【摘要】 本文从光引发剂、涂膜厚度、单体、颜料几个方面研究了影响红、黄、兰三种体系紫外光固化涂料（ UVCC）的固化速率的因素．当光引发剂含量为最佳值时，固化速率可达最大值．不同颜料对固化速率的影响不同，随着颜料含量的增加，固化速率都降低．膜厚对固化速率的影响很大，膜越厚，固化速率越低．一定含量的多官能度单体，可提高 UVCC的固化速率．更多还原

【Abstract】 Factors which influenced curing velocity of ultraviolet curing coating are discussed including photoinitiator, thickness of coating film , monomer , pigment． It has been proven that there exists an optimum content for a given photoinitiator to get the highest curing rate． Curing rate will decrease as the content of pigment increase． The thicker coating film is, the lower curing rate is． A monomer with multifunction can fasten curing process if the concentration of monomer in the system is not too high．更多还原
