Description

저온에서 윤활 성능이 우수한 그리이스 조성물{Grease composition having excellent lubrication performance at low temperature}[0001] The present invention relates to a grease composition having excellent lubrication performance at low temperatures,

본 발명은 저온에서 윤활 성능이 우수한 그리이스 조성물에 관한 것이다.
The present invention relates to a grease composition excellent in lubrication performance at a low temperature.

일반적으로 그리이스는 부품간 원활한 윤활작용을 위해 사용되는데, 보다 효율적인 윤활 작용을 위해 점성이 낮은 저점도 그리이스를 사용할 경우 마찰 운동시 부품간 소음 문제가 발생하고 그리이스의 내열성을 확보하는데 어려움이 있다. 반면 점성이 높은 고점성 그리이스를 사용할 경우 저온에서 윤활특성이 저감되는 문제점이 있다.Generally, grease is used for smooth lubrication between parts. When a low-viscosity grease with low viscosity is used for more efficient lubrication, there is a problem of noise between parts during friction movement and it is difficult to secure heat resistance of grease. On the other hand, when a high viscosity high-viscosity grease is used, there is a problem that the lubrication characteristics are reduced at low temperatures.

종래 이러한 그리이스 조성물에 관해 한국등록특허 제969797호에는 고점도 폴리알파올레핀과 저점도 폴리알파올레핀이 혼합된 합성기유와 알루미늄 이소-프로폭시드, 벤조인산, 스테아린산 및 올레인산으로 이루어지는 복합비누 증주제 및 첨가제로 이루어진 그리이스 조성물에 관해 제안되어 있으나, 부품조작 원활감을 위한 그리이스의 저점성 확보에 단점이 있다.Conventionally, Korean Patent No. 969797 discloses a grease composition comprising a synthetic base oil in which a high viscosity polyalphaolefin and a low viscosity polyalphaolefin are mixed together, and a composite soap thickener composed of aluminum isopropoxide, benzoic acid, stearic acid and oleic acid, There is a disadvantage in securing the low viscosity of the grease for smooth operation of the parts.

또한 한국등록특허 제521599호에는 폴리알파올레핀과 광유가 혼합된 합성기유, 우레아계 증주제, 폴리부텐 및 에틸렌 프로필린 폴리머가 함유된 그리이스 조성물에 관해 제안되어 있으나, 광유로 인하여 저온 윤활성 측면에서 단점이 있다.Korean Patent No. 521599 also discloses a grease composition containing a synthetic base oil, a urea thickener, a polybutene, and an ethylene propylene polymer mixed with a polyalphaolefin and a mineral oil. However, since the mineral oil causes a drawback in terms of low temperature lubricity have.

이러한 문제점을 해결하기 위해 저온에서 유동성이 우수한 고점도 실리콘 기유를 사용하지만, 고가의 가격 및 전장부품(전기접점부) 통전 불량 문제를 일으킬 가능성이 높아 사용상의 제약이 따른다. In order to solve these problems, a highly viscous silicon base oil having excellent fluidity at a low temperature is used, but there is a high possibility of causing a problem of high cost and defective energization of electric parts (electrical contacts).

따라서 이를 해결하기 위한 저온에서 윤활성능이 우수한 그리이스에 대한 연구가 필요한 실정이다.
Therefore, it is necessary to study the grease which has excellent lubrication performance at low temperature to solve this problem.

본 발명의 목적은 저점도 기유에 고분자가 혼합된 그리이스 조성물을 제공하는데 있다.It is an object of the present invention to provide a grease composition in which a polymer is mixed with a low viscosity base oil.

이하에서는 본 발명을 하나의 구현예로써 더욱 자세하게 설명한다.Hereinafter, the present invention will be described in more detail as an embodiment.

본 발명은 그리이스 조성물에 있어서,The present invention relates to a grease composition,

기유 70 ~ 85 중량%;70 to 85% by weight of base oil;

폴리이소부틸렌, 에틸렌 올리고머 또는 이들의 혼합물로 이루어진 고분자 7 ~ 18 중량%; 및7 to 18% by weight of a polymer composed of polyisobutylene, ethylene oligomer or a mixture thereof; And

