| titleOfInvention | A kind of preparation method of environment-friendly extinction type waterborne polyurethane resin |
| abstract | The present invention is an environment-friendly preparation method of extinction type water-based polyurethane resin. The polyurethane prepolymer is first prepared. Use polyethylene glycol to react with aliphatic diisocyanate, such as isophorone diisocyanate or hexamethylene diisocyanate, and then add carboxylic acid type hydrophilic chain extender and polyether type polyol in turn to prepare water-based polyurethane prepolymer. body. The second step is the water dispersion and post-chain extension process. The deionized water is added to the water-based polyurethane prepolymer for dispersion, the post-chain extender 2-[(2-aminoethyl)amino]sodium ethanesulfonate aqueous solution and the hydrazine hydrate aqueous solution are successively added dropwise, and finally a kind of environment is prepared. Friendly matt waterborne polyurethane resin. The advantage of the invention is that a matting type waterborne polyurethane resin is prepared by a chemical matting method, the preparation process is simple, and no organic solvent or matting agent is needed. This type of resin emulsion has good stability, high solid content, good mechanical properties of the film, good water resistance, gloss (60°) <2.0, light transmittance (%) <11, and solid content 45-50%. |
