Description

전도성을 개선한 실리카로 보강된 타이어용 트래드 고무조성물{Silica-filled Tread Rubber Compounds With Improved Conductivity for Tire}Silica-filled Tread Rubber Compounds With Improved Conductivity for Tire}

본 발명은 실리카로 보강된 트래드 고무조성물로서, 보다 상세하게는 트래드고무조성물의 전기전도도를 개선하기 위해 특정조건의 전도성 카본블랙을 보강충진제인 실리카와 병행적용하여 실리카 적용시 수반되는 제반물성을 유지하면서도 전도성을 개선하는 트래드 고무조성물에 관한 것이다.The present invention is a tread rubber composition reinforced with silica, and more particularly, in order to improve the electrical conductivity of the tread rubber composition, the conductive carbon black under specific conditions is applied in parallel with silica, which is a reinforcing filler, to maintain various properties accompanying silica application. Yet also relates to a tread rubber composition that improves conductivity.

최근 저연비 타이어의 개발이 가속화되면서 타이어 트래드에 있어서 실리카의 사용량이 나날이 증가하고 있다. 하지만 실리카는 절연체로서 주행 중 발생하는 마찰에 의한 전기를 외부로 방출하지 못하여 소비자로 하여금 불쾌감을 유발하는 등 많은 문제점을 낳고 있다.Recently, as the development of low-fuel tires is accelerated, the use of silica in tire treads is increasing day by day. However, silica is an insulator, which does not discharge electricity due to friction generated during driving to the outside, causing a lot of problems such as causing discomfort to consumers.

일반적으로 카본블랙을 적용한 트래드의 경우에는 체적저항율이 108Ω·cm이거나 그 이하인 반면 실리카를 100% 적용한 경우 1013Ω·cm 이상의 매우 높은 전기저항성을 가지게 되어 전도성을 전혀 발휘할 수 없다.In general, when the carbon black is applied to the tread, the volume resistivity is 10 8 Ω · cm or less, whereas when 100% of the silica is applied, the tread has very high electrical resistivity of 10 13 Ω · cm or more and thus cannot exhibit any conductivity.

따라서 실리카가 지니는 상기 단점을 보완하기 위해 카본블랙을 병용적용하는 경우 통상적으로 30phr 정도 이상의 고농도의 첨가가 요구되며 이 경우 어느 정도의 전기전도성을 발휘할 수는 있지만 실리카 첨가로 인해 얻을 수 있는 물성의 하락을 초래하게 되므로 카본블랙의 첨가량에는 한계가 존재하게 되는 문제가 발생한다.Therefore, in order to supplement the above disadvantages of silica, when carbon black is used in combination, a high concentration of 30 phr or more is usually required. This causes a problem that a limit exists in the amount of carbon black added.

본 발명자는 상기와 같은 종래기술이 지니는 한계를 극복하기 위한 방안을 강구하여 오던 중 소량의 첨가로도 전도성을 발휘할 수 있으며 실리카와 병용적용시 실리카가 지니는 고유한 물성의 하락을 유발하지 아니하면서도 전기전도성을 충분히 발휘할 수 있는 카본블랙을 적량첨가한다면 상기 문제를 해결함이 가능하다는 점에 착안하여 본 발명을 완성하게 되었다.The present inventors have been devised to overcome the limitations of the prior art as described above, and can exhibit conductivity even with the addition of a small amount of electricity. The present invention has been completed by focusing on the appropriate addition of a carbon black capable of sufficiently exhibiting conductivity.

따라서 본 발명의 목적은 회전저항성과 제동성 등의 물성의 하락이 수반됨이 없으면서 전기전도성을 발휘함이 가능한 트래드 고무조성물을 제공함에 있다.It is therefore an object of the present invention to provide a tread rubber composition capable of exhibiting electrical conductivity without accompanied by a drop in physical properties such as rotational resistance and braking properties.

본 발명은 실리카로 보강된 트래드 고무조성물로서, 트래드 고무조성물의 전기전도도를 개선하기 위해 표면적이 500∼1200mg/g, DBP흡착가가 150∼400㎖/100g인 전도성 카본블랙을 보강충진제인 실리카와 병행적용함을 특징으로 하는 트래드고무조성물을 포함한다.The present invention is a tread rubber composition reinforced with silica, and in order to improve the electrical conductivity of the tread rubber composition, the conductive carbon black having a surface area of 500 to 1200 mg / g and a DBP adsorption value of 150 to 400 ml / 100 g is combined with silica as a reinforcing filler. Tread rubber compositions characterized by application.

