Co-extrusion flame-retardant wallboard
The invention relates to the technical field of composite materials, in particular to a co-extrusion flame-retardant wallboard which comprises a wallboard body, a first connecting part arranged on one side of the wallboard body, a mounting part arranged on the other side of the wallboard body, a second connecting part arranged on the outer side of the mounting part, and a regulating part arranged between the wallboard body and the mounting part, wherein the regulating part is an inclined plane; the mounting part is positioned below the inclined plane; the wallboard body is positioned above the inclined plane; the surface of the wallboard body comprises a co-extrusion flame-retardant layer formed through a co-extrusion process. Only a flame retardant is added into the co-extrusion flame-retardant layer on the surface of the wallboard body, so that the cost of the co-extrusion flame-retardant wallboard is greatly reduced; through the co-extrusion process, the co-extrusion flame-retardant layer is directly formed on the surface of the wallboard body; due to one-step forming, the structural stability of the co-extrusion flame-retardant layer is guaranteed, secondary machining is avoided, and the production process is simplified.
