Description

리튬 복합비누 투명 그리스 조성물{lithium complex soap clear grease composition}[0001] The present invention relates to a lithium complex soap clear grease composition,

본 발명은 리튬 복합비누 투명 그리스 제조방법에 관한 것으로서 더욱 상세하게는 나프텐 윤활기유(eil.N 100~200)에 리튬 복합 증주제를 사용하고 각종 첨가제를 첨가하여 가공 균질화 시킴으로써 내열성, 즉 열 안정 성능이 우수하고 내하중성이 뛰어나며 윤활수명이 긴 새로운 조성의 리튬 복합비누 투명 그리스의 제조에 관한 것이다.More particularly, the present invention relates to a process for producing a lithium composite soap clear grease, and more particularly, to a process for producing a lithium composite soap clear grease by using a lithium compound thickener for naphthenic lubricating oil (eil.N 100-200) To a new composition of a lithium composite soap clear grease which is excellent in durability and excellent in lubrication life.

일반적인 리튬 복합비누 투명 그리스는 기유가 광유이고, 증주제가 세 가지 요소 즉 지방산(Fatty acid), 붕산(Boric acid), 및 리튬(Lithium)으로 구성되어 있다.A typical lithium composite soap clear grease is a mineral oil, and the thickener consists of three components: Fatty acid, Boric acid, and Lithium.

상기와 같은 종래의 일반적인 리튬 복합비누 투명 그리스의 증주제 반응은 도 1에서와 같이 2단계에 걸쳐 제조되고 있으며, 그 예를 살펴보면 아래와 같다.The conventional thickener reaction of lithium complex soap clear grease as described above is produced in two steps as shown in FIG. 1, and examples thereof are as follows.

종래의 리튬 복합비누 투명 그리스는 제조공정 중 쉽게 물러지고 온도와 하중 등의 사용조건이 혹해지면 쉽게 이유, 유출되어 열 안정성과 전단안전성 및 내하중성능이 떨어지는 문제점을 가진다.Conventional lithium composite soap clear grease easily disintegrates during the manufacturing process, and when used conditions such as temperature and load are worsened, there is a problem that heat stability, shear safety, and load-bearing performance deteriorate due to easy reason and leakage.

일례를 들어 제철산업의 압연, 냉간, 선제공정에서 고온부위의 윤활은 고온부위 베어링 온도를 냉각시키면서 높은 하중에 베어링의 파손이 없이 장기적인 성능을 발휘하여야 한다.For example, in the rolling, cold rolling, and preheating processes of the steel industry, the lubrication of the high temperature part should exhibit long-term performance without damaging the bearings at high load while cooling the high temperature part bearing temperature.

이러한 용도로 사용되는 리튬 복합비누 투명 그리스가 내열성과 내하중성이 떨어지는 저급품일 경우에는 베어링 등의 윤활성이 저하되고 내구성에 문제를 야기시켜 각종산업분야의 생산성의 차질은 물론, 안전사고의 위험성이 높아지는 등 많은 문제점이 발생하게 된다.In the case of a low-fat, low-heat-resistant and low-load-resistant lithium composite soap clear grease used for such purposes, the lubricity of the bearing and the like is lowered, causing durability problems, And so on.

이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명된 것으로서 리튬 복합비누 투명 그리스의 제조공정을 개선하고 윤활기유의 성능을 향상시키고 증주제와 첨가제의 성능을 향상시켜 윤활부위 사용시, 적점을 높이고 이유도를 적게 하여 열 안정성이 우수하도록 하며 내하중성을 향상시켜 장기 윤활이 가능하도록 하는데 목적이 있다.Accordingly, it is an object of the present invention to overcome the above-mentioned problems, and it is an object of the present invention to improve the manufacturing process of the lithium composite soap clear grease, improve the performance of the lubricant oil, improve the performance of the thickener and the additive, To improve the thermal stability and to improve the load resistance to enable long-term lubrication.

