according to the present invention can be seen that the electrical conductivity is significantly improved by using more than the appropriate amount of carbon nanotubes, there is no significant effect on other vulcanization characteristics and tensile properties.
