Description
Technical field
What the present invention relates to a kind of IPC classification C09D, C09F field is applicable to the soybean oil resin printing ink that is applied in the resin ink vehicle, especially a kind of heat-cured soybean oil resin rotary offset litho ink.
Background technology
The used printing ink of thermofixation offset lithography rotary press of China's introduction in recent years contains the petroleum solvent up to 35-42%, these solvents mainly are made up of the aromatic hydrocarbons of alkane and 10-30%, can cause the hazardous solvent concentration in printing place to surpass the permission standard, printed matter surface hazardous solvent residual quantity also will exceed standard greatly.Traditional concept is thought, though the soybean oil compliance with environmental protection requirements, it belongs to semi-drying vegetables oil category, is difficult to solve the high quality problem that require in the high speed printing fast does, dirty and printing are not stained with in the back side.In relevant this type of open source literature, as CN1415673A, CN1410495A, CN0310748A, CN1239123A, CN1079488A and CN14720282A have disclosed the contriver and provide the technical scheme of oneself with regard to the problems referred to above and used for reference on the current printing ink market and to have utilized soybean oil to make not only compliance with environmental protection requirements but also can reach the research and development advantage of the accomplished fact of the printing ink that printing technology requires from different sides.But, high-quality needs are primary forever, meet environmental protection requirement even if given prominence to, the prescription of its printing ink, the processing requirement of preparation be reflected in such as low-melting ink vehicle, auxiliary low-melting ink vehicle, soybean oil be difficult on the exsiccant problem and how suitably an amount of use also exist on the technical problems such as flow agent, antifriction liniment, siccative continue to improve, continuous perfect space.
Summary of the invention
In order to solve the thermofixation rotary offset litho ink owing to containing harmful pollution problem that the bulk petroleum solvent causes air and printed matter surface, the present invention has adopted the soybean oil of compliance with environmental protection requirements to make the soybean oil resin ink vehicle, further makes the high-quality printing ink that is applicable to thermofixation offset lithography rotary press.This printing ink has not only been eliminated the environmental pollution that petroleum solvent caused, and can make printing have high quality level.Simultaneously, the printing ink process for making has been quoted international advanced person's " flushed color paste " method and to " squeezing method " technology of carbon black, can have been guaranteed that this printing ink has high quality and lower cost.For this reason, the present invention addresses the above problem the technical scheme of being taked: a kind of heat-cured soybean oil resin rotary offset litho ink comprises based on rosin/alkylphenol phenolic resin, cooperates tung oil or oleum lini or Chinese catalpa oil to make the main low-melting ink vehicle (A) of sylvic oil with soybean oil in the feed composition of its printing ink; With soya-bean oil/isophthalic alkyd resin (B) with replace the auxiliary low-melting ink vehicle of light colour petroleum resin oil whole or most petroleum solvent (C) with soybean oil; And the alkenes low-molecular(weight)polymer (D) that can mix with petroleum solvent or vegetables oil; Wherein, described printing ink can be made the printing ink of magenta ink, middle yellow ink, sky blue printing ink, black ink and other color and luster respectively by the feed composition weight percent, and their combination raw materials separately number by weight percentage are respectively:
| Raw material | Magenta ink | Middle yellow ink | Sky blue printing ink | Black ink |
| Resin pigment and other auxiliary agents of inserts isoprene copolymer tung oil soybean oil petroleum solvent | 33.2 21.0 2.0 6.2 28.5 6.6 2.5 | 34.8 17.0 3.0 6.2 29.5 7.0 2.5 | 34.9 18.4 2.0 6.2 29.0 7.0 2.5 | 35.5 20.3 2.0 4.5 27.0 9.0 1.7 |
Compare prior art and products thereof, the present invention has outstanding substantive distinguishing features and significant technical progress is fairly obvious:
(1) the present invention has selected a kind of rosin/alkylphenol phenolic resin of high viscosity and high dissolvability energy for use, cooperate other dry vegetable oil (tung oil with soybean oil, oleum lini or Chinese catalpa oil) make sylvic oil, and make this sylvic oil improve rheological and raising visco-elasticity with a kind of organoaluminum gelifying agent.With this main low-melting ink vehicle (A) as printing ink.
(2) the prepared a kind of soya-bean oil/isophthalic alkyd resin (B) of the present invention and replace the light colour petroleum resin oil (C) of whole or most of petroleum solvent with soybean oil, the auxiliary low-melting ink vehicle as printing ink has better action to the China ink that improves printing ink.
(3) the present invention has selected a kind of alkenes low-molecular(weight)polymer (D), and this polymkeric substance and petroleum solvent, vegetables oil can mix.The chemically reactive of polymkeric substance when heating of utilizing this normal temperature to be in a liquid state improves the curing speed of ink vehicle, solves soybean oil and is difficult for the exsiccant problem.
(4) the present invention by produce the colored ink tinting material " flushed color paste " processing method or produce the processing method of black ink carbon black " squeezing method ", with above-mentioned sylvic oil (A), (B), (C) and alkene polymers (D) cooperate, added the auxiliary agent (flow agent that ink performance is had specific function, the antifriction liniment, siccative etc.), make each color ink that is fit to thermofixation offset lithography rotary press.
