| 摘要:本研究以纸为基材，利用聚乙烯醇（PVA）溶液分散相变微胶囊（PCM）制备涂布液，将其涂布在纸上制备负载相变微胶囊的纸基复合材料（C-PCM），用于加热不燃烧卷烟（HNB）降温段。并优化了PVA质量分数、相变温度及涂布工艺对C-PCM性能的影响。结果表明，涂布液最佳制备条件为PVA质量分数5%，PCM相变温度45 ℃，涂布液固含量20%，此条件下制备的C-PCM可将滤嘴最高温度降至37.4 ℃，降温效果显著优于国外市售产品。此外，C-PCM还具备良好的抗张指数（57.4 N·m/g）、亲水性（水接触角44.2°）和防油性，综合性能满足HNB卷烟的实际需求。在尽量保持复合材料降温性能的同时，添加适量的CaCO3填料可以替代相变微胶囊以节约成本。 |
| Abstract:In this study, a novel paper-based composites containing phase change microcapsules (C-PCM) was fabricated for the cooling segment of heat not burn (HNB) cigarettes. Using paper as the substrate, a coating solution was prepared by dispersing phase change microcapsules (PCM) in a polyvinyl alcohol (PVA) solution, which was then applied onto the paper. Through optimization of PVA concentration, phase change temperature, and coating parameters, the coating solution optimal preparation conditions were determined as: PVA solution mass fraction was 5%, PCM phase change temperature was 45 ℃, coating solution solid content was 20%. The C-PCM prepared under this condition reduced the maximum temperature of the cigarette filter to 37.4 ℃, significantly outperforming commercially available HNB cigarette filters. The phase change enthalpy of C-PCM reached 120.3 J/g at this coating condition, confirming excellent heat absorption capability. Additionally, C-PCM exhibits favorable tensile index (57.4 N·m/g), hydrophilicity (water contact angle 44.2°), and oil resistance. When maintaining the cooling performance of C-PCM as much as possible, adding an appropriate amount of CaCO3 thermal conductive filler could replace an appropriate amount of phase change microcapsules to save costs. |
