Description

Novel printing detergent for ink and preparation method thereof

Technical field

The present invention relates to print cleaning technique field, particularly a kind of novel printing detergent for ink and preparation method thereof.

Background technology

Printing equipment needs the dirts such as routine cleaning greasy dirt and ink marks in process of production.When changing ink kind or print job need the ink on ink roller to clean up after completing, and softening drum, silk screen, press plate and type matrix on printing press can be infected with ink in printing process, for keeping the standard state of printing press and the quality of printed matter also to tackle printing machinery, clean.

Existing detergent for ink is mainly divided into two large classes: a class is vapour, kerosene, and another kind of is the special-purpose novel printing ink cleaning agent of printing.

Gasoline and kerosene are a kind of wide spectrum organism solvents, and proportion is little, and evaporation rate is fast, cheap.In the existing printing house of China, major part is also cleaned ink with gasoline and kerosene.As detergent for ink, there are a lot of shortcomings in gasoline and kerosene: the one, and safety problem, vapour oil flash only has twenties degree, if the ventilation equipment in printing factory building is bad, is easy to the situation of causing danger; The 2nd, pollution problem, gasoline and kerosene, as a kind of organic solvent, have certain toxicity, if Long Term Contact must cause destruction to a certain degree to the healthy of workman and environment around.Novel printing ink cleaning agent is compared with kerosene with gasoline, and cleaning performance is good, and safety performance is high, and little to the pollution hazard of human body and environment.Novel printing ink cleaning agent normally consists of solvent, tensio-active agent, auxiliary agent, water.At present conventional solvent is still from non-renewable solvent oil, and such as kerosene, smell is large, and degradation property is poor, and environment is still existed to certain threat.

Summary of the invention

The object of this invention is to provide a kind of novel printing detergent for ink and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A detergent for ink, is made by the raw material of following weight part: white oil 3-4, ethanol 10-12, acetone 4-5, Virahol 10-12, borax 3-4, saltcake 3-4, sodium carbonate 2-3, tripoly phosphate sodium STPP 1-2, polyoxyethylenated castor oil 12-15, sodium laurylsulfate 1-2, trolamine boric acid ester 2-3, Sodium dodecylbenzene sulfonate 1-2, auxiliary agent 4-5, water 100-110;

Described auxiliary agent is made by the raw material of following weight part: Silane coupling reagent KH-570 2-3, ricinolic acid 3-4, methacrylic acid-2-hydroxy methacrylate 2-3, neopentyl glycol 3-4, vinyl acetate 2-3, oxidation inhibitor 1035 2-3, ethanol 14-16; Preparation method mixes Silane coupling reagent KH-570, ricinolic acid, ethanol, is heated to 60-70 ℃, stirs after 20-30 minute, then adds other remaining component, is warming up to 80-85 ℃, stirs 30-40 minutes, obtains.

Novel printing detergent for ink of the present invention, by following concrete steps, made:

(1) at room temperature white oil, ethanol, acetone, Virahol, borax, saltcake, sodium carbonate, tripoly phosphate sodium STPP are added in mixing kettle, add in mixing kettle after the water of half amount is heated to 65-70 ℃, be stirred to completely and dissolve;

(2) polyoxyethylenated castor oil, sodium laurylsulfate, trolamine boric acid ester, Sodium dodecylbenzene sulfonate are added in mixing kettle, add surplus be heated to 80-90 ℃ water, with the speed of 1400-1500 rev/min, stir 4-5 minute;

(3) finally auxiliary agent and all the other remaining components are added in mixing kettle, stir, naturally cooling.

Excellent effect of the present invention is: the present invention adds auxiliary agent, has improved the processing performance of clean-out system, reduces its toxic side effect and the pollution to environment; The present invention has good dissolved dilution ability to ink; Toxicological harmless, pollution-free, nonflammable explosive; Little to printing press rubber roll damaging action, safety easy to use, suitable for large-scale promotion.
