Abstract
The present invention relates to chemical paint technology, and is especially one kind of water thinned polishing oil for offset line and its preparation process. The water thinned polishing oil consists of styrene-acrylate resin emulsion containing three functional monomer and N-hydroxyethyl acrylamide 40-75 wt%, acrylic resin solution 5-30 wt%, filming acrylic acid emulsion 5-20 wt%, wax emulsion 1-10 wt%, water thinned leveling agent 0.5-3 wt%, water thinned defoaming agent 0.2-5 wt% and water for the rest. The present invention has simple preparation process and can reach high printing level.
Description
Technical field
The present invention relates to the chemical coating technical field, be specifically related to a kind of line water lustering oil that is used for offset printing.
Background technology
Printing coating on the replica surface of all finishing the picture and text printing process, prints oil polish once or twice with printing press exactly, makes the print surface obtain the method for the thin film layer of light.Printing coating can strengthen the light fastness of printing ink, increases ink lay solar heat protection and moistureproof ability, plays the effect of protecting trace, beautifying product.Along with the development of society, human protection consciousness to living environment also improves constantly.For printing industry, increased the requirement and the restriction condition of aspects such as many health, environmental protection, labour protection gradually, particularly more strict to the requirement of food product pack printing, only in this way just can meet the requirement of international hygiene standard.Therefore, development and application pollution-free, non-harmful " green " material is imperative.Nontoxic, tasteless, the no organic volatile (V0C) that water lustering oil had, glossiness height, characteristics such as easy to use.Developed country just began to forbid the oil soluble oil polish as far back as the nineties initial stage, and generation water lustering oil become the main flow in market.And the water-based glazing process dissolved in the offset printing press, present " 5+1 ", " 6+1 " offset printing press have appearred, and the line water lustering oil also appears on the market in the U.S. and European Union member countries simultaneously.
Along with the introduction of foreign capitals and technical requirements thereof, the requirement of water-based gloss oil is also being improved constantly.Along with continuing to bring out of the water-based gloss oil of various difference in functionalitys, water lustering oil will become the inexorable trend that China's printing packaging already develops.
At present, the consumption of China's line oil polish also mainly relies on from imports such as the U.S. and Germany about 50,000 tons/year.Water glazing coating and copolymer emulsion resin thereof have been seen research and bibliographical information, and it is raw material, water and ethanol copolymer emulsion synthetic technology or its Preparation of waterborne glazing agent technology as solvent that most of document has related to multiple acrylate monomer copolymer resins.As the disclosed on-line water-based roll-coating glazing oil of Chinese CN02135083 patent " offset on-line water-based roll-coating glazing oil and preparation method thereof) ", wherein used the polyfunctional group acrylic resin that contains hydroxyl and amide group as the preparation composition.But domestic existing line water lustering oil exists a certain distance on glossiness, drying property, wear resisting property.
Summary of the invention
Technical problem to be solved by this invention provides offset printing line water lustering oil that a kind of glossiness is good, wear resisting property is strong and preparation method thereof.
The present invention is achieved by the following technical solutions:
The component content of line water lustering oil of the present invention is as follows:
The styrene-acrylic resin emulsion 40～75% of three-functionality-degree monomer and N-hydroxyethyl acrylamide; Acrylic acid resin solution 5～30%; Film forming acrylic acid emulsion 5～20%; Wax emulsion 1～10%; Water-based flow agent 0.5～3%; Water-based defoamer 0.2～5%; All the other are water.
The manufacture method of water thinned polishing oil for offset line of the present invention comprises following operation:
(1) make the styrene-acrylic resin emulsion:
Concrete synthetic route is as follows:
Being added in agitator in the deionized water with vinylbenzene, butyl acrylate and functional monomer is raw material, use negatively charged ion and nonionogenic tenside to do blending emulsifiers, with Potassium Persulphate and sodium bisulfite is catalyzer, transfer pH value to 8-9. and add polyvinyl alcohol with Sodium phosphate dibasic, in temperature is 50-120 ℃, and agitator speed is that polyreaction makes the acrylate resin emulsion that contains three-functionality-degree monomer and N-hydroxyethyl acrylamide under 500～2500rps/m.
(2) the solid acrylic acid resin with acid number 〉=150mg KOH/g makes the acrylic acid resin solution by the alkaline water dissolving.
(3) speed with 600 rev/mins stirred 120 minutes to add the acrylate resin emulsion that contains three-functionality-degree monomer and N-hydroxyethyl acrylamide, acrylic acid resin solution, film forming acrylic acid emulsion, wax emulsion, water-based flow agent, water-based defoamer successively at the agitator device after, filtered and promptly got product.
The present invention has following unusual effect compared to existing technology:
The offset printing line water lustering oil that is provided among the present invention, when the acrylate resin molecular designing, introduced the three-functionality-degree acrylate monomer, line oil polish film forming hardness of institute and wear resistance can be improved, its water resistance and chemoresistance can also be improved; In molecular resin, add homemade N-hydroxyethyl acrylamide simultaneously as the self-crosslinking agent, crosslinked crosslinked by hydroxyl with amide group, can accelerate the rate of drying after the line water lustering oil prints, improve printing efficiency.
Hectograph line water lustering oil manufacture craft provided by the present invention is simple, and the product transparency is strong, the printed material light, wear resistance is strong, conjunctiva speed is fast, and its performance of hygienic environment-protecting met or exceeded the line water lustering oil of the similar index of import, has filled up a blank of domestic press.
