Detailed description of the invention
Fig. 1 is fluid present invention e-inks accepting medium structural schematic diagram.
Each label indicates in figure are as follows: 1- support, 2- liquid electronic ink-receiver layer.
Specific embodiment
Liquid electronic ink receptor medium provided by the invention, the oil including support and on support one or both sides
Black receiving layer.The ink-receiver layer is composed of the following parts by weight: (a) 30 parts~60 parts of inorganic particle, (b) is bonded
30 parts~65 parts of agent, (c) 0.03 part~10 parts of curing agent.
The inorganic particle is that cation modifier was modified to obtain inorganic particle, and the ZETA current potential of dispersion liquid is+10mv
~+40mv.
It is polypropylene amine, diethylenetriamines, dipropylenetriamine, Sanya second that cation modifier of the present invention, which is selected from,
One or more of urotropine.
The parts by weight of inorganic particle of the present invention are 30 parts~60 parts, and image, which otherwise can occur, to be shifted completely
Problem, or even de- print can be led to the problem of.
Inorganic particle of the present invention is selected from silica, the aluminium oxide, zinc oxide, carbonic acid that diameter is 0.01 μm~1 μm
One or more of calcium, china clay, barium sulfate etc..Other property such as shape, specific surface area and porosity for inorganic particle
It can be not particularly limited.The diameter of inorganic particle is less than 0.01 μm, and manufacturing process is complicated, higher cost；Inorganic particle it is straight
Diameter is greater than 1 μm of glossiness that will affect liquid electronic ink receptor medium surface.
The ZETA current potential of cationic inorganic particle dispersion of the present invention is+10mv~+40mv.If cationic inorganic
The ZETA current potential of particle dispersion is lower than+10mv, and cationic inorganic particle dispersion is unstable, and the ink-receiver layer of preparation is led
Electrically insufficient, resistance to print property is deteriorated；If the ZETA current potential of cationic inorganic particle dispersion is higher than+40mv, it is technically difficult to
It realizes, and the production cost is very high.
Adhesive of the present invention be selected from water-soluble resin, binary or polynary water-dispersion type copolymer emulsion one of or
It is several.Water-soluble resin is selected from polyvinyl alcohol, polyvinylpyrrolidone, gelatin, starch or starch conversion object, hydroxy ethyl fiber
One or more of element, methylcellulose, polyethylene oxide improve the adhesive force of ink-receiver layer and support.
The preferred polyvinyl alcohol of invention adhesives, wherein the polyvinyl alcohol degree of polymerization is 1700~4000, degree of hydrolysis 50%
~99%.If the pectin/polyvinyl alcohol degree of polymerization is lower than 1700, ink-receiver layer is low with the adhesion strength of support, will cause in printing
Ink-receiver layer falls off, and influences printing performance；If the pectin/polyvinyl alcohol degree of polymerization is higher than 4000, ink-receiver layer and support it is attached
Put forth effort height, but production technology is complicated, it is at high cost.If the degree of hydrolysis of pectin/polyvinyl alcohol is lower than 50%, ink-receiver layer waterproofness
Difference；If the degree of hydrolysis of pectin/polyvinyl alcohol is higher than 99%, technically it is difficult to reach.
The more preferable water-soluble cationic resins of invention adhesives selected from cationized polyvinyl alcohol, cationic starch, gather
One or more of aziridine, allyl amine, diallyl alkyl polymer improve cationic inorganic particle and bonding
The compatibility of agent, increases the adhesiveness of ink-receiver layer and liquid electronic ink, while improving image conservation rate.
Binary of the present invention or polynary water-dispersion type copolymer emulsion are selected from ethylene and acrylate copolymer emulsion, ethylene and vinegar
One or more of sour ethylene copolymerization emulsions, alkene acrylate copolymer emulsion, polyurethane copolymerization lotion, copolymerization of butylbenzene lotion, two
The addition of first or polynary water-dispersion type copolymer emulsion improves ink-receiver layer and prints the waterproofness of image.It is of the present invention
Binary or the glass transition temperature of polynary water-dispersion type copolymer emulsion are 35 DEG C~160 DEG C, if its glass transition temperature is lower than 35 DEG C,
It is easy to cause ink-receiver layer softening during production and working stock to deform or even generate adhesion problems, if glass
Change temperature and be higher than 160 DEG C, ink-receiver layer brittleness is big, easily leads to the problem of printing quality.
Binary of the present invention or polynary water-dispersion type copolymer emulsion by least one hydrophilic monomer X, at least one is non-
Hydrophilic monomer Y and other units Z is formed, and wherein X:Y:Z is 1~3:8~6:0~3.The number ratio Tai Gao or too low of X:Y:Z
The low problem with waterproofness difference of ink-receiver layer adhesive force will all be will cause, and then keep image conservation rate low, printing image anti-
Aqueous difference.
Binder wt number of the present invention is at 30 parts~65 parts.If the parts by weight of adhesive are lower than 30, influence
Inorganic particle causes it in continuous printing since the friction between liquid electronic ink receptor medium is made the adhesiveness of support
With causing part inorganic particle to fall off from liquid electronic ink receptor medium, be deposited on blanket, influence subsequent printing
Quality is also easy to produce the disadvantage of white point, and not can be carried out high-volume presswork.If the parts by weight of adhesive are higher than 65,
Adhesion problems are also easy to produce, or even paper jam problem occurs.
Curing agent of the present invention be selected from one of formaldehyde, glyoxal, boric acid, borax, polyisocyanate, aziridine or
It is several.It is to improve its waterproofness that curing agent is added in ink-receiver layer.The additional amount of curing agent at 0.03 part~10 parts, Gu
Agent additional amount is lower than 0.03 part, and ink-receiver layer waterproofness is poor；Curing agent additional amount is higher than 10 parts, leads to liquid electronic ink
The printing of accepting medium is poor, i.e., resistance to print property is insufficient.
After ink-receiver layer of the present invention is dry with a thickness of 0.1 μm~3 μm, if ink-receiver layer thickness is less than
0.1 μm, painting process is complicated, is easy to produce de- painting disadvantage；If ink-receiver layer thickness is greater than 3 μm, except production improves cost
Outside, ink-receiver layer may crack disadvantage in the drying process.
In the paper base, plastic-coated paper-based, PET, TAC, PVC, PE, PC, PNT that support of the present invention is 50 μm~500 μm
One kind.If less than 50 μm, easily there is the problem of tearing, part in coating process in the thickness of support；If support
Thickness be greater than 500 μm, the liquid electronic ink receptor medium of preparation is too thick, printing when easily occur transmission it is unsmooth, even
Paper jam problem can occur.When support is paper base, asbestos base paper, plain paper, drawing paper, stamp paper, art paper, blank can be selected
One of paper, carbon paper, printing paper, glassine paper etc..In addition, support can also be by Corona discharge Treatment, plasma at
The surface treatments such as reason improve the coating of ink-receiver layer.
