木质素及溴化木质素对合成环氧树脂热性能的影响
Effects of lignin and brominated lignin on the thermal properties of epoxy resin
摘要
Abstract
Tetrabromobisphenol A epoxy resin is widely u sed in the electronics and aerospace industries, but application is limited due to high costs. The aim of this study was to determine the effects of lignin and bromi-nated lignin on thermal properties of epoxy resin. Lignin and brominated lignin were mixed with bisphenol A and reacted with epichlorohydrin to produce epoxy resin. Then, thermal properties of the epoxy resin were test-ed. Results showed that when the lignin content (M:M) was 10％, temperatures for mass loss were higher than that of bisphenol A epoxy resin (the initial temperature was 4.4 ℃ higher and the peak temperature was 68.9℃ higher), and the mass loss was 3.8％ lower. Temperatures for mass loss of brominated lignin-bisphenol A e-poxy resin (Br-LBEP) were higher than that of LBEP (initial temperature 112.2 ℃ higher and peak tempera-ture 93.7 ℃ higher) with the mass loss being 2.1％ lower. Thus, brominated lignin improved thermal properties and could be used instead of tetrabromobisphenol A to produce high thermal property epoxy resin.关键词
