一种环氧树脂体系的加温固化参数研究

摘要

The parameters of heating curing of the 850S epoxy resin system were studied based on the curing degree reflected indirectly by the surface hardness of cured resin casting.At the same time the curing state of the resin casting must be investigated when the method was used.The results show that 50℃/4 h and 55℃/4 h are appropriate parameters of heating curing of the 850S epoxy resin system.%聚合物的表面硬度与固化度之间存在一定的联系,测试浇注体表面硬度可以间接反映其固化度.结果表明,研究环氧树脂(850S)体系的加温固化参数必须同时考查浇注体的固化状态,50℃/4 h或55℃/4h均为850S体系较为合适的加温固化参数.
