Fire resistance performance of Fe_3O_4/polythene magnetic composite

以高密度聚乙烯为基体树脂,选用FeCl3为填料,使用丙烯酸作为分散剂,采用熔融原位法制备铁氧粒子/聚乙烯复合材料。利用扫描电镜和电子衍射分析该复合材料结构,结果显示制备得到铁氧粒子/聚乙烯复合材料,且磁性粒子均匀分散在树脂基体中。采用电子万能试验机和氧指数测定仪研究了铁氧粒子/聚乙烯复合材料力学性能和阻燃性能,实验结果表明,该结构的磁性高分子材料不仅获得了较好的力学性能,同时还具有良好的阻燃性能。

This article introduces the process of preparing Iron particles/polyethylene composite through using High Density Polyethylene as matrix resin, FeCl2 as filler and Acrylic Acid as Dispersant by the Melting-Blending method. Through utilizing the modern testing approaches such as Electronic Universal Testing Machine, FTIR, XRD and Oxygen index analyzer, the structural and mechanical properties of Iron particles/polyethy- lene composite material are systematically researched while fo- cusing on the research of the flame retardant property of Corn posite when FeCI3 exist concurrently. The result of the experi- ment shows that under the condition of using Acrylic Acid as Dispersant, FeCl2 can be dispersed in the matrix basin in the form of nanoparticles and a certain amount of as filler can effectively enhance the tension strength and impact strength of Iron particles/polyethylene composite material, and the flame re tardant property of Iron particles/polyethylene composite material is conspicuously better than that of Pure Polyethylene.
