摘　　要：研究了乳胶粒径、表面阳离子量不同的NVF-SMDMDAAC共聚物(PNSD)乳液在碱性条件下对桉木浆纸张的增强作用。结果表明:PNSD的纸张增强效果随乳胶粒径的减小而增强,与表面阳离子量和添加量呈正相关,其中粒径最小的PNSD-C1在添加量为0.25%时,纸张干、湿抗张指数和环压指数分别增大18%、54%和26%;表面阳离子量大的PNSD-P4在添加量为0.25%时,可使纸张干、湿抗张指数和环压指数分别增大23%、49%和33%。The strengthening to l：,ucalyptus pulp was studied of NVF- SM-DMDAAC copolymer emulsion （PNSD） with different particle size and sttrface cationic charge. The results show that the strengthening performance increases with the decrease of the emulsion particle size, having a positive correlation with the surface cationic charge and adding dosage. When the adding dosage of PNSD-C1 with the smallest particle size is 0.25%, the paper dry tensile index, wet tensile index and ring crash index are raised by 18%, 54% and 26% respectively; when the adding dosage of PNSD-P4 with the largest surface cationic charge is 0.25%, the paper dry tensile index, wet tensile index and ring crash index are raised by 23%, 49% and 33% respectively.
