摘要
采用黏度计、差热分析和红外光谱分析含钽呋喃树脂的黏度和固化特性,并由此确定合适的浸渍和固化工艺。研究结果表明:在45～50℃范围内,含钽呋喃树脂能保持适合浸渍的低黏度,其固化活化能为61.61kJ/mol,固化反应级数为0.9;固化宜采用阶梯式升温;固化过程中碳碳双键和醚键以及醇羟基等均发生了反应。
The viscosity and curing characteristics of furan-resin containing tantalum were investigated based on the viscosity experiments, DSC and FT-IR analysis. Moreover, the proper impregnation and cure techniques were adopted. The results show that, furan-resin containing tantalum can maintain low viscosity at 45-50 ℃, its apparent activation energy is 61.61 kJ/mol and reaction order is 0.9. The curing should be done by temperature rising step by step. During the process of curing, the synthesized reactions happen between C=C, C-O-C at ring and -OH.
