摘要: 以十六烷基三甲基溴化铵(CTAB)为乳化剂,正戊醇为助乳化剂,甲基丙烯酰氧乙基三甲基氯化铵(DMC)为阳离子单体,偶氮二异丙基咪唑啉盐酸盐(V-44)为引发剂,单体St/MMA/BA/MAA/DMC质量比为3.4/21.3/28.4/35.5/11.4,转速控制在180~230 r·min-1,反应温度控制在70~75 ℃时,得到阳离子苯乙烯-丙烯酸酯(以下简称为苯丙)微乳液,并利用红外光谱仪和差示扫描量热仪对微乳液进行了表征;粒径分析测得平均粒径为48 nm。将制得的苯丙微乳液用于纸张表面施胶后,纸张抗水性Cobb (30 s)值为16.5,抗张强度和表面强度比纸张施胶前分别增加约35.0%和40.6%。

Abstract: Adopting cetyltrimethylammonium bromide as surfactant,n-pentanol as auxiliary emulsifier,methacryloxyethyltrimethylammonium chloride (DMC) as cationic monomer,2,2′-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride as initiator,with mass ratio of the reactants of styrene/methyl methacrylate/butyl acrylate/methacrylic acid/DMC monomer of 3.4/21.3/28.4/35.5/11.4;under agitation speed of 180-230 r·min-1 and polymerization temperature of 70-75 ℃,the cationic styrene-acrylate microemulsion was prepared.The product was characterized by FTIR and differential scanning calorimeter.Average particle size was measured as 48 nm.Application test of the prepared styrene-acrylate microemulsion on surface sizing of paper showed that the water resistance Cobb (30 s) value achieves 16.5,and tensile strength and surface strength of the paper increases 35.0% and 40.6% respectively as compared with that before the sizing.

Key words: surface sizing agent, cationic, microemulsion
