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 and preparation technology thereof who is used for intaglio printing, especially relate to a kind of ink and preparation technology thereof who is used for the soft packaging intaglio printing.
Background technology
The at present all food product pack particularly plastic wrapping of intaglio printing all are to adopt the solvent type ink printing, on packing material, all there is organic solvent residual, these residual organic solvent kinds are many, benzene, ketone, ester, alcohol etc. are arranged, wherein benzene kind solvent can penetrate film and makes food in the packing be subjected to Er to dye in very short time, thereby causes leukemia etc.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 a part to connect in ink to expect, is to make the granules of pigments homodisperse, 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 graininess to connect in the material, 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 a dissolving resin, makes ink have certain fluidity, can successfully realize shifting in printing process, and the 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 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 and preparation technology thereof who is used for the soft packaging intaglio printing.
Technical solution of the present invention is: a kind of ink that is used for the soft packaging intaglio printing, and each mass component is: 20～25 parts of mill bases connect 30～60 parts of material 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, and 000, second-order transition temperature is 20-25 ℃.
Preferably: sterilant is a 1.2-benzisothiazole 3-ketone.
Preferably: wax liquid is that hardness is the polyethylene emulsion of 4-6.
The invention has the beneficial effects as follows:this ink is solvent with water, no matter produce with use in all can not Cheng and dye and damage environment and operator's health Zao; Can not cause fire because of static or short circuit; This ink transitivity is excellent; Colorrendering quality is good; Freeze superior performance again, after freezing, be placed on to freeze again voluntarily in 3 hours under the normal temperature and just can use and do not influence any printing effect; Gained prints on the food packaging article without any residual organic solvent meets the requirement of various countries to food flexible packing because print.
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.
