| titleOfInvention | Oil-soluble polyurethane grouting material and preparation method thereof |
| abstract | The invention discloses an oil-soluble polyurethane grouting material and a preparation method thereof. The grouting material comprises the following raw materials: organic polyisocyanate, polyether polyol, polyester polyol, solvent, retarder, surfactant, catalyst and plasticizer; the proportion of the organic polyisocyanate, the polyether polyol and the polyester polyol is that the NCO percent of the prepolymer prepared from the organic polyisocyanate, the polyether polyol and the polyester polyol is 15 to 25 percent; the hydrophobic polyether polyol, the hydrophilic polyether polyol and the polyester polyol have the functionality of 2-4, 2-4 and 2 respectively, and the number average molecular weights of 4000-8000, 5000-8000 and 300-1000 respectively. The preparation method comprises the following steps: the polyether polyol, the polyester polyol and the organic polyisocyanate are subjected to polymerization reaction, and are stirred with a solvent, a retarder, a surfactant, a catalyst and a plasticizer. The grouting material has good toughness, can well buffer the shaking of the building cracks, and can avoid secondary water leakage. |
