二烯丙基双酚A对低黏度氰酸酯树脂的改性研究
STUDY ON THE MODIFICATION OF DIALLYL BISPHENOL A TO CYANATE ESTER RESIN WITH LOW VISCOSITY
摘要
Abstract
The modification of dimly lbisphenol A (DBA) to low viscosity cyanate ester resin was investigated by the test of viscosity-temperature characteristics,differential scanning calorimetry,mechanical test,thermal gravimetric analysis,dynamic thermomechanical analysis,water absorption and dielectric performance.The results show that the viscosity of CE modified by DBA slightly increased,but it still satisfied the viscosity requirement for hot melt method.DBA can catalyze the curing reaction of CE and increase the conversion ratio.DBA of appropriate amount can toughen the cured resin,the impact strength and flexural toughness of the resin with 10％ DBA were 179％ and 165％ times higher than those of the unmodified resin,respectively.The heat resistance,moisture resistance and dielectric property of CE modified by DBA all decreased slightly compared with the unmodified,but still met the application requirements.It is concluded that the optimum addition of DBA is 5％ ～ 10％.关键词
