| description | The invention belongs to the technical field of carbon emission reduction and polyurethane material preparation, and particularly discloses rigid non-isocyanate polyurethane foam and a preparation method thereof. The preparation method comprises the following steps: reacting a rigid epoxy compound with CO2 to obtain rigid cyclic carbonate, then reacting the product with diamine to obtain rigid non-isocyanate polyurethane, and mixing the rigid non-isocyanate polyurethane with a foaming agent for foaming to obtain the rigid non-isocyanate polyurethane foam. According to the invention, the structure and groups of the raw materials are limited, so that the mechanical property and adjustability of the non-isocyanate polyurethane are improved; the reaction degree is obviously enhanced and an excellent foaming effect is achieved by adopting normal pressure, low temperature and other mild reaction conditions and adjusting the dosage of reactants and the foaming agent.
