Abstract
The invention relates to environmental-friendly type energy-saving LED (Light Emitting Diode)-UV (Ultraviolet) silk-screen printing ink. The environmental-friendly type energy-saving LED-UV silk-screen printing ink is prepared from the following raw materials in parts by weight: 51 to 58 parts of acrylate prepolymer, 15 to 19 parts of reaction monomers, 12 to 15 parts of pigment, 1 to 4 parts of dispersing agent, 0 to 5 parts of filling agent, 7 to 10 parts of photosensitizer and 0 to 1 part of polymerization inhibitor. The environmental-friendly type energy-saving LED-UV silk-screen printing ink is solidified and dried through a UV-LED light source. The environmental-friendly type energy-saving LED-UV silk-screen printing ink disclosed by the invention contains no poisonous substances, cannot generate ozone, has no odor and contains no benzenes and aromatic organic solvents, a light resisting membrane is nonflammable and cannot deform, the contact temperature is below 70 DEG C, drying is fast, solidification and cross linking can be realized within 2 to 3 seconds, the fastness of a printing product is good, and no radiation light is generated; the environmental-friendly type energy-saving LED-UV silk-screen printing ink can be used for food packaging and metal printing of a medicine packaging machine and is safer and more environmental-friendly.
Description
Technical field
The present invention relates to ink industry field, particularly relate to a kind of environment-friendly type energy-saving LED-UV ink for screen printing and preparation method thereof.
Background technology
Ink by chromoplastid (as pigment, dyestuff etc.), low-melting ink vehicle, fill out the uniform mixture that the materials such as (filling) expects, additional material form; Can print, and dry in printed body; It is the pulpous state adherent having color, have certain degree of mobilization.Ink is for the formation of graph text information in printing process, and therefore ink effect is in press not insignificant, and it directly determines the contrast, color, sharpness etc. of printed matter epigraph.Because silk-screen printing technique is of many uses, less investment, other printing processes are difficult to the stock printed, and all use silk screen printing, thus the silk-screen process nearly more than ten years obtain develop rapidly.
The technique of silk screen printing for many years: plate-making on silk screen volume, ink is made to be printed as picture by blank parts by scraper plate of biting, its drying adopts absorptivity dry, volatility (organic solvent volatile dry) air drying, the various ways such as Far infra-red hot is dry, energy consumption is large, and time of drying is long, the shortcomings such as efficiency is low, do not meet the high speed printing requirement of printing industry.And the source of pollution that ink has become Printing industry maximum, world's ink annual production has reached 3,000,000 tons.Annual global organic volatile (VOC) discharge amount of pollution caused by ink has reached hundreds of thousands of ton.These organic volatiles, can form the Greenhouse effect more serious than carbonic acid gas, and can form oxide compound and photo-chemical smog under irradiation by sunlight, major polluting atmosphere environment, affect health of people.In addition, food, in the packages printing common inks such as toy, the harmful composition such as heavy metal also can directly endanger the healthy of eater.
Summary of the invention
In order to solve slow, the dry difficulty of traditional ink for screen printing curing speed, pick resistance is poor, energy consumption is large and the problem such as seriously polluted, the invention provides a kind of environment-friendly type energy-saving LED-UV ink for screen printing.
The object of the invention is to be achieved through the following technical solutions:
Environment-friendly type energy-saving LED-UV ink for screen printing, calculate with weight ratio, comprise the acrylic ester prepolymer of 51 ~ 58 parts, 15 ~ 19 parts of reaction monomers, 12 ~ 15 parts of pigment, 1 ~ 4 part of dispersion agent, 0 ~ 5 part of weighting agent, 7 ~ 10 parts of light triggers and 0 ~ 1 part of stopper, this ink is by the light source curing drying of UV-LED.
Further, described acrylic ester prepolymer with the low-grade polymer of modified epoxy acrylic ester, the polymkeric substance of modified polyester acrylate ester, in the oligopolymer of polyurethane-modified polyacrylate and 6-hexanediyl ester one or both, according to the difference of printing material, carry out different selections.
Further, described reaction monomers is Acrylic Acid Monomer, and without limiting especially, conventional difunctional monomer has 1,6 hexanediol diacrylate, ethoxyquin-1,6-hexylene glycol, ammediol acrylate etc.; Conventional trifunctional monomer has tetramethylolmethane-3 acrylic acid ester, 3-hydroxymethyl-propane-3 acrylic acid ester, ethoxyquin-3-hydroxymethyl-propane-3 acrylic acid ester etc.; Conventional polyfunctional monomer has two-3-hydroxymethyl-propane-4-acrylate, 2-tetramethylolmethane-6-acrylate, and the third oxidation-tetramethylolmethane-4 acrylate etc., it can be used alone or two or more common use.
Further, described pigment, without specific restriction, can be carbon black, phthalocyanine blue B, fuchsin, bronze red, Rutile type Titanium Dioxide or diarylide yellow etc.;
Further, described dispersion agent is macromolecular organic compound, and it is adsorbed in solid particles surface and forms adsorption layer, makes the solid particles surface of cohesion be easy to moistening; Improve and form the intergranular reactive force of steric hindrance, between solid particulate because of electrostatic repulsion away from, make system even, suspension property increases, and does not precipitate, makes whole system physico-chemical property the same;
Further, described weighting agent is flatting silica, aerosil, aluminium weighting agent or calcium weighting agent;
Further, described light trigger is 1-hydroxyl 2-methylpropiophenone class, 1-hydroxycyclohexyl phenyl ketone class, Three methyl Benzene hydroxyl oxidize phosphorus, 2,4,6-trimethylbenzoyl phenyl phosphinic acid ethyl ester, dimethylamino benzyl morpholinyl phenyl butanone, o-benzoyl yl benzoic acid methyl esters, dimethylamino benzyl morpholinyl phenyl butanone, light trigger 784, formylphosphonic acid ethyl ester, a kind of or two or more mixture in light trigger 907 and light trigger 2959;
Further, described stopper is without special restriction, conventional has three (N-nitroso-group-N-Phenylhydroxylamine) aluminium salt, Resorcinol, para benzoquinone, toluhydroquinone, MEHQ, 2-Tert.