본 발명의 구성은 다음과 같다.The structure of the present invention is as follows.

윤활기유와 증주제로 이루어지는 리튬 복합비누 그리스를 제조함에 있어서; In producing a lithium composite soap grease comprising a lubricating oil and a thickener,

상기 리튬 복합비누 그리스는 반응기에 전체 사용되는 윤활기유의 40∼50%와 고급 지방산 리튬 비누 증주제 4∼15%를 가하여 180℃까지 올려 휘저음 하여 용해 시키고;The lithium composite soap grease is added to the reactor in an amount of 40 to 50% of the total amount of the lubricant oil and 4 to 15% of the high fatty acid lithium soap thickener, heated to 180 DEG C and stirred to dissolve;

용해 후 윤활기유 20∼30%를 가하여 90℃로 냉각시키고 붕산과 물을 투입하여 용해한 후, 200℃로 가열시켜 반응시키고 나머지 나프텐 윤활기유로 냉각하고, 첨가제를 투입하여 휘저음 시킨 후 3롤밀 가공 후 탈포시켜 제조하고;After the dissolution, 20 to 30% of the lubricating oil was added, the mixture was cooled to 90 DEG C, boric acid and water were added to dissolve the mixture, and the mixture was heated to 200 DEG C for reaction. The remaining naphthene lubricant channel was cooled. Followed by defoaming;

상기 리튬 복합비누 투명 그리스에는 성능이 향상된 나프텐 윤활기유에 증주제로서 고급지방산으로 검화된 리튬 복합 증주제가 균질화 되어있는 것을 특징으로 한다.The lithium composite soap clear grease is characterized in that a lithium compound thickener, which is a naphthene lubricant oil having improved performance, is thickened as a higher fatty acid as a thickener, is homogenized.

이하 첨부되는 도면과 관련하여 상기 목적을 달성하기 위한 본 발명의 바람직한 제조의 실시 예와 작용에 대하여 설명하면 다음과 같다. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 기술이 적용된 리튬 복합비누 투명 그리스의 화학반응도, 도 3은 종래기술과 본 발명에 의하여 제조된 리튬 복합비누 그리스의 성능시험 결과표도로서 함께 설명한다.FIG. 2 is a chemical reaction diagram of a lithium composite soap clear grease to which the technique of the present invention is applied, and FIG. 3 is a graph illustrating a performance test result of the lithium composite soap grease manufactured according to the prior art and the present invention.

본 발명에서는 나프텐 윤활기유와 증주제로 이루어지는 리튬 복합비누 투명 그리스를 제조함에 있어, 나프텐 윤활기유를 성능이 우수한 것을 사용하고 고급지방산으로 검화된 리튬 비누로 이루어진 복합 증주제를 사용하여 반응시키고 가공공정을 거쳐 균질화 시키는 것을 특징으로 한다.In the present invention, in producing a lithium composite soap clear grease consisting of a naphthene lubricating oil and a thickener, a naphthene lubricating oil is reacted using a compound thickener made of a lithium soap moistened with a higher fatty acid, And then homogenized.

본 발명에서 사용되는 나프텐 윤활기유의 성분은 석유로부터 정제한 탄화수소유와 합성윤활유를 포함한다.The naphthenic lubricating oil components used in the present invention include hydrocarbon oils purified from petroleum and synthetic lubricating oils.

상기 합성윤활유로는 에틸렌, 프로필렌 계열의 탄화수소계유를 사용하고, 증주제로는 고급지방산으로 검화된 복합 증주제를 사용하고, 스테아린산의 혼합물을 검화시킨 리튬 비누 증주제를 복합 증주제로 사용한다.As the synthetic lubricating oil, ethylene-propylene-based hydrocarbon-based oil is used, and as the thickener, a complex thickener which is saponified with a higher fatty acid is used and a lithium soap thickener obtained by saponifying a mixture of stearic acid is used as a compound thickener.