본 발명의 바람직한 구현예에 따르면, 상기 기유는 100℃에서 점도가 4 ~ 8 cSt로 저점도인 폴리알파올레핀(PAO: Poly Alpha Oleffin) 합성기유를 사용할 수 있다. 가장 바람직하기로는 100℃에서 점도가 6 cSt인 것을 사용하는 것이 좋다. 이는 순수 고점도의 폴리알파올레핀이 존재하지만 상기 고점도 폴리알파올레핀의 합성기유를 사용할 경우 저온에서 유동성이 떨어지는 문제가 발생하므로 저온에서 윤활성능이 우수한 점성이 낮은 저점도 폴리알파올레핀을 사용하는 것이 바람직하다.According to a preferred embodiment of the present invention, the base oil may use a polyolefin olefin (PAO) synthetic base oil having a viscosity of 4 to 8 cSt and a low viscosity at 100 ° C. Most preferably, it has a viscosity of 6 cSt at 100 캜. However, when the synthetic base oil of the high viscosity polyalphaolefin is used, there arises a problem of low fluidity at a low temperature, so it is preferable to use a low viscosity polyalphaolefin having a low viscosity and low viscosity at low temperature .

본 발명의 바람직한 구현예에 따르면, 상기 고분자는 폴리이소부틸렌(PIB: Polyisobutylene), 에틸렌 올리고머(Ethylene Oligomer) 또는 이들의 혼합물을 점도가 낮은 저점도 폴리알파올레핀 합성기유에 혼합하면 합성기유 내에 고분자의 이동으로 인해 점도가 높아지는 특성이 있다. 이때 상기 고분자의 함량은 7 ~ 8 중량%를 사용하는 것이 바람직한데 함량이 7 중량% 보다 적으면 기유 점도가 낮아져 그리이스의 이유도 측면에서 불리할 수 있으며, 18 중량% 보다 많으면 점도의 증가로 인해 저온 특성이 불리해지는 단점이 있다.According to a preferred embodiment of the present invention, the polymer may be prepared by mixing a polyisobutylene (PIB), an ethylene oligomer or a mixture thereof with a low viscosity polyalphaolefin synthetic base oil having a low viscosity, There is a characteristic that the viscosity increases due to the movement of the catalyst. When the content is less than 7% by weight, the viscosity of the base oil is lowered, which is disadvantageous in terms of the reasons for the grease. When the content is more than 18% by weight, the viscosity of the polymer is increased There is a disadvantage that the low-temperature characteristics are disadvantageous.

본 발명의 바람직한 구현예에 따르면, 상기 복합금속비누계 증주제에서 금속은 리튬, 나트륨, 칼슘, 바륨 및 알루미늄으로 이루어진 군에서 선택된 1종 이상인 것을 사용하는 것이 좋으며, 가장 바람직하기로는 복합리튬비누를 사용하는 것이 좋다. 일반적으로 그리이스 증주제는 복합금속비누계, 우레아계(UREA), 금속비누계 증주제 등을 사용할 수 있는데, 저점성화에 따른 내열성을 확보하기 위해서는 복합금속비누계 증주제를 사용하는 것이 바람직하다. 이는 우레아계(UREA) 및 금속비누계 증주제를 사용할 경우 이유도가 높아지는데, 이유도가 높아지면 기유의 누유가 발생하여 내열성이 떨어지는 문제가 발생한다. 이때 상기 금속비누계 증주제의 함량은 4 ~ 13 중량%를 사용하는 것이 바람직하다. 이때 함량이 4 중량% 보다 낮으면 그리이스 제조가 어려운 단점이 있으며, 13 중량% 보다 높으면 그리이스 점성이 높아져 그리이스를 사용하는 부품의 조작 원활감을 저하할 수 있다. 더욱 바람직하기로는 4.5 ~ 12.1 중량%를 사용하는 것이 좋다. According to a preferred embodiment of the present invention, the metal in the composite metal soap thickener may be at least one selected from the group consisting of lithium, sodium, calcium, barium and aluminum, and most preferably, a composite lithium soap is used It is good to do. Generally, the grease thickener may be a composite metal soap system, a urea system (UREA), a metal soap-based thickener, etc. In order to secure heat resistance due to low viscosity, it is preferable to use a composite metal soap thickener. This is because the use of urea-based (UREA) and metal soap-based thickener increases the reason, and when the reason is high, the base oil leaks and the heat resistance becomes poor. At this time, the content of the metal soap thickener is preferably 4 to 13 wt%. If the content is less than 4% by weight, the production of the grease is difficult. If the content is higher than 13% by weight, the viscosity of the grease increases, which may deteriorate the smooth feeling of operation of the parts using the grease. It is more preferable to use 4.5 to 12.1 wt%.

