水分散聚合制备两性PAM纸张增干强剂及应用
Preparation and application of APAM as dry strengthening agent by aqueous dispersion polymerization
摘要
Abstract
Using acrylamide (AM ) ,methacryloyloxyethyl trimethyl ammonium chloride (DMC) and itaconic acid as comonomers ,carboxymethyl cellulose(CMC) modified with epi-chlorohydrin as dispersing agent ,ammonium persulphate (APS ) as initiator .Amphoteric polyacry lamide (AmPAM ) was synthesized via water dispersion polymerization .The effects of w(DMC) ,w(SMAS) ,w(AM) ,w(dispersing agent) ,w(APS)and polymerization tempera-ture on paper strength were investigated .The results show that the optimum condition is as follow :w(DMC)=4% ,w(SMAS)=0 .8% ,w(AM)=18 .0% ,w(dispersing agent)=13 .0% , w (APS)=0 .35% ,temperature 80 ℃ .The ring crush strength and tensile strength of paper w ere elevated by 38 .04% and 30 .15% respectively .关键词
