阳离子分散松香胶的制备和应用

Preparation and Application of Cationic Disperse Rosin Size

介绍了阳离子分散松香胶的制备及应用。将阳离子丙烯酸树脂乳液加入松香与表面活性剂的 熔融物中,作为松香胶的分散剂,得到的松香胶胶乳尺寸细小,乳液稳定性高,且主要以桥联作用在中 性条件下使松香吸附,并在明矾存在下进一步定位和留着。

This paper discusses the preparation of cationic rosin size and its application in the neutral or weakly acidic pH range. As the practical application, it is necessary to add the cationic acrylic copolymer emulsion as the dispersing agent, and the PAE can be used as the special retention aid for the cationic rosin sizing. Another usable retention aid and dispersing agent is the cationic acrylic resin emulsion which is helpful for the adsorption of rosin acid onto filler by the action of bridge connection, then the retention and anchoring size takes place with the existing of alum.
