Abstract
The invention relates to a preparation method of environmentally friendly printing ink polyurethane coupling agent. The invention is characterized in that vulcabond and polyester polyol are used to generate performed polymer with -NCO end group, then dimethylolpropionic acid and 1,4-butanediol are used to operate the chain extension reaction, finally, spasmolytol is used to adjust the pH value to neutrality, ethanol is added into the spasmolytol to be agitated, and then the printing ink polyurethane coupling agent is attained. The agglutination fastness of the coupling agent is strong, and the binding strength of the printing ink and printing backing material can be obviously promoted. The invention has the advantages that no harmful solvent exists in the processing process. The invention fully accords with the environmentally friendly technical requirements of chemical engineering accessory ingredient.
Description
Technical field
The present invention relates to a kind of preparation method of polyurethane linking agent used for environment-friendly ink, make an addition in the printing-ink, improve the fastness that combines of printing ink and printing element.Belong to chemical textile auxiliary agent technical field.
Background technology
Before the present invention made, printing ink linking agent in the past was resol, rosin modified phenolic resin, and it only has the oxidation filming function, but the attachment fastness of printing ink and printing element is not high.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of printing ink base material to be had the preparation method of the polyurethane linking agent used for environment-friendly ink of high adhesive force.
The object of the present invention is achieved like this: a kind of preparation method of polyurethane linking agent used for environment-friendly ink, it is characterized in that: earlier generate the performed polymer of end group for-NCO with vulcabond and polyester polyol, use dimethylol propionic acid and 1 then, the reaction of 4 chain expansion of succinic acid, regulate the pH value to neutrality with triethylamine at last, adding ethanol stirs, promptly obtain the printing ink polyurethane linking agent, the concrete technology of described method is: in the reaction vessel of belt stirrer, add the pure and mild vulcabond of polyester polyols, reacted 1.5 hours-2 hours down at 80-85 ℃, be cooled to 70-75 ℃, add dimethylol propionic acid (DMPA) and 1,4 butyleneglycols, insulated and stirred 30-40min, dropping accounts for the dibutyl tin dilaurate of vulcabond weight 0.08-0.12%, add the acetone that accounts for total system weight 8-12% weight percent and reduce system viscosity, 60-65 ℃ of insulation 4.5-5 hour, reduce to room temperature, add in the triethylamine and after, add ethanol, stir, slough acetone, promptly obtain the printing ink polyurethane linking agent.
Described each raw material reacts according to following proportioning:
-NCO :-OH=2.5-4: 1 mol ratio, wherein-and NCO represents isocyanate group ,-OH represents the hydroxyl of polyester polyol,
The mol ratio of dimethylol propionic acid and polyester polyol is 0.5-1.2: 1,
1, the mol ratio of 4 butyleneglycols and polyester polyol is 1.2-2.5: 1.
Described vulcabond can be IPDI, HDI, TDI or MDI.
Described polyester polyol can be poly adipate succinic acid ester or polycaprolactone.
The present invention is the molten urethane of a kind of environment protection type single-component alcohol.The bonding intensity of this linking agent is big, can obviously promote the fastness that combines of printing ink and printing element.
Polyurethane linking agent of the present invention is to be solvent with ethanol, does not have hazardous solvent in the course of processing.Can fundamentally reduce and eliminate the objectionable impurities in the coating.The environmental protection demand that meets chemical industry.
