摘要:

以热塑性弹性体(SEBS)为基体,以四种不同石蜡(OP44E、Paraffin46-48、OP50E、OP55E)作为相变材料,通过物理吸附和平板硫化法制备得到了具有不同相变温度的石蜡/SEBS复合相变材料热疗鼻贴。测量了复合相变材料的硬度、相变温度和相变潜热以及热疗鼻贴的控温效果。结果表明:四种石蜡/SEBS复合相变材料热疗鼻贴在高于相变温度状态下邵氏硬度均接近0 HA,十分柔软,使得热疗鼻贴与鼻部可紧密贴合。其相变温度与石蜡相当,相变焓值高于135 J·g-1。80 ℃水温条件下仅需1.5 min可使鼻贴从常温快速加热至60 ℃,是一种方便快捷的加热方式。热疗鼻贴的合适相变温度为46~48 ℃,10 mm厚度的Paraffin46-48/SEBS 相变材料热疗鼻贴能够维持鼻部温度43 ℃以上15~20 min的热疗要求。本研究有效地改进了局部热疗在鼻炎症状治疗中存在的温度和时间问题,推动了热疗法在在鼻炎治疗中的应用。

Abstract:

Using thermoplastic elastomers(SEBS)as the base, four different paraffin(OP44E, Paraffin46-48, OP50E, and OP55E)phase change materials were prepared. These composite materials produced thermal therapy nasal strips with different phase change temperatures that were obtained by physical adsorption and a flat-plate vulcanization system. The hardness, phase change temperature, phase change latent heat of the composite materials, and temperature effects of thermal therapy nasal strips were measured. The results demonstrate that the hardness of the four types of thermal therapy nasal strips are close to 0 HA in the state above the phase change temperature and are in a very soft state such that the thermal therapy nasal strip and one's nose could fit closely together. The phase change temperature is comparable with that of paraffin, and the phase change value is >135 J·g-1. It is a convenient and fast approach to heat the thermal therapy nasal strip from room temperature to 60 ℃ in only 1.5 min under 80 ℃ water temperature conditions. The appropriate phase change temperature of the thermal therapy nasal strip is from 46 to 48 ℃. Paraffin 46—48/SEBS thermal therapy nasal strips with a thickness of 10 mm can meet the requirements of heat therapy lasting 15—20 min with the nasal temperature maintained at>43 ℃. This study effectively improved the temperature and time problems existing in the treatment of rhinitis symptoms with localized heat therapy and promoted the application of effective heat therapy in rhinitis treatment.
