Mixing 15min, add remaining raw material after being cooled to room temperature, stirring is to being completely dissolved, after filtration and get final product.
The preparation method of described UV offset printing fountain solution, it is characterised in that comprise the following steps:
(1) weigh raw material by formula, in reactor, add water, by boric acid, stearoyl diethanolamine, carboxymethyl chitosan
Sugar, aluminium sesquioxide, 3-hydroxy-2-butanone, pentyl acetate put in reactor, are heated to 60-80 DEG C, stir 10-15min;
(2) temperature is adjusted to 50-60 DEG C, add carbomer, aloe, nano silicon, inositol hexaphosphate, to hydroxyl
Ethyl benzoate and auxiliary agent stir 15-30min under the conditions of 600-800rpm;
(3) being cooled to room temperature, add rest materials, stirring is to dissolving completely, and filtering and impurity removing matter gets product.
The invention have the advantage that
1. it is applicable to UV offset printing, ink emulsification can be controlled, keep ink-water balance, reach good printing effect.
2. there are preferable soda acid buffering and water resistant ability, water quality range width.
3. the usage amount of ink and water reduces, and is dried faster, and the service life of forme is longer, is suitable for various different application
Environment.
Detailed description of the invention
Non-limiting examples of the present invention is as follows:
The preparation of fountain solution
A kind of UV offset printing fountain solution, is prepared from by the component raw material of following weight (kg): carbomer 4, stearoyl diethyl
Hydramine 5, carboxymethyl chitosan 4, boric acid 3, aluminium sesquioxide 2,3-hydroxy-2-butanone 1, potassium iodate 2, pentyl acetate 1.5, Aloe
Oil 2, salicylic acid 2, inositol hexaphosphate 4, nano silicon 1, aethyl parabenum 3, auxiliary agent 8, water 40;
Wherein, auxiliary agent is made up of the raw material of following weight (kg): glycerol 7, Polyethylene Glycol 6, glycine 1, citric acid 2, oil
Acid 1.5, Oleum Caryophylli 0.5, rhamnose 0.5, tea polyphenols 0.5, sodium bicarbonate 2, sodium citrate 18, Tween 80 3, water 40;First by lemon
Lemon acid, sodium citrate are dissolved in water, are heated to 50-60 DEG C, add glycerol, Polyethylene Glycol, Oleum Caryophylli, oleic acid and sodium bicarbonate,
Stirring 15min, adds remaining raw material after being cooled to room temperature, stirring is to being completely dissolved, after filtration and get final product.
Its preparation method comprises the following steps:

The performance of fountain solution
Printability and printing effect are had a significant impact by the emulsifying of UV offset ink, therefore control water-pickup of ink and are closing
In the range of reason to improve printing quality significant.According to offset printing principle, in offset printing process, water-pickup of ink less than 26% is
Feasible.
The mensuration of water-pickup of ink C: use gravimetric method.
By described fountain solution distilled water diluting to 3%, the most once add 50g UV offset ink and 50g dilution
After fountain solution, stand 10min after 100r/min stirring 1h, remove residual moisture, weigh the weight of residual ink, by following public
Formula calculating water-pickup of ink:
Measurement result water-pickup of ink is 18.50%, within normal range, meets the requirement of print production.
