Abstract
The invention relates to an ink solvent, in particular to a green offset ink solvent. The offset ink solvent produced from monoacid of waste vegetable oil is polyalcohol monoester of the monoacid of the waste vegetable oil, which is generated by esterification of monoacid of the waste vegetable oil and polyalcohol in the presence of a catalyst; and accounted by percentage of total weight of the monoacid of the waste vegetable oil and the polyalcohol, the monoacid of the waste vegetable oil is 70 to 90 percent and the polyalcohol is 10 to 30 percent. Greasy ester compounds are used for the offset ink, so that the offset ink has good dilution and printability; and the greasy ester compounds can make the offset ink with macromolecular resin and organic pigment, the offset ink has good green safety and good printability, and is suitable for offset presses with high speed or low speed. The ink has no harm to environment and human bodies in the using process, is a green product absolutely, and has substantial market potential.
Description
Technical field
The present invention relates to printing ink solvent, relate in particular to a kind of offset printing ink solvent of green type.
Background technology
At present, because green requirement increases severely day by day, the primary solvent mineral oil of flexographic ink, because natural Dioxins exists, more and more be subjected to the green query and the restriction of use range in the mineral oil, Xian Jin flexographic ink producer all comes substitute mineral oil at the product of studying with soybean wet goods vegetables oil abroad, therefore, the numerous and confused soybean oil type offset printing printing ink of releasing, its purpose is used the vegetable oil products substitute mineral oil exactly, not only helps green health but also help the social resources reprocessing cycle.
The domestic large-scale producer of vegetables oil polyamide resin, the annual use vegetables oil in a large number that need, annual consumption is greatly about about 10,000 liang of kilotons, produce ton surplus vegetable oil type product and the vegetable oil derivatives 10,000 per year, in the production process because polymeric ununiformity polymer has 5% tripolymer, 30% not polymerisable unit acid, 65% dimer after finishing.Because the acid of vegetables oil unit is unfavorable for the polymerization chain extending reaction of polymeric amide next stage, therefore, the acid of vegetables oil unit must be extracted with the distillatory mode, abandon as by product.The annual therefore depleted vegetables oil unit acid of factory reaches more than 2,000 ton.
Summary of the invention
For the technological deficiency that the primary solvent mineral oil that solves existing flexographic ink exists, the purpose of this invention is to provide a kind of offset printing ink solvent of green type.Further, the present invention has also solved the application of vegetables oil polyamide resin by product vegetables oil unit acid.
In order to realize above-mentioned purpose, the present invention has adopted following technical scheme:
The offset printing ink solvent that the acid of waste vegetable oil unit is produced, this solvent is a waste vegetable oil list acid polyol monoesters, waste vegetable oil list acid polyol monoesters carries out esterification by acid of waste vegetable oil unit and polyvalent alcohol and generates in the presence of catalyzer, by the described waste vegetable oil of the per-cent unit acid of acid of waste vegetable oil list and polyvalent alcohol gross weight be 70～90%, polyvalent alcohol is 10～30%.As preferably, the usage quantity of above-mentioned catalyzer is acid of waste vegetable oil unit and 1～2% of polyvalent alcohol gross weight.
As preferably, above-mentioned waste vegetable oil unit acid is selected from the waste vegetable oil unit acid by product of vegetable oil type polyamide resin in producing.Certainly, waste vegetable oil of the present invention unit acid should be not limited to the waste vegetable oil unit acid by product in the production of vegetable oil type polyamide resin, all can be suitable for for the acid by product of the waste vegetable oil unit in other production of resins.
As preferably, above-mentioned polyvalent alcohol is selected from contract in four propylene glycol, glycerine, TriMethylolPropane(TMP), tetramethylolmethane, dipentaerythritol, polyether Glycols, polyether-tribasic alcohol, polyethers tetravalent alcohol, polyethers pentavalent alcohol, Xylitol, sorbyl alcohol, the N.F,USP MANNITOL one or more of ethylene glycol, neopentyl glycol, propylene glycol, glycol ether, triglycol, Tetraglycol 99, dipropylene glycol, tripropylene glycol, three.
Product of the present invention remove have nontoxic, have no irritating odor, non-corrosiveness, do not fire, outside not quick-fried, the characteristics such as safety in utilization good, concentration is high, printing adaptability is good, especially have the good and good characteristics of resistance to emulsion of solvability.
An other purpose of the present invention provides the preparation method of the offset printing ink solvent of above-mentioned waste vegetable oil unit acid production, this method drops into the acid of waste vegetable oil unit, polyvalent alcohol, catalyzer in the reactor earlier according to quantity, be warming up to 210 ℃～230 ℃, protected 30～75 minutes, look into acid number, treat acid number≤2 back cooling discharges.
The present invention is owing to adopted above technical scheme, the butyrous ester compound is used in and makes flexographic ink have good dilution and printability in the flexographic ink, can make flexographic ink with macromolecule resin and pigment dyestuff, this printing ink not only green safety is good, and printability is good, is fit to different high speed or low speed offset printing presses.And in use there is not harm in printing ink to the environment and the person, definitely is green green product, and its market potential is very considerable.Adopt product of the present invention to replace mineral oil in traditional flexographic ink, the technology thinking was identical when its printing ink was produced, and operational path is more simple, and purpose is identical and meaning is more extensive, not only helped green health but also help the social resources reprocessing cycle.
