Description
Technical field
The invention discloses a kind of alcohol-free fountain solution and preparation method thereof, belong to offset printing technical field.
Background technology
At present, offset printing is still occupied an leading position in the printing industry of China.Offset printing is by printing ink transfer by printing plate
Onto rubber roll, then it is transferred to stock（Such as paper）On realize printing.It is not as letterpress and intaglio printing
Ink is directly transferred on stock by printing plate, but is transferred by rubber roll, therefore named offset printing.Offset printing is the principal mode of flat stamping.
It is the principle for utilizing " profit repels each other ", and picture and text and blank parts are constituted on same plane printing plate.Here " water " is damping
Liquid.Most of offset printing equipment is required for using fountain solution, and it is indispensable material in offset printing.Only work as damping
When liquid and ink reach ink-water balance, the true copy of original copy could be realized.
Existing fountain solution is typically by electrolyte, buffer, printing plate protective agent, wetting agent, anticorrosive, drier, life
The material composition such as thing insecticide and antifoam agent.It is roughly divided into three major types：General acidic fountain solution, alcohol edition-0 moistening liquid（Claim alcohol
Class fountain solution is more accurate）With nonionic surfactant fountain solution.Wherein, alcohol edition-0 moistening liquid is then most popular at present
Damping liquid product.
Alcohol is added in fountain solution, its surface tension can be effectively reduced, damping speed is improved, moreover it is possible to lift printing matter
Amount.But alcohol edition-0 moistening liquid, there is also many problems, mainly the use of alcohol not only increases volatility in alcohol edition-0 moistening liquid
Organic compound（VOC）Discharge, also there is inflammable and explosive potential safety hazard, simultaneously because alcohol volatilization is fast, so it is soaked
Poor-performing, damping scarce capacity, the easy water in non-graphic part is done, and is easily emulsified using rear ink, and ink setting can be produced
Harmful effect.Therefore, alcohol edition-0 moistening liquid has been not suitable with the trend of green printing.
In summary, research one kind can replace alcohol completely, and wetability and damping ability are excellent, and be difficult after to make oil
The safe environment protection type of ink emulsification exempts from the important topic that alcohol edition-0 moistening liquid is printing industry, and the exploitation for exempting from alcohol edition-0 moistening liquid is looked forward to printing
Industry has good economic benefit, is also adapted to the social demand of green printing.
The content of the invention
Present invention mainly solves technical problem：It is alcohol edition-0 moistening liquid for existing frequently-used fountain solution, there is volatilization
Property organic compound（VOC）Discharge, inflammable and explosive risk, while fountain solution wettability is poor, damping scarce capacity, non-graphic
Easily water is done for part, and is easily emulsified using rear ink, and dysgenic defect can be produced to ink setting there is provided one kind without wine
Smart fountain solution and preparation method thereof.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of alcohol-free fountain solution, is prepared from by following weight parts raw material：
8~10 parts of gelatin, 10~12 parts of methylcellulose, 5~8 parts of polyethylene glycol, 10~12 parts of lauryl sodium sulfate, 15~
20 parts of starch base Dodecyl Glucosides, 300~400 parts of hexadecanols, 500~600 parts of 1,2-PDs, 0.8~1.8 part of chlorination

~3 parts of defoamer BYK-019,4000~5000 parts of deionized waters.
The starch base Dodecyl Glucoside is after plant amylum is well mixed with ethylene glycol, then with mass fraction is 98%
Sulfuric acid solution 20~30min of stirring reaction, adds n-dodecanol, p-methyl benzenesulfonic acid, and it is anti-to be heated to 110~120 DEG C of stirrings
4~5h is answered, 70~80 DEG C is cooled to and stands after 2~3h, is that 3% sodium hydroxide solution adjusts pH to 8.0~8.5 with mass fraction,
And vacuum distillation is made.
The starch base Dodecyl Glucoside is made by following weight parts raw material：80~100 parts of plant amylums, 160~200
Part ethylene glycol, 10~12 parts of mass fractions are 98% sulfuric acid solution, 80~100 parts of n-dodecanols, and 1.8~2.0 parts to toluene sulphur
Acid.
The plant amylum is cornstarch, konjak starch, farina, sweet potato starch, acorn starch, pueraria starch
In any one.
A kind of preparation method of alcohol-free fountain solution, is concretely comprised the following steps：
S1. each component raw material is weighed by formula ratio；
S2. gelatin, methylcellulose and polyethylene glycol are added in deionized water, stirs, obtain colloidal solution；
S3. by lauryl sodium sulfate, hexadecanol and 1,2-PD 15~20min of stirring at low speed, sodium chloride, starch are added
Colloid is added after base Dodecyl Glucoside, Kathon CG sterilization antiseptic DL104 and defoamer BYK-019,20~30min of moderate-speed mixer
In solution, continue to stir 20~30min, obtain mixed liquor；
S4. disodium hydrogen phosphate, citric acid, sodium metaphosphate are taken, adds in deionized water, is stirring evenly and then adding into mixed liquor, after
30~40min of continuous stirring, obtains alcohol-free fountain solution.
Stirring at low speed speed described in step S3 is 300~500r/min, and moderate-speed mixer speed is 800~1200r/min.
The beneficial effects of the invention are as follows：
（1）Fountain solution of the present invention is answered by hexadecanol, 1,2- propane diols, lauryl sodium sulfate, starch base Dodecyl Glucoside
With alcohol is substituted, VOC emission is reduced, without inflammable and explosive equivalent risk, and gelatin, methylcellulose, polyethylene glycol enhancement is combined
The cementitiousness and wetability of solution so that fountain solution of the present invention has good wetting, permeability, can be in printing plate blank part
Uniformly sprawl, form the consistent pellicular zone of thin and thick；
（2）Fountain solution of the present invention is in printing process, by constantly being contacted with printing plate, in the electrolyte and printing plate in fountain solution
Metal chemically reactive, produce inorganic salts, make the white space for sticking to printing plate of moisture film tightly, it is periodically broken to printing plate
Bad hydrophilic layer is repaired, and forms new hydrophilic layer, and the hydrophilic layer of continuous supplementation abrasion, upper Water transport is good and not perishable
Lose it is rotten, will not emulsified ink and expand site, printing efficiency and quality are improved.
