Sound-insulation and heat-preservation light wallboard with double layers or multiple layers of different media

The invention belongs to the technical field of fabricated building wallboards, and particularly relates to a sound-insulation and heat-preservation light wallboard with double layers or multiple layers of different media. The sound-insulation and heat-preservation light wallboard comprises a wallboard body. The wallboard body comprises an outer side light aggregate layer, a steel wire framework and a middle layer. The middle layer is fixed into the steel wire framework and comprises at least two sound-insulation and heat-preservation layers, and the light aggregate layer is arranged between the adjacent sound-insulation and heat-preservation layers. The middle layer and the steel wire framework are wrapped with the outer side light aggregate layer. The light aggregate layer, the outer side light aggregate layer and the at least two sound-insulation and heat-preservation layers are compounded, the sound-insulation effect of the wallboard body is effectively enhanced, and the sound-insulation performance of th
