Modified polyurethane/epoxy resin composite grouting cement mortar and preparation method thereof
The invention relates to modified polyurethane/epoxy resin composite grouting cement mortar and a preparation method thereof, belonging to the field of building materials. The mortar is prepared from the following components in parts by weight: 80 to 100 parts of cement, 120 to 180 parts of fine sand of 50 to 200 meshes, 20 to 50 parts of water, 4 to 7 parts of sodium silicate, 2 to 3 parts of aluminum sulfate, 1 to 2 parts of calcium chloride, 1 to 2 parts of sodium hydroxide, 10 to 15 parts of polyurethane modified epoxy resin toughening emulsion containing modified wood fiber, 1.5 to 6 parts of early strength agent and 0.9 to 2.4 parts of water reducing agent. On the basis of a modified polyurethane/epoxy resin composite material, the modified wood fiber is further compounded to facilitate the crack resistance of the grouting mortar, improve the toughness and reduce the later maintenance cost of engineering.
