稳定剂对高固含量石蜡乳液稳定性的影响

The effect of the stabilizing agent on the stability of high solid content wax emulsion

在石蜡乳液体系中，加入0．2％PVP、0．1％可溶性淀粉、0．2％膨润土或0．1％无水MgSO4均能改善石蜡乳液的稳定性，可使固含量为50％的石蜡乳液在3000r／min的转速下离心30min不分层，常温下，乳液的表观粘度为370～630mPa·s。

Adding 0.2% PVP,0.1% soluble starch ,0.2% bentonite or 0.1% anhydrous MgSO4 can improve the stability of wax emulsion. Wax emulsion with 50% solid content was obtained and not stratified at the 3 000 r/min by centrifugating 30 rain. At ambient temperature, its apparent viscosity was 370 ～ 630 mPa·s.
