Description
Technical field
The present invention relates to a kind of ink and manufacture craft, especially relate to a kind of the isostructural improvement of ink-jet printing ink and preparation method thereof.
Background technology
Along with the continuous development of computer technology and numeral science and technology, ink-jet printer is more and more accepted by users as a kind of extremely useful output equipment, and popularity rate also day by day improves, and makes family and office work more be tending towards convenient, efficient, standard.At present the main flow on the ink-jet market is a type of dye ink, and it has characteristics such as beautiful in colour, reduction ratio height, but its relatively poor waterproof and fast light ability make its application be subjected to certain limitation.Chinese patent discloses a kind of ink-jet printing black ink and preparation method thereof (Granted publication number: CN 1184269C), its recipe ingredient is by weight: 5~15 parts of mixing colouring agents, 8~50 parts of dye carriers, 0.1~0.5 part of 0.1~5 part of auxiliary agent of tensio-active agent, 55~80 parts of deionized waters, mixing colouring agent is a dye mixture, dye carrier is one or more in polyvalent alcohol, polyoxyethylene glycol, polyvalent alcohol monoalky lether or the water-soluble heteroato mic organic compound, wherein polyvalent alcohol is a glycol ether, triglycol, glycerine; The polyvalent alcohol monoalky lether is an ethylene glycol monobutyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, triethylene glycol monomethyl ether; The polyoxyethylene glycol of molecular weight 200~400; Water-soluble heteroato mic organic compound is diethanolamine, trolamine, N-Methyl pyrrolidone, dihydroxyethylsulfide, tetramethylene sulfone, methane amide; Tensio-active agent is selected from the anion surfactant of soap, alkylbenzene sulfonate, alkyl-sulphate or alkylphosphonic; Perhaps one or more in the nonionogenic tenside of alkyl alcohol Soxylat A 25-7, alkylphenol polyoxyethylene, polyox-yethylene-polyoxypropylene block copolymer or glycerin polyoxyethylene ether; Auxiliary agent is selected from one or more of disodium ethylene diamine tetraacetate, tetrasodium ethylenediamine tetraacetate, vitamins C or 5-chloro-2-methyl-4-isothiazoline-3-ketone; Its preparation method: with mixing colouring agent 5~15 weight parts and deionized water 10~60 weight parts, adding has in the mixing kettle of agitator and thermometer, mixes 20~30 minutes in 70~80 ℃ of temperature; With dye carrier 8~50 weight parts, tensio-active agent 0.1~0.5 weight part, auxiliary agent 0.1~0.5 weight part, add in another mixing kettle that has agitator, after mixing into transparent liquid under the room temperature, join in the above-mentioned aqueous solution, mixed 20~30 minutes, add balance of deionized water 20~45 weight parts, be cooled to room temperature, discharging under stirring.But this ink and preparation method only are applicable to the production black ink, and the production of inapplicable color inks, and the ink specific conductivity of producing and viscosity are all higher, can cause the phenomenon of disconnected China ink during use.
Summary of the invention
The purpose of this invention is to provide a kind of ink-jet printing ink and preparation method thereof, it mainly is that existing ink of solution existing in prior technology and preparation method only are applicable to the production black ink, and the problem of the production of inapplicable color inks; It is all higher that the present invention has also solved ink specific conductivity and the viscosity produced, can cause the technical problem of the phenomenon etc. of disconnected China ink during use.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
