SDS-AEO15-CTAB微乳模板制备聚丙烯酸酯乳液及影响因素
|
摘要
在十二烷基硫酸钠(SDS)-脂肪醇聚氧乙烯醚(AEO15)-十六烷基三甲基溴化铵(CTAB)微乳体系中,正丁醇(NBA)为助剂作用下由过硫酸钾(KPS)引发进行苯乙烯(St)、丙烯酸丁酯(BA)和丙烯酸(AA)共聚,得到粒径在20 nm,分散性较好的聚丙烯酸酯乳液微球。通过乳液的外观、固含量、耐水性、接触角和粒度以及胶膜的红外(IR)分析和X射线衍射(XRD)结构分析考察了(CTAB/AEO15/SDS)/NBA质量比、CTAB/NBA质量比、St/BA质量比以及KPS用量对乳液及胶膜的影响。用透射电镜(TEM)表征了最优条件下粒子的形貌、大小和分散性。
In the micro emulsion system of sodium dodecyl sulfate( SDS)/Cetyltrimethyl ammonium bromide( CTAB)/aliphatic polyethenoxy ether( AEO15),taking styrene,butyl acrylate and acrylic acid as monomer, n-butanol( NBA) as cosurfactant, potassium persulfate( KPS) as initiator, ployacrylate emulsion which had about 20 nm diameter and favorable dispersibility could be obtained. The comprehensive performances of emulsion,such as,appearance of emulsion,solid content,water resistance,contact angle,particle size, X-ray diffractometer( XRD) and infrared spectrometer( IR) were analyzed to study the influence of( CTAB-AEO15-SDS)/NBA,CTAB/NBA、St/BA and KPS amounts on emulsion and coating.The morphology,size and dispersibility of particles under optimal conditions were showed by TEM image.
