Foam electromagnetic shielding material and preparation method thereof
The invention provides a preparation method of a foam electromagnetic shielding material, which comprises the following steps: mixing cinnamomum camphora fruit powder and corn flour according to a mass ratio of 10: (0.5-1.5) to obtain a mixture A, mixing FeCl3 and silicone oil according to a mass ratio of 10: (0.5-1.0) to obtain a mixture B, mixing the mixture A and the mixture B according to a mass ratio of 1: 1, and stabilizing at room temperature for 24 hours after mixing; adding silver nanowires, uniformly mixing to obtain a mixture C, and transferring the mixture C into a mold for pressing; curing the mixture C; transferring into a calcining furnace, heating to 900 DEG C at the speed of 200 DEG C/h, and keeping the temperature for 7-8 hours; and cooling, and repeatedly washing with a 0.2 mol/L hydrochloric acid solution. The prepared foam electromagnetic shielding material takes the cinnamomum camphora fruit powder as a raw material, effective utilization of waste resources is achieved, and the prepared material is high in porosity, good in shock resistance and good in electromagnetic shielding effect and can be used for various industries.
本发明提供了一种泡沫电磁屏蔽材料的制备方法，包括以下步骤：取香樟果实粉和玉米粉按质量比为10:(0.5‑1.5)进行混合获得混合物A，取FeCl3和硅油按质量比为10:(0.5‑1.0)进行混合获得混合物B，将混合物A和混合物B按质量比为1:1进行混合，混合后在室温下稳定24h；加入银纳米线，混合均匀，获得混合物C，移入模具中压紧；将混合物C进行固化；转移至煅烧炉中，以200℃/h的速度加热至900℃，保温7‑8h；冷却，用0.2mol/L盐酸溶液反复洗涤即得。本发明制备的泡沫电磁屏蔽材料以香樟果实粉为原料，实现废弃资源的有效利用，制备的材料孔隙率高，防震性好，同时电磁屏蔽效果也好，可被用于多种行业。
