Abstract
In this study,the structures of polyether esters synthesized from different functional polyethers(fatty alcohol polyether,propylene glycol polyether,glycerol polyether)and fatty acids were characterized,and the defoaming properties of three functional polyether esters were focused studied.The results showed that when the fatty acid was stearate acid,the fatty alcohol polyether ester defoamer had the best defoaming performance with the octadecanol as polyether initiator,the atomic weight ratio of EO to PO in polyether was 3:7.The propylene glycol polyether ester of POEO and EOPOEO block(EO at the end of the polyether chain segment)had a good defoaming effect.When the molecular weight of glycerol polyether was 3 000,the defoaming effect of the glycerol polyether ester was the best.After optimization,octadecyl polyether ester had good deforming effect in low temperature household paper white water,while propylene glycol polyether ester and glycerol polyether ester had good deforming effect in high temperature boxboard and culture white water,respectively.When the mass concentration of three polyether ester solutions reached 0.6 g/L,all the surface tension was 27.0 mN/m.关键词
