Polymer repairing mortar for rapidly repairing pavement and preparation method thereof

The invention relates to the technical field of pavement repair, and discloses polymer repair mortar for quickly repairing a pavement, which comprises the following raw materials in parts by weight: 100-200 parts of cement; 300 to 500 parts of sand; 1-10 parts of a water reducing agent; 25 to 100 parts of resin; 5-20 parts of a curing agent; 1 to 20 parts of fatty alcohol-polyoxyethylene ether; 50 to 150 parts of sodium carbonate; 20 to 100 parts of butyl acrylate; 1 to 10 parts of a diluent; the resin adopts polymer resin, and the polymer resin is formed by copolymerizing an N-substituted maleimide monomer, an acrylic ester monomer which does not contain a five-membered ring lactone structure and an acrylic ester monomer which contains a five-membered ring lactone structure. The resin, the curing agent, the diluent and the accelerant are added for compression resistance, so that the prepared polymer repair mortar has relatively high tensile strength, breaking strength and compressive strength, and the bondin
