Description
Technical field
The present invention relates to printing plate cylinder cleaning technique field, particularly a kind of printing plate cylinder UW aqueous cleaning agent and preparation method thereof.
Background technology
Printing plate cylinder in use need transmit printing ink for a long time, the printing plate cylinder surface irregularity ground tiny ink cell that distributing, and printing ink is through solidifying in ink cell behind the certain hour.Because ink cell is tiny, be difficult to the printing ink flush away in the ink cell.Can stop up ink cell behind the ink solidification, this will have a strong impact on the printing quality that printing plate cylinder prints once more.
The method that printing plate cylinder cleans mainly contains artificial scouring, high pressure water sprays and UW shakes washes; The above two are most of at present method that producer uses of printing; But the both can not clean up the residual ink in the ink cell, and is very big to the printing quality influence of printing plate cylinder; UW shake wash be the high energy impact events wave energy that produces through UW enough with the printing ink in the ink cell shake, dispersion, emulsification; If just water or common clean-out system are as medium; To thoroughly printing ink be cleaned up, often need shake continuously and wash tens hours even tens hours.
Drawbacks such as existing printing plate cylinder UW aqueous cleaning agent exists with an organic solvent, cleaning efficiency is low; Like disclosed 200910228263.7 patents of Chinese patent communique the inside a kind of ultrasonic cleaning agent is provided; Mainly consist of organic solvent ODS (methylal) and gamma-butyrolactone; Wherein methylal is the volatile combustiblematerials of pungency, and GBL is a combustiblematerials, and that this type product with an organic solvent exist to use is dangerous, human body is had problem such as certain harm; The detergent for water-based print ink that a kind of water-base ink cleaning agent that provides like Chinese patent 201010100923.6 the insides and Chinese patent 200510136619.6 the insides provide; Its effective ingredient is tensio-active agent and alkaline, inorganic salts etc.; Only be suitable for cleaning and spray Cleaning for High Capacity; Cleaning efficiency is lower, and is not applied in the ultrasonic cleaning technology.
Summary of the invention
The object of the present invention is to provide a kind of printing plate cylinder UW aqueous cleaning agent, it can clean in the printing plate cylinder ink cell solidified printing ink fast, neatly, this aqueous cleaning agent can not corrode printing plate cylinder, nontoxic, not flammable, can repeat safe handling.
Technical solution proposed by the invention is such:
A kind of printing plate cylinder UW aqueous cleaning agent, said aqueous cleaning agent component is expressed as with mass percent: boric acid ester tensio-active agent 3 ~ 5; Inorganic alkaline thing 2 ~ 4; Metal inhibitor 0.5 ~ 1; Sequestrant 0.5 ~ 1; Permeate agent 1 ~ 3; AS 0.4 ~ 0.6; Surplus is a pure water.
The component of said boric acid ester tensio-active agent is expressed as with mass percent: LAURIC ACID 99 MIN Soxylat A 25-7 40 ~ 50, terepthaloyl moietie amine 25 ~ 30, boric acid 20 ~ 30; It is mixed back stirring under 70 ~ 90 ℃ made the boric acid ester tensio-active agent in 1 hour.Said inorganic alkaline thing is by sodium hydroxide and water glass, combine by 1:08 ~ 1.2 mass ratioes.Metal inhibitor adopts organic amine with ∕ or organic imidazoles; Said organic amine is selected trolamine or diethylolamine for use; Organic imidazoles is selected benzimidazolyl or benzotriazole for use.Said sequestrant adopts Trisodium Citrate with ∕ or sodium malate;
When sequestrant is made up of Trisodium Citrate and sodium malate, combine by 1:1.5 ~ 2.5 mass ratioes.Said permeate agent is for selecting polyoxyethylene nonylphenol or polyoxyethylene octylphenol ether for use.Said AS adopts sodium lauryl sulphate or X 2073.
The preparation method of said printing plate cylinder UW aqueous cleaning agent is: at room temperature; Inorganic alkaline thing, metal inhibitor, sequestrant are added in the mixing kettle by proportioning; Add in the mixing kettle after being heated to 60 ~ 65 ℃ by the half the pure water of proportional quantity; Be stirred to dissolving fully, in mixing kettle, add boric acid ester tensio-active agent, permeate agent and AS again, add the pure water of 60 ~ 65 ℃ of surpluses by proportioning; Be stirred to dissolving fully, obtain printing plate cylinder UW aqueous cleaning agent behind the naturally cooling.
The mechanism that cleaning and removing of the present invention is removed residual ink in the printing plate cylinder ink cell is: because residual printing ink is to be to connect the membranaceous material that material forms with the resin on the printing plate cylinder, printing plate cylinder is had certain sticking power.Boric acid ester tensio-active agent in the clean-out system and permeate agent, when using together, AS produces synergy; Have very strong perviousness and dispersive ability, under alkaline environment, can be adsorbed on ink pellet surface, ink pellet surface is wetting, emulsification rapidly; And reduce the IT of printing ink rapidly; Penetrate into the fine clearance between printing ink and the printing plate cylinder simultaneously, thereby, the sticking power of printing ink on printing plate cylinder reduced.Under high-octane hyperacoustic shock action, printing ink is broken up at short notice, is come off, emulsification, be distributed in the clean-out system, thereby reaches the clean purpose of Rapid Cleaning.
Compared with prior art, the present invention has following unusual effect:
(1), owing in clean-out system, adopted this tensio-active agent of boric acid ester tensio-active agent, this material has good penetration property and dispersive ability, can rapidly that printing ink is wetting, emulsification, and stable in properties, nontoxic, non-volatile.Thereby the cleansing power of aqueous cleaning agent is strong, and cleaning speed is fast, and cleaning efficiency is high.Compare with existing common clean-out system, this aqueous cleaning agent only needed just can the residual ink of printing plate cylinder thoroughly be cleaned up in 30 minutes, and cleaning efficiency improves more than 20 times.
(2), the main body composition of this aqueous cleaning agent is water, has advantages such as nontoxic, not flammable, non-volatility, the erosion printing plate cylinder that is stale-proof, environmental pollution are little, safe in utilization.
(3), this aqueous cleaning agent blending process is simple, with low cost, product performance are stable, and are repeatedly reusable, have vast market prospect.
