| description | The invention relates to the technical field of building materials, and discloses high-strength gypsum mortar and a preparation method thereof. The gypsum mortar is prepared from the following raw materials in parts by weight: 60 to 70 parts of gypsum powder, 20 to 30 parts of modified polyurethane, 5 to 8 parts of glass fiber, 5 to 8 parts of diatomite, 7 to 10 parts of mica powder, 2 to 4 parts of a water reducing agent, 1 to 2 parts of a retarder, 0.5 to 1 part of a thickening agent, 10 to 15 parts of Portland cement, 0.5 to 1 part of rubber powder and 70 to 90 parts of deionized water. The modified polyurethane is added, so that the strength, cohesiveness and water resistance of a matrix are improved; the glass fiber is added, so that the mechanical property of the matrix is improved; the hardness and the strength of the matrix are improved by adding the mica powder; other auxiliary agents are added and have a synergistic effect, so that the overall performance of the matrix is improved; therefore, the gy |
