中文摘要:
      通过测定不同黏度的聚α-烯烃(PAOs)、硅油及其不同调和比例混合基础油在-50~50℃时的运动黏度,研究调和基础油的黏度随调和组分和温度的变化规律。结果表明,调和基础油的实测黏度远小于按国际通用黏度模型计算得到的黏度值;黏度相差较大的PAO油与硅油调和时,调和基础油的高低温运动黏度均在两调和组分的黏度之间变化;而黏度接近的PAO油与硅油调和时,在一定成分范围内,调和基础油的低温运动黏度低于两调和组分的黏度,其低温流动性更加优异。特定的PAO油与硅油能够相互用作低温降黏剂进一步改善润滑油的低温性能。通过引入分子间相互作用对这一现象进行了解释。
英文摘要:
      The viscosity composition temperature variation was investigated by measuring the kinematic viscosity of poly(α-olefins) (PAOs) and silicone oils and their blend oils with different blending ratio in the temperature range from -50℃ to 50℃.The experimental results show that the viscosity value of the blend oils is much less than the calculated value based on the international general viscosity model.When mixed with PAOs and silicone oils whose viscosity is much different,the high and low temperature viscosity of the blend oils varies between that of PAOs and silicone oils.When mixed with the base oils whose viscosity is similar,the low temperature viscosity of the blend oils is smaller than that of each single component in the certain ratio range.The blend oils show more excellent low temperature fluidity than each single component.The PAOs and silicone oils could be used as viscosity decreasing agent with each other at low temperature to further improve the low temperature property of lubricating oil.The intermolecular interaction was introduced to explain this phenomenon.
