Abstract
The invention relates to a wringing process for producing offset printing fuchsine ink. The process comprises the following steps that: firstly, hydrous fuchsine paint, wet pulp causticize calcium, a bonding material and a water resisting agent which are not dried are put to a kneading machine and kneaded till water is clear; secondly, moisture is extracted under the conditions of vacuum and high-temperature; thirdly, a based ink obtained is rolled on a three-roller machine for once or twice; fourthly, ink oil and an addition agent are added and the oil is adjusted to a preset index scope; finally, the ink is filled and packaged by a racking machine. The ink made by the wringing process of the invention is more exquisite than the ink made of dry powder, has larger colour density, good transparence, high luster, strong tinctorial strength and good emulsification resistance and can save man-hour.
Description
Technical field
The present invention relates to a kind of manufacturing process of offset printing magenta ink, the filter cake that just is to use aqueous pigment dyestuff specifically is through the water squeezing method, and the technology that replaces water with oil is made manufacture of ink.
Background technology
In the existing flexographic ink production technique pigment that adopts dry-powdered.
For example, a kind of weight proportion of existing fuchsin flexographic ink can for:
Connect material 50-70%;
Cochineal 13-20%;
Ink oil 5-15%; And
Auxiliary agent 5-15%.
What cochineal wherein adopted is dry-powdered pigment, and its production technique comprises the steps:
1. in mixer, add pigment, connect material, part ink oil;
2. with rotating speed 500-1000RPM, stirred 40-60 minute
3. will stir sufficient material and get into the three-roller grinding, pressure: 30-60Mpa, temperature: the 50-70 degree, through three grindings, the fineness of printing ink is controlled at below 10 μ;
4. add remaining ink oil and auxiliary agent, printing ink is adjusted in the set quota scope;
5. carry out can with filling machine.
The problem that should have technology now is, because pigment adopts dry powder, so printing ink production is long man-hour, and the fineness of printing ink, gloss, transparency and depth of shade are not good.
Summary of the invention
The object of the present invention is to provide a kind of printing ink manufacturing process, to overcome the defective that existing technology man-hour is long, ink quality is not high.
For reaching above-mentioned purpose, the present invention adopts water squeezing technology, and wherein this printing ink comprises cochineal; Wet pulp causticization calcium; Connect material; Ink oil; And auxiliary agent, it is characterized in that this production technique may further comprise the steps:
In kneader, drop into moisture cochineal, wet pulp causticization calcium, connection material and water repellent agent, pinch to water clear without oven dry;
Under the vacuum high-temperature condition, extract moisture out;
With the Ji Mo that obtains on three-roller rolling 1-2 time;
Add ink oil and auxiliary agent, printing ink is adjusted in the set quota scope; And
Filling machine carries out can.
Preferably, the vacuum high-temperature condition of above-mentioned extraction moisture is temperature: 60-120 ℃; Time: 1-4 hour; And vacuum tightness is: 0.5-1MPa.
Preferably, above-mentioned basic China ink is at pressure: 30-60MPa, temperature: be rolled under the condition of 50-70 degree.
Because the present invention directly processes the aqueous pigment filter cake, need not to carry out drying operation, so on the whole practiced thrift man-hour.
Following table has disclosed the comparative parameter that printing ink that the printing ink that technology is processed according to the present invention and existing dry powder technique process carries out.
Table one: measure result's (pigment is given money as a gift under the same condition of content)
| ? | The present invention | Existing dry powder technique |
| Fineness | The 2-3 level | The 3-4 level |
| Depth of shade | 105％ | 100％ |
| Transparency | Transparent | Standard |
| Gloss | 75 | 65 |
| Water-intake rate | 32 | 40 |
| Produce man-hour | 1-2 hour/100 kilograms | 2-3 hour/100 kilograms |
Fineness numerical value in the last table is more little, shows that the sophistication of printing ink is better.
The water-intake rate numerical value of printing ink is more little good more in the last table, shows that the printing ink suction is few, and the emulsification possibility is little.
The technology that the present invention adopted makes pigment can keep the dispersion state of single particle; Therefore the comparison through last table; Under the identical condition of the content of giving money as a gift; The printing ink that the printing ink of processing with water squeezing technology is made than dry powder is finer and smoother, depth of shade is bigger, transparency is good, gloss is high, strong coloring force, resistance to emulsification are good, and can practice thrift man-hour.
Embodiment
The present invention is a kind of water-expelling production process for offset printing magenta printing ink, the weight proportion of this printing ink can for:
Cochineal 40-60%;
Wet pulp causticization calcium 5-15%;
Connect material 30-50%;
Ink oil 5-15%; And
Auxiliary agent 5-15%.
This water squeezing production technique comprises the steps:
A. in kneader, drop into moisture cochineal, connection material and water repellent agent, pinch to water clear without oven dry;
B. under the vacuum high-temperature condition, extract moisture out;
C. with the Ji Mo that obtains on three-roller rolling 1-2 time;
D. add ink oil and auxiliary agent, printing ink is adjusted in the predetermined indication range; And
E. carry out can with filling machine.
Above-mentioned moisture cochineal without oven dry can contain the pigment slurry of certain moisture without oven dry.
In a preferred embodiment, among the above-mentioned steps b, the vacuum high-temperature condition of extracting moisture out is temperature: 60-120 ℃; Time: 1-4 hour; And vacuum tightness is: 0.5-1MPa.
In a preferred embodiment, among the above-mentioned steps c, Ji Mo is at pressure: 30-60MPa, temperature: be rolled under the condition of 50-70 degree.
