摘要

使用白藜芦醇基活性酯(三甲苯酰化白藜芦醇,TTR)与萘型环氧(1,6-二羟基萘,NEP)反应制备得到萘型环氧树脂(NEP/TTR).用红外光谱表征NEP/TTR结构,结果显示NEP/TTR无明显羟基吸收峰,说明该环氧固化反应没有产生羟基,有利于提升树脂的介电性能表现和降低吸水率.树脂的应用性能测试结果表明:NEP/TTR在 10 MHz下的介电常数为 3.46,介电损耗为0.0094,24 h吸水率仅为0.15%,性能表现优异;NEP/TTR的T5%达到 365℃,表明该树脂具有非常好的耐热性.综上所述,所制备的NEP/TTR是一种性能优异的低介电环氧树脂.

Abstract

Naphthalene-based epoxy resin(NEP/TTR)was prepared by reacting resveratrol-based active esters(tri-toluoylated resveratrol,TTR)with naphthalene-based epoxy(1,6-dihydroxynaphthalene,NEP).Firstly,the internal structure of NEP/TTR was characterized by infrared spectroscopy,and the results showed that NEP/TTR had no obvious hydroxyl absorption peaks,indicating that no hydroxyl groups were generated by the epoxy curing reaction,which was conducive to the enhancement of the resin's dielectric performance and the reduction of water absorption.The further test results showed that NEP/TTR had an excellent performance with a dielectric constant of 3.46 and a dielectric loss of 0.0094 at 10 MHz,and a 24h water absorption of 0.15%.In addition,the T5%of NEP/TTR reached 365 ℃,indicating that the resin had good heat resistance.In conclusion,the prepared NEP/TTR is a low dielectric epoxy resin with excellent performance.
