Abstract
The present invention relates to a detergent for printing ink and a preparation method thereof. The detergent belongs to the technical field of cleaning printing ink. The detergent is characterized in that solution A and solution B are used to be mixed to prepare the detergent. The solution A is composed of fatty alcohol and ester, and the solution B is composed of organic acid and water. The detergent for printing ink of the detergent has the advantages of favorable effect of cleaning printing ink rollers and rubber sheets, no easy combustion and no environment pollution and is a novel detergent product for printing ink with high efficiency, no nuisance and combustion resistance.
Description
One, technical field
The invention belongs to printing-ink cleaning technique field, specifically is that a kind of printing industry that is used for is cleaned detergent for ink of ink roller, blanket and preparation method thereof.
Two, background technology
Ink roller, blanket to offset press often carry out care and maintenance, are the basic guarantee of printing off the high quality printing product.And the main means of maintenance ink roller and blanket are to clean, and promptly with clean-out system printing ink residual on ink roller and the blanket and other impurity are washed.
For the cleaning of printing-ink, can be divided into three kinds of situations: the one, the cleaning routinely after printing every day finishes, the 2nd, change the preceding colour changing of mass colour and clean, the 3rd, maintenance property cleaning completely regularly.Though clean-out system is the subsidiary material of printing, because of consumption is big, its economic benefit and social benefit can not be ignored.
Traditional clean-out system that is used for ink roller, blanket is gasoline and kerosene, and JP09059682A and EP0791456A have reported and used ether organic solvent.Though this class clean-out system of gasoline, kerosene and ether has certain cleaning performance, but it is inflammable and explosive, it is very dangerous to store use, volatile matter wherein is contaminate environment also, be detrimental to health, and gasoline, kerosene can not remove adherent paper hair on ink roller and the blanket, also ink roller and blanket all be had the swelling effect, frequent cleaning makes its surface be full of cracks occur, reduces work-ing life.In order to address the above problem, the someone develops the detergent for ink of gasoline replacing, kerosene.WO9703136A has invented and has added the novel printing ink cleaning agent of Fatty Alcohol(C12-C14 and C12-C18), emulsifying agent and aromatics in the aliphatic hydrocarbon, but still exists the problem of safety and environmental protection aspect.CN1083501A has proposed by the aliphatic hydrocarbon that contains 5-8 carbon atom, water, anhydrous sorbitol (straight chain) fatty acid ester, polyoxyethylene sorbitan fatty acid ester, lipid acid and mineral alkali or organic bases, the novel printing ink cleaning agent that carries out thorough mixing, emulsification, stablizes, processes with colloidal mill, its component is more, making equipment and program complexity, cost is higher.
Three, summary of the invention
The purpose of a kind of printing ink washing agent of the present invention and preparation method thereof is the shortcoming that overcomes prior art, discloses a kind of efficient, pollution-free, printing ink washing agent and preparation method thereof cheaply.
Clean-out system of the present invention is by lipophilicity and to have certain water miscible Fatty Alcohol(C12-C14 and C12-C18), ester, organic acid and water formulated according to certain method under certain condition.The content of composition is: Fatty Alcohol(C12-C14 and C12-C18) 15～40wt%, and ester 20～55wt%, organic acid 10～45wt%, water 15～35wt%, wherein said Fatty Alcohol(C12-C14 and C12-C18) are methyl alcohol, ethanol, Virahol, 1,2-propylene glycol, glycerol, propyl carbinol or hexalin; Wherein said ester is methyl acetate, ethyl acetate, n-propyl acetate or butylacetate.
Above-mentioned printing ink washing agent is characterized in that: described organic acid is formic acid, acetate, oxalic acid, lactic acid, thionamic acid, oxyacetic acid, 2 hydroxy propanoic acid, citric acid or ethylenediamine tetraacetic acid (EDTA).
The preparation method of above-mentioned printing ink washing agent is characterized in that: earlier Fatty Alcohol(C12-C14 and C12-C18) and ester are made into A solution, again organic acid and water are made into B solution, prepare this product with A and B at last;
The preparation of A solution: under 25-30 ℃ of agitation condition, described Fatty Alcohol(C12-C14 and C12-C18) and ester are pressed the 20-40 weight part: the mixed of 25-35 weight part, stir after 5 minutes, make A solution;
The preparation of B solution: under 25-35 ℃ of agitation condition, with described organic acid and water in the 15-30 weight part: the ratio of 15-25 weight part alternately adds in the container, mixes the back restir 5-10 minute, makes B solution;
Then A solution and B solution are alternately constantly added in the container, slowly be warmed up in the 25-70 ℃ of temperature range, and keep quick stirring more than 2000 rev/mins simultaneously, continue to stir 10-15 minute after adding liquid, must this product after the cooling.
The preparation method of above-mentioned printing ink washing agent is characterized in that: described organic acid is formic acid, acetate, oxalic acid, lactic acid, thionamic acid, oxyacetic acid, 2 hydroxy propanoic acid, citric acid or ethylenediamine tetraacetic acid (EDTA); Described water is general tap water.
The present invention compared with prior art has following advantage:
The present invention is because by two kinds of solution compositions, it can dissolve effectively in the printing ink the connection material and attached to the glue-line and the paper hair of ink roller and blanket surface, improved cleaning performance, simultaneously ink roller and blanket are not had swelling action, can prolong its work-ing life.The present invention has flame retardant resistance preferably owing to used the nonflammable aqueous solution, can prevent disaster hidden-trouble, and simultaneously, all raw materials all are nontoxic, all is friendly to people or environment therefore.In a word, detergent for ink of the present invention can thoroughly be removed printing ink and other impurity on ink roller and the blanket, and environmentally safe is difficult for catching fire, and is nuisanceless, is a kind of detergent for ink efficiently.