한편 본 발명은 상기 조성물을 포함하는 자동변속기 변속레버용 그리이스를 특징으로 한다.The present invention also provides a grease for an automatic transmission shift lever comprising the composition.

따라서 본 발명에 따른 그리이스 조성물은 저점도 폴리알파올레핀에 폴리이소부틸렌, 에틸렌 올리고머 등의 고분자를 혼합함으로써 저온에서 윤활성능이 우수하고 내열성을 향상시킬 수 있으며 이를 이용할 경우 부품간의 진동 및 소음을 저감할 수 있다.
Therefore, the grease composition according to the present invention can improve the lubrication performance at low temperatures and improve the heat resistance by mixing polyisobutylene, ethylene oligomer and other polymers with low viscosity polyalphaolefin, and it can reduce vibration and noise among parts when used can do.

이하, 본 발명을 실시예에 의거하여 더욱 상세히 설명하겠는 바, 본 발명이 다음 실시예에 의해 한정되는 것은 아니다.

상기 표 2에 나타낸 바와 같이, 고점도 폴리알파올레핀을 함유한 비교예 3에 비해 저점도 폴리알파올레핀을 함유한 상기 실시예 1 ~ 5의 경우 25℃ 및 -40℃의 저온에서 점성이 낮은 것을 확인할 수 있다. 고점도 폴리알파올레핀과 저점도 폴리알파올레핀을 함유한 실시예에서 내열성을 확인하는 이유도 측면에서도 부품(변속레버)에 적용시 문제없는 수준으로 우수함을 확인할 수 있다. 또한 고분자의 함량이 적은 비교예 1은 저온에서 낮은 점성을 나타내지만 이유도가 높아 내열성이 불리하고, 고분자의 함량이 많은 비교예 2는 이유도는 낮게 확인이 되나 저온에서 높은 점성을 나타내어 저온특성이 불리함을 확인할 수 있다. As shown in Table 2, in Examples 1 to 5 containing a low viscosity polyalphaolefin, viscosity was low at a low temperature of 25 ° C and -40 ° C compared with Comparative Example 3 containing a high viscosity polyalphaolefin . It can be confirmed that the embodiment in which the high viscosity polyalphaolefin and the low viscosity polyalphaolefin are contained is superior to the component (shift lever) in terms of the reason for confirming the heat resistance. Comparative Example 1, which has a low polymer content, exhibits a low viscosity at low temperature but has a high degree of heat resistance and has a disadvantage in heat resistance. Comparative Example 2, which has a high polymer content, It can be confirmed that this is disadvantageous.

한편 고분자를 첨가하지 않은 비교예 4의 경우 점성이 낮아서 조작감 측면에서 유리할 수 있지만 이유도가 높게 나오는 것을 확인할 수 있다. 또한 복합리튬비누 증주제 대신 리튬비누 또는 우레아 증주제를 사용한 비교예 5, 6의 경우 25℃ 및 -40℃에서 복합리튬비누 증주제를 사용한 실시예와 비슷한 점성 수준을 유지하였으나 이유도가 상기 실시예 1 ~ 5에 비해 이유도가 4.5 중량% 이상으로 높아 내열성이 떨어지는 것을 알 수 있다.On the other hand, in Comparative Example 4 in which the polymer is not added, the viscosity is low, which is advantageous from the operational viewpoint, but it can be confirmed that the reason is high. In Comparative Examples 5 and 6 using a lithium soap or a urea thickener instead of the complex lithium soap thickener, the viscosity levels remained similar to those of the examples using the composite lithium soap thickener at 25 ° C and -40 ° C, 5, the heat resistance is inferior due to the reason that the moisture resistance is as high as 4.5% by weight or more.

따라서 본 발명에 따른 그리이스 조성물은 저점도 폴리알파올레핀에 폴리이소부틸렌, 에틸렌 올리고머 등의 고분자를 혼합함으로써 저온에서 윤활성능이 우수하고 내열성을 향상시킬 수 있으며 이를 이용할 경우 부품간의 진동 및 소음을 저감할 수 있다.
Therefore, the grease composition according to the present invention can improve the lubrication performance at low temperatures and improve the heat resistance by mixing polyisobutylene, ethylene oligomer and other polymers with low viscosity polyalphaolefin, and it can reduce vibration and noise among parts when used can do.
