実施例1及び実施例2は本発明による実施例であるが、表1、2に示す他の例は本来、比較例である。
表1、2の配合物について、酸化安定性を測定するため、回転式圧力容器酸化テスト(RPVOT)(以前は回転式高圧噴霧容器酸化テスト(RBOT)として知られていた)(ASTM D2272)を行なった。
Examples 1 and 2 are examples according to the present invention, but the other examples shown in Tables 1 and 2 are originally comparative examples.
For the formulations in Tables 1 and 2, the rotary pressure vessel oxidation test (RPVOT) (formerly known as the rotary high pressure spray vessel oxidation test (RBOT)) (ASTM D2272) was used to measure oxidation stability. I did it.
更に、Wolfストリップテスト(以前はDIN 51392として知られていた)を以下に述べる改良法で行なった。
以前、DIN 51392は、傾斜金属板にテストエンジンオイルをポンプ送りし、金属板上のエンジンオイルの熱/酸化沈着物生成傾向を測定していた。前記テストで規定された、油量、ポンプ送り速度、金属板温度及びテスト時間は、それぞれ200ml、50ml/hr、250℃、12時間であった。
In addition, a Wolf strip test (formerly known as DIN 51392) was performed with the improved method described below.
Previously, DIN 51392 pumped test engine oil onto an inclined metal plate and measured the tendency of the engine oil on the metal plate to produce heat / oxidation deposits. The oil amount, pump feed rate, metal plate temperature, and test time specified in the test were 200 ml, 50 ml / hr, 250 ° C., and 12 hours, respectively.
このテストの繰返し性を改良すると共に、潤滑油組成物がコンプレッサーにおいて充分な流体力学的膜条件下で受ける熱/酸化応力型に一層密接にシミュレートさせるため、表1、2の例で使用した条件は、油量を150ml、ポンプ送り速度を50ml/hr、金属板温度を205℃、テスト時間を24時間に変更した。
表1及び表2から、本発明による配合物は、良好な沈着制御性ばかりでなく、回転式圧力容器酸化テスト(RPVOT)において顕著な性能も示すことが明らかである。
Used in the examples in Tables 1 and 2 to improve the repeatability of this test and more closely simulate the thermal / oxidative stress types that the lubricating oil composition undergoes under sufficient hydrodynamic membrane conditions in the compressor. The conditions were changed to an oil amount of 150 ml, a pump feed rate of 50 ml / hr, a metal plate temperature of 205 ° C., and a test time of 24 hours.
From Tables 1 and 2, it is clear that the formulations according to the invention show not only good deposition control properties, but also outstanding performance in the rotary pressure vessel oxidation test (RPVOT).
