Preparation of Leather Wax by Oxidized Paraffin Wax

A mass proportion paraffin and microcrystalline wax was adopted as raw material, and under certain conditions catalyzed oxidation reaction took place,a sample which qualify and performance similar to that of natural carnauba wax was obtained.By using oxidation wax as experimental material and water as solvent,under the surfactants'action,after the reaction of emulsification,polishing and decontaminating wax for leather was prepared.Then some factor's effects on stability of emulsifying wax,such as emulsifier type,quantity,stirring speed,emulsifying time and emulsifying temperature were discussed.The results show that when the dosage of oxidation wax: the mass fraction of auxiliary,emulsifier and emulsifier is 1∶0.3∶0.000 2,emulsifying time is 20 min,stirring speed is 500～1 000 r/min,emulsifying temperature is 85～90 ℃,the wax for leather whose feature is well-distributed,well function and low cost which compared with the natural carnauba wax is obtained.
