Description
Technical field：
The present invention relates to a kind of ink printing ink on cleaning printing press tool, printing mother matrix, ink roller and blanket
Cleaning agent.More specifically, being a kind of environmentally-friendly water-based detergent for ink.
Background technology：
Printing industry must consider making for ink as industrial important component in its printing process
With and cleaning process.For traditional detergent for ink mainly using organic solvents such as kerosene as main solvent, flash-point is low, inflammable and explosive equal danger
Danger, is gradually eliminated.Half novel water-base ink cleaning agent mainly mixes oil, water, although improving flash-point, compares vapour
Oil, kerosene safety, but demulsifying phenomenon can occur using process, and have oil gas effusion, production security is not only influenced, it can also band
Carry out problem of environmental pollution.Therefore production aqueous cleaning agent can abandon gasoline, and the organic solvents such as kerosene prevent from firing problem, again
The generation of VOCs can be reduced.
Currently, aqua type detergent for ink has become the main aspect of domestic and international market research, although technology tends into
Ripe but expensive, cleaning rate is slow, and general effect is undesirable.It is water base relative to mixed solvent type and half aqua type cleaning agent
Detergent for ink is since the advantages that " no flash-point, does not corrode, of low pollution ", receives significant attention, but water-based inks currently on the market
The shortcomings of cleaning agent cleaning performance is undesirable, and the strong basicity auxiliary agent of addition causes to corrode the surface of cleaning workpiece.
Invention content：
The present invention for the existing water-base ink cleaning agent cleaning performance in market it is bad and can not simultaneously cleaning equipment, galley
The shortcomings of material, blanket and printing mother matrix, propose that a kind of cleaning performance is good, etch-proof environmentally-friendly water-based detergent for ink.
Another object of the present invention is to provide the preparation method of above-mentioned environmentally-friendly water-based detergent for ink.
The specific technical solution of the present invention is as follows：
A kind of environmentally-friendly water-based detergent for ink, is formulated by the component of following mass percent：
The further design of the present invention is：
The surfactant is 1 in mass ratio by anion surfactant and nonionic surfactant：2~4 is multiple
With into.
The anion surfactant preferred fatty acid methyl ester sulfonate (MES)；Nonionic surfactant is selected from ten
Dialkyl group glucoside (APG), sorbitan fatty ester (sorbester p17) or fatty alcohol polyoxyethylene ether (AEO-9) are a kind of
Or two kinds of mixing.
Builder selects both laminated crystal of sodium disilicate and metasilicate pentahydrate sodium in mass ratio 1~4:1 mixing.
Solubilizer selects butyl acetate and one kind in absolute ethyl alcohol, urea, diethylene glycol dimethyl ether, propylene glycol or isopropanol
Or two kinds in mass ratio 1：0.5~2 mixing.
Chelating agent is one kind in polyacrylic acid (PAA), sodium gluconate, aminotriacetic acid.
Antirust agent is one kind in benzotriazole, toluic acid sodium, methenamine.
The preparation method of above-mentioned environmentally-friendly water-based detergent for ink, this approach includes the following steps：It is weighed in the above ratio
Surfactant is first added to the water and is sufficiently stirred, make it completely dissolved at room temperature by each component, then by builder, solubilizer
Above-mentioned solution is added, is eventually adding other auxiliary agents, it is to be dissolved completely after, obtained uniform clear liquid is water-based inks
Cleaning agent.
The present invention has the advantages that compared with prior art：
(1) the anion surfactant methyl sodiosul foaliphatate MES that the present invention uses is with natural reproducible grease
It is made of raw material, meets environment protection health idea of development.Part LAS can form complex compound with calcium ions and magnesium ions in water, influence washing performance
Can, and the hard water resistance property of MES is stronger, is not influenced by calcium ions and magnesium ions, biological degradability is good, and mild and stability is high.It can be relatively low dense
The detergency same with higher concentration LAS is shown under degree, advantageously reduces cost and reduces influence of the wash water to environment.
In this formula, reach identical cleaning efficiency, only needs MES1%, and LAS needs 3%, and cleaning rate is 100%.
(2) in the application builder, metasilicate pentahydrate sodium can to light metal provide anti-corrosion protection, and with suspend and
Emulsify dirt and the effect of certain softened water.Metasilicate pentahydrate sodium and laminated crystal of sodium disilicate are mixed, not only improved clear
Wash efficiency, and decontamination, be impregnated with, disperse, emulsify, sterilize, anti-corrosion etc. is better than sodium tripolyphosphate, specifically see the table below.
(3) laminated crystal of sodium disilicate is added in the application cleaning agent, relative to sodium metasilicate, not only there is higher activity
Basicity, pH buffer capacities are strong, and have good synergistic effect for nonionic surfactant, and non-ionic surface can be improved
The adsorption capacity 30% of activating agent.There is certain dispersion performance simultaneously, can also effectively remove and disperse dirt, prevent from sinking again
Product.
(4) the environmentally-friendly water-based detergent for ink of the present invention is safe to use, while cleaning of graphic arts equipment, printing plate, printing
The detergent for ink and preparation method thereof of mother matrix, ink roller and blanket.
