A strong difference in the physico-chemical properties of the plastic lubricants studied was found in this study through pressure drop, thermal analysis, vibration damping, texture hardness and rheological measurements. Oxidation aging of the lubricant sample containing rapeseed oil additive was proposed. Its higher thermal sensitivity was simultaneously confirmed by frequency dependent complex shear modulus of elasticity measurements as well as by rheological testing. Rapeseed oil modified lubricant showed a higher decrease in both storage and moduli losses due to a temperature increase from 16 to 26 ° C compared to the rapeseed oil free sample. Simultaneously, the flow curves were shifted to the higher shear stresses (for plastic lubricant without rapeseed oil additive) typical for rheopectic fluids. For the rapeseed oil modified lubricant, the flow curves were shifted to the lower shear stresses, indicating its thixotropic fluid behaviour. The synthetic lubricant without rapeseed oil additive exhibited higher dissipative rheological behaviour as reflected by decreasing first resonance frequency peak position compared to the rapeseed oil modified lubricant as obtained from vibration damping measurements. It was found that the synthetic lubricant exhibited better vibration damping properties and mechanical energy dissipation into heat due to its higher viscous friction than the rapeseed oil modified lubricant under experimental conditions.

通过压降，热分析，振动阻尼，织构硬度和流变学测量，在本研究中发现了所研究的塑料润滑剂的理化性质之间存在很大差异。提出了含菜籽油添加剂的润滑油样品的氧化老化。通过频率相关的复数剪切弹性模量测量和流变测试，同时证实了其较高的热敏性。与无菜籽油样品相比，由于温度从16升高到26°C，菜籽油改性润滑剂显示出更高的存储和模量损失降低。同时，流变曲线转移到流变流体典型的较高的剪切应力（对于不含菜籽油添加剂的塑料润滑剂）。对于菜籽油改性润滑剂，流动曲线转移到较低的剪切应力，表明其触变性。与通过振动阻尼测量获得的菜籽油改性润滑剂相比，不含菜籽油添加剂的合成润滑剂表现出更高的耗散流变行为，这通过降低第一共振频率峰值位置得到反映。发现在实验条件下，合成润滑油比菜籽油改性润滑油具有更高的粘性摩擦，因此具有更好的减振性能和机械能转化为热量。与通过振动阻尼测量获得的菜籽油改性润滑剂相比，不含菜籽油添加剂的合成润滑剂表现出更高的耗散流变行为，这通过降低第一共振频率峰值位置得到反映。发现在实验条件下，合成润滑油比菜籽油改性润滑油具有更高的粘性摩擦，因此具有更好的减振性能和机械能转化为热量。与通过振动阻尼测量获得的菜籽油改性润滑剂相比，不含菜籽油添加剂的合成润滑剂表现出更高的耗散流变行为，这通过降低第一共振频率峰值位置得到反映。发现在实验条件下，合成润滑油比菜籽油改性润滑油具有更高的粘性摩擦，因此具有更好的减振性能和机械能转化为热量。
