摘　　要：通过检测相同辐照条件下皮革表面温度变化,研究了具有隔热功能真皮革与普通真皮革的隔热性差异。结果表明:辐照0~20 min时,随着辐照时间增加,隔热真皮革与普通真皮革表面温度均快速上升,平均升温速率分别为1.85、2.59℃/min,隔热真皮革的升温速率明显低于普通真皮革,这表明隔热真皮革吸热性要明显比普通真皮革弱;辐照20 min,隔热真皮革、普通真皮革表面温度均达到初始峰值58.8、74.8℃,前者比后者低16.0℃;辐照超过20 min后,两者表面升温速率均显著减缓,直到60 min,表面温度分别达到最大64.7、82.8℃,此时隔热真皮革比普通真皮革最大低18.1℃。由此可见,隔热真皮革具有良好的隔热性。The differences of heat insulation between real leather with heat-insulating function and ordinary real leather was studied by measuring the leather surface temperature change under the same irradiation condition.The results show that the surface temperature of heat-insulating real leather and ordinary real leather increase rapidly with the increase of irradiation time from 0 to 20 min,and the average heating rate is 1.85 and 2.59℃/min respectively.The heating rate of heat-insulating leather is obviously lower than that of ordinary leather,which indicates that heat absorption of heat-insulating real leather is smaller than that of ordinary real leather.After irradiating for 20 min,the surface temperatures of both heat-insulating real leather and ordinary real leather reaches initial peaks of 58.8 and 74.8℃,the former is 16.0℃lower than the latter.After irradiating for more than 20 min,the surface heating rate of both of leather samples slowes down significantly,until 60 min,the maximum surface temperatures reaches 64.7 and 82.8℃respectively.At this time,the heat-insulating real leather is 18.1℃lower than ordinary real leather.It can be seen that heat-insulating real leather has good heat insulation.
