摘　　要：文章以端乙烯基聚硅氧烷(ViPDMS)、甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)三者共聚物为壁材,有机颜料铜酞菁蓝(PB)为芯材,采用细乳液聚合制得了颜料纳米胶囊(P(DMS-Acr)/PB)。考察了ViPDMS用量对颜料单体分散液黏度及表面张力的影响和乳化剂十二烷基硫酸钠(SDS)、共稳定剂十六烷(HD)、PB、ViPDMS等因素对P(DMS-Acr)/PB形态的影响。结果表明,随着ViPDMS和PB含量的增加,单体分散液的黏度增高,致使P(DMS-Acr)/PB的平均粒径明显增大,粒径分布变宽,体系稳定性变差。乳化剂SDS能提高聚合体系稳定性,从而可部分抵消ViPDMS和PB加入导致的粒径增大、分布变宽和体系失稳趋势。在优化工艺基础上所制P(DMS-Acr)/PB有望用于丝绸涂料印花领域。Vinyl polysiloxane(ViPDMS),methyl methacrylate(MMA)and butyl acrylate(BA)copolymers were used as the wall material,and organic pigment copper phthalocyanine blue(PB)was used as the core material to prepare pigment nano-capsules(P(DMS-Acr)/PB)via miniemulsion polymerization.The effects of ViPDMS dosage on dispersion liquid viscosity of pigment monomer and surface tension were studied and the effects of the factors such as twelve sodium alkyl sulfate(SDS).hexadecane(HD),PB and ViPDMS on morphology of P(DMS-Acr)/PB were investigated.It is found that ViPDMS with the increase of ViPDMS and PB content,dispersion liquid viscosity of the monomer rose,thus leading to the obvious increase of average particle size of P(DMS-Acr)/PB,increase of size distribution width and poor system stability.The emulsifier SDS could improve the stability of polymerization system,which can partially counteract the increase of particle size,increase of size distribution width and the instability of the system caused by the addition of ViPDMS and PB.The P(DMS-Acr)/PB prepared on the basis of optimal process is expected to be used for pigment printing of silk.
