相变储热微胶囊的制备及在智能纺织品上的应用
Preparation of thermal energy storage microcapsule by phase of change and the application in intelligent textiles
摘要
Abstract
Polyurethane phase change thermal storage microcapsules were prepared by interfacial polymerization using butyl stearate as core material,2,4-toluene diisocyanate (TDI) and pentaerythritol as reactive monomers.The results of scanning electron microscope show that the microcapsules are homogeneous,and the density of the microcapsu[e is the best when the mass ratio of TDI/pentaerythritol is 2 ∶ 1.The melting temperature and the melting enthalpy of the phase change microcapsules were 22.5 ℃ and 86.37 J/g and it can keep good heat performance at room temperature.It was used for the preparation of intelligent textiles.The effect of binder concentration and dosage of microcapsule were studied for fabric weight.The influence of curing temperature and baking time on the wash ability of the fabric was discussed.The finishing process for phase change microcapsules was determined through process optimization,the microcapsule is 70 g/L,binder 60g/L,curing temperature and baking time 120 ℃ and 3 min respectively.The fabric finished has a good temperature adjusting performance near the phase transition temperature of phase change materials.关键词
