摘要

以脲醛树脂为囊壁

氯化铵为催化剂

采用原位聚合法包覆了固体石蜡

合成了相变储能微胶囊

并将其添加到水泥、涂料中制成建筑复合材料.采用傅里叶红外光谱仪分析了微胶囊的化学结构

通过差示扫描量热仪和扫描电子显微镜表征了微胶囊及复合材料的储热性能、表观形貌及微观状态.结果显示:该方法可有效包覆石蜡形成微胶囊

其形貌光滑圆润

与建筑基材相容性良好

得到的复合建材储热能力较佳

在节能领域有广泛用途.

Abstract

Phase change microcapsules were synthesized by in-situ polymerization using ammonium chloride as curing agent and urea-formaldehyde resin as shell material while liquid/solid paraffin as core material.The microcapsules were added to building materials such as cements and some coating materials to form composite material for building.Chemical structures of the microcapsule composition were analyzed by Fourier transform infrared spectroscopy.The heat storage ability

surface morphology and the microscopic state of the microcapsules were studied through Differential Scanning Calorimetry(DSC) and Scanning Electron Microscopy(SCM).The results show that urea-formaldehyde resin can effectively capsulize an organic material of paraffin and form a smooth and round surface morphologically

and the microcapsules can interface well with the building materials.The composite materials have good capacity of thermal energy storage and can be widely used in the energy saving field.
