Coal gangue novel lightweight wall material and preparation method
The invention discloses a coal gangue novel lightweight wall material and a preparation method thereof. The novel lightweight wall material is prepared from the raw materials by mass percent of 43-84.5% of coal gangue, 5-20% of fluxing agent, 0.5-2% of foaming agent and 10-35% of perlite by the steps of mixing, spray granulation, die filling and sintering. The wall material disclosed by the invention has the characteristics of light weight and high impact strength and a lightweight, thermal-insulation, durable and environment-friendly novel lightweight wall material, wherein the volume weight is 250-290kg/m<3> and the impact strength is not lower than 2kJ/m<2>.
