Magnesium oxysulfate cement-based wave-absorbing material and preparation method thereof
The invention discloses a magnesium oxysulfate cement-based wave-absorbing material and a preparation method thereof. The cement-based wave-absorbing material comprises the following components in parts by weight: 65-75 parts of light calcined magnesia powder, 15-25 parts of a wave-absorbing material matrix, 10-20 parts of magnesium sulfate heptahydrate, 0.1-1 part of dolomite fine powder, 0.1-1 part of a modifier, 0.1-1 part of silica fume and 0.1-1 part of an early strength agent. Wherein the wave-absorbing material matrix comprises the following components according to a mass ratio: graphite powder: ferrite powder = (1-2): 1. According to the invention, the coordination effect of the magnesium oxysulfate cement base, the ferrite and the graphite is fully utilized in raw material design, so that the excellent wave-absorbing material is obtained, the wave-absorbing effect is achieved on the basis of retaining the original light weight and high strength, and the wave-absorbing material is green, environment-friendly and efficient in performance.
本发明的一种硫氧镁水泥基吸波材料及其制备方法，该水泥基吸波材料重量份配比为：轻烧氧化镁粉65～75份，吸波材料基体15～25份，七水硫酸镁10～20份，白云石细粉0.1～1份，改性剂0.1～1份，硅灰0.1～1份，早强剂0.1～1份；其中，吸波材料基体包括组分为，按质量比，石墨粉：铁氧体粉末＝(1～2)：1。本发明在原料涉及上充分利用硫氧镁水泥基，铁氧体，石墨协调作用，充分发挥三者的协同作用，以获得优异的吸波材料，保留原有轻质高强基础上，达到吸波效果，绿色环保且性能高效。
