摘要

以不同比例的10-(2,5-二羟基苯基)-10-氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO-HQ)和3,4-环氧环己基甲基-3,4-环氧环己基甲酸酯(ERL4221)进行反应，合成不同含磷量的阻燃型环氧树脂(EP-HQ)，并用红外光谱及核磁共振对其结构进行了表征。测试了不同磷含量对环氧树脂的环氧值、热性能、阻燃性能和紫外光固化性能的影响。结果表明，同ERL4221相比，EP-HQ的热稳定性和阻燃性有所提高，当磷的质量分数为1.5%时，EP-HQ的氧指数达到24.9%，垂直燃烧达到了V-1，且具有较高的光固化活性。

Abstract

UV-curable phosphorus-containing epoxy resin was synthesized with chain-extension of (3,4-epoxycyclohexyl)methyl-3,4-epoxycyclohexanecarboxylate (ERL4221) and 2-(6-oxido-6H-dibenz(c,e) (1,2)- oxaphosphorin-6-yl)-1,4-benzenediol (DOPO-HQ) at different stoichiometric ratios. The structures of these resins were characterized by IR and 1H-NMR. The influences of different phosphorus contents on the epoxy value of the epoxy resin, thermal properties, flame retardancy, and UV curing properties were investigated. The results showed that the thermal stability and flame resistance increased compared with those of the unmodified ERL4221 epoxy resin under the same conditions. When the phosphorus mass content was 1.5%, the limiting oxygen index (LOI) reached 24.9, vertical burning achieved V-1 levels, and had a higher light curing activity.Cited
