Wet-ground copper slag cement-based electromagnetic shielding composite material and preparation method thereof
The invention relates to a wet-ground copper slag cement-based electromagnetic shielding composite material and a preparation method thereof. The preparation method comprises the following steps: adding water into copper slag for wet grinding, and obtaining wet-ground copper slag slurry for standby application; immersing the recycled carbon fibers into water, uniformly dispersing the recycled carbon fibers into the water, adding a dispersing agent, uniformly stirring, adding a defoaming agent, and carrying out ultrasonic treatment for a period of time to obtain a carbon fiber dispersion liquidfor later use; taking and mixing portland cement, the wet-ground copper slag slurry, waste tire rubber powder, the carbon fiber dispersion liquid and the water reducing agent solution, and evenly mixing to obtain the wet-ground copper slag-based cement-based electromagnetic shielding composite material. According to the invention, industrial wastes such as copper slag, recycled carbon fibers andwaste tires are utilized, so that the mechanical property and electromagnetic shielding property of the cement-based composite material are effectively improved, and the cost is reduced while the green and environment-friendly scientific development concept is realized.
本发明涉及一种湿磨铜渣的水泥基电磁屏蔽复合材料及其制备方法，上述制备方法包括如下步骤：向铜渣中加水湿磨，得湿磨铜渣浆料，备用；将回收碳纤维浸入并均匀分散于水中，然后加入分散剂，搅拌均匀后再加入消泡剂，超声处理一段时间，得碳纤维分散液，备用；取硅酸盐水泥、湿磨铜渣浆料、废弃轮胎橡胶粉末、碳纤维分散液以及减水剂溶液，混合均匀，即得一种湿磨铜渣的水泥基电磁屏蔽复合材料。本发明中通过对铜渣、回收碳纤维、废弃轮胎这些工业废弃物的利用，有效提高了水泥基复合材料的力学性能和电磁屏蔽性能,在实现绿色、环保的科学发展理念的同时,也降低了成本。
