Abstract
The invention discloses a method for preparing a heat-insulating and flame-retardant polyurethane foaming material for a building exterior wall. The method comprises the steps of quickly mixing a mixed solution A, a component B and a component C at the room temperature of 20 DEG C until the mixture becomes white, immediately injecting the mixture into a mold cavity of a pre-prepared mold with the mold temperature of 30 DEG C, carrying out foaming molding, keeping for 6 hours, then, cooling to room temperature, opening the mold, taking foam out of the mold cavity, and standing for a week at room temperature, thereby obtaining the heat-insulating and flame-retardant polyurethane foaming material for the building exterior wall. The polyurethane foaming material has flame-retarding and heat-insulating properties and is extensively applied to heat insulating layers of building exterior walls.
