The average molecular mass of PTMG is 1500-2500, and degree of functionality is 1.5-3.2.Poly-tetrahydrochysene
Furan ether glycol is preferably the PTEMG2000 that Beyer Co., Ltd produces.
The relative molecular mass of polyether polyol is 500-1500, and degree of functionality is 1.5-2.5.Polyether polyol is preferably moral
The DDL-700 that the federal chemical Industrial Co., Ltd of letter produces.
Isocyanates is isophorone diisocyanate (IPDI).
The preparation method of aqueous printing ink polyurethane of the present invention, comprises the following steps:
(1) lower the temperature after polyether polyol and PTMG being mixed intensification vacuum dehydration；
(2) add isocyanates temperature reaction, add dimethylolpropionic acid stirring reaction, obtain prepolymer, cooling；
(3) add BDO stirring reaction, be cooled to room temperature, obtain performed polymer；
(4) take performed polymer, add acetone, stir, drip triethylamine, add defoamer, deionized water, ethylenediamine,
Emulsifying, boils off all acetone, obtains product.
As the preferred technical scheme of one, the preparation method of aqueous printing ink polyurethane of the present invention, including with
Lower step:
(1) polyether polyol and PTMG are put in reaction bulb, be warming up to 100.0-120.0 DEG C, very
Empty dehydration 1.8-2.2 hour, is cooled to less than 40 DEG C；
(2) add isocyanates, be warming up to 80.0-85 DEG C, react 1.5-2 hour, be cooled to 63-67 DEG C, add dihydroxy
Methylbutanoic acid, under the conditions of controlling temperature 80-85 DEG C, stirring reaction 1.5-2.0 hour, obtain prepolymer, be cooled to 60-65 DEG C；
(3) add BDO, under the conditions of controlling temperature 80-85 DEG C, after stirring is reacted 1.5-2.0 hour, be cooled to
Room temperature, obtains performed polymer；
(4) take performed polymer, add acetone, stir；Dropping triethylamine, time for adding is 1-2 hour, is stirred for 2-3
Hour；Add defoamer, deionized water, ethylenediamine, emulsifying 90-150min in high shear force mulser, obtain the poly-ammonia of aqueous
Ester solution, utilizes Rotary Evaporators 30-40 DEG C of decompression distillation, boils off all acetone, i.e. can get finished product.
Wherein:
In step (2), the NCO mass fraction of prepolymer is 0.5-3%.
Emulsifying temperature described in step (4) is 15-25 DEG C.
In sum, the invention have the advantages that
(1) product of the present invention is water-based emulsion, uses process harmless to environment and human body.
(2) product solid content up to more than 50% of the present invention, it is simple to using, after making ink according to formula, paper is attached
The property is good, and drying time is fast, it is to avoid ink printed paper, water-fast, rub resistance.
(3) product of the present invention is used to have excellent wear-resisting, water resistance after making ink.
