HZY2型合成刹车油基础液的制备与应用研究

Preparing HZY2 brake oil and its application

论述了ＨＺＹ２型高级合成刹车油所需的改性甘醇基础液的配方组成及其使用性能的研究工作。试验结果表明３＃基础配方体系具有较高的平稳回流温度和适宜的低温（－４０℃）粘度，并且与刹车系统的橡胶密封皮碗配伍良好，完全符合ＧＢ１０８３０－８９标准要求。从而赋予了ＨＺＹ２型合成刹车油优良的高温抗气阻性能和低温流动性能，提高了汽车行驰制动安全性。

Diethylene glycol, triethylene glycol, polyethylene glycol and diluent are mixed to form the basic solution of HZY2 brake oil. Performance test shows that the smooth and stable recycle boiling point, viscosity at -40℃, average IHRD values at 70℃ for 120 hours and 120℃ for 70 hours, and the change values of brakes' rubber parts size fall in with the demands of China Standard GB10830-89 respectively.
