Description

타이어용 고무조성물{Rubber composition for tire}Rubber composition for tires

본 발명은 타이어용 고무조성물에 관한 것으로서 보다 상세하게는 폐타이어에서 발생하는 고무분말과 타이어 제조과정 중 발생하는 미가류 폐고무를 포함하는 것을 특징으로 하는 타이어용 고무조성물에 관한 것이다.The present invention relates to a rubber composition for a tire, and more particularly, to a rubber composition for a tire, characterized in that it comprises rubber powder generated from waste tires and unvulcanized waste rubber generated during a tire manufacturing process.

생활수준이 향상됨에 따라 자동차의 생산이 증가되고 자동차 생산의 증가는 타이어의 수요 역시 증가시키고 있으며 이러한 타이어의 수요 증가에 따라 폐타이어의 발생 또한 증가하고 있다.As the standard of living improves, the production of automobiles increases, and the increase of automobile production also increases the demand for tires. As the demand for such tires increases, the generation of waste tires also increases.

종래 폐타이어의 처리는 군부대에서의 진지공사 또는 도로의 방호벽으로 사용되거나 잘게 분해하여 땅에 매립하는 방법이 주로 이용되었으나 군부대 및 도로에서의 폐타이어 수요가 점차 줄어들면서 땅에 매립하는 방법이 주로 이용되고 있다.Conventionally, the disposal of waste tires has been mainly used as a groundbreaking work in military units or as road barriers or to dismantle them into land, but landfilling is mainly used as the demand for waste tires in military units and roads decreases gradually. It is becoming.

땅에 매립하는 폐타이어의 처리는 점차 환경문제로 대두되고 있으면 이러한 문제는 사회적인 문제로 확대되어 세계 각국에서는 폐타이어 처리에 관한 각종 법률이나 규제를 제정하여 이를 준수토록 함과 동시에 폐타이어가 환경에 미치는 제반 영향이나 폐타이어 처리 방안 등의 연구에 재정적인 지원을 하고 있다.If the disposal of waste tires on land becomes an environmental issue, these problems will be extended to social issues, and countries around the world will enact and comply with various laws and regulations on disposal of waste tires. It is providing financial support for researches on the impacts and disposal of waste tires.

이러한 배경하에 각종 환경 보건 측면에서의 영향을 최소화하고 갈수록 고갈되고 있는 자원의 보존 측면에서도 폐타이어를 하나의 자원으로 인식하고 재활용 방안을 찾고자 하는 노력들이 현재 활발히 진행되고 있다.Under these circumstances, efforts are being made to recognize waste tires as a resource and to find a recycling method in terms of minimizing the impact on various environmental health aspects and preserving increasingly exhausted resources.

폐타이어의 재활용은 크게 열 이용, 원형 이용, 분말가공 이용과 같이 크게 세 가지 방법으로 분류할 수 있는데 이중 분말가공은 폐타이어를 분쇄하여 분말화 한 후 사용하는 것으로 그 적용분야가 열 이용, 원형 이용 보다 광범위하다.The recycling of waste tires can be classified into three main methods: heat use, circle use, and powder processing. Double powder processing is used after grinding waste tires and pulverizing them. Extensive use.

분말가공을 이용한 폐타이어의 재활용 촉진을 위해 폐타이어의 고무분말의 특성을 향상시키고 보다 다양한 분야에 적용하기 위한 폐타이어의 분쇄방법, 고무분말의 표면처리, 탈황방법 등에 관한 활발한 연구도 진행중이고, 고무분말을 여러 분야에 적용한 결과도 보고되고 있다.In order to promote the recycling of waste tires using powder processing, active researches on the pulverization method of waste tires, surface treatment of rubber powders, desulfurization methods, etc. are being conducted to improve the properties of rubber tires and apply them to various fields. The results of applying rubber powder to various fields have also been reported.

