Description

타이어 트레드용 고무 조성물{Rubber composition for tire tread} Rubber composition for tire treads

본 발명은 타이어 트레드용 고무 조성물에 관한 것으로서, 보다 상세하게는 고무 조성물의 경량화 및 보강성을 향상시켜 친환경적인 타이어 트레드용 고무 조성물에 관한 것이다. The present invention relates to a rubber composition for tire treads, and more particularly, to an environment-friendly tire tread rubber composition by improving the light weight and reinforcement of the rubber composition.

최근의 자동차 저연비화 추세에 따라 타이어 회전저항의 감소를 통한 저연비 타이어 개발이 주요 관심사항이며, 이를 실현하기 위해 실리카를 타이어 트레드 고무에 사용하는 기술들이 지속적으로 개발되고 있다.With the recent trend of low fuel consumption of automobiles, the development of low fuel consumption tires by reducing tire rolling resistance is a major concern, and technologies for using silica in tire tread rubber have been continuously developed to realize this.

타이어 트레드 고무의 충전제로 널리 사용되어 오던 카본블랙이 비극성인 것과 달리 실리카의 경우 표면화학적 특성이 극성이므로 비극성인 고무에 분산이 용이하지 않아 가공성 측면에서 카본블랙에 비해 불리한 측면이 있었다. Unlike carbon black, which has been widely used as a filler for tire tread rubber, silica has a surface chemical property of polarity, so it is not easy to disperse in nonpolar rubber, and thus has a disadvantage in terms of processability.

한편, 이와 같은 분산성의 문제를 해결하기 위하여 실리카 표면의 친유성화 및 고무와 실리카의 화학적 결합을 유도하기 위하여 실란계 커플링제를 대표적으로 사용하고 있다.On the other hand, in order to solve this problem of dispersibility, a silane coupling agent is typically used to induce lipophilic silica surface and chemical bonding of rubber and silica.

실란 커플링제는 실리카의 실라놀기와 반응하여 실리카의 극성인 표면화학적 특성을 비극성으로 바꾸어 고무와의 혼합이 용이하게 해주는 역할을 한다. The silane coupling agent reacts with the silanol groups of the silica to change the polar surface chemical properties of the silica to non-polarity to facilitate mixing with the rubber.

그러나, 실란계 커플링제는 고가의 물질로 비용적 측면에서 불리할 뿐만 아니라, 실리카 표면의 하이드록실기와 실란계 커플링제의 알콕실기가 반응하여 알코올을 부산물로서 배출하게 되므로 카본블랙을 충진제로 사용한 배합고무 대비 탄화수소 배출량이 많은 문제점이 있다.However, the silane coupling agent is an expensive material and is disadvantageous in terms of cost, and since the hydroxyl group on the silica surface and the alkoxyl group of the silane coupling agent react to release alcohol as a by-product, carbon black is used as a filler. There are many problems with hydrocarbon emissions compared to compound rubber.

또한, 실리카와 실란 커플링제의 충분한 반응을 위해서는 배합공정에서 온도 및 시간을 적절히 조절해주어야 한다는 문제점도 갖고 있다.In addition, in order to sufficiently react the silica and the silane coupling agent, there is a problem in that the temperature and time must be properly adjusted in the compounding step.

한편, 타이어 트레드 고무 조성물에 있어서 종래에도 결정성 제올라이트(zeolite)를 사용한 경우가 있으나 이는 적용 범위가 빙상 노면에서의 제동성능을 향상시키기 위한 것에 불과한 뿐이었다.On the other hand, in the tire tread rubber composition, crystalline zeolite may be used in the related art, but this is only to improve braking performance on ice road.

구체적으로, 제올라이트를 타이어 트레드 고무 조성물에 첨가시킴으로써 고무 조성물내 기공을 확보하고, 그로 인하여 스노우 상태에서의 제동 특성을 개선시키고자 한 것일 뿐 고무 조성물의 경량화 및 보강제로서의 역할을 수행하지는 못하고 있는 실정이었다.Specifically, the zeolite was added to the tire tread rubber composition to secure pores in the rubber composition, thereby improving braking characteristics in the snow state, and thus, did not play a role in reducing the weight and reinforcing of the rubber composition. .

