A kind of water soluble acrylic acid printing-ink with fixation waterproof efficacy
Technical field
The present invention relates to printing-ink field, be specifically related to a kind of water soluble acrylic acid printing-ink with fixation waterproof efficacy.
Background technology
Printing-ink is a kind of common printed matter coloured material, and forming primarily of compositions such as pigment, low-melting ink vehicle, stopping composition, is the pulpous state adherent that a class is coloured, have certain degree of mobilization.Want to obtain gratifying printing effect, to the color of ink in actual use procedure, printing adaptability, rate of drying has certain requirement, also to possess water-fast according to environment for use simultaneously, fast light, acid and alkali-resistance, the features such as low toxic and environment-friendly, following printing-ink developing direction must be towards low toxicity, quick-drying, the future development of the naturally various and multifunction of color, but the inadequate environmental protection of existing ink ubiquity, viscosity controls uneven, not good and partial properties good ink such as to hold at high price at the shortcoming with base material sticking power, therefore, the composition and engineering of necessary improvement printing-ink, the transition of quickening industry, to reach the production model of high-efficiency environment friendly.
Summary of the invention
The object of the invention is to, provide a kind of water soluble acrylic acid printing-ink with fixation waterproof efficacy, improve its printing performance, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of water soluble acrylic acid printing-ink with fixation waterproof efficacy, it is characterized in that, this ink is made up of the raw material of following weight part: iron nitrate 0.2-0.3, anhydrous sodium sulphate 1-2, aluminum oxide 6-8, nano-silicon 3-5, water soluble acrylic resin 25-30, gelatin 5-8, isocaprylic acid bismuth 0.4-0.5, water-based paint 10-12, deionized water 20-25, auxiliary agent 2-4;
The raw material of following weight part is comprised: carbomer 3-5, trolamine 1-2, nano-stannic oxide 2-3, emulsifier op-10 4-5, ferric acetyl acetonade 0.1-0.2, dehydrated alcohol 20-25, N.F,USP MANNITOL 4-5 in described auxiliary agent, preparation method is: first add in dehydrated alcohol by carbomer, trolamine, after dispersed with stirring 40-50min, add nano-stannic oxide, ferric acetyl acetonade again, mixture ball milling 1-2h after stirring, add other remaining component subsequently, continue dispersion 40-50min, to obtain final product.
Described a kind of water soluble acrylic acid printing-ink with fixation waterproof efficacy, its preparation method is as follows:
(1) first iron nitrate, anhydrous sodium sulphate mixed dissolution are scattered in deionized water, then drop into water-based paint, dispersed with stirring evenly grinds 1-2h afterwards, and gained material is for subsequent use;
(2) step (1) gained material is mixed with other remaining component, drop in homogenizer, after the rotating speed dispersed with stirring 60-80min of 1200-1500 rev/min, again compound is dropped into ball-milling processing in ball mill, the particle diameter of gained slurry is made to be 10-20 μm, and adjusting viscosity as required, to obtain final product.
Water color ink advantage prepared by the present invention is: the principle that first have followed low toxic and environment-friendly in the preparation of raw material, using water as solvent medium, improve the feature of environmental protection, and water-based paint is dropped into iron nitrate, in anhydrous sodium sulphate mixing solutions, to improve the consistency of itself and resin emulsion, improve the stability of pigment, strengthen the defensive ability/resistance ability of its environment to external world, combining nano silicon again, gelatin, isocaprylic acid bismuth, the booster action of the raw materials such as auxiliary agent, water-borne acrylic resin ink prepared by the present invention has good rate of drying, slurry viscosity is controlled, thixotropy is good, efficiently quick during printing, printing effect is evenly clear, bright color is lasting, waterproof and dampproof, easy to clean, the market competitiveness is strong.
Embodiment
Embodiment
Printing-ink prepared by the present embodiment is made up of the raw material of following weight part: iron nitrate 0.2, anhydrous sodium sulphate 1, aluminum oxide 8, nano-silicon 3, water soluble acrylic resin 30, gelatin 8, isocaprylic acid bismuth 0.4, water-based paint 12, deionized water 25, auxiliary agent 4; Wherein auxiliary agent is made up of the raw material of following weight part: carbomer 4, trolamine 2, nano-stannic oxide 3, emulsifier op-10 5, ferric acetyl acetonade 0.1, dehydrated alcohol 25, N.F,USP MANNITOL 5, preparation method is: first add in dehydrated alcohol by carbomer, trolamine, after dispersed with stirring 50min, add nano-stannic oxide, ferric acetyl acetonade again, mixture ball milling 1.5h after stirring, add other remaining component subsequently, continue dispersion 50min, to obtain final product.
The preparation method of this printing-ink is as follows:
(1) first iron nitrate, anhydrous sodium sulphate mixed dissolution are scattered in deionized water, then drop into water-based paint, dispersed with stirring evenly grinds 2h afterwards, and gained material is for subsequent use;
(2) step (1) gained material is mixed with other remaining component, drop in homogenizer, after the rotating speed dispersed with stirring 60min of 1500 revs/min, then compound is dropped into ball-milling processing in ball mill, the particle diameter making gained slurry is 10 μm, after adjusting viscosity and get final product.
