摘要
采用聚乙烯一甲基丙烯酸缩水甘油酯(EGMA)作为增容剂和增韧剂,利用反应增容技术制备了PA6/EGMA的合金。通过试验确定了PA/EGMA合金汽车保险杠新材料的最佳配方,提高合金的综合性能。该合金具有良好的加工性能,较高的抗冲击性能并易于喷涂,是综合性能优良的抗冲击新产品。PA6/EGMA合金表现出非粘弹性高分子材料在高速冲击时仍然具有较高的韧性的特性。
The PA6/EGMA alloy was prepared using EGMA as compatibilizer and toughener in a reactive extrusion process. The optimum processing parameter and formulation for the PA6/EGMA alloy of Car Bumper new materials were determine, blends of the alloy could be improved. The alloy had a good process ability, higher impact resistance and spray-paint easily, being a new product excellent comprehensive performance impact. The PA6/EGMA alloy Show the non-viscoelastic polymer materials in high speed impact still has higher toughness properties.
