摘要
为了研究不同芯材的微胶囊及其对纺粘—熔喷—纺粘(SMS)非织造布墙纸调温性能的影响,利用原位聚合法,分别以正十八烷、正二十烷及两种烷烃以质量比1∶1混合的混合烷为芯材,以三聚氰胺-尿素-甲醛(MUF)树脂为壁材,制得三聚氰胺-尿素-甲醛/正十八、二十、混合烷相变微胶囊。通过SEM、DSC等手段分析其样貌特征、热焓值等。通过干法涂层工艺将3种微胶囊整理至SMS织物上,制得智能调温织物。通过SEM、红外测温仪、强力测试仪、织物透气量仪等仪器测试方法,研究整理后织物的表面形貌、强力变化、透气率变化和不同芯材微胶囊调温效果的差异。结果表明,相变微胶囊形状均一,粒径分布集中,球形表面光滑。经相变微胶囊整理后的织物具有一定的调温蓄热功能,升降、温过程中均有较为明显的平台期,混合芯材具有调温范围广、作用时间长的优点。断裂强力与拉伸断裂伸长率均有提高,这些都有利于作为墙纸的使用性能。
The properties of compound core of phase change microcapsules and the thermo-regulating property of SMS nonwoven wallpaper treated by phase change microcapsules with different core were studied.By situ polymerization method,the phase change microcapsules(PCMs)with different core were based on n-octadecane,n-eicosane and the mass ratio of 1to 1of two them,whose shells were melamine-urea-formaldehyde.The surface morphology and enthalpy were analyzed by scanning electron microscopy(SEM)and differential scanning calorimetry(DSC).The smart thermostat fabrics were prepared by SMS nonwovens,which were treated by PCMs with different core by apad-dry-cure method.The surface morphology,breaking strength,permeability and temperature changing rate of treated fabrics were characterized by way of SEM,infrared thermometer,tensile tester and air permeability tester.The results indicated that the PCMs with smooth surface were of uniform shape,and particle size distribution was concentrated.The treated fabric was of super regenerative thermostat function which result in the slowing down of temperature changing rate.And the compound core was of wide range thermostat and long duration of action.Both of the breaking strength and breaking elongation were increased,which were beneficial to the performance of wallpaper.
