Abstract
The invention is a water-soluble printing ink washing agent and the making technique. It firstly adds softened water to mixing jar and heats to 35-45 deg.C, adds polyoxyethylene octane phenolic ether or polyoxyethylene nonylphenol, 3-5% and trihydroxy ehhylamine, 2-6%, to the mixing jar, fully stirs for 15-30 minutes, then adds butyl fibre-dissolving agent, 3-9%, to the mixed solution, stirs for 20-30 minutes to mix evenly, and then uses thin hydrochloric acid, 2%, to adjust the pH of the washing agent to 7-8. The washing efficiency is high and the application range is wide.
Description
Technical field
The present invention relates to a kind of clean-out system that is used for printing-inks such as cleaning printing press tool, forme, rubber roll, blanket, be specially water soluble ink scavenger prescription and preparation technology.
Background technology
Be used for the cleaning printing press tool in the Printing industry, forme, rubber roll, the printing ink at inking positions such as blanket, use kerosene mostly, gasoline, alcohol, acetone, organic solvents such as ethyl acetate are made clean-out system, such clean-out system has inflammable, explosive, contaminate environment, be detrimental to health, can cause dissolving to the material surface that is cleaned, swelling, corrosion, loss of gloss, cracking or foaming equivalent damage or defective, and cleaning performance is unsatisfactory, being cleaned the surface, position often leaves floating dirty, year in and year out, the China ink dirt that can find some position accumulation of the frequent inking of machine is understood more and more thicker.People have developed water soluble ink scavenger on this basis, " a kind of water soluble ink scavenger prescription and preparation technology " patent application was disclosed March 14 calendar year 2001 as Patent Office of the People's Republic of China, publication number is: 1287142, and this technical scheme adopts components such as monobutyl ether, Virahol, coconut oil, ethanol, soda ash, tripoly phosphate sodium STPP, oxalic acid, deionized water to be prepared into water soluble ink scavenger.Along with the continuous appearance of water soluble ink scavenger, we have also found the drawback of this type of clean-out system: the scope of application that has is narrow, as cleaning rubber roll; The injury skin that has; The corroding metal that has; The performance gentleness that has but cleaning performance is not good enough, workman's wash machine defensive position stick printing ink and are difficult to clean, and impact that board prints and waste of manpower, and have prescription, complex manufacturing technology, drawbacks such as tooling cost height.
Summary of the invention
The purpose of this invention is to provide a kind of with low cost, prescription, the simple water-solubility printing ink washing agent of manufacture craft and preparation technology thereof.
Water-solubility printing ink washing agent main component of the present invention comprises: polyoxyethylene octyl phenolic ether or polyoxyethylene nonylphenol ether, trolamine, ethylene glycol butyl ether (that is, ethylene glycol monobutyl ether) and softening water, and the weight percent of its each component is as follows:
Polyoxyethylene octyl phenolic ether or polyoxyethylene nonylphenol ether 3～5%
Trolamine 2～6%
Ethylene glycol butyl ether 3～9%
All the other are softening water.
This water-solubility printing ink washing agent preparation technology is:
A. in mixing tank, add softening water, be heated to 35～45 ℃;
B. with adding mixing tank after polyoxyethylene octyl phenolic ether or polyoxyethylene nonylphenol ether, the trolamine weighing by weight percentage, fully stirred 15～30 minutes mixed solution in the middle of making;
C. in the middle of ethylene glycol butyl ether being added in the mixed solution, stirs mixed in 20～40 minutes after, the adjusting potential of hydrogen is made water-solubility printing ink washing agent of the present invention.
The present invention is based on nonionogenic tenside, the auxilliary aqueous cleaning agent that activates permeate agent that adds again, mainly utilize the amphipathic characteristic of tensio-active agent, promptly in surfactant molecule, there are hydrophilic group and hydrophobic group simultaneously, make it have adsorption on the interface, and the micelle in solution turns usefulness into, reduced surface tension, thereby produce moistening, infiltration, absorption, solubilising, emulsification, peel off, effect and chemical reaction such as dispersion, form stable hydration layer around making ink dirt particulate surface, the ink dirt particle is difficult near each other and deposits.By wiping, disengaging is attached the thing surface and reaches the cleaning purpose.
Ink dirt of the present invention is removed mechanism: because ink dirt is to expect that to connect being membranaceous sticking to is cleaned on the thing, when cleaning printing ink with washings, the wetting surface to be cleaned of surfactant soln at first, the permeate agent trolamine assists tensio-active agent to infiltrate through in the ink dirt, wet the surfactant soln of surface to be cleaned, to cut off because of the long-chain that connects material formation in the printing ink, ink dirt " is crispaturaed ", be that ink dirt is by the original surface to be cleaned that is tiled in, the glomeration of crispaturaing, by wiping, leave surface to be cleaned.
Ethylene glycol butyl ether among the present invention is that ethylene glycol monobutyl ether is a solubilizing agent, and its solublization shows: have when surfactant polyoxyethylene octyl phenolic ether or polyoxyethylene nonylphenol ether form micella in the aqueous solution after organic solubleness insoluble or that be slightly soluble in water is enlarged markedly.Promptly when surfactant concentration in the scavenging solution during greater than micelle-forming concentration, printing ink also can be removed by solubilising.Nonionogenic tenside with polyoxyethylene chain can will be contained in the outer field polyoxyethylene chain of micella by printing ink, by wiping printing ink is removed from surface to be cleaned.The micelle-forming concentration of nonionogenic tenside is very little, and a large amount of greasy dirts is owing to solublization is removed.Its mechanism be crispatura and emulsifying effect under the printing ink do not removed further removed.
The present invention be a kind of with the nonionogenic tenside be main be the water-base ink cleaning agent of the performance gentleness of solvent with water, all that can be widely used in except that hydroaropic substance are printed the cleaning at inking positions.This cleaning agent formula is simple, simple for production, stable performance, colourless nontoxic, do not corrode pollution-freely, be applicable to that the printing ink of printing machinery cleans, can clean all printing inking positions such as forme, blanket, rubber roll, also be suitable for machine washing through the fine setting froth breaking, and be suitable for the operator and wipe printing ink on hand, the cleaning clothes etc.Its cleaning efficiency height, safe and reliable, raw material supply is convenient, and is with low cost, easily stores, easy to use, compare with all kinds of detergent for ink of selling on the market, wide accommodation, cleaning performance is better, has the potential economic benefit.Erosion resistance experiment of the present invention:
Get water-solubility printing ink washing agent 300ml of the present invention in the 500m1 beaker, respectively with common stainless steel material, gravure with the metallograph base, respectively cut 3 * 10cm from iron sheet, the tinsel that sprays paint, aluminium skin, rubber, washing nylon material etc., put into this clean-out system and soak, observe;
The washing nylon material:
After 20 minutes, no change;
After 30 minutes, the slicing edge adularescent is muddy to be occurred, and does not have obvious swelling;
After 1 hour, the swelling phenomenon is arranged;
After 4 hours, have and obviously dissolve phenomenon.
Other materials:
After 48 hours, there is not any corrosion phenomenon.
The technical indicator of water-solubility printing ink washing agent of the present invention:
The pH value: 7～8,
Outward appearance: colourless transparent liquid.
