摘　　要：简要介绍了氨基模塑料的基本生产工艺流程,探索了玻璃纤维、纳米蒙脱土、丁腈橡胶粉、玉米淀粉等对氨基模塑料耐电击穿性能和缺口冲击强度的影响。实验结果表明,玻璃纤维作为增强剂对氨基模塑料的电气强度提高效果最为明显,而缺口冲击强度呈下降趋势;纳米蒙脱土的加入使氨基模塑料性能都有提高;玉米淀粉的加入对氨基模塑料的电气强度影响不明显,对缺口冲击强度略有提高;而丁腈橡胶的加入使氨基模塑料的电气强度明显下降,缺口冲击强度提高比较明显,但随丁腈橡胶加入量的增加影响不显著。改性后的氨基模塑料的电气强度能超过17 kV/mm,缺口冲击强度最高可以达到2.7 kJ/m2,最佳耐电压时间在100 s以上。This paper introduced the basic amino molding production process to explore the glass fibers, nano-MMT, butyronitrile rubber powder, corn starch molding on the amino dielectric breakdown properties and notched impact resistance. The results showed that the glass fiber as reinforcing agent for amino molding plastics for electrical breakdown strength was most obvious, and notched impact strength decreased, the addition of nano-MMT amino molding performance improved, corn starch added to the amino molding plastics for electrical breakdown strength was not obvious, there was a slight increase of notched impact strength, the addition of amino butyronitrile rubber powder mold plastics for electrical breakdown strength significantly decreased, notched impact strength increased obviously, but the addition of butyronitrile rubber powder with no significant effect on its increase. The intensity of anti-electrical breakdown strength exceeded 17 kV/mm alter reshaping, the highest notched impact strength can be achieved at 2.7 kJ/m^2, the best withstand voltage time was above 100 s.