본 발명의 리튬 복합비누 투명 그리스의 증주제의 함량은 전체 그리스의 4∼15%로 조절하는데, 함량이 너무 적으면 산화안정성이 좋지않게 되고 적점이 떨어지게 되며 전단 안정성이 좋지않게 된다.The content of the thickener of the lithium composite soap clear grease of the present invention is adjusted to 4 to 15% of the total grease. If the content is too low, the oxidation stability becomes poor, the red dot becomes poor, and the shear stability becomes poor.

그리고 함량이 너무 많으면 주도 등급이 높아 급지성능이 좋지않고 찌꺼기가 많아져 윤활성이 좋지않기 때문에 바람직하지 못하다.If the content is too high, the feedability is not good and the residue becomes large due to a high lead level, which is not preferable because the lubricity is not good.

상기와 같은 본 발명의 리튬 복합비누 투명 그리스의 제조과정을 바람직한 실시 예를 통하여 살펴보면 아래와 같다.The process for producing the lithium composite soap clear grease of the present invention as described above will be described below with reference to the preferred embodiments.

[실시 예][Example]

반응기에 성능이 향상된 윤활기유의 40∼50%와 고급 지방산 리튬 증주제 4∼15%를 가하고 온도를 160℃까지 올려 휘저음 하여 용해한다.Add 40 ~ 50% of lubricant oil with improved performance and 4 ~ 15% of high fatty acid lithium thickener to the reactor, raise the temperature to 160 ℃ and dissolve by dissolving.

완전히 용해된 후 윤활기유 20∼30%를 투입하여 90℃로 냉각시켜, 붕산을 천천히 투입하고 용해한다.After completely dissolved, 20-30% of lubricating oil is added and cooled to 90 ° C. Boric acid is slowly added and dissolved.

물을 넣고 휘저음 시킨 후 200℃로 가열시킨 후 나머지 윤활기유로 냉각시켜 첨가제를 투입 후 여과 및 3롤 밀 가공 후 탈포시킨다.After adding water and stirring, the mixture is heated to 200 ° C, and the remaining lubricant is cooled by the addition of additives, followed by filtration and 3-roll milling, followed by defoaming.

상기와 같은 본 발명은 도 3에 도시된 종래기술과의 성능비교시험도표에서와 같이 제조공정이 기존의 리튬 복합비누 투명 그리스의 제조공정보다 단축되어 품질향상에 기여할 수 있고, 제품의 품질이 우수하여 높은 적점을 가지고 이유도가 적어 쉽게 흘러내리지 않고 전단력과 내하중성이 우수한 장점을 가진다.As shown in the performance comparison chart of FIG. 3, the present invention can reduce the manufacturing process of the conventional lithium composite soap clear grease, thereby contributing to quality improvement. And it has the advantage of excellent shear force and load-bearing property without flowing easily because of its low viscosity.

상기와 같은 본 발명의 리튬 복합비누 투명 그리스는 상기 특성과 장점에 의하여 제철산업과 같이 고온 고하중 윤활부위의 가혹한 조건에 사용할 경우에도 충분히 견딜 수 있어 장기 윤활히 가능하여지는 것이다.The above-mentioned lithium composite soap clear grease of the present invention can withstand the harsh conditions of the high temperature and high load lubrication area as in the steel industry due to the above characteristics and merits, thereby being able to withstand long periods of time.

이상과 같은 본 발명은 리튬 복합비누 그리스의 제조공정을 개선하고 윤활기유의 성능을 향상시키고 증주제와 첨가제의 성능을 향상시켜 적점을 높이고 이유도를 적게 하여 열 안정성이 우수하도록 하며 내하중성을 향상시켜 장기 윤활히 가능하도록 할 수 있는 등의 얻을 수 있는 효과가 있는 것이다.The present invention improves the manufacturing process of lithium composite soap grease, improves the performance of the lubricant oil, improves the performance of the thickener and the additive, increases the redness point, reduces the degree of the reason and improves the thermal stability, It is possible to make it possible to perform lubrication and the like.
