中文摘要：
采用常压逆转法．在实验室分别制备了两种性能稳定的阳离子分散胶CDRZ-1和CDRZ-2。其中CDRZ-1以松香和石蜡为原料．CDRZ-2则以松香、改性石油树脂和石蜡为原料。将两种不同的分散胶应用于混合办公废纸浆施胶．对比了两种胶料的施胶效果，结果发现使用改性石油树脂能够大大地改善施胶效果。
英文摘要：
Two different kinds of sizing named CDRZ-1 and CDRZ-2 respectively were prepared by normal pressure inversion process. The raw material for CDRZ-1 were nature rosin and olefin, and for CDRZ-2 was nature rosin, olefin and modified petroleum resin. In this study, two kinds of sizing were used for MOW deinked pulp, The result showed the CDRZ-2 was much more effective compared with the CDRZ-1.
