摘　　要：合成了一种以异氰酸酯为"桥"的硅氧烷-丙烯酸酯型光-潮气双固化保形涂料。探讨了引发剂、稀释剂等对其光固化行为的影响,结果表明,所合成的保形涂料存在较明显的氧阻聚现象,加入三丁胺可以抑制部分氧阻聚的影响。A kind of UV-moisture dual curable conformal coating based of silicone and acrylate with isocyanate bridge was prepared. The effects of initiators, dilutes on UV-curing behavior of the coatings were investigated by DPC. The results show that I1800 be effective UV-initiator for the coatings, oxygen affected the curing degree of the coatings seriously, and active amine monomer, such as tri-butyl amine, can suppress oxygen inhibition for the coatings partly.