한편 이러한 고무분말을 타이어용 고무화합물에 적용하여 타이어 제조시 원가절감이나 환경문제의 해결에 기여하고자 하는 노력이 미세한 입자 크기를 가지거나 특성이 향상된 고무분말의 출현에 따라 더욱 심도 있게 진행되고 있으나 고무분말을 타이어용 고무화합물에 적용시 원료고무와의 상용성 및 분산성의 저하, 계면에서의 접착력 결여 등에 의하여 고무화합물의 기계적 물성이 하락하게 되는 문제가 있다.On the other hand, efforts to reduce the cost of tires and to solve environmental problems by applying such rubber powders to tire rubber compounds have been carried out more deeply with the appearance of rubber powder with fine particle size or improved characteristics. When the powder is applied to a rubber compound for tires, there is a problem that the mechanical properties of the rubber compound are deteriorated due to a decrease in compatibility and dispersibility with the raw material rubber, lack of adhesion at the interface, and the like.

본 발명은 폐타이어에서 발생하는 고무분말과 타이어 제조과정 중 발생하는 미가류 폐고무를 포함하는 타이어용 고무조성물의 제공을 목적으로 한다. 또한 본 발명은 폐타이어에서 발생하는 고무분말을 타이어용 고무조성물에 포함되도록 함으로써 폐타이어의 재활용을 또다른 목적으로 한다. 한편 본 발명은 상기 폐타이어 고무분말과 미가류 폐고무를 원료고무와 예비혼합(pre-mixing)을 한 후 통상적으로 타이어 제조시 사용하는 조성물을 첨가하여 제조함으로써 타이어용 고무화합물의 물성하락을 억제하고자 한다.An object of the present invention is to provide a rubber composition for a tire comprising rubber powder generated from waste tires and unvulcanized waste rubber generated during tire production. In another aspect, the present invention is to recycle the waste tires by including the rubber powder generated from the waste tires in the rubber composition for the tire. On the other hand, the present invention pre-mixing the waste tire rubber powder and unvulcanized waste rubber with the raw material rubber (pre-mixing) to suppress the degradation of the physical properties of the rubber compound for the tire by adding a composition commonly used in the manufacture of tires I would like to.

본 발명의 타이어용 고무조성물은 스티렌-부타디엔 고무(SBR), 부타디엔 고무(BR) 또는 천연고무(NR)인 원료고무 100 phr에 대하여 폐타이어에서 발생하는 고무분말 5∼30 phr과 타이어 제조과정 중 발생하는 미가류 폐고무 5∼30 phr을 혼합하여 사용하는 것을 특징으로 한다.The rubber composition of the present invention is composed of 5 to 30 phr of rubber powder generated from waste tires with respect to 100 phr of raw rubber such as styrene-butadiene rubber (SBR), butadiene rubber (BR) or natural rubber (NR). It is characterized by using a mixture of 5 ~ 30 phr of unoccupied waste rubber generated.

상기에서 폐타이어에서 발생하는 고무분말의 입자크기는 45∼250㎛ 인 것을 사용하는 것이 좋은데 이러한 수치는 실험적으로 고무분말의 입자크기를 달리 하여 인장강도를 측정시 고무분말의 입자크기가 45∼250㎛ 인 경우의 인장강도가 가장 좋은 결과가 나왔기 때문이다.The particle size of the rubber powder generated in the waste tire is preferably used in the range of 45 ~ 250㎛. These figures are experimentally different from the particle size of the rubber powder, the particle size of the rubber powder when measuring the tensile strength 45 ~ 250 This is because the best results were obtained in terms of tensile strength in the case of µm.

한편 폐타이어에서 발생하는 고무분말 또는 미가류 폐고무는 스티렌 부타디엔 고무, 부타디엔 고무 또는 천연고무를 포함한다.On the other hand, the rubber powder or unvulcanized waste rubber generated from the waste tire includes styrene butadiene rubber, butadiene rubber or natural rubber.

이하 본 발명을 다음의 실시예에 의하여 설명하고자 한다. 그러나 이들이 본발명의 기술적 범위를 한정하는 것은 아니다.Hereinafter, the present invention will be described by the following examples. However, these do not limit the technical scope of the present invention.
