Step once：
S1. it is first according to mass fraction calculating and takes 3-5% water-soluble dye, 15-25% organic solvent, 0.8-
1.5% trialkyl phosphates, 0.5-1.5% potassium dihydrogen phosphate, 0.2-0.4% diethylene-triamine pentaacetic acid and 70-
85% deionized water is used as the raw material of composite water soluble ink and individually placed standby；
S2. and then ready water-soluble dye and organic solvent are put into and 45-70 DEG C of temperature is heated in stirred tank
In the range of stir 10-15min, it is mixed for solvent orange 2 A；
S3. trialkyl phosphates and diethylene-triamine pentaacetic acid are added respectively into the solvent orange 2 A to have stirred, often
It must be kept stirring for when adding a kind of additive, then it is stirred for adding potassium dihydrogen phosphate after 5-10min adjusts its pH value and formed
Solvent B；
S4. deionized water is slowly filled in most backward solvent B and stirs 20-30min and obtains ink crude product；
S5. obtained ink crude product is placed in ultrasonic processing equipment and 120- is handled with 1040kHz high frequency ultrasounds
180h, then detect its indices；
S6. the ink crude product after being ultrasonically treated carries out multiple times of filtration and finally gives ink product and encapsulate guarantor
Deposit.
Further, described organic solvent is the mixture of glycerine and tetrahydrofuran, glycerine and tetrahydrofuran it is mixed
Composition and division in a proportion is 4：3.
Further, in step sl with mass fraction than 4：3 take glycerine and tetrahydrofuran is put into stirred tank and carried out
Mixing 10-15min makes it mix to obtain organic solvent and deposited standby.
Further, the step S6 is comprised the following steps that：
S61. filter plant is ready to first, the filter plant includes standing pond, multi-layer filter paper filter and poly- four
PVF filter cloth filtering machine；
S62. the ink crude product after being ultrasonically treated, which is passed through to stand, carries out cooling and standings precipitation in pond, during standing
A length of 30-50min；
S63. and then by the ink crude product stood in pond multi-bed filter and polytetrafluoroethylene (PTFE) filter-cloth filtering are passed through successively
Filtered in machine, by the small particle contaminant filter in ink crude product；
S64. the ink product most come out at last from polytetrafluoroethylene (PTFE) filter cloth filtering machine is stored in macromolecule storage barrel
Row storage.
Further, 5-7 layer polypropylene cotton filter layers, the polytetrafluoroethylene (PTFE) filter-cloth filtering are provided with the multi-bed filter
3-5 strata tetrafluoroethene filter clothes are provided with machine.
Ink has a variety of sorting techniques, wherein can be divided into water-based and organic solvent type according to type of solvent, and it is of the invention
It is a kind of water-based ink-jet printing ink, then its dyestuff used adds ionized water as solvent for water-soluble dye, appropriate to increase
Some organic solvents are added to improve compatible degree, and described organic solvent is a kind of hydrophilic organic solvent, can be dissolved in water
In.Requirement of the ink-jet printing ink on print performance mainly has:Image clearly, color are true to nature, have well water-fast, fast light
