为了提高双马来酰亚胺树脂单体的溶解性和降低预聚体粘度,实现低成本的 RTM成型工艺加工,设计并合成了叔丁基改性双马树脂3,3′-二叔丁基-4,4′-二苯甲烷双马来酰亚胺(BBDM)树脂。采用红外光谱仪和元素分析仪,进行了结构表征。溶解性实验表明,该新型树脂单体在普通溶剂中的溶解性得到明显改善。预聚体粘度测定和熔点测定表明,预聚体粘度达到了树脂传递模塑工艺(RTM)对树脂体系粘度的要求(0.20~0.28 Pa·s),原有树脂的耐热性也得到了保留。

In order to improve the monomer solubility of bismaleimide resin,lower the resin prepolymer’s vis-cosity and make the bismaleimide resin easy to manufacture by the RTM molding process which was knowen as a new low cost process,3,3′-ditert-butyl-4,4′-diphenylmethane bismaleimide (BBDM).The chemical struc-tures of the products were confirmed by infrared spectroscopy and elemental analysis.Solubility experiments show that the solubility of the new resin monomer was significantly improved in common solvents.Data of the prepolymer viscosity and melting points show that the viscosity of the prepolymer meets the requirements of the resin transfer molding process (RTM)(0.20-0.28 Pa·s)and the heat resistance of original resin has been also retained.With the development of our society,more and more high performance composite materials used in special areas,such as aerospace,high-temperature protection industry and microelectronic field,are needed.
