When using this urethane resin to make printing-ink, suitably add various pigment, solvent, use common printing ink producing apparatuss such as dispersion machine, sand mill again, just can make printing compound oil ink of the present invention by dispersion, grinding etc.In addition, beyond the urethane resin as matrix resin of the present invention, as required can also be with resin as follows as the additional material that connects, for example soluble cotton, vinyl chloride-vinyl acetate copolymer, rosin based resin etc.
Below specify the preparation of urethane resin of the present invention with example:
(1) in having 2 liters of four-hole boiling flasks of agitator, thermometer, reflux condensing tube and rare gas element ingress pipe, the number-average molecular weight of packing into is 1000 modification polycaprolactone glycol 257g, and butanone 200g evenly stirs.
(2) in above-mentioned polyhydric alcohol solutions, add isophorone diisocyanate 1.9g and as the catalyzer two lauric acid dioctyl tin 0.08g of urethane esterification, in 80 ℃ of reactions 4 hours, obtain to contain two and terminally be the polyurethane prepolymer of isocyanate group.
(3) in polyurethane prepolymer solution, add butanone 500g, behind the ethyl acetate 420g uniform mixing, add the mixing solutions of Virahol 280g, isophorone diamine 42g and Monoethanolamine MEA BASF 2g again, react until isocyanate group in 40 ℃ and to disappear, obtain urethane resin, add an amount of acetic acid ethyl ester at last it is diluted to 30% solid content.
Urethane resin viscosity by the said process preparation is that 3000CP (25 ℃), number-average molecular weight are 21000.
The urethane compound oil ink has two kinds of the benzene of containing type and benzene-free types.Benzene-free type uses the non-aromatic kind solvent, as butanone, vinyl acetic monomer, n-propyl acetate, Virahol, n-propyl alcohol etc.Urethane resin of the present invention in building-up process by to the adjustment of its microtexture, thereby do not need to use toluene when making its dissolving, and be to use butanone, Virahol as dissolution with solvents.Wherein butanone is true solvent, and Virahol is a solubility promoter, and it is better to the dissolving meeting of urethane resin that both mix use, and toluene does not have any effect to dissolving resin, does not need to add.In addition, for the consideration of aspects such as production cost and drying and volatilizing speed, can adopt vinyl acetic monomer, two kinds of solvents of n-propyl acetate to be used to substitute toluene.Need in the printing ink use just can use to certain viscosity with solvent cut, do not need to use toluene in the thinner equally, can adopt proportioning be butanone 40%, n-propyl acetate 40%, Virahol be 20% or butanone 50%, vinyl acetic monomer 30%, n-propyl alcohol be that 20% mixed solvent dilutes.
