Key technologies of fireproofing and insulation system for polyurethane foam and moulding board with glazed-hollow-bead

To improve the poor performance in fire prevention and adhesiveness of external insulation system of polystyrene board, the new insulation system of polyurethane foam and moulding board with glazed-hollow-bead mortar is designed. According to the principle of the temperature gradient and the spreading and releasing stress in different layers, the fire prevention and aging resistance performance of polystyrene board in external insulation system is improved. Performances of fireproofing and insulation motor of different ingredients, such as glazed hollow bead, fly ash, polymer emulsion powder, quicklime, fiber, were tested in the lab and the reasonable mix ratio of the mortar was obtained. Moulding board of glazed-hollow-bead mortar was deigned and manufactured. To quickly construct and improve quality of the new insulation system, fixed moulding board system was manufactured.
