One kind of high solid cationic waterborne polyurethane resin was synthesized after neutmlization and dispersion with water after the reactions with the polyester diols(PE-l 000), non-ionic polyether diol YmerTMN120, 1,6-hexanediol(HDO), castor oil polyolsl(C.O.), MDEA and Toluene diisocyanate(TDI). The cationic waterborne polyurethane resin waterborne wood sealer was made by the prepared resin, defoamers, leveling agents, wetting and dispersing agents, thickeners. The properties of resin were characterized by Fourier transform infrared spectroscopy(FT-IR), thermal gravimetric analyzer(TGA), particle size analyzer, and various coating testing equipment. The results indicated that when using PE-1000 and nonionic polyether diol YmerTMN120 mixed as the polyer diol, in a ratio between the 1/5 to 1/4 range, the molecular weight of the prepolyer from 3 500 to 5 000, the total amount of MDEA from 10% to 12%, the content of HDO from 6% to 7%, the prepared high solid cationic waterborne polyurethane resin had good water and alcohol resistance. Moreover, the CWPU waterborne wood sealer had better performances.
