在对环氧树脂胶粘剂固化机理研究的基础上,使用双酚A与环氧氯丙烷合成环氧树脂使其能用于铸造领域。利用合成的树脂制作型砂试样,并对几项关键指标进行了性能检测。结果表明,用其所制成的型砂具有较好的强度及适当的可使用时间。
Based on the research of curing mechanism of epoxy adhesive, epoxy resin is synthesized by using bisphenol A and epichlorohydrin to make it be used in casting field. The synthetic resin was used to make the sand sample, and the performance of several key indexes was tested. The results show that the sand made with it has better strength and proper working time.
