Preparation process of rock wool polyurethane compound insulation board for external thermal insulation of exterior wall
The invention discloses a preparation process of a rock wool polyurethane compound insulation board for external thermal insulation of an exterior wall. According to the process, a finished product rock wool board (1) is conveyed into a gumming machine (3) by use of a roller conveyor (2); a roller capable of rotating continuously is matched in the gumming machine; a flame retardant adhesive (4) is put into the gumming machine; when the finished product rock wool board passes through the gumming machine (3), the lower surface of the finished product rock wool board can be gummed; the gummed rock wool board (5) is transported to a polyurethane board continuous production line (6), and finally, the rock wool polyurethane compound insulation board (7) for external thermal insulation of the exterior wall can be produced by virtue of the steps of casting (6-1), foaming (6-2), curing (6-3) and cutting (6-4). The process has the advantages that the previous production process only capable of producing the polyurethane boards is changed into the production process for producing rock wool and polyurethane compound insulation boards, and the produced rock wool polyurethane compound insulation board for external thermal insulation of the exterior wall has integrated properties of safety, fire resistance, energy conservation and thermal insulation.
