摘要
本文通过相转移工艺研制了含微细分散石墨,83—21分散稳定剂等的节能油添加剂(GRT节能油添加剂)。 实验室试验结果表明,这种添加剂具有良好的胶体稳定性,在贮存期内不会产生沉降。摩擦磨损试验及负荷承载能力试验说明,在商品内燃机油中加入GRT节能油添加剂之后,摩擦和磨损显著降低,负荷承载能力则明显提高。实际行车试验表明,在汽车机油中加入GRT节能油添加剂之后,可节约燃料油5％以上。 同时还用俄歇能谱仪等分析仪器探讨了GRT节能油添加剂的减摩抗磨机理。
An energy-saving oil additive (GRT additive)containing finely dispersed graphite, 83-21 dispersant-stabilizer and other additives has been developed by means of phase-transfer process.
Experimental results show that this colloidal additive is highly stable and will not settle out in storage. Remarkable reduction of friction and wear, an increase of load carrying capacity by adding GRT into commercial engine oil are detected. More than 5% fuel saving in road tests has been obtained by the incorporation of GRT and engine oils.In addition, the friction and wear reduction mechanism of GRT additive has been probed by means of AES and other analytical methods.
