More Information
Summary:The present invention relates to an automobile brake fluid composition and, more particularly, to an automobile brake fluid composition including: 30 to 60 wt% of boric acid ester compound; 30 to 60 wt% of alkylene glycol alkyl ether; and 0.05 to 10 wt% of fatty polyalkylene glycol (OSP). The OSP-containing automobile brake fluid composition according to the present invention allows a high boiling point of a brake fluid to be maintained for a long period of time by reducing an atmospheric moisture absorption amount of the brake fluid, and thus can lengthen a brake fluid replacement cycle and can improve corrosion prevention performance, metallic wear resistance, and master cylinder operation. 본 발명은 자동차용 브레이크액 조성물에 관한 것으로서, 더욱 상세하게는 붕산에스테르 화합물 30 ~ 60중량%; 알킬렌글리콜 알킬에테르 30 ~ 60중량%; 및 지용성 폴리알킬렌글리콜(OSP) 0.05 ~ 10중량%를 포함하는 자동차용 브레이크액 조성물에 관한 것이다. 본 발명의 OSP를 함유하는 자동차용 브레이크액 조성물은 브레이크액의 대기 중 수분 흡습량을 저감시켜 브레이크액의 높은 비등점이 장기간 유지되게 함으로써 브레이크액의 교환 주기를 길게 하고, 부식방지 성능, 금속 내마모성 및 마스터실린더의 작동을 향상시킬 수 있다.
