Gypsum base absorbing composite material and preparation method thereof
The invention relates to a gypsum base absorbing composite material and a preparation method thereof, and belongs to the technical field of building materials. The absorbing composite material includes dry materials and water; the dry materials include gypsum, a wave-transparent aggregate and an absorbing agent; the absorbing agent accounts for 1-20 wt. % of the dry material, the wave-transparent aggregate accounts for 5-25 wt.% of the dry material, the gypsum accounts for 55-94 wt.% of the dry material, and the weight ratio of water to dry materials is 0.5-0.7:1. The preparation method comprises the following steps: mixing the dry materials uniformly, adding water, stirring well, pouring the mixture into a mold, carrying out vibration molding, demoulding 24h after moulding, maintaining under standard conditions and finally drying. The gypsum base absorbing composite material has wide absorbing frequency bandwidth, and high electromagnetic wave absorption capability within the scope of 2-18 GHz; and the production process is simple and feasible.
