Abstract

本发明属于尼龙1010/聚丙烯稀土塑料合金的制备工艺，本发明利用稀土引发下聚丙烯接枝马来酸酐的接枝物中的酸酐基团与尼龙1010酰胺基中-NH2发生化学反应，进而改善聚丙烯与尼龙1010共混相容性，制备的尼龙1010/聚丙烯稀土塑料合金抗张强度60～65MPa，弯曲模量1000～1300MPa，缺口冲击强度70～90J/M，吸水率0.5～1%，收缩率降低。

Description

聚癸二酰癸二胺/聚丙烯稀土塑料合金工艺
本发明属于聚癸二酰癸二胺(简称尼龙1010)/聚丙烯稀土塑料合金的制备工艺。
尼龙1010是很重要的工程塑料之一，其吸水率虽比尼龙6和尼龙66都低，但吸水率也大于2％，用做某些工程构件或制件吸水率偏高，收缩率偏大，尺寸稳定性差。另外尼龙1010价格昂贵，开发应用受到限制。
尼龙1010为极性高聚物，聚丙烯为非极性，二者共混不相溶，在熔融共混时，发生严重相分离，合金力学性能差，抗张强度25～30MPa，伸长率123％～137％，Izod缺口冲击强度30～40J/M，没有应用价值。
本发明的目的是提供一种利用稀土引发下聚丙烯接枝马来酸酐的接枝物中的酸酐基团与尼龙1010酰胺基中-NH2发生化学反应，进而改善聚丙烯与尼龙1010共混相溶性，制备尼龙1010/聚丙烯稀土塑料合金的工艺。
本发明的方法是将尼龙1010按重量比95～60％与聚丙烯重量比5～40％，再加入稀土催化引发下聚丙烯接枝马来酸酐的接枝物(简称稀土接枝物)，其量为前两者总重量的5～10％，将尼龙1010，聚丙烯和稀土接枝物放入螺杆挤出机或捏合机中熔融反应，反应温度190～230℃，挤出速度2mm/分～6mm/分，挤出物经气冷造粒，制成的尼龙1010/聚丙烯稀土塑料合金，抗张强度55～65MPa，伸长率250％～320％，弯曲强度60～65MPa，弯曲模量1000～1300MPa，缺口冲击强度70～90J/M，吸水率0.5～1％，收缩率降低。
本发明提供的实施例如下：
实施例1：
取尼龙1010 95g与聚丙烯5g，再加入稀土接枝物(稀土催化引发下聚丙烯接枝马来酸酐的接枝物)5g，三者一起熔融共混，挤出速度为2mm/分，测其抗张强度为65MPa，伸长率270％，吸水率0.5％，弯曲强度64MPa，弯曲模量为1290MPa。
实施例2：
尼龙1010 90g与聚丙烯10g，再加入稀土接枝物10g，反应加工条件同实施例1，其合金性能抗张强度为58MPa，伸长率300％，吸水率0.8％，冲击强度90J/M。
实施例3：
尼龙1010 70g与聚丙烯30g，再加稀土接枝物10g，反应加工条件同实施例1，其合金抗张强度55MPa，伸长率为320％，吸水率0.5％，冲击强度80J/M，弯曲模量为1000MPa。
