松香和松香酯乳液制备的研究进展

Advances in preparation of rosin and rosin ester emulsion

国内制备松香和松香酯乳液主要采用常温常压转相法,其关键是乳化剂的选用。国内主要采用聚氧乙烯醚类表面活性剂制备松香乳液,国外则普遍采用阳离子高分子分散剂来制备阳离子松香乳液。国内有关松香酯乳液制备的研究较少,其需求主要依靠进口,国外大部分公司采用非离子型改性的阴离子型乳化剂。

Rosin and rosin ester emulsion is widely used in the pressure sensitive adhesive industry.Rosin emulsion is prepared at the room temperature and normal pressure,and choosing proper emulsifier is the key factor.In China,polyoxyethy- lene ether is widely used as the emulsifier of rosin emulsion,but cation polymer dispersant is mostly used abroad.The little studies on the rosin emulsion were made in China,and most companies used modified anion emulsifier abroad.
