摘要:由双马来酰亚胺(BMI)和氰酸酯(CE)树脂合成了一种高玻璃化转变温度(Tg)、低介电常数(ε)、低介质损耗因数(tanδ)的双马来酰亚胺三嗪树脂(BT树脂),并以高性能树脂聚苯醚(PPE)对其进行改性,制备了ε=2.76,tanδ=0.0025的改性BT树脂。FTIR分析表明:CE、BMI分别自聚而成为各自均聚物,PPE以聚合物合金的形式分散在BT树脂中,BT树脂改性前后的DMA曲线均显示出两个玻璃化转变温度。由PPE改性BT树脂制备的复合材料具有优异的介电性能(ε=3.51,tanδ=0.0055)和低吸水率(0.37%/24h),改性BT树脂与玻璃纤维之间具有良好的界面黏结性能。
A kind of bismaleimide-triazine (BT) resin with high glass transition temperature (Ts ), low dielectric constant (ε) and low dielectric loss (tanδ) was synthesized from bismaleimide (BMI) and cyahate (CE). And a lower ε and dielectric loss BT resin ( ε = 2.76, tanδ = 0. 0025 ) modified with high-performance polyphenylene ether (PPE) was prepared. The result showed that CE and BMI polymerized respectively and generated their own homopolymers. PPE was dispersed in BT resin in the form of polymer alloy. The dynamic mechanical analysis (DMA) curves of BT resin, as well as the modified BT resin, showed two Ts. Its composite modified by PPE had excellent dielectric properties (ε = 3.51, tanδ = 0, 0055), low water absorption (0. 37%/24h) and good interface adhesion between resin and glass fibers.
