Description
Technical field
The invention belongs to offset printing fountain solution technical field, be specifically related to one and exempt from alcohol edition-0 moistening liquid and preparation method thereof.
Background technology
Lithographic printing is current mainstream technology, and utilize the principle of " profit is immiscible " to implement printing, therefore fountain solution is its important printing material.Alcohol edition-0 moistening liquid is applied to lithographic printing history for many years, is added in fountain solution by alcohol (or isopropyl alcohol) and reduces surface tension, not only increase damping speed, also improve print quality.But alcohol edition-0 moistening also exists a lot of problem, as because alcohol (or isopropyl alcohol) volatilizees, fast printing machine adds cooling device, this makes, and machine construction is complicated, manufacturing cost raises; Because low the depositing in process of alcohol (or isopropyl alcohol) flash-point has disaster hidden-trouble; Because alcohol (or isopropyl alcohol) has certain toxicity, the health of harm operating personnel; Because the use of alcohol (or isopropyl alcohol) adds the discharge of VOC, be unfavorable for environmental protection.To sum up, there is many drawbacks in the use of alcohol edition-0 moistening liquid, is not suitable with the trend of green printing.What therefore research can replace the safety and environmental protection of alcohol (or isopropyl alcohol) completely exempts from the important topic that alcohol edition-0 moistening liquid is printing industry, and the exploitation of exempting from alcohol edition-0 moistening liquid has good economic benefit to printing enterprise, also adapts to the social demand of green printing.
Vehicles Collected from Market has some exempt from alcohol edition-0 moistening liquid to bring into use, but technology is also immature, such as consumption changes greatly with alcohol edition-0 moistening, operating personnel are difficult to control; Stability is not strong, changes fountain solution, cleaning bucket frequency is too high, add non-cutting time etc.
Summary of the invention
The object of the present invention is to provide one to exempt from alcohol edition-0 moistening liquid and preparation method thereof, this exempts from the object that alcohol edition-0 moistening liquid can reach safety and environmental protection, energy-saving and emission-reduction in use; In print quality, also keep the original advantage of alcohol edition-0 moistening liquid, consumption controls conveniently simultaneously.
In order to achieve the above object, the present invention exempts from mixture that alcohol edition-0 moistening liquid formed by polyethylene glycol, glycerine, potassium oxalate, natural gelatine, oleic acid diethanol amine, cocoanut fatty acid diethanolamide, alkanolamide, Sodium Benzoate, sodium sulfate of polyethenoxy ether of fatty alcohol, polyglycol ether, sodium oxalate and water the emulsification of 30-55 DEG C, wherein, by mass percentage, polyethylene glycol accounts for the 10-15% of mixture quality, glycerine accounts for the 15-25% of mixture quality, oxalic acid accounts for the 0.2-0.8% of mixture quality, natural gelatine accounts for the 5-10% of mixture quality, oleic acid diethanol amine accounts for the 0.5-2.5% of mixture quality, cocoanut fatty acid diethanolamide accounts for the 1.2-2% of mixture quality, alkanolamide accounts for the 0.2-0.5% of mixture quality, Sodium Benzoate accounts for the 0.1-0.5% of mixture quality, sodium sulfate of polyethenoxy ether of fatty alcohol accounts for the 2-5% of mixture quality, polyglycol ether accounts for the 0.2-0.5% of mixture quality, sodium oxalate accounts for the 0.8-2.5% of mixture quality, remaining in mixture is water.
The molecular weight of described polyethylene glycol is 500-1000.
The described pH value exempting from alcohol edition-0 moistening liquid is 4.5-5.5, and electrical conductivity is 800-1500 μ s/cm, and surface tension is 40-50mN/m.
A kind of preparation method exempting from alcohol edition-0 moistening liquid, water is added in reactor, and be heated to 30-55 DEG C, then at 30-55 DEG C, polyethylene glycol, glycerine, potassium oxalate, natural gelatine, oleic acid diethanol amine, cocoanut fatty acid diethanolamide, alkanolamide, Sodium Benzoate, sodium sulfate of polyethenoxy ether of fatty alcohol, polyethylene glycol and sodium oxalate is added respectively, insulated and stirred makes its emulsification, namely obtains exempting from alcohol edition-0 moistening liquid.
Compared with prior art, beneficial effect of the present invention is:
After the present invention is mixed by polyethylene glycol, glycerine, potassium oxalate, natural gelatine, oleic acid diethanol amine, cocoanut fatty acid diethanolamide, alkanolamide, Sodium Benzoate, sodium sulfate of polyethenoxy ether of fatty alcohol, polyglycol ether, sodium oxalate and water, heating emulsification forms; Wherein, oleic acid diethanol amine, the mixed liquor of the surfactants such as cocoanut fatty acid diethanolamide, alkanolamide and sodium sulfate of polyethenoxy ether of fatty alcohol is mainly used to the surface tension reducing liquid, natural gelatine can be used for increasing the viscosity of fountain solution, Sodium Benzoate is sterilizing mainly, and polyglycol ether uses as defoamer; Owing to wherein not using alcohol or these volatile and that flash-point is low materials of isopropyl alcohol, therefore, alcohol edition-0 moistening liquid can reduce to user murder by poisoning that what the present invention obtained exempt from, safety and environmental protection during use, and the discharge not having VOC, be therefore of value to energy-saving and emission-reduction.
In addition, what the present invention obtained exempt from alcohol edition-0 moistening liquid that alcohol edition-0 moistening liquid can replace current lithographic printing used completely, respond well, can be applicable on various offset press, use CTP version or PS version to complete the printing of plain paper or NCR, and improve printing product quality, reduce production cost.