상기 구성에 의한 트래드 고무조성물은 카본블랙의 함량을 소량으로 하면서도 실리카가 지니는 특징적 물성을 그대로 유지함이 가능하고 또한 전도성 카본블랙을 적용함에 따른 전도성의 개선은 트래드 고무조성물에서 요구되는 바람직한 특성을 제공하기에 충분하다.The tread rubber composition according to the above configuration can maintain the characteristic properties of silica while having a small amount of carbon black, and the improvement of conductivity by applying conductive carbon black provides desirable properties required in the tread rubber composition. Is enough.

전도성 카본블랙은 일반 카본블랙과는 달리 그 구조가 긴 사슬처럼 되어 있어 이들을 고무에 배합할 경우 카본블랙 입자가 연쇄구조를 형성하고, 상기 형성된 연쇄를 통해 파이전자가 이동하여 전기를 도통시키거나, 카본블랙 입자간을 파이전자가 점프(jump)하는 방법에 의해 전도성을 부여하는 것으로 알려져 있다(일반적으로 점프를 위한 카본블랙간의 입자간 거리는 100Å 이하인 것으로 알려져 있다).Unlike carbon black, conductive carbon black has a long structure, and when blended with rubber, carbon black particles form a chain structure, and the pi electrons move through the formed chain to conduct electricity. It is known to impart conductivity by a method in which pi electrons jump between carbon black particles (generally, the distance between particles between carbon blacks for jumping is known to be 100 kPa or less).

따라서 전도성은 카본블랙의 입자경이 작을수록 고무 매트리스상에서 입자간의 거리가 짧아져 도전통로의 역할이 증가하기 때문에 증가하게 되며, 또한 구조가 발달할수록 카본블랙 애그리게이트(aggregate)의 비등축성 및 형상의 불규칙성이 강하여 전도성이 우수하게 된다.Therefore, the conductivity increases as the particle diameter of the carbon black is shorter, and the distance between particles on the rubber mattress becomes shorter, and the role of the conductive passage increases. Also, as the structure is developed, the non-axiality and shape irregularity of the carbon black aggregate are increased. This is strong and the conductivity is excellent.

본 발명에 적용하는 전도성 카본블랙은 상기 조건을 만족하기 위해 표면적이 500∼1200mg/g, DBP흡착가가 150∼400㎖/100g인 전도성 카본블랙을 보강충진제인 실리카와 병행적용한다. 만일 표면적이 500mg/g 미만인 경우에는 입자간 거리가 충분히 짧지 못하게 되고, 1200mg/g을 초과하게 되면 배합시 분산성이 좋지 않기 때문에 바람직하지 아니하다.In order to satisfy the above conditions, the conductive carbon black applied to the present invention is applied to the conductive carbon black having a surface area of 500 to 1200 mg / g and a DBP adsorption value of 150 to 400 ml / 100 g in parallel with silica as a reinforcing filler. If the surface area is less than 500 mg / g, the distance between particles is not sufficiently short, and if it exceeds 1200 mg / g, it is not preferable because the dispersibility is poor at the time of compounding.

또한 DBP흡착가가 150㎖/100g 미만이면 구조가 발달되지 않아 전도성이 저하되고, 400㎖/100g 초과하게 되면 고가의 카본블랙을 사용하게 되어 제조원가가 상승하여 바람직하지 아니하다.In addition, if the DBP adsorption value is less than 150ml / 100g, the structure is not developed, the conductivity is lowered, and if it exceeds 400ml / 100g, expensive carbon black is used to increase the manufacturing cost, which is undesirable.

본 발명에 의한 트래드 고무조성물은 상기와 같은 특성의 전도성 카본블랙을 적용함으로써 종래의 일반 카본블랙에 비해 소량 적용하는 것으로도 원하는 물성 및 전도성의 확보가 가능하다. 따라서 원료고무대비 30phr이하를 적용함에 의해서도 원하는 효과를 얻는 것이 가능하다.The tread rubber composition according to the present invention can secure desired properties and conductivity even by applying a small amount of the conventional carbon black by applying the conductive carbon black having the above characteristics. Therefore, it is possible to obtain the desired effect by applying less than 30phr compared to the raw material rubber.

기타 본 발명의 트래드 고무조성물을 구성하는 제반성분은 공지의 것을 그대로 적용하는 것이 가능하므로 이들 성분에 관한 설명은 생략하기로 한다.Other components constituting the tread rubber composition of the present invention can be applied as it is well known as such, the description of these components will be omitted.

이하 본 발명의 내용을 하기 실시예를 통해 구체적으로 설명하기로 하나 본 발명의 권리범위가 이들 실시예에 한정되는 것은 아니다.Hereinafter, the contents of the present invention will be described in detail with reference to the following examples, but the scope of the present invention is not limited to these examples.
