| titleOfInvention | Polyurethane grouting material, preparation method and application |
| abstract | The invention relates to a polyurethane grouting material, a preparation method and application thereof, and discloses a polyurethane compound for grouting, a preparation method and application thereof, wherein the polyurethane compound consists of A, B components, and the component A comprises the following components: polyether polyol, amine-based polyol, epoxy resin, a foaming agent, a toughening agent, a phase change material, a reactive diluent, a compatilizer and a retarder; the component B is polyisocyanate. The polyurethane grouting material has the characteristics of good toughness, excellent bonding effect, cooling property, self-catalysis and oleophylic and hydrophilic grouting, can be suitable for repairing defects such as voids, cracks and slurry pumping of road surface base layers of highway tunnels and bridge engineering butt straps, voids and subsidence of bridge engineering butt straps, and can also be used for waterproof treatment, maintenance and reinforcement of water conservancy and electric power facilities, mineral resource exploitation, underground and underwater building engineering and fault emergency repair treatment of water leakage and water permeability. |
