Summary: | The invention relates to perfusion polyurethane resin for a wind power blade and a preparation method thereof, and belongs to the field of composite materials of a wind power technology. The pouring polyurethane resin for the wind power blade comprises a component A and a component B which are respectively packaged and mixed during use; the component A comprises polymerized isocyanate, an isocyanate monomer and an initiator; the component B comprises polyether polyol with the functionality of 2, polyether polyol with the functionality of 3, a water removal agent, an active diluent, a defoaming agent, a polyurethane delay catalyst and an accelerant. The perfusion polyurethane resin is a two-component polyurethane system, the mixed polyurethane system has the advantages of low mixing viscosity, long gelation time, high mechanical strength and low moisture sensitivity, and a composite material product prepared from the polyurethane has the advantages of no bubble and excellent FRP (Fiber Reinforced Plastic) perf |
