Abstract: The present invention features that the water base block polyurethane is prepared with component A as soft phase block prepolymer and component B as hard phase block prepolymer through further reaction in water. The component A is prepared with catalyst, polyether or polyester diol, aromatic or fatty diisocyanate, and chain expander short-chain fatty diol in certain proportion; and the component B is prepared with aromatic diisocyanate, cross-linking agent trihydroxyl polyol, chain expander short-chain fatty diol, hydroxyl radical containing short-chain fatty diol and neutralizer short-chain fatty organic butyl amine in certain proportion. The present invention also provides waterproof, heat insulating and moisture permeating material with the polyurethane.
