Description

고압 인젝터용 오링 고무조성물{RUBBER COMPOSITE OF O-RING FOR HIGH PRESSURE INJECTOR}Technical Field [0001] The present invention relates to a rubber composition for a high-pressure injector,

본 발명은 고압 인젝터용 오링 고무조성물에 관한 것으로서, 보다 상세하게는 가솔린 직접 분사 장치 등의 고압 인젝터에 사용되는 고압 인젝터용 오링 고무조성물에 관한 것이다. The present invention relates to an oily rubber composition for a high-pressure injector, and more particularly, to an oily rubber composition for a high-pressure injector used in a high-pressure injector such as a gasoline direct injection apparatus.

가솔린 직접 분사(Gasoline Direct Injection; GDI) 엔진은 흡기밸브의 개방시에 공기가 흡기포트로부터 연소실로 흡입되어 피스톤에 의해 압축되며, 이러한 고압공기에 대하여 엔진으로부터 연료가 직접 분사되는 방식이다.BACKGROUND ART A gasoline direct injection (GDI) engine is a system in which air is sucked from an intake port into a combustion chamber and compressed by a piston at the time of opening of an intake valve, and fuel is directly injected from the engine to such high-

자동차의 GDI 엔진 적용이 상용화됨에 따라서 고압의 가솔린 직접분사식 인젝터의 국산화가 빠르게 진행되고 있다. 이에 따라 연료의 고압화, 및 분사성능 최적화를 위하여 연료분사시 리크(leak)가 없도록 씰링 및 압력을 지지하는 오링의 고성능이 요구된다. As the application of GDI engines for automobiles is commercialized, localization of gasoline direct injection injectors with high pressure is rapidly progressing. Accordingly, in order to increase the pressure of the fuel and to optimize the injection performance, it is required to have high performance of the O-ring for supporting the sealing and the pressure so that there is no leakage during fuel injection.

특히 저온에서도 고무의 유연성을 유지하며 연료를 씰링하여야 하기 때문에 기존의 일반 고무로는 그 성능을 유지하는데 어려움이 있다. In particular, since it is necessary to seal the fuel at low temperature while maintaining the flexibility of the rubber, it is difficult to maintain the performance of the conventional rubber.

한국 특허 공개특허 10-2014-0004296Korean Patent Laid-Open No. 10-2014-0004296

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로서, GDI 엔진 등의에 사고압인젝터에 사용되는 오링으로서, 저온 성능이 향상됨과 동시에, 강성 및 신율이 우수한 고무 조성물을 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a rubber composition having improved low temperature performance and excellent rigidity and elongation as an O-ring used in a high-pressure injector such as a GDI engine.

따라서 본 발명의 고압인젝터용 오링의 고무 조성물은, 불소 고무(FKM)로 이루어진 폴리머와, 메타릴 그룹 관능기를 가지는 트리메틸 이소사이오누르산(Trimethallyl isocyanurate)가류제와, 함수실리카계 및 티타늄계를 포함하는 충진보강제를 구비한다. Therefore, the rubber composition of the o-ring for a high-pressure injector of the present invention comprises a polymer composed of a fluorine rubber (FKM), a trimethylallyl isocyanurate vulcanizing agent having a methallyl group functional group, a hydrated silica- And a filler reinforcing agent.

이 경우, 상기 충진보강제는 상기 폴리머 100 중량부에 대하여 25 내지 35 중량부를 가지고, 상기 가류제는 폴리머 100중량부에 대하여 2 내지 8 중량부를 가질 수 있다. In this case, the filler reinforcing agent is 25 to 35 parts by weight based on 100 parts by weight of the polymer, and the vulcanizing agent may have 2 to 8 parts by weight based on 100 parts by weight of the polymer.

또한, 상기 티타늄계와, 함수실리카계 간의 중량비는 7:3 내지 5:5일 수 있다. In addition, the weight ratio between the titanium system and the hydrated silica system may be 7: 3 to 5: 5.

상기 티타늄계는, 길이가 10 내지 20 μm 이고, 파이버 직경이 0.3-0.6 μm인 포타시윰 티탄네이트를 포함할 수 있다.The titanium based material may include potasitic titanate having a length of 10 to 20 占 퐉 and a fiber diameter of 0.3 to 0.6 占 퐉.

한편, 상기 티타늄계와 함수실리카계 조합이 폴리머 대비 30phr 내지 65phr일 수 있다.On the other hand, the combination of the titanium-based and hydrosilyl-based systems may be 30 phr to 65 phr of the polymer.

상기와 같은 구성을 가지는 본 발명에 의하면, 트리메틸 이소사이오누르산 가류제를 사용하여 신율물성을 향상시킴과 동시에, 함수 실리카와 티타늄계 충진 보강제를 통하여 재료의 물성이 향상된다.According to the present invention having the above-mentioned constitution, the physical properties of the material are improved through the use of the hydrated silica and the titanium-based filler reinforcing agent, while using the trimethylisocyanuric acid vulcanizing agent to improve the elongation properties.

