The foaming properties of polyurethane rigid foam were studied by using different hydroxyl value, functionality, viscosity of polyether polyols, polyisocyanates, water, catalyst, foam stabilizer and crosslinking agent as raw materials. The microstructure and macroscopic morphology of the foams were analyzed by scanning electron microscope (SEM), which provided the basis for the selection and optimization of the composition of the raw materials for the preparation of polyurethane rigid foam. The effects of polyether polyols, catalysts, water, isocyanate index, foam stabilizer and other factors on the properties of polyurethane foam plastics were emphatically analyzed. Based on this, a high-performance all water foaming rigid polyurethane foam formula was determined.