본 발명은 상기와 같은 문제점을 해결하기 위해 창출된 것으로서, 종래 통상적으로 사용되는 보강제인 실리카 및 카본블랙을 다공성 제올라이트로 대체하여 타이어 트레드 고무 조성물의 경량화 및 보강성 향상을 제공하는 것을 그 목적으로 한다. The present invention has been made to solve the above problems, and its object is to replace the conventionally used reinforcing agent silica and carbon black with a porous zeolite to provide a lighter weight and improved reinforcement of the tire tread rubber composition. .

본 발명의 다른 목적 및 장점들은 하기에 설명될 것이며, 본 발명의 실시예에 의해 알게 될 것이다. 또한, 본 발명의 목적 및 장점들은 특허청구범위에 나타낸 수단 및 조합에 의해 실현될 수 있다. Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

본 발명에 따른 타이어 트레드용 고무 조성물은 원료고무와 나노기공을 갖는 제올라이트를 포함한다.The rubber composition for tire treads according to the present invention includes a raw material rubber and a zeolite having nanopores.

상기 원료고무는 통상적으로 트레드 고무 조성물에 사용되는 것이면 무방하고, 바람직하게는 폴리이소프렌 고무, 폴리부타디엔 고무, 공액 디엔 방향족 비닐 공중합체, 니트릴 공액 디엔 공중합체, 수소화 NBR, 수소화 SBR, 올레핀 고무, 말레산으로 변형된 에틸렌-프로필렌 고무, 부틸 고무, 이소부틸렌과 방향족 비닐 또는 디엔모노머의 공중합체, 아크릴 고무, 이오노머, 할로겐화 고무 및 클로로프렌 고무로 이루어진 군에서 선택된 1종 이상의 혼합고무를 사용할 수 있다.The raw rubber may be used in a tread rubber composition, and preferably, polyisoprene rubber, polybutadiene rubber, conjugated diene aromatic vinyl copolymer, nitrile conjugated diene copolymer, hydrogenated NBR, hydrogenated SBR, olefin rubber, male One or more mixed rubbers selected from the group consisting of acid-modified ethylene-propylene rubbers, butyl rubbers, copolymers of isobutylene and aromatic vinyl or diene monomers, acrylic rubbers, ionomers, halogenated rubbers and chloroprene rubbers can be used.

상기 제올라이트는 보강제로서 포함되며 종래 일반적인 보강제로 사용되고 있는 카본블랙이나 실리카를 대체 또는 혼용하여 사용할 수 있다.The zeolite is included as a reinforcing agent and can be used by replacing or mixing carbon black or silica which is conventionally used as a general reinforcing agent.

일반적으로, 제올라이트는 실리콘과 알루미늄이 산소원자를 통해 삼차원적으로 연결되어 생성되는 일종의 무기고분자 물질로서 현재 액 250여 종류의 제올라이트가 합성되고 있으며 합성 제올라이트의 경우 단일한 상을 형성시킬 수 있어 산업적 활용면에서 효과가 우수한 것으로 알려져 있다.In general, zeolite is a kind of inorganic polymer material formed by three-dimensionally connecting silicon and aluminum through oxygen atoms. Currently, about 250 kinds of liquid zeolites are synthesized. In the case of synthetic zeolites, a single phase can be formed for industrial use. It is known to be excellent in terms of effectiveness.

이와 같은 제올라이트는 합성세제에 가장 폭 넓게 사용되고 있으며 건축 첨가제로도 사용되고 있으나 타이어의 경량화 및 보강성 향상을 위해서는 사용되지 못하고 있는 실정이다. Such zeolites are most widely used in synthetic detergents and are also used as building additives, but are not used to reduce the weight and reinforcement of tires.

