Description

정전기 방지용 트레드 고무조성물{Tread rubber composition for preventing of static electricity}Tread rubber composition for preventing of static electricity

본 발명은 정전기 방지용 트레드 고무 조성물에 관한 것으로, 보다 상세하게는 실리카를 많이 적용한 고성능 타이어의 전기적 저항을 108 Ω·Cm 이하로 유지 되도록 하는 정전기 방지용 트레드 고무조성물에 관한 것이다.The present invention relates to an antistatic tread rubber composition, and more particularly to an antistatic tread rubber composition to maintain the electrical resistance of a high-performance tire applied a lot of silica to 10 8 Ω · Cm or less.

소비자들의 요구 성능이 다양해지고 고급화 됨에 따라 타이어 제조회사들의 제품 개발에는 어려움이 가중되고 있는게 현실이다. 소비자들은 다양한 요구 특성중에서도 경제성을 중요시하고 있으며, 소비자들의 요구 이외에도 사회적인 측면에서는 환경친화성에 대한 요구는 점차 증대되어 가고 있다. 경제성 및 환경친화에 대한 요구를 충족시키기 위해 출시되는 제품들은 실리카를 적용하거나 히스테리시스 손실(Hysteresis Loss)을 감소시키는 방법을 통하여 저연비, 고내마모의 제품으로 소비자 요구 성능을 충족시키고 있다.As the performance demands of consumers are diversified and advanced, it is a fact that tire makers are developing difficulties. Consumers value economics among various demand characteristics, and in addition to consumer demands, the demand for environmental friendliness is gradually increasing in social aspects. Products that are released to meet the needs of economics and eco-friendliness are meeting the requirements of consumers with low fuel consumption, high wear resistance by applying silica or reducing hysteresis loss.

소비자의 높은 요구 성능 수준을 만족시키기 위하여 사용되어지는 재료의 일종인 실리카는 기존에 타이어 제조업체에서 일반적으로 사용하는 타이어용 충진제인 카본블랙(Carbon Black)에 비해 회전저항이나 젖은 노면에서의 제동성능 등 거의 모든 성능 면에서 우수한 특성을 가지고 있다. 이러한 재료적인 우수성 때문에 최근 고성능 타이어에는 실리카를 충진제로 사용하는 것이 일반화되고 있는게 현실이다. Silica, a kind of material used to satisfy the high level of performance required by consumers, has a higher rolling resistance and braking performance on wet roads than carbon black, a tire filler commonly used by tire manufacturers. It has excellent characteristics in almost all performances. Due to such material excellence, the use of silica as a filler for high performance tires is becoming more common.

그러나 실리카는 전기적으로 부도체의 성질을 갖고 있어 이를 타이어에 적용시 사용량이 증가할수록 부도체의 성질을 갖게 되므로 정전기적인 문제를 발생하게 된다.However, silica has the property of non-conductor electrically, and when applied to tires, the use of silica increases the nature of the non-conductor, causing electrostatic problems.

상기와 같은 문제점을 해결하기 위해, 본 발명은 전기 전도성을 갖는 재료의 사용량을 조절하여 실리카를 많이 사용한 고성능 타이어의 트레드 고무에 있어서 전기적 저항을 108 Ω·Cm 이하로 유지시킬 수 있는 타이어 트레드 고무조성물의 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention is a tire tread rubber that can maintain the electrical resistance of 10 8 Ω · Cm or less in the tread rubber of high-performance tires using a lot of silica by controlling the amount of the material having electrical conductivity It is an object to provide a composition.

본 발명의 트레드 고무조성물은 천연고무를 단독으로 사용하거나, 천연고무와 합성고무의 혼합물 및 합성고무 단독으로 사용하는 원료고무 100 중량부에 대하여 보강충진제로서 실리카를 40 중량부 적용한 경우, 역시 보강충진제의 일종인 카본블랙을 37.5 중량부 이상, 바람직하게는 37.5∼42.5 중량부 포함하도록 하여 자동차 제조회사의 요구수준인 108 Ω·Cm 이하로 전기 저항을 유지하는 트레드 고무를 제공할 수 있다.The tread rubber composition of the present invention is a reinforcing filler when 40 parts by weight of silica is used as a reinforcing filler with respect to 100 parts by weight of raw rubber using only natural rubber or a mixture of natural rubber and synthetic rubber and synthetic rubber alone. It is possible to provide a tread rubber that maintains electrical resistance at 10 8 Ω · Cm or less, which is a requirement of the automobile manufacturer, by including 37.5 parts by weight or more, preferably 37.5 to 42.5 parts by weight, of carbon black.

본 발명에서 합성고무는 스티렌 부타디엔 고무, 부타디엔 고무를 사용할 수 있으며 합성고무 단독으로 원료고무를 사용시 보다 바람직하게는 유화중합 스티렌 부타디엔 고무(E-SBR)와 용액중합 스티렌 부타디엔 고무(S-SBR)가 1:1 비율로 혼합된 혼합고무를 사용하는 것이 좋다.Synthetic rubber in the present invention may be used styrene butadiene rubber, butadiene rubber, and more preferably when the synthetic rubber alone raw material rubber, emulsion polymerization styrene butadiene rubber (E-SBR) and solution polymerization styrene butadiene rubber (S-SBR) is It is recommended to use mixed rubber mixed in a 1: 1 ratio.

상기에서 원료고무 100 중량부, 실리카를 40 중량부 적용시 카본블랙을 37.5 중량부 미만 사용하면 본 발명의 목적인 정전기 적인 문제를 해결할 수 없으며, 42.5 중량부 초과 사용하면 과량의 카본블랙 사용으로 제조공정성이 하락하는 문제가 있어 본 발명에서 카본블랙은 37.5∼42.5 중량부 사용하는 것이 좋다.When using 100 parts by weight of the raw material rubber, 40 parts by weight of silica when using less than 37.5 parts by weight of carbon black can not solve the electrostatic problem of the object of the present invention, if used more than 42.5 parts by weight of excessive carbon black manufacturing processability Since there is a problem of this decrease, it is preferable to use 37.5 to 42.5 parts by weight of carbon black in the present invention.

이하, 실시예 및 비교예를 통하여 본 발명을 보다 상세히 설명한다. 그러나, 본 발명이 이들에 의해 국한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples. However, the present invention is not limited to these.

상기 표 2의 시험결과는 유화중합 SBR와 용액중합 SBR가 1:1의 비율로 구성된 원료고무 100 중량부에 대하여 보강충진제로서 실리카를 40 중량부 적용하고, 보강충진제의 일종으로서 카본블랙 로딩량을 조금씩 달리한 물성측정결과를 보여준 것으로, 특히 측정전압(75V, 100V, 120V, 200V, 300V)에 따른 전기저항은 원료고무 100 중량부에 대하여 토탈 카본블랙 로딩량이 37.5 중량부 이상일때 모든 전압에 전기저항이 자동차 제조회사의 요구수준인 108 Ω·Cm 이하인 걸로 나타났음을 알 수 있다.The test results of Table 2 were applied to 40 parts by weight of silica as a reinforcing filler with respect to 100 parts by weight of the raw material rubber composed of the ratio of emulsion polymerization SBR and solution polymerization SBR 1: 1, and the carbon black loading amount as a kind of reinforcing filler The results of the measurement of the physical properties are different.In particular, the electrical resistance according to the measured voltage (75V, 100V, 120V, 200V, 300V) is applied to all voltages when the total carbon black loading is more than 37.5 parts by weight based on 100 parts by weight of rubber It can be seen that the resistance is less than 10 8 Ω · Cm, which is required by the automobile manufacturer.
