Friction And Wear Property Of Lubricating Additive Microcapsules And Its Abrasive Tool

According the problem of insufficient lubrication in grinding contact area for high speed grinding process,the existing researches mainly focus on high-velocity jet,scraper plate-aiding-stop air flow,radial coolant jet and impregnation wheel,try to increase the effective supply of grinding fluid.But these methods have the complex structure and unable to save the liquid lubricant and other issues.We attempted to use in-situ polymerization method to prepare lubricating additive microcapsules,which was synthesized with lubricating additive as core material and melamine-formaldehyde resin(MF resin)as shell material.The microcapsules would be taken as filler to make abrasive tool,in order to research the fiction and wear properties of the abrasive tool when grinding with steel ball.The main work and conclusions are as follows:1.Two kinds of microcapsule was synthesized by in-suit polymerization method with oily agent and extreme pressure agent as core materials and melamine-formaldehyde resin as shell materials.Use SEM,FTIR,TG testing it has more than 50%of the core content and stable thermal performance.2.Through the four-ball experiment system inspected the tribological properties of BS-MF and RC2540-MF lubricating additive microcapsule,and analyzed its lubrication mechanism.3.Using hot pressing process prepared the lubrication additive microcapsule abrasive tool which contained the prepared microcapsules as the filler.4.The friction and wear experiment and grinding surface quality indicated the microcapsule abrasive tool could improve the friction and wear performance,but the strength and hardness of the tool needs to be enhanced.
