松香活性基团的改性及其在废纸脱墨浆中的施胶应用研究

Modification of Rosin Active Groups and Application of Sizing in Waste Paper Deinked Pulp

综述了林产品松香的提取,对松香在造纸行业的应用进行了总结概述,并对其中应用较广、优势较明显的阳离子松香乳液进行了深入的探讨。列举了阳离子乳化松香胶的制备方法,松香官能团(如羧基)的改性,以及阳离子乳化松香胶在废纸脱墨浆中的应用实例。

The extraction of the forest products rosin and the application of rosin in the pulp and paper industry were summarized.The cationic rosin emulsion,which was widely used and had obvious advantages,were discussed deeply.The preparation methods of cationic rosin emulsion,the modification of functional groups(such as carboxyl groups)and the application of cationic emulsified rosin size in deinked pulp were listed.
