Description
Technical field
The present invention relates to fountain solution fields, and in particular to a kind of green alcohol-free fountain solution.
Background technique
Offset printing be using grease is miscible, solid is to the two natural laws of the selective absorption of liquid,
The picture and text replicated and blank parts are established jointly in the unified plate surface Jing Guo technical treatment, there are blank parts very
Strong water absorbing properties, areas oleophylic water repellent.In printing process, first supplies water to entire printing plate, make the blank parts of the space of a whole page
It adsorbs water and forms water membrane, then, then give printing plate ink supply.At this point, due to printing plate blank parts oneself there are water membrane, oil
Ink cannot be adsorbed in blank parts, areas water repellent oleophylic and adsorb one layer of ink.Therefore, the work in offset printing of fountain solution
With very important.
In the fountain solution of hectographic printing, the effect of alcohol or isopropanol is mainly: first is that reducing the dynamic table of fountain solution
Face tension makes fountain solution become more " wet " so that it is unfolded in the non-graphic regional diffusion of printing plate；Second is that increasing fountain solution
Viscosity；Third is that fountain solution is promoted to carry out necessary appropriate emulsification to offset ink；Fourth is that by the volatilization of alcohol or isopropanol,
Heat caused by high speed printing is taken away, is cooled down to printing element；Fifth is that alcohol can carry out disinfection to fountain solution.But it uses
The problem of alcohol or isopropanol, 40% all volatilizations of alcohol or isopropanol slatterned in fountain solution it is clear that first is that volatilization is fast；
Second is that alcohol or isopropanol are somewhat expensive；Third is that inflammable and explosive；Fourth is that isopropanol toxicity is higher, generally isopropanol content is required to be lower than
400ppm, but be often significantly more than this standard in machine room.
Nowadays, printery is all making great efforts to create environmental printing and is reducing printing cost, they wish in printing process
Without using industrial alcohol or isopropanol, because these products seriously pollute environment and price is also constantly soaring.However, exempting from wine
Smart fountain solution cannot arbitrarily be applied on printing machine, it is necessary to be exchanged, and carried out to machine thin closely with press operator
Cause adjustment.Alcohol technique is exempted from introducing, and there are two crucial adjustment points: first is that dynamic surface tension, it is necessary to which alcohol edition-0 moistening is exempted from adjustment meticulously
For the dynamic surface tension of liquid to 30-35dynes/cm, performance characteristic when with using isopropanol printing is identical；Second is that viscosity, nothing
When alcohol or isopropanol print, viscosity is reduced so that fountain solution becomes thinner, and unjustified dampening system cannot be fully
Fountain solution is supplied on printing plate, ink-water balance, which is broken, will cause adverse consequences.
Chinese patent " CN105383203B " discloses a kind of alcohol-free environment-friendly type fountain solution and preparation method thereof, this
Fountain solution includes following components and parts by weight content: 70-85 parts of deionized water, 2-5 parts of pH adjusting agent, 10-25 parts of aqueous colloidal
And 0.5-2 parts of nonionic surfactant, this fountain solution property is stablized, and safety and environmental protection, alcohol-free and printing adaptability is good, adds
The nonionic surfactant added can effectively adjust the surface tension of fountain solution, and preparation process is simple, and controllability is good, be suitable for industry
Metaplasia produces.But the numerical value of this fountain solution and indefinite Ph and conductivity, press resistance rate are to be improved.
Summary of the invention
The purpose of the present invention is to provide a kind of greens to exempt from alcohol edition-0 moistening liquid, and this fountain solution is in parameter and containing industrial wine
The being consistent property of fountain solution of essence, press resistance rate is high, and ingredient is environmentally protective in formula.In order to realize that above scheme, the present invention provide
Following technical scheme:
A kind of green exempts from alcohol edition-0 moistening liquid, and fountain solution is by mass percentage by following material composition: cellulose 3%-4%；
Citric acid 1%-2%；Sodium citrate 2%-3%；Surfactant 30%-35%；Glycerol 25%-30%；Preservative 2%-
2.5%；Diethylene glycol (DEG) 5%-8%；Aqueous defoamer 2%-5%；Pure water surplus.
Preferably, fountain solution is by mass percentage by following material composition: cellulose 3%；Citric acid 1%；Sodium citrate
3%；Surfactant 35%；Glycerol 25%；Preservative 2%；Diethylene glycol (DEG) 5%；Aqueous defoamer 4%；Pure water 22%.
Preferably, it includes 2,4,7,9- tetramethyl -5- decine -4 or 7- glycol polyoxy that surfactant, which is surfactant,
Ethylene ethers.
Preferably, preservative is one or more of potassium sorbate, dehydroactic acid sodium and sodium benzoate.
Preferably, aqueous defoamer is the fatty acid ester compounded object of higher alcohols.
Green exempts from the preparation method of alcohol edition-0 moistening liquid the following steps are included: first that cellulose dissolution is uniform, sequentially adds
Citric acid, sodium citrate, surfactant, glycerol, diethylene glycol (DEG), aqueous defoamer, preservative, pure water, which stirs evenly, to be obtained
Obtain fountain solution.
The utility model has the advantages that
1, it is 4.8-5.5 that green of the present invention, which exempts from alcohol edition-0 moistening liquid Ph value range, and conductivity range 900-1200 μ s/cm makes
Exempt from alcohol edition-0 moistening liquid with green of the present invention, so that press resistance rate improves.
2, green of the present invention exempts from alcohol edition-0 moistening formula of liquid environment-friendly and green, ensure that the safety of operator.
3, exempting from alcohol edition-0 moistening liquid using green of the present invention will not cause environment to influence in workshop, and machine mill is greatly reduced
Damage, while suitable Ph value and conductivity are made printing is greatly reduced after being exempted from alcohol edition-0 moistening liquid using green of the present invention and dust
