阳离子型松香施胶剂乳液及其制备方法
摘要：
阳离子型松香施胶剂乳液，由阴离子松香施胶剂乳液和阳离子化剂复合而成，阳离子化剂是含有C＝O羰基的烯类单体聚合而成，经阳离子化改性后得到的、分子量为20000-2000000聚合物，阴离子松香施胶剂乳液占的重量比为50%-95%，阳离子化剂所占的重量百分比为5-50%。阳离子型松香施胶剂乳液的制备方法，即在容器中加入含有C＝O的烯类单体，重量比50%-1000%(以烯类单体为基准)的溶剂，调节pH值至3-7，升温至35℃-70℃，加重量比0.01%-5%引发剂，升温至60℃-95℃，保温不低于0.5h，降温至0℃-35℃得聚合物，对聚合物阳离子化改性，得阳离子化剂，分子量为20000-2000000，取重量百分比为50%-95%阴离子松香施胶剂乳液，将重量比为5-50%的阳离子化剂加入其中。
摘要（英）：

The invention is a cation rosin sizing agent emulsion and its preparing method, compounded of cation rosin sizing agent emulsion and cationation agent, where the cationation agent is polymerized of alkene-type monomer containing carbonyl C=O, and after cationation modification, generates a polymer with molecular weight of 20000-2000000, the weight percent of the emulsion is 50%-95% and that of the cationation agent is 5-50%. Its preparing method: adding the alkene-type monomer and solvent in weight ratio 50%-100% (refer to the alkene-type monomer) to the container, adjusting the pH value to 3-7 and raising the temperature to 35deg.C-75deg.C, adding in initiator in weight ratio 0.01%-5%, raising temperature to 60deg.C-95deg.C, preserving heat to keep the temperature not less than 0.5 h, then lowing the temperature to 0deg.C-35deg.C to obtain a polymer, making cationation agent modification on the polymer, so as to obtain the cationation agent at molecular weight 20000-2000000, taking the above emulsion in weight percent 50-95% and adding the cationation agent in weight ratio 5-50% to the emulsion.
