Abstract
Description
본 발명은 빙설길 또는 빙판길에서 타이어의 제동력을 향상시키기 위하여 사용되는 고무 스파이크핀(RUBBER SPIKE PIN)의 취약부에서 발생하는 균열 및 파열 등을 방지할 뿐 아니라 제동효과가 우수한 폴리올레핀 레진을 기존 고무와 혼용하여서 만든 고무 스파이크 핀에 관한 것이다.The present invention not only prevents cracking and rupture generated at the weak part of the rubber spike pin (RUBBER SPIKE PIN), which is used to improve the braking force of a tire on an ice road or an ice road, but also provides an excellent braking effect with a polyolefin resin. A rubber spike pin made of mixed materials.
종래에는 빙설길 또는 빙판길에서 타이어의 미끄러짐 현상을 방지하기 위하여 초경합금 스파이크 핀을 사용하였다. 이것은 제동 효과가 우수한 반면 소음, 도로손상 및 분진 등의 문제점을 가지고 있어 이를 규제하는 법안이 나왔다. 따라서 이에 대한 대응으로 초경합금 대신 고무 스파이크 핀이 개발되었다. 이것은 유리전이온도(glass transition temperature)가 -5∼10 범위인 고무 배합물을 성형함으로써 이루어진 것으로서, 빙점하에서 경화되어 딱딱해지기 때문에 이 딱딱한 부분이 빙면에 접촉하였을 때 마찰력 및 빙면 표면 적응력으로 인해 제동효과를 유발시킨 원리를 이용한 것이다. 이러한 고무 스파이크 핀에 의해 소음, 도로손상, 분진공해 등의 문제점은 어느 정도 해결이 가능하였으나 지지부와 핀봉 사이의 경계면 부근에서 응력이 집중되어 균열 및 파열 등이 발생되기 때문에 문제점으로 지적되어왔다.Conventionally, cemented carbide spike pins have been used to prevent tire slippage on ice or ice. While this has excellent braking effect, it has a problem such as noise, road damage and dust. Accordingly, rubber spike pins have been developed in response to cemented carbides. This is achieved by molding a rubber compound with a glass transition temperature in the range of -5 to 10, which hardens and hardens under the freezing point so that the braking effect is due to friction and surface adaptability when the hard part contacts the ice. Using the principle that caused the. The problem of noise, road damage, dust pollution, etc. can be solved to some extent by the rubber spike pins, but it has been pointed out as a problem because stress is concentrated near the interface between the support and the pin rod, causing cracking and rupture.
본 발명은 기존과 고무 스파이크 핀을 개량하여 상기와 같은 문제점을 해결하기 위한 것으로, 원료고무로서 고무-플라스틱 혼용의 가류물을 적용하여 가류물의 물성개선 및 공정성뿐만 아니라 기존의 고무 스파이크 핀의 가장 큰 문제점인 지지부와 핀봉 사이의 경계면 부근에서 흔히 발생하는 균열 및 파열현상을 현저히 개선시킬 수 있었다.The present invention is to solve the above problems by improving the conventional rubber spike pins, by applying a rubber-plastic mixed vulcanizate as a raw material rubber, as well as the physical properties and processability of the vulcanizate, the largest of the conventional rubber spike pins The problem of cracking and tearing, which occurs frequently near the interface between the support and the pin rod, can be remarkably improved.
이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명의 고무 스파이크 핀은, 유리전이온도 -5∼10℃범위의 고무조성물을 성형 가황함으로써 이루어지는 통상의 고무 스파이크 핀에 있어서, 상기 고무조성물의 원료고무 100중량부에 대하여 폴리에틸렌 또는 폴리프로필렌으로부터 선택되는 폴리올레핀 레진 10∼80중량부가 첨가된 것을 특징으로 한다.The rubber spike pin of the present invention is a conventional rubber spike pin formed by vulcanizing a rubber composition having a glass transition temperature of -5 to 10 ° C, and is selected from polyethylene or polypropylene with respect to 100 parts by weight of the raw material rubber of the rubber composition. It is characterized in that 10 to 80 parts by weight of the polyolefin resin is added.
