The invention provides high-solid-content water-based polyether type polyurethane resin, which is prepared from the following raw materials in parts by weight: 100 to 150 parts of polyhydric alcohol,20 to 40 parts of polyisocyanates, 4 to 8 parts of first chain extenders, 3 to 5 parts of second chain extenders, 3 to 6 parts of triethylamine, 0.05 to 0.1 part of organic bismuth catalysts and 120 to 140 parts of water. The polyhydric alcohol and the polyisocyanates are weighed according to the part number; reaction is performed for 2 to 3h at 85 to 95 DEG C; then, the first chain extenders andacetone are added; reaction is performed for 1 to 3h at 75 to 85 DEG C; then, the organic bismuth catalysts are added; reaction is performed for 2 to 3h at 65 to 75 DEG C; the temperature is lowered to 35 to 45 DEG C; then, the triethylamine is added and is stirred; after the water is added, continuous stirring is performed; then, the second chain extenders are added; then, reactants react for 2 to 3h at 30 to 60 DEG C; the acetone is removed in a vacuum way; the high-solid-content water-based polyether type polyurethane resin can be obtained. The solid content of the polyurethane resin can reach 60 percent or higher; good elasticity, excellent damp heat resistant performance, higher peeling strength and excellent hydrolytic resistant performance are realized; the polyurethane resin is particularly suitable for a weaving coating.
