采用脱水蓖麻油制聚酰胺,将之应用于环氧树脂固化体系中,并进行了DSC测试、耐热性测试和力学性能测试,综合考察了该聚酰胺与环氧树脂固化体系(DCOPA/EP)的适宜配比。研究结果表明:当DCOPA/EP固化体系以质量比0.8∶1.0混合时,固化反应最完全,固化物的耐热性能最高,冲击、弯曲及剪切性能最强。
Polyamide was prepared from dehydrated castor oil and applied to the epoxy resin curing system. DSC, heat resistance and mechanical properties were tested. The effects of polyamide and epoxy curing system (DCOPA / EP ) The appropriate ratio. The results show that when the mass ratio of DCOPA / EP is 0.8: 1.0, the curing reaction is the most complete, the cured product has the highest heat resistance and the strongest impact, bending and shearing properties.
