Description
Technical field
The present invention relates to adhesive for printing ink, particularly relate to and a kind of plastics film is had good attachment fastness, color developing, anti-ly returns sticking gravure composite printing ink with the preparation method of urethane resin.
Background technology
The gravure ink of at present press use is generally made by Chlorinated Polypropylene III.In the Printing ink producing process, Chlorinated Polypropylene III need to use strong solvent (such as aromatic solvents such as toluene) to dissolve, and also needs to regulate with toluene the viscosity of printing ink in printing process.Now, the Chlorinated Polypropylene III ink system is considered to non-environmentfriendly products.Because the Chlorofluorocarbons (CFCs) that it volatilizes aborning can be destroyed atmospheric ozone layer; In Printing ink producing and printing process, the use meeting of the aromatic solvents such as toluene produces injury to workman's health and safety.In addition, the aromatic solvents such as toluene are the slow curing solvents, very easily remain in the dried China ink layer, can pollute the packing content thing and produce peculiar smell.Polyurethanes printing ink is compared with Chlorinated Polypropylene III, has the following advantages: 1. polyurethane ink adopts alcohol, esters solvent, need not to rely on benzene kind solvent; 2. the stripping strength of polyurethane ink and base material is far above the Chlorinated Polypropylene III class, as the stripping strength of Chlorinated Polypropylene III on NY only have 1-2N/15mm, and polyurethane ink can reach 2-5/15mm; 3. polyurethane ink can be regulated ink performance such as drying property, sticking power, viscosity etc. by regulating material combination, proportion of composing, reaches good balance, realizes excellent printability; 4. with respect to chlorinated polymer, it is extensive that urethane is used base material, and the former generally can only be used for the gravure of BOPP, and the latter can be common to the base materials such as PET, NY, BOPP, PE.
CN1696217A mentions a kind of urethane resin that obtains by the following method: at first prepare through isocyanate-terminated prepolymer, then diamines is added in the diluent of prepolymer and carry out chain extension, carry out end-blocking with monoamine at last, described urethane resin is for the preparation of printing ink composition.CN101168633A discloses a kind of urethane resin that dissolves in ethanol, and preparation end NCO base performed polymer adds butyleneglycol and carries out chain extension in the performed polymer first, and the course of processing meets environmental requirement without hazardous solvent.CN1972977A discloses the preparation method of Polyurethane Resins for Inks, and wherein said urethane resin adopts polycaprolactone and isocyanate reaction, adds the diamines chain extension again and is prepared.
The shortcoming of above-mentioned urethane is, their preparation method adopts " one still process " to be prepared, be that NCO is excessive in the performed polymer, then in same reactor, diamines added in the performed polymer contain NCO and carry out chain extension, because NCO and amino speed of response are very fast, after adding diamine chain stretching agent, the diamines partial concn is too high, causes the interior local molecular weight of system very large, and molecular weight distribution is irregular, resin viscosity is wayward, simultaneously, the chain extension process is owing to being the excessive state of NCO all the time in the system, and the urethane resin that finally obtains very easily contains completely NCO group of unreacted, after being long placed in, these NCO groups can slowly react, cause the molecular resin amount to continue to increase, viscosity changes, and brings potential safety hazard to use, and the molecular resin chain end group that aforesaid method synthesizes is NCO base or alkyl, be the low-pole group, the ink adhesion that causes this resin to get is generally relatively poor, easily returns sticking, color developing is poor, and combined strength bination is little.
