Low-odor quick-dry ink and preparation method thereof

The invention relates to low-odor quick-dry ink and a preparation method thereof, and belongs to the technical field of printing ink. The prepared ink is prepared from the organic silicon modified polyurethane emulsion, the rosin phenolic resin, the modified acrylic emulsion, the auxiliaries and the pigment, hydrophilic groups are introduced in the synthesis process of polyurethane in the ink, and the water resistance and adhesive force of the ink can be improved through cooperation of the hydrophilic groups and the modified acrylic emulsion; the auxiliary agent can improve the dispersity of the pigment and reduce the viscosity of the ink, so that the printing quality is improved; according to the invention, the siloxane is subjected to hydrolytic condensation in the film forming process to form a Si-O-Si cross-linked network, so that the thermal stability and water resistance of the ink are further improved; according to the invention, organic silicon is introduced into the polyurethane emulsion for modifica
