Abstract

유압작동유 중 수글리콜계는 난연성이 우수한 특징이 있으나 사용원료가 고가인 문제가 있었다. 본 발명은 중점제로 에틸렌글리콜을 개시원료 하여 에틸렌옥사이드와 프로필렌옥사이드를 랜덤부가 중합한 PAG(폴리 알킬렌 글리콜)를 사용함으로서 원료가격을 획기적으로 낮추는 동시에 작동유 특성을 향상시키고, 기타 윤활제, 방청제, 용제와 어울러 최적의 난연 방청성이 우수한 작동유를 제공하였다.Hydrogels in the hydraulic oil have excellent properties of flame retardancy, but their use is expensive. The present invention uses PAG (polyalkylene glycol) obtained by randomly polymerizing ethylene oxide and propylene oxide as a starting material of ethylene glycol as a middle point, thereby remarkably lowering the raw material cost, improving the operating oil characteristics, and improving the lubricant, To provide an operating oil having an excellent flame retardant antifouling property.
