Description

타이어용 에이팩스 고무조성물{Apex Rubber Composition for Tire}Apex Rubber Composition for Tire

본 발명은 타이어용 에이팩스(Apex) 고무조성물에 관한 것으로 보다 상세하게는 경도를 향상시키면서도 각종 제반 물성이 개선되는 효과를 가지도록 고무조성물에 나노 보강성 수지를 적량 도입한 타이어용 에이팩스 고무조성물에 관한 것이다.The present invention relates to an apex rubber composition for a tire. More specifically, an apex rubber composition for a tire in which a nano-reinforcement resin is appropriately introduced into a rubber composition in order to have an effect of improving hardness and various physical properties. It is about.

에이팩스는 타이어의 비드부를 감싸는 고무로 구성되며 외부로부터의 충격을 완화하며, 일반적으로 고경도의 보강성이 큰 에이펙스일수록 비드부의 보강효과가 크기 때문에 고경도의 고무가 요구되고 있다.Apex is composed of a rubber wrap around the bead of the tire to mitigate the impact from the outside, in general, the higher the hardness of the reinforcement of the apex, the higher the reinforcement effect of the bead portion, the higher the hardness of the rubber is required.

이러한 요구를 만족시키기 위한 고경도의 고무를 배합하기 위해서는 통상적인 방법으로 카본블랙의 등급을 입자경이 작고 표면적이 큰 것으로 조절한다든지 동일등급의 카본블랙에서는 그 양을 증가하는 것이 일반적이고, 또 다른 방법으로 오일의 양을 감량하는 방법이 주로 사용되고 있다. 상기와 같은 방법으로는 고무 배합시 카본블랙의 분산성이 저하되며, 인장강도 등의 물성의 하락과 함께 내굴곡 특성이 떨어지고, 또한 히스테리시스 손실에 의해 발열이 증가하게 되어 전체적으로 타이어의 내구력을 하락시키게 된다. 또한 일반적으로 널리 알려진 보강성 레진을 사용한다 하더라도 경도 상승과 더불어 인장강도 등의 물성하락 및 점착력의 하락을 초래하는 문제점이 존재한다.In order to blend high hardness rubber to satisfy these demands, it is common to adjust the grade of carbon black to have a small particle size and a large surface area in a conventional manner or to increase the amount of carbon black of the same grade. As a method, a method of reducing the amount of oil is mainly used. In the above method, the dispersibility of carbon black is reduced during rubber compounding, the bending resistance decreases with the decrease of physical properties such as tensile strength, and the heat generation increases due to the hysteresis loss, thereby reducing the overall durability of the tire. do. In addition, even when the reinforcing resin is generally known, there is a problem of causing a decrease in physical properties, such as tensile strength, and a decrease in adhesive strength, in addition to increasing hardness.

본 발명자는 상기와 같이 종래 에이펙스 고무조성물이 지니는 한계를 극복하기 위한 방안으로 카본블랙 또는 오일의 양을 조절하지 않고서도 점착성과 보강성을 동시에 만족시키는 첨가물인 나노 보강성 수지를 도입하여 본 발명을 완성하게 되었다.The present inventors introduced the present invention by introducing a nano-reinforcement resin which is an additive that satisfies the adhesiveness and reinforcement at the same time without adjusting the amount of carbon black or oil in order to overcome the limitations of the conventional apex rubber composition as described above. It was completed.

따라서 본 발명의 목적은 경도를 향상시키면서 동시에 제반물성의 하락을 초래하지 않는 타이어용 에이팩스 고무조성물을 제공함에 있다. Accordingly, it is an object of the present invention to provide an afax rubber composition for tires that improves hardness and at the same time does not cause deterioration of physical properties.

본 발명은 타이어용 에이팩스 고무조성물로서, 에이팩스용으로 사용되는 통상의 원료고무 100중량부에 대해 나노 보강성 수지 1∼15중량부를 포함함을 특징으로 하는 타이어용 에이팩스 고무조성물을 포함한다.The present invention includes an afax rubber composition for a tire, comprising 1 to 15 parts by weight of a nano-reinforcement resin with respect to 100 parts by weight of a conventional raw material rubber used for an afax.

에이팩스용으로 사용되는 원료고무는 통상적으로 적용되어 오던 것이라면 충분하고 특별한 한정을 요하지는 아니한다. 일반적으로 에이팩스에 적용되는 원료고무로는 천연고무 80∼100중량부와 합성고무 20중량부 이내로 포함된 것이 이용될 수 있다.The raw material rubber used for Apex is sufficient if it has been applied in general and does not require special limitation. In general, as a raw material rubber to be applied to afax, those contained within 80-100 parts by weight of natural rubber and 20 parts by weight of synthetic rubber may be used.

본 발명에 적용되는 나노 보강성 수지는 바람직하기로는 5∼20중량부의 실리케이트와, 80∼95중량부의 수지를 함유하며, 보다 바람직하기로는 상기 실리케이트는 비중이 2.3±0.3의 범위이고, 층간높이가 1.0∼3.0nm이며, SiO2의 함량이 90 중량부 이상이다.The nano-reinforcement resin to be applied to the present invention preferably contains 5 to 20 parts by weight of silicate and 80 to 95 parts by weight of resin, more preferably the silicate has a specific gravity in the range of 2.3 ± 0.3 and the interlayer height is high. 1.0~3.0nm is, the content of SiO 2 is more than 90 parts by weight.

또한 상기 나노 보강성 수지에 포함되는 수지로는 예를 들면 합성수지계 중의 하나인 CNSL(Cashew Nut Shell Liquid)로 변성된 페놀포름알데히드 수지를 들 수 있다.In addition, the resin contained in the nano reinforcing resin may include, for example, a phenol formaldehyde resin modified with CNSL (Cashew Nut Shell Liquid), which is one of synthetic resins.

상기와 같은 구성의 나노 보강성 수지는 원료고무 100중량부에 대해 1∼15중량부로 첨가됨이 바람직한데, 이러한 이유는 만일 1중량부 미만으로 첨가하면 물성측면에서 원하는 효과를 기대하기가 곤란하며, 15중량부를 초과하게 되면 물성치는 만족할 만하지만 경제적인 측면에서 불리한 단점이 있다.The nano-reinforcement resin having the above-described configuration is preferably added in an amount of 1 to 15 parts by weight based on 100 parts by weight of the raw material rubber. For this reason, it is difficult to expect a desired effect in terms of physical properties if added to less than 1 part by weight. If the content exceeds 15 parts by weight, the physical properties are satisfactory, but there are disadvantages in terms of economy.

상기 설명된 성분이외의 첨가제는 공지의 첨가물로 구성하여도 무방하므로 이에 관한 설명은 생략하기로 한다.Additives other than the components described above may be composed of known additives, so description thereof will be omitted.

이하 본 발명의 내용을 실시예를 통해 구체적으로 설명하도록 한다. 그러나 다음의 실시예는 본 발명을 보다 상세하게 설명하기 위한 것으로, 본 발명의 권리 범위를 이에 한정하고자 하는 것은 아니다.Hereinafter, the contents of the present invention will be described in detail through examples. However, the following examples are intended to illustrate the present invention in more detail, and are not intended to limit the scope of the invention.
