【摘要】 以4,4’—二马来酰亚胺基二苯甲烷、二烯丙基双酚A、溴化环氧树脂、双氰胺等为主要原料，采用预聚法工艺，通过不同比例共混的方法获得性能优良改性树脂体系。以玻璃纤维为增强材料，改性树脂体系为基体树脂，丙酮作为主要溶剂，制备了储存稳定性优良的胶液和半固化片，压制得到的覆铜箔层压板具有良好的力学性能和电气性能。通过实验及分析确定了最佳的树脂配方体系，利用傅立叶红外光谱仪、差示扫描量热分析仪等分析手段对改性树脂体系的凝胶特性、反应特性、固化机理及反应动力学进行了详细的研究，并对覆铜箔层压板成型工艺中胶液的配制、浸胶、干燥以及热压工艺进行了深入研究，确定了各道工序的主要影响因素并最终确定了适宜的成型工艺。更多还原

【Abstract】 A modified resin system with high performance has been obtained by copolymerization of 4,4’-diphenylbismaleimide, diallylbisphenol A, bromize epoxy, dicyandiamide with suitable proportion and prepolymerization. Using the modified resin system as matrix, and the glass fiber as reinforcement, and acetone as main solvent, the impregnant and half-cured sheet with fine properties are prepared, what’s more, the copper clad laminate based on the modified resin system show good mechanical and dielectrical properties. The finest resin system is settled down through experiment and analysis. The solubility, curing kinetic and mechanism of the modified resin are studied by FTIR infrared and DSC apparatus, as well as the confect of impregnant, impregating, dryness and laminate processing of the copper clad laminate.更多还原
