| 摘 要： | 采用常压逆转工艺,以甲基丙烯酸-β-3-羟丙酯基三甲基氯化铵(DMHC)为自乳化阳离子单体、苯乙烯(St)为亲油单体、丙烯酰胺(AM)为亲水单体和羟甲基丙烯酰胺(NMAM)为交联剂,经氧化-还原引发共聚,然后加入松香,借助于反应形成的阳离子无皂苯丙乳液作分散乳化剂,制得阳离子苯丙共聚物分散松香胶。结果表明:当pH值为6～6.5、w[助留剂Al2(SO4)3]=0.5%、w[阳离子聚丙烯酰胺(CPAM)]=0.2%和w(阳离子分散松香胶施胶剂)=1.2%(相对于干浆料而言)时,将此阳离子分散松香胶应用于混合浆抄纸体系中,采用逆向施胶,纸张施胶度达84s,环压指数达7.36N·m/g,较空白样提高了17.7%。

| Abstract: | The cationic styrene-acrylate copolymer dispersion rosin size was prepared by normal pressure inversion process,and with DMHC as self-emulsifying cationic monomer,St as lipophilic monomer,AM as hydrophilic monomer,NMAM as cross linker,through initiation copolymer of oxidation and reduction,then added rosin,and with the help of cationic soap-free styrene-acrylate emulsion for reaction formation.The results showed whenpH value was 6-6.5,the content of aluminum sulfate(retention aid) was 0.5%(relative to dry p... |
