摘　　要：当夏季温度超过30℃时,口红会因高温发生融化,甚至断裂。为了防止口红在夏季因高温融化,利用3D打印技术制备了光敏树脂的口红外壳,选用十二醇和月桂酸作为中间蓄冷介质,采用加热混合法制备了十二醇–月桂酸相变蓄冷材料。利用瞬态平面热源法导热仪、差示扫描量热仪和蓄冷试验对相变蓄冷材料的导热系数、相变温度、相变潜热和蓄冷特性进行了研究。结果表明:十二醇–月桂酸相变材料的导热系数为0.2258 W/(m·K),相变温度为18.6℃,相变潜热为179.1 kJ/kg,适合作为口红外壳的相变蓄冷剂。在30℃的高温天气条件下,蓄冷口红外壳能够持续蓄冷大约3 h,可以确保口红不会因高温融化,能够延长口红的使用寿命。When temperature is over 30℃in summer,the lipsticks are melt and easy to be broken due to the high temperature,therefore,a"lipstick coat"is needed to prevent this happening.The"lipstick coat"was prepared with 3D printed photosensitive resin cell containing dodecyl alcohol and lauric acid as phase change cold storage material.The thermal conductivity,phase change temperature,latent heat of fusion and cold storage characteristics were studied by means of transient plane heat source thermal conductivity instrument,differential scanning calorimetry and practical test.The results show that the thermal conductivity of this phase change material is 0.2258 W/(m·K),phase transition temperature is 18.6℃,the latent heat of fusion is 179.1 kJ/kg.It is suitable to be used as cold storage material for lipstick shell.When the environment temperature is as high as 30℃,cold storage lipstick shell can keep the lipstick cool for three hours,which ensures that the lipstick will not be melt in hot days and prolongs the service life of lipstick.
