| Abstract: | The polyethylene wax(PE) was oxidized with O2 using zinc stearate as catalyst.Experiment shows that at 160 ℃～170 ℃,800 L/h of air flux,1.0%～2.0% of catalyst amount and 6 hours’ oxidation,the oxidized PE(OPE) with 20.0 mg KOH/g～25.0 mg KOH/g acid number can be prepared.IR shows that polar groups for example-COOH,-CO,etc have been imported into the molecular of PE.Phase inversion and shearing were used in the cationic emulsifying;the stability and particle diameter of the emulsion were analyzed.Emulsifying experiment shows that using combination emulsifiers of OS-15 and 1631,the amount of which is 15% and 5% respectively according to the mass of OPE,90 ℃～95 ℃ of emulsifying temperature,continuously stirring for 40 min～60 min,steady cationic OPE,emulsion can be prepared,the average particle diameter of which is 5.8 μm. |
