Preparation and Performance of Green Complex Calcium Sulfonate Grease
In order to solve ecological problems,green development has become a global consensus,and the development of green lubricants is accelerating.A green complex calcium sulfonate grease was prepared by using high base number calcium sulfonate with natural vegetable oil(rapeseed oil+soybean oil)as the base oil and dodecylbenzenesulfonic acid and acetic acid as the accelerators,and its performance was evaluated.The green complex calcium sulfonate grease prepared has a dropping point higher than 330 ℃,0.25％ of steel mesh oil separation rate,weld load of 4900 N,and has good thixotropic property,anti-rust property,water resistance,high temperature performance and tribological characteristics(frictional coefficient and anti-wear performance).(Charts9 Tables3 References10)
