The UV photoluminescence ink can be widely applicable for printing on securities, tax receipts, invoices, credit cards and other valuable bills.
Description
Technical field
The present invention relates to a kind of printing UV printing ink, i.e. a kind of UV photoluminescence printing ink for fields such as commodity outer packaging, security, tax reciept, invoice, credits card.
Background technology
The photoluminescence anti-forgery ink has disguised better, in bright gay color, with low cost and anti-counterfeiting technology is implemented the characteristics such as convenient, demonstrates huge application potential in the fields such as valuable bills such as security, tax reciept, invoice, credits card.In recent years, developed multiple light photoluminescence anti-forgery ink both at home and abroad.Such as, Chinese patent CN1544545A discloses a kind of long persistence luminescent painting ink, Chinese patent CN1313364A discloses a kind of luminous ink paint, Chinese patent CN1143659A discloses a kind of universal colorful luminescent ink, Chinese patent CN1465631A discloses a kind of non-emissive property enviroment protective energy storage luminous ink, Chinese patent CN1059544A discloses a kind of permanent shining printing ink, Chinese patent CN1114967A discloses a kind of flash of light that has, the phosphorescent coating of luminescent properties, Chinese patent CN1125746A discloses a kind of luminous paint with ultra-long afterglow, Chinese patent CN1542060A discloses a kind of luminous paint etc.After the printing ink that above-mentioned patent relates to is subject to excited by visible light, all can continue at the dark place luminous, but not anti-solvent is arranged, hardness is low, crocking resistance is poor, contaminate environment, affect the shortcomings such as operator are healthy, its dried forms is high bake, energy consumption is large, and efficient is low.
UV curable ink, i.e. UV printing ink, be a kind of can be dry under UV-irradiation, the printing ink of film forming.Owing to do not use solvent, to the environment zero release, and need not high bake, be a kind of real environmental protection, energy-conservation printing ink.At present, Chinese patent CN1657575A discloses a kind of UV light solidified luminous printing ink, uses the alkaline earth aluminate of activated by rare earth elements, silicate to be luminescent material, successfully prepares a kind of excited by visible light UV light solidified luminous printing ink.But, because rare-earth substance is strategic material, itself also can cause considerable damage to environment the refinement of rare earth, country strictly controls the links of Rare Earth Production in recent years, and very worthy, therefore, have the defectives such as cost height, raw material sources be unstable based on the luminescent ink of the luminescent material of rare earth background preparation.
Summary of the invention
The excited by visible light, the green UV photoluminescence printing ink that the purpose of this invention is to provide a kind of preparation take ZnS:Cu as luminescent material, this printing ink has solved the not anti-solvent of existing printing ink, hardness is low, crocking resistance is poor, contaminate environment, affect the shortcomings such as operator are healthy, and raw materials enjoy stable sources, cheaply is easy to get.
Technical scheme of the present invention realizes that by following approach the implementation step is as follows:
(1) surface modification of luminescent powder
Because the ZnS:Cu luminescent powder is inorganic particle, have hydrophilic surface, and prepolymer is lyophobic dust such as epoxy acrylic resin and polyester acrylate resin etc., mixes in order to make both, must carry out surface modification to luminescent powder.Take by weighing 1 kilogram of ZnS:Cu luminescent powder and add in the high mixer, 80 ℃ of design temperatures mixed two hours; Take by weighing in the 25 gram silicone oil adding high mixers and mixed 10 minutes with luminescent powder, realize the surface modification to luminescent powder
(2) printing ink preparation
Described photoluminescence UV printing ink, the weight percent content of each raw material (wt%) is:
Prepolymer 30.0%-56.0%
Modification luminescent powder 30.0%-50.0%
Promotor 2.0%-5.0%
Diluting monomer 3.0%-6.0%
Light trigger 1.0%-5.0%
Defoamer 0.5%-5.0%.
After prepolymer, light trigger, diluting monomer, promotor weighed up by above-mentioned prescription, putting into successively black had lid to be in harmonious proportion bucket, and then stirring at low speed adds the modification luminescent powder to dissolving, and high-speed stirring is 30 minutes again.Defoamer divides two portions to add, and a part adds in whipping process, and another part adds when stirring is finished soon.Can obtain at last photoluminescence UV printing ink.
The invention has the beneficial effects as follows:
(1) the present invention utilizes high-performance ZnS:Cu luminescent powder to be raw material, raw materials usedly cheaply is easy to get, and is with low cost;
(2) the present invention has carried out surface modification to the ZnS:Cu luminescent powder, is conducive to it and fully is distributed in the prepolymer, has promoted the press quality of printing ink;
(3) the present invention uses epoxy acrylic resin and polyester acrylate resin compound to be prepolymer, can effectively regulate ink product curing speed, hardness and crocking resistance;
(4) the present invention uses Viscoat 295 and tripropylene glycol diacrylate to be diluting monomer, can effectively regulate solvability and the viscosity-reducing performance of printing ink, and snappiness and the water tolerance of solidifying rear product.
