Abstract
Description
본 발명은 기유; 몰리브덴 화합물; 카본블랙; 및 분산제를 포함하는 엔진오일용 조성물에 관한 것으로, 보다 상세하게는 내마모성이 우수하고, 엔진 성능의 복원이 가능하며, 엔진의 효율과 수명을 연장할 수 있는 엔진오일용 조성물에 관한 것이다. The present invention relates to a base oil; Molybdenum compounds; Carbon black; And a dispersant. More particularly, the present invention relates to a composition for engine oil, which is excellent in abrasion resistance, capable of restoring engine performance, and capable of extending engine efficiency and service life.
엔진오일은 금속과 금속 사이의 마찰을 감소시키고, 내부에서 발생하는 뜨거운 열을 외부로 배출하여 엔진부품의 열을 식혀주며, 해로운 찌꺼기를 없애 내부 부품을 깨끗하게 유지함으로써 연비개선에 도움을 주는 기능을 수행한다. Engine oil reduces the friction between the metal and the metal, discharges hot heat from the outside to cool the engine components, and eliminates harmful debris to keep internal components clean, helping to improve fuel economy. .
즉, 엔진오일은 내연기관이 구비되는 자동차, 선박, 비행기 등에서 윤활작용, 냉각작용, 부식방지작용, 세정작용 등의 기능을 수행함으로써, 내연기관의 저연비화 등의 성능 발휘에 중요한 역할을 한다.That is, engine oil plays an important role in performance such as low fuel consumption of an internal combustion engine by performing functions such as lubricating action, cooling action, corrosion preventing action and cleaning action in an automobile, a ship and an airplane equipped with an internal combustion engine.
그런데 엔진오일은 오일 중에 오염물질이 퇴적되고 오일에서 발생되는 화학적 변화, 특히 산화생성물의 생성으로 인하여 그 성능이 쉽게 저하될 수 있다. Engine oil, however, can easily degrade its performance due to the accumulation of contaminants in the oil and the chemical changes that occur in the oil, especially the formation of oxidation products.
엔진 중에 오염물질이 퇴적되는 주된 이유는, 엔진의 작동 중에 오일이 적절히 공급되지 못하여 금속과 금속이 부딪침에 따라 마모가 발생되기 때문이다. The main reason for the contaminants to accumulate in the engine is that oil is not properly supplied during operation of the engine and wear occurs as the metal and metal collide.
특히 엔진의 시동 시에 이러한 마모가 많이 발생하게 되는데, 이는 엔진오일이 유동성 있는 물질로 이루어져 있어, 엔진의 시동 시에 원활히 공급되지 못하기 때문이다. 또한 엔진이 고열상태인 경우에도 오일이 원활한 유막을 형성하지 못하여 마모가 잘 이루어진다.Particularly, such abrasion occurs at the start of the engine because the engine oil is made of a fluid material and can not be supplied smoothly when the engine is started. In addition, even when the engine is in a high temperature state, the oil does not form a smooth oil film and wears well.
또한 상기 마모가 발생된 금속은 오일 중에서 다른 화학첨가제와 반응을 일으켜 쉽게 산화되거나 또는 이차적인 산화생성물을 형성하게 되고 이는 엔진에 악영향을 끼치게 된다.In addition, the abrasive metal reacts with other chemical additives in the oil to easily oxidize or form a secondary oxidation product, which adversely affects the engine.
따라서 이러한 엔진오일의 성능을 향상시키기 위하여, 엔진오일 첨가제 또는 이를 포함하는 엔진오일 조성물에 대한 연구개발이 활발히 이루어지고 있다.Therefore, in order to improve the performance of the engine oil, researches and developments of an engine oil additive or an engine oil composition containing the engine oil additive are actively conducted.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 내마모성이 우수하고, 엔진 성능의 복원이 가능하며, 엔진의 효율과 수명을 연장할 수 있는 엔진오일용 조성물을 제공하는 것을 목적으로 한다.

(2) 내마모성 (2) Abrasion resistance
Top 볼이라 불리는 4번째의 강철 볼이 3개의 볼 위에 올려지고, 특정 하중의 압력을 가하여 Top 볼을 회전시켰다.Top A fourth steel ball, called a ball, was placed on top of the three balls, applying a specific load of pressure to rotate the top ball.
회전을 중지한 후, 3개의 아래 볼에서 발생한 마모흔의 평균크기를 비교하여 내마모성을 측정하였다. After stopping the rotation, the abrasion resistance was measured by comparing the average size of the abrasion marks generated in the three lower balls.
(3) 동점도(3) Kinematic viscosity
ASTM D 445에 의거하여 측정하였다. And measured according to ASTM D 445.
(mm3/s)Kinematic viscosity (100 ° C)
