以开发同时满足耐湿性和耐热性的模塑料为目的,研究了含有双环戊二烯、芴基、萘基等化学结构的树脂以及苯并噁嗪固化剂对模塑料性能的影响。结果表明,制得的环氧树脂/苯并噁嗪/酚醛树脂的模塑料,具有低吸水率和最高的玻璃化转变温度(Tg),能够满足高达225℃的耐热性要求,在满足JEDEC—MSL3耐湿性条件下,可以满足175℃使用的耐热性要求,吸水率为0.07%,弯曲强度为127MPa,弯曲模量为13.0GPa。
In order to develop a molding material that satisfies both moisture resistance and heat resistance, the effects of resins containing chemical structures such as dicyclopentadiene, fluorenyl, naphthyl, and benzoxazine curing agents on the properties of the molding compound have been investigated. The results show that the prepared epoxy / benzoxazine / phenolic resin molding compound has low water absorption and the highest glass transition temperature (Tg), can meet the heat resistance up to 225 ℃, meet JEDEC -MSL3 moisture-resistant conditions, to meet the 175 ℃ heat resistance requirements, water absorption of 0.07%, flexural strength of 127MPa, flexural modulus of 13.0GPa.
