摘要
双马来酰亚胺树脂(BMI)具有优良的耐热性、尺寸稳定性及单体合成方便、成本较低等优点,但单体熔点高,溶解性较差,固化物交联密度大,机械性能较差,限制了其应用。通过多胺对BMI的改性,使BMI树脂熔点降低,溶解性得到改善,加工成型容易,综合性能提高,在层压板、模压复合材料、工程塑料、粘接剂、粉体涂料等领域得到了广泛应用。多胺对BMI的改性可分为直接体系和间接体系两大类。讨论了两类改性体系的研究及应用。
Diamine or polyaminemodified BMI resin had lower meltpoint,better solubility and better process performance so it was widely useful for multilayered lamination,molding material,abrasive material,engineeting plastics,adhesive,sealing material,powder coating,etc.In this paper two polyaminemodified BMI resin systems,indirect system and direct system,and their application were discussed.
