The invention discloses a method for synthesizing 1,1-diamino-2,2-dinitroethylene. The method comprises the steps as follows: sulfuric acid is added to a reaction flask firstly, nitric acid is then added dropwise, and mixed nitric-sulfuric acid is prepared; 2-methyl-4,6-pyrimidinedione or 2-methyl-4,6-hydroxypyrimidine is added to the mixed nitric-sulfuric acid in batch, filtering is performed after reaction, a nitrating acid filtrate is collected, a filter cake is added to ice water, filtering and drying are performed, and 1,1-diamino-2,2-dinitroethylene is obtained; fuming sulfuric acid withmass fraction of 50% and nitric acid with mass fraction of 98% are added to the collected nitrating acid filtrate in proportion sequentially, and the prepared mixed nitric-sulfuric acid can be recycled directly. The method is used for synthesizing 1,1-diamino-2,2-dinitroethylene.
