Abstract: Brominated maleic rosin was produced from maleic rosin and bromine, and then brominated maleic rosin epoxy resin was synthesized by ring-open and ring-closing reaction of brominated maleic rosin and epichlorohydrin. The influence of reaction conditions was discussed, such as ring-open reaction temperature, mole ratio of material, concentration of NaOH and so on. The product which was prepared under suitable conditions had following property: epoxy value 0.30 mol/(100g) ^-1.The product was characterized by FT-IR and ¹H-NMR. Brominated maleic rosin epoxy resin was cured by DDM. The test has proved that the curing product of brominated maleic rosin epoxy resin has better flame retardation.

摘要：

以马来松香和液溴为原料，合成了溴化马来松香;再与环氧氯丙烷发生酯化反应、闭环反应，合成了溴化马来松香环氧树脂。结果表明，在适宜的条件下，合成的环氧树脂的环氧值为0.30 mol·（100 g）^-1。 用红外光谱（FT-IR）、核磁共振谱（¹H NMR）和元素分析法对产物进行了表征。采用固化剂4，4′–二氨基二苯甲烷（DDM）对产物进行了固化。实验证明，溴化马来松香环氧树脂固化物具有较好的阻燃性。
