Abstract
The invention discloses a preparation method of thermoplastic polyurethane for printing ink. The method comprises the following steps: adding aromatic polyester, maintaining the temperature in a range of 122-125DEG C, dehydrating at a degree of vacuum of -0.098MPa for 1-1.5h, adding a chain extender, uniformly stirring, cooling to 60DEG C, and adding 4,4'-diphenylmethane diisocyanate and C5-C8 linear paraffin; and carrying out evacuation deaeration, heating to 81-85DEG C, stopping the above reaction, taking out a material, and slaking at 135-140DEG C for 3-3.5h to obtain the thermoplastic polyurethane for printing ink. The above printing ink resin obtained by adopting the above technical scheme has the advantages of good transparency, good adhesion resistance, good bonding strength and yellowing resistance.
Description
Technical field
The invention belongs to ink manufacturing technology field, be specifically related to the preparation method of thermoplastic polyurethane for a kind of ink.
Background technology
Conventional ink is mainly solvent-borne type with polyurethane binder at present, and water color ink does not also reach solvent type ink at aspect of performance.The solvent that ink conventionally adopts benzene class or contains benzene class with tackiness agent, therefore these solvent fusing points are higher and toxicity is larger, are difficult to volatilization completely, and easily residual polluting, affects its range of application, especially to the comparatively strict packages printing field of environmental requirement.Therefore exploitation meets the imperative without benzene novel ink of environmental requirement.
Summary of the invention
Technical problem to be solved by this invention is to provide the preparation method that a kind of ink that can be dissolved in alcohol ester mixing solutions is used TPU(Thermoplastic polyurethanes), and TPU(Thermoplastic polyurethanes) has advantages of high transparent, high-adhesive-strength, resistance to xanthochromia.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the preparation method of thermoplastic polyurethane for a kind of ink, the steps include: to add aromatic polyester in reactor, keep 122～125 ℃, 1～1.5h dewaters under the vacuum tightness of-0.098MPa, then add chainextender, after stirring, be cooled to 60 ℃ of straight-chain paraffins that add 4,4 ＇-diphenylmethane diisocyanate (MDI), C5-C8; Vacuumizing and defoaming, temperature rises to 81～85 ℃, and stopped reaction takes out material 135～140 ℃ of slaking 3～3.5h.
The equal molecular mass of number of described aromatic polyester is 1300～1400.
Described chainextender is neopentyl glycol, methyl propanediol, Isosorbide-5-Nitrae-cyclohexanedimethanol.
Described chainextender accounts for 50～60% of aromatic polyester quality; Described 4,4 ＇-diphenylmethane diisocyanate accounts for 10～15% of aromatic polyester quality; The straight-chain paraffin of described C1-C4 accounts for 0.08～0.085% of aromatic polyester quality.
Beneficial effect of the present invention is: the resin for printing ink that technical solution of the present invention obtains, and the transparency and resistance to blocking are good, and bonding strength is better simultaneously, resistance to xanthochromia.
