Abstract
The invention discloses an ink for oft package intaglio printing and a preparation method thereof. The ink contains the following components in parts by weight: 20 to 25 parts of color paste, 30 to 60 parts of binder resin, 10 to 30 parts of water, 1 to 5 parts of bactericide and 1 to 5 parts of liquid wax, wherein the color paste contains the following components in parts by weight: 10 to 40 parts of water, 20 to 60 parts of water-based pigment, 1 to 5 parts of dispersant, 1 to 5 parts of defoaming agent and 10 to 30 parts of grinding-type resin. The ink causes no pollution and injury to environment and the body of an operating worker in the processes of production and use, ensures that fire accident caused by short circuit or static electricity can be avoided, has the characteristics of excellent transfer property, good color reproducibility and outstanding refreezing property, and can be used when being refrozen at normal temperature within 3 hours after being frozen; the resultant printing food package has no residual organic solvent and conforms to the demands of various countries on soft food package; the using cost is low, and the economical benefit is prominent.
Description
Technical field
The present invention relates to a kind of ink for intaglio printing and preparation technology thereof, especially relate to a kind of ink for the soft packaging intaglio printing and preparation technology thereof.
Background technology
All present, all food packaging plastic packaging gravure especially using solvent-based inks are printed on the packaging are present in the organic solvent residuals, which many kinds of organic solvents, benzene, ketones, esters, alcohols, etc., in which benzene solvent penetration in a very short time to make films for food packaging secondary pollution, causing leukemia.The printing of using printing ink to carry out soft packaging must be gone up sky with most organic solvent volatilization in the printing ink, this has not singly polluted atmosphere, also can cause grey haze weather to cause respiratory tract disease, the workman also sucks a large amount of organic solvents inevitably in printing process, thereby causes the generation of multiple occupational illness.So use the ink printing food product pack not only will rely on petroleum by-product, also can produce multiple adverse consequences strictly, and destroyed the human existence space, run in the opposite direction with environmental protection and energy saving.The production of soft packaging gravure ink just is being subjected to the restriction of numerous rules, so the green gravure ink of development and application compliance with environmental protection requirements will become inexorable trend, and the ink main developing direction that is one of them.
Ink is to be ground through the science Compound Machining by water soluble resin, pigment, water and auxiliary agent to form.Water soluble resin mainly plays binder in ink, be that granules of pigments is evenly disperseed, and makes ink have certain fluidity, and the adhesive power with the stock material is provided, and makes ink can form uniform rete after printing.Form and aspect in the ink depend primarily on pigment, and pigment is to be evenly distributed in the binder with graininess, and granules of pigments can produce absorption, reflection, refraction and transmission effect to light, therefore can present certain color.General requirement pigment has bright-coloured color and luster, appropriate colouring power and opacifying power, and higher dispersity.In addition, according to the application target difference, can also have different wear resistancies.The effect of solvent is dissolving resin, makes ink have certain fluidity, can successfully realize shifting in printing process, and viscosity and the drying property of ink are adjusted.
But still there is inapplicable high magnetic environment in ink, and the application tolerance on Frozen Food Packaging is poor, problem the such as especially reproducibility of the level effect when the high speed printing soft packaging and color is bad.And bad etc. the key of the reproducibility that solves level effect and color improves the problem of amount of pigment when being how to solve the preparation mill base, allow pigment content in the mill base behind the preparation finished product, in the time of can solving the high speed printing soft packaging from deep to shallow the intermediate color of color level and the reproducibility of shallow version color partly.
Summary of the invention
The invention provides a kind of ink for the soft packaging intaglio printing and preparation technology thereof.
Technical solution of the present invention is: a kind of ink for the soft packaging intaglio printing, and each mass component is: 20～25 parts of mill bases, 30～60 parts of binder resins, 10～30 parts in water, 1～5 part in sterilant, 1～5 part of wax liquid; The mass component of wherein said mill base is: 10～40 parts in water, 20～60 parts of water-based paints, 1～5 part of dispersion agent, 1～5 part of defoamer, 10～30 parts of grind resins.
The preparation technology of the above-mentioned ink that is used for the soft packaging intaglio printing carries out in two steps:
1) preparation of mill base: add grind resin, water successively by prescription, mix; Throw in water-based paint, dispersion agent, defoamer in the whipping process; Grind; Filter discharging;
2) preparation of look China ink: add ramming material resin, water, mill base, sterilant, wax liquid successively, mix; Filter and package.
Preferably: grind resin is that molecular-weight average is 350,000-400,000 acrylic resin.
Preferably: water-based paint is water-based pigment dyestuff and water-base inorganic pigment.
Preferably: the connectivity resin is water-based styrene-acrylic resin or aqueous acrylic emulsion.
Preferably: water-based styrene-acrylic resin or water ACRYLIC EMULSION molecular-weight average are 180,000-250,000, and second-order transition temperature is 20-25 ℃.
Preferably: sterilant is 1.2-benzisothiazole 3-ketone.
Preferably: wax liquid is that hardness is the polyethylene emulsion of 4-6.
The beneficial effects of the present invention are: the ink with water as solvent, both in production and use on the environment and operating workers not cause any pollution and damage; does not cause a fire due to static electricity or short-circuit; Metastatic gifted the Ink ; the color reproduction is good; Refreezing superior performance on the ice after three hours at room temperature within their own Refreezing can use without affecting any printing effect; resulting printed food packaging printing and because there is no residual organic solvents and conforms to the requirements of flexible packaging for food.
Embodiment
An important technology index of look China ink is the pigment content in the mill base, the determine wetting problem of when preparation mill base pigment of its crucial Zai Yu Solution, be related to printing enterprise when the high speed printing soft packaging the level effect and the reproducibility of color.Bian of the present invention grinds according to a certain percentage with grinding medium and material, grinding machinery divides the different time periods to set different rotating speeds in the process of master grind, utilize the different collision frequencies of grinding medium to reach and hold high amount of pigment, and can make it in the time of setting, finish dispersing of pigments, intaglio plate water ink print is general to use shallow version to print, it has requirement to used ink globule size, and the present invention filters ink with the filtering net of 2 μ m.
