摘要
(CN106432703) 本​发明​公开​了​种​高​固体​含量​羟基​聚酯树脂​及其​制备​方法​与​应用。其​制备​方法​是:(1)向​反应​釜​中​加入​配方​量​的​小分子​多元​醇、聚醚​多元​醇、酸酐​和​溶剂,搅拌​升温​至​90‑110℃反应​3‑4h,至​体系​透明;(2)添加​环​氧化​合物​和​催化剂,保持​温度​在​90‑120℃反应​4‑12h​待​酸值​达到​10mgKOH/g​以下,降温​出料​得到​高​固体​含量​羟基​聚酯树脂。该​树脂​固体​分​达到​79%以上,黏度​为​400‑1900mPa·s。该​羟基​聚酯树脂​制备​方法​简单,无​副产物​生成,成本​低廉,反应​条件​温和,适合于​大规模​生产。采用​该​羟基​聚酯树脂​制备​的​双​组​份​聚氨酯​涂料​的​施工​固​含​高,VOC​含量​低,涂​膜​硬度​高、丰满​度​高、保​光​保​色​性好​和​耐​介质​性能​优异。
