Abstract: A high-resilience PU spring sponge and a preparing method thereof are provided. The high-resilience PU spring sponge includes a sponge main body and high-strength springs. A top portion of the sponge main body defines a sponge top surface. First grooves are defined on the sponge top surface. A bottom portion of the sponge main body defines a sponge bottom surface. Second grooves are uniformly defined on the sponge bottom surface. The preparing method includes a mold preheating and mold pretreatment step, a material mixing pretreatment step, a slurry introducing step, a slurry foaming curing and demolding step, and a natural curing and finished product processing step. The second grooves are defined on the sponge main body after the sponge main body is cured and the second grooves are formed through the perforated columns. Each of the first grooves is communicated with a corresponding second groove.
