Description
Technical field
The present invention relates to the preparation method that a kind of safe environment protection type exempts from alcohol edition-0 moistening liquid, belongs to and exempt from alcohol edition-0 moistening liquid technology neck
Domain.
Background technique
Fountain solution is indispensable a kind of chemical assistant in color press printing process, its effect is the blank in printing plate
Part forms uniform moisture film, to prevent the ink of areas from infiltrating to blank parts, prevents dirty version, while can also supplement
The hydrophilic layer lost in printing process, and space of a whole page temperature can be reduced, it can be seen that, fountain solution is a kind of extremely important printing
Material.
Lithographic printing is current mainstream technology, utilizes the principle of " grease is immiscible " to implement printing, therefore fountain solution is
Its important printing material.Alcohol edition-0 moistening liquid is applied to the history that lithographic printing has had many years, and alcohol (or isopropanol) is added
Being added in fountain solution reduces surface tension, not only increases damping speed, also improves print quality.But alcohol edition-0 moistening
There are many problems, such as fast printing machine of alcohol (or isopropanol) volatilization increases cooling device, this makes, and machine construction is complicated, manufactures
Cost increases；There is fire hazard during the low storage of alcohol (or isopropanol) flash-point；Alcohol (or isopropanol) has certain toxicity,
Endanger the health of operator；The use of alcohol (or isopropanol) increases the discharge of volatile organic compounds, is unfavorable for ring
It protects；And traditional alcohol fountain solution easily generates corrosion to metal position, influences printing quality.To sum up, the use of alcohol edition-0 moistening liquid is deposited
In many drawbacks, it is not suitable with the trend of green printing.Therefore research can replace the safety and environmental protection of alcohol (or isopropanol) completely
Exempt from the important topic that alcohol edition-0 moistening liquid is printing industry, exempting from the exploitation of alcohol edition-0 moistening liquid has good economic imitate to printing enterprise
Benefit also adapts to the social demand of green printing.
Summary of the invention
The present invention solves the technical problem of: all contain a large amount of ethyl alcohol or isopropyl substantially for traditional fountain solution
Alcohol prints a large amount of volatilizations in workshop and influences workers ' health, and generates corrosion to metal parts, while isopropanol emission is to ring
Border generates dysgenic defect, and providing a kind of amino acid surfactant and polyethylene glycol cooperation reduces surface tension, then
With cetyl trimethylammonium bromide cooperate increase wettability, then with lanolin and calcium gluconate cooperation offer it is anticorrosive at
Part prepares the method that safe environment protection type exempts from alcohol edition-0 moistening liquid, and the present invention is hydrolyzed in acid condition using albumen powder, obtains amino
Acid, then lauric acid is reacted with thionyl chloride and generates lauroyl chloride, then amino acid is reacted with lauroyl chloride using Xiao Dunbaoman
N- lauroyl amino acid surfactant is prepared, amino acid surfactant has good wetability, and catabolite is
Amino acid and fatty acid on environment without influence, then with lanolin, Arabic gum etc. are mixed to get damping base fluid, Arabic gum tool
There is good amphipathic property, fountain solution stability can be improved, increases the wetability to printing plate, it is finally mixed with citric acid etc. again
It closes, safe environment protection type can be obtained and exempt from alcohol edition-0 moistening liquid, lanolin and calcium gluconate cooperation can form one layer in metal surface
Protective film prevents from corroding, and alcohol edition-0 moistening liquid produced by the present invention of exempting from does not add alcohols material, is free of volatile noxious material,
Environmental protection completely, it is harmless, have the function of very strong microbiocidal, can control and prevent micro- life of damping working solution
Object pollution, prevents metal parts to be corroded, protects the damage of printing plate and printing machine not by earlier water.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
(1) weigh 50~60g albumen powder be added to fill 400~500mL mass fraction be 10% hydrochloric acid flask in, and