본 발명의 보강제로서 사용되는 제올라이트는 합성제올라이트이고, 5.5 내지 10 ㎛ 크기의 미세 결정 구조를 나타내며 0.8 내지 1.3 nm의 나노세공을 가지고 있다. 나노세공의 크기가 0.8 nm 미만일 경우에는 경량화 효과를 나타내기 어렵고, 1.3 nm 를 초과할 경우에는 제조상의 곤란성이 존재한다.The zeolite used as the reinforcing agent of the present invention is a synthetic zeolite, exhibits a fine crystal structure of 5.5 to 10 μm in size and has nanopores of 0.8 to 1.3 nm. If the size of the nanopore is less than 0.8 nm, it is difficult to exhibit a lightening effect, and if it exceeds 1.3 nm, manufacturing difficulties exist.

한편, 상기 제올라이트는 원료고무 100 중량부에 대하여 45 내지 70중량부로 포함되는바, 45중량부 미만일 경우에는 경량화에 미치는 효과가 미약한 문제점이 있고, 70 중량부 초과하여 사용할 경우에는 분산에 영향을 주어 마모성능이 떨어지는 문제점이 있다.On the other hand, the zeolite is contained in 45 to 70 parts by weight based on 100 parts by weight of the raw material rubber, when less than 45 parts by weight has a weak effect on the weight reduction, when used in excess of 70 parts by weight affects the dispersion There is a problem that the wear performance falls.

또한, 본 발명에 따른 고무 조성물은 통상적인 보강제로서 실리카 또는 카본블랙을 더 포함할 수 있는바, 원료고무 100 중량부에 대하여 50 중량부 이하로 사용되는 것이 바람직하다.In addition, the rubber composition according to the present invention may further include silica or carbon black as a conventional reinforcing agent, it is preferably used at 50 parts by weight or less with respect to 100 parts by weight of the raw material rubber.

실리카 또는 카본블랙의 함량이 50중량부를 초과하여 사용하면 동일 보강제 끼리의 응집에 따른 분산측면에서의 문제점이 발생할 수 있다.If the content of silica or carbon black is more than 50 parts by weight, problems may arise in terms of dispersion due to aggregation of the same reinforcing agents.

그리고, 상기 고무 조성물에는 통상의 첨가제로서 가류제, 가류촉진제, 노화방지제, 활성화제, 연화제 등이 필요에 따라 첨가될 수 있다.In addition, a vulcanizing agent, a vulcanization accelerator, an anti-aging agent, an activating agent, a softener, etc. may be added to the rubber composition as needed as usual additives.

상기 [표 2]의 기재를 통해 알 수 있듯이 제올라이트가 보강제로 포함된 실시예 1 및 실시예 2는 보강제로 실리카만 사용한 비교예 1에 비하여 인장물성은 동등 수준으로 유지하면서 제동 성능 및 회전저항 성능에 있어서 비교예에 비해 월등히 향상된 효과를 나타내고 있다.As can be seen from the description of Table 2, Example 1 and Example 2, in which zeolite was included as a reinforcing agent, compared to Comparative Example 1 using only silica as a reinforcing agent, the braking performance and the rolling resistance performance while maintaining the tensile properties at the same level. The effect is much improved compared to the comparative example.

또한, 타이어의 중량에 있어서도 경량화를 이룰 수 있음을 알 수 있었다.In addition, it was found that the weight of the tire can be reduced.

한편, 보강제로 제올라이트를 원료고무 100 중량부에 대하여 40 중량부로 포함한 비교예 2는 실시예 1 및 실시예 2에 비하여 인장물성, 점탄성 측면 및 경량화에 있어서 개선된 효과를 나타내고 못함을 알 수 있으며 보강제로 제올라이트를 원료고무 100 중량부에 대하여 8 중량부로 포함한 비교예 3은 실시예 1 및 실시예 2에 비하여 점탄성 및 경량화 측면에서는 우수한 효과를 나타내고 있으나 인장물성이 현저히 떨어지는 문제점이 있음을 알 수 있었다.On the other hand, Comparative Example 2 containing 40 parts by weight of zeolite as 100 parts by weight of the raw material rubber as a reinforcing agent can be seen that does not show an improved effect on the tensile properties, viscoelastic side and weight reduction compared to Examples 1 and 2 Comparative Example 3, which contains 8 wt. Parts of zeolite, based on 100 parts by weight of raw rubber, shows excellent effects in terms of viscoelasticity and light weight, compared to Examples 1 and 2, but it has been found that there is a problem in that tensile properties are significantly lower.
