修磨润滑油的研制

Research on Grinding Lube

为了替代进口修磨油,对板材修磨油进行了研制。70N基础油能够兼顾黏度与闪点(开口)的要求,可作为修磨油的基础油。通过对配方稳定性,极压性和沉降性的考察,对极压剂和沉降添加剂进行了筛选。研制的修磨油由70N基础油,6.0%的硫化脂肪,0.10%的复合沉降添加剂(0.05%醚酯型表面活性剂+0.05%阳离子聚合物)及0.5%的酚型抗氧剂组成,其典型理化性能为40℃运动黏度13.47 mm2/s,闪点(开口)201℃,烧结负荷3923 N,达到了拟定的技术指标。应用表明,研制的修磨油具有良好的清洗性能和沉降性能,润滑性能优良,能够满足修磨工艺的润滑要求,可以替代进口修磨油,实现了修磨油的国产化。(图3表5参考文献3)

In order to replace the imported grinding lube,the plate grinding lube was developed.70N Stock could meet the requirements of viscosity and flash point(opening),so it could be used as Stock of grinding lube.Through the investigation for stability,extreme-pressure performance and settling performance of formula,the extreme-pressure additives and sedimentation additives were screened.The researched grinding lube was composed of 70N Stock,6.0%sulfurized fat,0.10%complex sedimentation additives(0.05%ether ester surfactant+0.05%cationic polymer)and 0.5%phenolic antioxidant.Its typical physiochemical performances were kinematic viscosity 13.47 mm2/s at 40℃,flash point(opening)201℃,weld load 3923 N,which had reached the proposed technical specifications.The application showed that the developed grinding lube had good cleaning performance,sedimentation performance and excellent lubrication performance.It could meet the lubrication requirements of the grinding process,and could replace the imported grinding lube to realize the localization of the grinding lube(.Charts3 Tables5 References3)
