矿物型重负荷车辆齿轮油GL-5 75W-90的研制

Study on the Mineral Based Heavy Duty Vehicle Gear Oil GL-5 75W-90

以泰州石化自产高压加氢基础油为主要原料,筛选不同类型黏度指数改进剂及齿轮油复合功能剂,调合得到重负荷GL-5 75W-90车辆齿轮油。并对其黏度指数、抗泡性、布氏黏度、KRL剪切稳定性等关键性能进行了考察,筛选出符合新国标GB 13895-2018质量标准的调合方案。确保所研制的GL-5 75W-90车辆齿轮油具有优异的黏温性能、低温性能,及抗剪切性,以满足各种类型工况要求。

Different types of viscosity index improvers and gear oil compound functional agents were applied to prepare the GL-5 75 W-90 heavy duty vehicle gear oil by taking CNOOC Taizhou hydrogenation base oil as raw materials.Key properties such as viscosity index,antifoam,Brookfield viscosity and KRL shear stability etc.were investigated.Based on the results,the appropriate formula selected for GL-5 75 W-90 heavy duty vehicle gear oil can meet the GB 13895-2018 standard requirements.The developed oil has excellent viscosity-temperature performance,low temperature performance and shear stability to meet the requirements of different working conditions.