여기에서 상기 원료고무는 현재 고무 스파이크 핀의 원료 고무로 많이 사용하는 NBR고무와 혹은 NBR/SBR 혼용 고무를 비롯한 각종 합성고무 및 천연고무를 사용할 수 있고 특별히 한정되는 것은 아니며, 이 원료고무를 포함하는 고무조성물이 상기 -5∼10℃범위의 유리전이온도를 가지고 있어 상온에서는 연화되고 빙점이하에서는 경화되어 스파이크 핀으로서 작용할 수 있으면 된다.Here, the raw material rubber may use various synthetic rubber and natural rubber, including NBR rubber and NBR / SBR mixed rubber, which are currently used as raw rubber of rubber spike pins, and are not particularly limited. The rubber composition has a glass transition temperature in the range of −5 to 10 ° C. so that it softens at room temperature and hardens below freezing point so that it can act as a spike pin.
한편, 상기 폴리올레핀 레진은 폴리에틸렌 또는 폴리프로필렌 레진 중에서 선택되는 것이다. 본 발명에 있어서는 원료고무 100 중량부에 대해서, 이 폴리올레핀 레진을 10∼80중량부를 사용하게 되는데, 이 범위보다 적은 량을 사용하면 충분한 내구력 향상효과를 달성할 수 없으며, 이 범위보다 많게 되면 고무 스파이크 핀으로서 필요한 조성물의 유리온도범위를 달성하기 위해서는 곤란하게 되고 다량의 가소제를 사용하여야 하기 때문에 바람직하지 않다.On the other hand, the polyolefin resin is selected from polyethylene or polypropylene resin. In the present invention, 10 to 80 parts by weight of the polyolefin resin is used with respect to 100 parts by weight of the raw material rubber. When the amount is less than this range, sufficient durability improvement effect cannot be achieved. It is not preferable because it is difficult to achieve the glass temperature range of the required composition as a pin and a large amount of plasticizer must be used.
다른 한편, 폴리올레핀 레진은 그 성질상 원료고무는 혼용특성이 좋지 않은 편인데, 이를 개선하기 위해서는, 0.1∼0.5중량부의 SnCl2존재하에서 상기 폴리올레핀 레진 100중량부당 1∼5중량부의 디메틸을 페닐릭 컴파운드와 같은 페놀릭 가교제로 처리함으로써 얻어지는 페놀기에 의해 치환된 레진을 사용하는 것이 바람직하다.On the other hand, polyolefin resins have poor mixing properties due to their properties. To improve this, 1 to 5 parts by weight of dimethyl per 100 parts by weight of polyolefin resin is phenylic compound in the presence of 0.1 to 0.5 parts by weight of SnCl 2. It is preferable to use the resin substituted by the phenol group obtained by processing with such phenolic crosslinking agents.
본 발명의 고무 스파이크 핀을 제조하기 위한 고무조성물에는, 상기 원료고무 및 폴리올레핀 레진 이외에도, 예컨대 충진제, 가류제 및 가류촉진제 및 가소제 등의 종래 고무 스파이크 핀용의 의 제조에 사용되던 고무조성물에 첨가되는 각종 첨가제가 포함된다. 다만, 본 발명에서는 원하는 범위의 유리온도를 얻기 위해서는 폴리올레핀 레진을 첨가하지 않는 경우에 비해 다량의 가소제를 첨가할 필요가 있다.The rubber composition for producing the rubber spike pin of the present invention, in addition to the raw material rubber and polyolefin resin, various kinds of rubber compositions used in the manufacture of conventional rubber spike pins, such as fillers, vulcanizing agents and vulcanization accelerators and plasticizers, for example Additives are included. However, in the present invention, in order to obtain a glass temperature in a desired range, it is necessary to add a large amount of plasticizer as compared with the case where no polyolefin resin is added.
