The effects of different viscosity of base oils,primary thickeners,auxiliary thickeners,content of adhesives on the performance of water resistance of the steel wire rope greases were studied by using the determination method of grease resistant to water spray.The results indicate that the water resistance of the steel wire rope grease is significantly improved with the increasing of base oil viscosity,especially when the viscosity is in 25~56 mm 2/s.Polypropylene is better than Poly Ethylene as the primary thickener in terms of improving the water resistance.As an auxiliary thickener of the steel wire rope greases,the more the number of microcrystalline wax additives,the better the resistance to water is,but this effect will be tended to flatten when the microcrystalline wax content is more than 4%.Along with increasing in the number of grease adhesive polyisobutylene(PIB)or olefin copolymer(OCP)in proportion,the water resistance of steel wire rope grease is improved.But when the percentage of grease adhesive is more than 5%,the water resistance becomes worse.Polyisobutylene(PIB)is better than olefin copolymer(OCP)in improving the water resistance of the steel wire rope grease.