이 경우, 포타시윰 티탄네이트를 충진제를 포함하여서, 강성을 보다 향상시킬 수 있다.In this case, it is possible to further improve the rigidity by including the filler in the titanate titanate.

도 1은 본 발명에 적용된 가류제로 트리메틸 이소사이오누르산(Trimethallyl isocyanurate)의 분자식을 도시한 도면이다. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing the molecular formula of a vulcanized trimethallyl isocyanurate applied to the present invention. FIG.

이하, 본 발명인 고압인젝터용 오링의 고무 조성물의 바람직한 일 실시예를 상세하게 설명한다.Hereinafter, a preferred embodiment of the rubber composition for an o-ring for a high-pressure injector of the present invention will be described in detail.

본 발명의 바람직한 실시예에 따른 고압인젝터용 오링의 고무 조성물은, 불소 고무(FKM)로 이루어진 폴리머와, 트리메틸 이소사이오누르산(Trimethallyl isocyanurate)를 포함하는 가류제와, 함수실리카 및 티타늄계를 포함하는 충진보강제를 포함한다. The rubber composition of the O-ring for a high-pressure injector according to a preferred embodiment of the present invention comprises a polymer composed of fluorine rubber (FKM), a vulcanizing agent containing trimethylallyl isocyanurate, a hydrated silica and a titanium- And a filler reinforcing agent.

불소 고무는 불소화도가 높은 탄화수소 고분자이다. 상기 불소고무는 우수한 내산화성, 내후성, 난연성, 내화학성, 및 내유성을 가지고 있으며, 저온성 또한 불소고무 중에서 우수한 특성을 나타낸다. Fluorocarbon rubber is a high-fluorinated hydrocarbon polymer. The fluorine rubber has excellent oxidation resistance, weather resistance, flame retardancy, chemical resistance, oil resistance, low temperature and excellent properties in fluorine rubber.

가류제는 불소고무에 화학반응을 일으켜 탄성을 갖는 고무로 변화시킨다. 즉, 소성체의 고무를 탄력성의 고무로 바꾼다. The vulcanizing agent causes a chemical reaction with the fluorine rubber to change it into an elastic rubber. That is, the rubber of the sintered body is changed into the elastic rubber.

본 발명은 가류제로서, 도 1에 도시된 바와 같이, 메탈릭 그룹 관능기를 가지는 트리메틸 이소사이오누르산(Trimethyl isocyanurate)(10)를 포함한다. 트리메탈이소사이오누르산을 적용하게 되면, 그 측쇄의 메틸 라디칼이 가교반응을 방해하게 된다. 이에 따라서 가교시간을 지연시키는 효과가 있다. 또한, 상기 메탈릭 그룹(Methallyl group)(20)은 신율을 증가시키는 기능을 한다. 상기 메틸은 혼련시에 가류밀도가 낮춰주고 안정성이 확보된다는 장점이 있다. The present invention includes, as a vulcanizing agent, trimethyl isocyanurate (10) having a metallic group functional group, as shown in Fig. When trimetalisocyanuric acid is applied, the methyl radicals in the side chain interfere with the crosslinking reaction. This has the effect of delaying the crosslinking time. In addition, the methallyl group 20 functions to increase the elongation. The methyl has an advantage that the vulcanization density is lowered and the stability is secured at the time of kneading.

통상적으로 퍼옥사이드 타입(Peroxide Type) FKM재질의 경우 일반적으로 가류제를 2~5phr 범위로 사용한다. 가류제를 상기 범위보다 높게 사용하게 되면 강성은 향상되나 신율이 저하하기 때문이다.  Normally, in the case of peroxide type FKM materials, a vulcanizing agent is used in the range of 2 to 5 phr. If the vulcanizing agent is used in a range higher than the above range, the rigidity is improved but the elongation is lowered.

본 발명에 따르면, 기존 가교제에 트리메틸 이소사이오누르산 가류제를 조합하여 신율을 향상시킨다. 이 경우, 트리메틸 이소사이오누르산은 폴리머 100 중량부 대비하여 0.5 내지 1 중량부를 가지는 것이 바람직하다. According to the present invention, an existing crosslinking agent is combined with a trimethylisocyanuric acid vulcanizing agent to improve elongation. In this case, trimethylisocyanurate is preferably used in an amount of 0.5 to 1 part by weight based on 100 parts by weight of the polymer.

