| titleOfInvention | Preparation method of modified polyurethane used for printing ink |
| abstract | The invention discloses a preparation method of a modified polyurethane used for printing ink. The preparation method comprises following steps: (1) by weight, adding 10 to 30 portions of a monomer and 40 to 70 portions of a solvent into a reaction vessel, wherein the monomer is composed by diisocyanate and a polyol with a mole ratio of 1:1; keeping stirring and heating the mixture to 50 to 80 DEG C, and then keeping the temperature for 4 to 8h; adding 0.1 to 2 portions of a neutralizer for neutralization so as to obtain a polyurethane prepolymer solution; and (2) by weight, dispersing 0.5 to 3 portions of a nano material in 20 to 30 portions of the solvent, adding the mixture into a reaction vessel; keeping stirring, heating the mixture to 60 to 90 DEG C and reacting for 6 to 10h so as to obtain an emulsion of the modified polyurethane and obtain the modified polyurethane after removing the solvent. The modified polyurethane of the invention is used for printing ink, and is used as a resin in link materials; and is capable of increasing the glueyness of the printing ink on the surface of printing substrates, improving thermal stability of the printing ink, and shortening curing time greatly. |
