Abstract
The invention discloses a method for preparing a pure water urethane resin and reverse printing ink. The pure water urethane resin is prepared by the following steps of: dehydrating polyester polyol and polyether polyol with molecular weight of between 1,500 and 3,500; reacting the polyester polyol and the polyether polyol with polyisocyanate; and adding copolymer of vinyl chloride and hydroxy-ethyl acrylate into the reaction product and performing polymerization. The synthesis process of the resin is simple; and the ink prepared from the resin has the advantages of high adhesion, high wettability, high dispersion, high adhesion, bright color, high drying speed and no residue on a printed matter. The resin and the ink have wide application range and can be used for plastic thin films such as PET, PVC, BOPP, OPP and the like.
Description
One, technical field
Pure-water polyurethane resin and reverse printing ink are exactly the preparation method of a kind of pure-water polyurethane resin and reverse printing ink specifically.
Two, background technology
The solvent-borne type inner-printing ink is at print line widespread use already.Because itself has the existence of toluene, dimethylbenzene, butanone equal solvent, it just pollutes the environment, it is healthy to endanger people.Particularly food product pack country has force and has forbidden not allowing with hazardous solvents such as toluene, butanone.At present, the printing circle also has the molten and molten printing ink of ester of some alcohol, though do not contain deleterious toluene, it remains based on solvent, and itself is just inflammable and explosive, dangerous, and static is met in printing can cause incalculable financial loss.
Three, summary of the invention
In order to solve above-mentioned deficiency, the preparation method of a kind of pure-water polyurethane resin and reverse printing ink, adopted the pure and mild polyether glycol dehydration of the polyester polyols back of molecular weight 1500-3500 to form with the copolymer polymerization that the polyisocyanates reaction adds vinylchlorid and Hydroxyethyl acrylate again, its solid content is 30%.Replace all solvents with pure water.Disperse, grind, be packaged into ink after the synthetic pure-water polyurethane resin added pure water, auxiliary agent and pigment dyestuff proportioning more in proportion.
Adopt the technology of the present invention, improved production environment, guaranteed that the workman's is healthy.Improve product percent of pass, improved production efficiency, reduced cost, obtained client's favorable comment, possessed the market competitiveness.
Four, embodiment
Below in conjunction with embodiment the present invention is described in further detail.
With polyester polyol 10-50 and the polyether glycol 30-80 dehydration back and polyisocyanates 20-60 of molecular weight 1500-3500, vinylchlorid 0.5-3, Hydroxyethyl acrylate 1-5 reactive polymeric forms, and the reaction back adds pure water 60-70, and the generation solid content is 30% pure-water polyurethane resin.After disperseing with pure-water polyurethane resin 20-50, adding pure water 50-80, adding auxiliary agent 1-10, adding pigment dyestuff 10-30 again, grind and be packaged into ink.
Claims (3)