이 경우, 전체 가류제는 폴리머 100중량부에 대하여 2 내지 8 중량부를 가지는 것이 바람직하다. 상기 2중량부보다 낮은 경우에는 신율 향상이 되지 않고, 상기 8중량부를 초과하는 경우에는 재료의 물성이 열화되고, 충진이 되지 않아 가류가 어렵다는 문제점이 있기 때문이다. In this case, the total vulcanizing agent is preferably 2 to 8 parts by weight based on 100 parts by weight of the polymer. If the amount is less than 2 parts by weight, the elongation can not be improved. If the amount is more than 8 parts by weight, the physical properties of the material deteriorate and the filling is not performed.

충진 보강제는 실리카 및 티타늄계를 포함한다. 통상적으로 충진 보강제로서 함수실리카 충진 보강제를 단독으로 사용하거나, 충진 보강제로서 티타늄계 충진 보강제를 단독으로 사용하였다. 그러나, 티타늄계 충진 보강제를 사용하게 되면, 강성은 우수하게 되나 신율이 열화된다는 문제점이 있다. 또한, 실리카계 충진 보강제를 사용하는 경우에는 인장강도가 열화된다는 문제점이 있다. Filler reinforcing agents include silica and titanium. As a filler reinforcing agent, a functional silica filler reinforcing agent is usually used alone or a titanium filler is used alone as a filler reinforcing agent. However, if a titanium-based filler reinforcing agent is used, there is a problem that the rigidity is excellent but the elongation is deteriorated. In addition, when a silica-based filler reinforcing agent is used, the tensile strength is deteriorated.

그러나, 본 발명에 따르면, 함수 실리카계 및 티타늄계을 조합함으로써, 재료의 강성을 향상시킴과 동시에 저온성 폴리머의 우수한 물성을 구현할 수 있다. However, according to the present invention, by combining the functional silica system and the titanium system, rigidity of the material can be improved and excellent physical properties of the low-temperature polymer can be realized.

이 경우, 상기 티타늄계와, 함수실리카계 간의 중량비는 7:3 내지 5:5인 것이 바람직하다. In this case, the weight ratio between the titanium system and the hydrated silica system is preferably 7: 3 to 5: 5.

상기 중량비가 7:3을 초과하는 경우에는, 강성은 향상되나 신율이 저하된다는 문제점이 있고, 상기 중량비가 5:5 미만인 경우에는 가류시간이 저하되고 영구 압축줄음율이 저하됨과 동시에, 유색의 오링을 만들 수 없다는 문제점이 있다. When the weight ratio is more than 7: 3, there is a problem that the rigidity is improved but the elongation is lowered. When the weight ratio is less than 5: 5, the vulcanization time is lowered and the permanent compression ratio is lowered, There is a problem that it can not be made.

본 발명에 따르면, 폴리머의 강성(100% Mo.)을 향상하면서 신율물성 또한 확보할수 있도록 티탄늄계과 함수실리카계의 최적비율 조합을 통해 물성을 구현하였다.According to the present invention, the physical properties are realized by combining the optimum ratio of titanium-based and hydrosilyl-silica systems so that the stiffness (100% Mo.) of the polymer can be improved while maintaining the elongation properties.

상기 티타늄계는, 길이가 10 내지 20 μm 이고, 파이버 직경이 0.3-0.6 μm인 포타시윰 티탄네이네 파이버를 포함하는 것이 바람직하다.Preferably, the titanium-based material includes a potassiated titanium nine fiber having a length of 10 to 20 μm and a fiber diameter of 0.3 to 0.6 μm.

한편, 티타늄계와 함수실리카계의 조합이 폴리머 대비, 30phr 미만으로 적용되는 경우에는 강성이 저하된다는 문제점이 있고, 그 조합이 65phr를 초과하는 경우에는 신율저하 및 기포 또는 표면불량 등의 가류부적합 현상이 나타난다. On the other hand, when the combination of the titanium system and the hydrated silica system is applied at less than 30 phr, there is a problem that the rigidity is lowered. When the combination exceeds 65 phr, the elongation decrease and the vulcanization failure such as bubble or surface defects .

따라서, 티타늄계와 함수실리카계 조합이 폴리머 대비 30phr 내지 65phr인 것이 바람직하다. Therefore, it is preferable that the combination of the titanium-based and hydrated silica-based materials is 30 phr to 65 phr with respect to the polymer.

이하에서는, 상기와 같은 본 발명의 실시예에 따른 오링의 고무 조성물(이하 편의상 "실시예"라고 칭함.)을 종래의 FKM 오링의 고무조성물(이하, 편의상 "비교예"라고 칭함.)간의 성질을 각종 테스트하여 서로 비교함으로써, 상기 효과를 더욱 명확하게 설명한다.Hereinafter, the rubber composition of the O-ring according to the embodiment of the present invention (hereinafter referred to as "the embodiment " for convenience) will be referred to as the rubber composition of the conventional FKM O-ring And the above-mentioned effects will be more clearly explained.
