低黄变聚脲微胶囊相变材料的制备及性能表征
Preparation and performance characterization of low-yellowing polyurea microcapsule phase change materials
摘要
Abstract
With isophorone diisocyanate(IPDI)or 2,4-toluene diisocyanate(TDI)as isocyanate,andbutyl stearate as core material,two kinds of polyurea microencapsulated phase change materials were prepared by interfacial polymerization method. Their surface morphology,chemical structure and thermal stability were characterized,and the yellowing properties of microcapsules was analyzed by high temperature drying. Then the two kinds of microcapsules were tested on cotton fabric,and the whiteness of the fabrics obtained at different baking temperatures was tested. the results showed that the prepared microcapsules were sphere with intact and smooth surface. Furthermore,there was no adhesion among IPDI particles,while the surface of TDI microcapsules had certain adhesion phenomenon. TG results showed that the compactness and heat stability of IPDI microcapsules were better than that of TDI microcapsules,and IPDI microcapsules can resist high temperature more than 200℃. The types of isocyanate had a big effect on the yellowing properties of the prepared microcapsules,and the yellowing resistance of microcapsules prepared from IPDI isocyanate was significantly better than those from TDI isocyanate. Especially,the IPDI microcapsules can show better low-yellowing properties,when treated on the fabric.关键词
