Description

Printing ink washing agent

The present invention relates to a kind of printing ink washing agent of cleaning printing press, further for cleaning the detergent for ink of uncured printing ink on ink roller, blanket, impression cylinder and the forme.

In the press, the cleaning of printing press ink roller, blanket is an important aided process, a lot of abroad in recent years to this achievement in research, but more is to blanket, the scavenger specially of printing ink residue on cylinder and the forme, for example, Canadian Patent CA1230532 is " the printing cylinder clean-out system " that is exclusively used in printing cylinder, and russian patent SU1409646 and SU1461757 then are " the blanket trace clean-out system " of special-purpose blanket and " the forme clean-out system is newly filled a prescription " that is exclusively used in forme etc.But for being applicable to that printing ink need be actually rare to the versatility detergent for ink that ink roller cleans in form and aspect conversion and other reason.This be since on the ink roller on purging method and the blanket and the forme of printing ink residue the purging method of printing ink residue different.The former removes clean with the discarded printing ink that doctor will dissolve or dilute on plastics or iron ink roller.The latter uses cotton yarn, is stained with behind the clean-out system and removes by hand.Because the lipophilicity, solubleness and the volatility that are used for the cleaning material of ink roller be all than the cleaning material height of blanket, above-mentioned three kinds of clean-out systems are to be not suitable for removing ink residue thing on the ink roller.The clear 63-133000 of Japanese Patent uses the petroleum hydrocarbon boiling point at 200-300 ℃, its content is up to 80%, though therefore it has sizable solubleness and lower volatility, but in fact petroleum hydrocarbon refers to kerosene in above-mentioned boiling spread, and experience shows with kerosene and has a strong impact on print quality as the cleaning material of ink roller.The clean-out system main purpose that world patent WO9014174 proposes is for environment protection, reduces to the airborne release pollutent, thus complex structure, the cost costliness.

Clean the printing ink on the ink roller of offset printing machine in China's printing industry, what use the earliest is gasoline.Gasoline is divided into two kinds on leaded type and not leaded type, and leaded type gasoline contains a large amount of tetraethyl lead compounds, and tetraethyl lead can directly be absorbed by skin, causes lead poisoning; Not leaded type gasoline though there is not tetraethyl lead, contains a large amount of volatile oil.Volatile oil is mixed by Skellysolve A and normal hexane, and boiling point is very low, between 30 ℃-90 ℃.Volatile oil has narcoticness, can suppress people's nervus centralis, is very easy to cause septicemia.The flash-point of gasoline is very low to be 21 ℃, is a kind of combustible liquid of very easily waving.Therefore, although gasoline has the ability of very strong decontamination China ink, the effect of cleaning printing ink is better, but because of very big to the human injury, environmental pollution is serious, be again the hidden danger of fire, after World War II, new detergent for ink is just set about researching and developing by some countries of press prosperity and attention environmental protection in the world, meanwhile, " gasoline " of being described as first-generation detergent for ink by people also has been eliminated gradually.

Novel flexographic ink clean-out system is by solvent, the liquid that rubber anti-ageing agent etc. mix, and adding a certain amount of water can use.Printing ink is had washing force well, the glue-line of ink roller is expanded or contraction.Flash-point is that 21 ℃-55 ℃ clean-out system is an inflammable liquid, is called s-generation detergent for ink by people, as CN1231313A patent disclosure text, and contains the aromatic hydrocarbon substance of harmful benzene ring structure in this invention detergent for ink.

Since the nineties, the widespread use of technology in offset printing before the seal such as the colored desktop publishing of laser photo-typesetting, make the lithography of China obtain significant progress, domestic offset press has obtained maximum amplitude ground to be increased, but during the printing ink on cleaning ink roller of offset printing machine, what domestic most of producers still used is gasoline, even use plumbiferous gasoline, a large amount of obnoxious flavour disperses not only jeopardize health of human body in the workshop, set up various fp facilities but also cost.The producer that has uses kerosene to clean ink roller, but very slow because of the evaporation rate of kerosene, is stranded in the ink roller surface for a long time, can make the glue-line swelling of ink roller, cause the variation of ink roller size, cause the offset press inking inhomogeneous, influence quality product, influence the social benefit and the economic benefit of printing industry.Arrived at present necessary change when cleaning rubber roll with gasoline, therefore, printing industry is looked forward to always can be had a kind of nuisancelessly, and dynamical detergent for ink occurs, in order to replace gasoline and the kerosene that cleans as printing ink commonly used at present.

The object of the present invention is to provide a kind of printing ink washing agent of new formulation, it can overcome in the prior art printing ink a large amount of application of using the aromatic hydrocarbon substance that contains harmful benzene ring structure effectively, and detergent for ink of the present invention is a kind of detergent for ink of new generation of efficient, nuisanceless, non-environmental-pollution.
