| 摘 要： | 研制了适合树脂膜熔渗工艺(RFI)的酚醛树脂体系,采用动态DSC技术和固化度的测试,建立了改性树脂体系的固化动力学模型,研究了等温条件下固化度/温度/时间关系以及固化度/玻璃化转变温度关系,通过平板拉丝法研究树脂的凝胶过程,得出凝胶时间和温度之间的关系,回归得到凝胶时的固化度为αgel=53.33％,并以此计算出凝胶时的Tg,gel=48.64℃,在此基础上绘制了该体系的TTT图.

| Abstract: | The aim of this work is to prepare an novel phenolic resin(PF)film suitable for RFI process and generate its TTT cure diagram.Dynamic DSC technique was conducted to establish curing kinetic model that was used to describe the relationship of curing degree-time-temperature and of curing degree-glass-transition temperature on isothermal conditions.Establishing the relationship between the glass-transition temperature and curing degree allowed the determination of the vitrification lines of the resol resins.In... |
