| description | The invention discloses a synthetic method of water-based polyurethane resin for water-based ink, and relates to the field of industrial paints. The technical scheme includes the following steps: 1, aselecting an organic diisocyanate compound to react with a high-molecular dihydric alcohol compound with carboxyl, wherein the organic diisocyanate compound is hydrogenated toluene diisocynate, the macromolecular dihydric alcohol compound is polycarbonate dihydric alcohol, an N-methyl pyrrolidone solution needs to be added into the hydrogenated toluene diisocynate in the reaction, and stirring is performed at the temperature of 80 DEG C; 2, cooling a product generated by the reaction, and adding a neutralizer and a solvent into the product to neutralize so as to generate a PU prepolymer; 5%-10% of high-hardness water-based PU resin is added in the production process, so that the high-temperature resistance of the subsequently produced ink is high, the phenomenon that a spray head is blocked in an environment with |
