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180～230r·min-1，反应温度控制在70～75℃时，得到阳离子苯乙烯一丙烯酸酯（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48nm。将制得的苯丙微乳液用于纸张表面施胶后，纸张抗水性Cobb（30S）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％。
Adopting cetyhrimethylammonium 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 mcthacrylate/ 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 urn. 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.
