摘要:

采用双螺杆挤出机制备了聚酰胺6(PA6)/50 %(质量分数,下同)玻璃纤维(GF)、PA66/50 %GF、PA56/50 %GF 3种高含量GF增强阻燃PA复合材料,对比研究了红磷、溴系、磷氮3种阻燃体系下复合材料的力学性能、阻燃性能和激光打标性能。结果表明,不同阻燃体系对复合材料的力学性能有明显影响,吸水平衡后,PA66复合材料的力学性能保持率最高;PA56复合材料在3种阻燃体系中均表现出比PA6、PA66复合材料更好的阻燃性能;红外激光和紫外激光的打标效果存在明显不同,而在阻燃体系和激光光源相同的条件下,PA6、PA66和PA56 3种PA复合材料的激光打标效果没有明显差异。

Abstract:

Three types of reinforced flame?retardant polyamide (PA) composites with a high content of glass fiber were prepared using a twin?screw extruder, which included PA6?, PA66? and PA 56?matrix composites with 50 wt% glass fiber. The mechanical properties, flame retardant properties and laser marking properties of the composites were studied comparatively under three flame retardant systems including red phosphorus, bromine, and phosphorus?nitrogen. The results indicated that the flame retardant systems had obvious effects on the mechanical properties of the composites. The PA66 composites obtained the highest retention of mechanical properties after water absorption equilibrium. The PA56 composites exhibited better flame?retardant performance the PA6 and PA66 composites. The laser marking effect of infrared laser and ultraviolet laser was obviously different, and however, it showed no obvious difference among PA6, PA66 and PA56 under the same flame?retardant systems and laser source.

Key words: high content glass fiber, polyamide, reinforcement modification, flame retardant, laser marking
