摘 要:用環(huán)氧樹(shù)脂E-44作為反應性的增容劑,采用熔融共混方法制備了尼龍6(PA6)/廢印刷電路板非金屬粉(N-PCB)復合材料。研究了E-44用量、擠出溫度以及N-PCB粉末的粒徑大小對PA6/N-PCB復合材料力學(xué)性能和熱變形溫度的影響。對復合材料抽提殘留物的紅外分析實(shí)驗結果表明E-44與PA6/N-PCB復合材料中PA6以及N-PCB粉末表面發(fā)生了化學(xué)鍵合。添加1.25份E-44的PA6/N-PCB復合材料與純PA6相比,其拉伸強度、拉伸模量、彎曲強度和彎曲模量最大增幅分別為 29%、49%、73%和72%,熱變形溫度提高了42.8℃,但其韌性降低。與未加增容劑相比,其拉伸強度、彎曲強度和缺口沖擊強度最大增幅分別為 9%、8%和43%,熱變形溫度提高了9.3℃。 |

Abstract:Polyamide 6(PA6) matrix composites,reinforced with nonmetals recycled from waste printed circuit boards(N-PCB)and compatibilized with epoxy resin(E-44),was prepared by the melt blending method. The effects of E-44 dosage,extrusion temperature and N-PCB particle sizes on the mechanical properties and heat distortion temperature of PA6/N-PCB composites were investigated. The results showed that there were chemical reactions occurred between the components of PA6/N-PCB composites,proved by both FT-IR analysis and the extraction experiment. The maximum increment of tensile strength,tensile modulus,flexural strength and flexural modulus of the PA6/N-PCB composites were 29%,49%,73% and 72%,respectively,compared to that of pure PA6 while the heat distortion temperature increase by 42.8℃. However,the toughness of the composites was decreased. The tensile strength,flexural strength,impact strength and heat distortion temperature of PA6/N-PCB composites increased by 9%,8%,43% and 9.8℃,respectively,comparing to that without compatibilizer-E44.
