Embodiment 1

[0013] 1. Preparation of YVO 4 :Eu 3+ ,Sr 2+ Nano phosphor

[0014] (1) Add 1.2mmolNa 3 VO 4 12H 2 O was dissolved in a mixed solution containing 5ml ethylene glycol and 2ml distilled water; (2) The above solution was ultrasonically stirred (80KHz ultrasonic vibration and 300r / min centrifugal speed stirring) and added dropwise with a certain proportion of 1.5mmol Y ( NO 3 ) 3 ·6H 2 O,Eu(NO 3 ) 3 ,Sr(NO 3 ) 2 (0.9:0.03:0.07) in 8ml of ethylene glycol solution, then ultrasonically stirred (80KHz ultrasonic vibration and 300r / min centrifugal speed stirring) for 10min until the solution was clear, then added 20ml of distilled water; (3) Pour the reaction solution into a volume of 50ml In a polytetrafluoroethylene-lined autoclave, in a vacuum environment, 200 o C under heat preservation reaction 1h, down to 150 o C under insulation reaction 1h, after the end of the reaction, cooled to room temperature. The resulting suspension was poured out, centrifuged and washed 3...

Embodiment 2

[0022] On the basis of embodiment 1, the YVO in the step 3 4 :Eu 3+ ,Sr 2+ with YVO 4 :Eu 3+ , Bi 3+ The weight ratio is changed to 1:0.5, and the rest are the same as in Example 1.

Embodiment 3

[0024] On the basis of embodiment 1, the YVO in the step 3 4 :Eu 3+ ,Sr 2+ with YVO 4 :Eu 3+ , Bi 3+ The weight ratio was changed to 1:0.001, and the rest were the same as in Example 1.

Abstract

The invention discloses an offset printing ink. The offset printing ink consists of the following raw materials in parts by weight: 20-30 parts of an ink base, 50-60 parts of a rosin-modified bakelite varnish, 1-5 parts of a fluorine-containing varnish, 1-5 parts of cobalt naphthenate and 10-15 parts of a No.5 solvent, wherein the ink base consists of the following raw materials in parts by weight: 1-5 parts of polyoxyethylene alkylallyl ether, 5-10 parts of alkyd resin, 10-20 parts of the rosin-modified bakelite varnish, 30-40 parts of a No.5 solvent and 20-30 parts of a red-fluorescent light composition; the red-fluorescent light composition is a YVO4: Eu<3+>, Sr<2+>@YVO4: Eu<3+>, Bi<3+> or YVO4: Eu<3+>, Sr<2+>@YVO4: Eu<3+>, Bi<3+>@Ag@SiO2 red-fluorescent light composition. The invention also discloses a preparation method of the offset printing ink. The offset printing ink containing the red-fluorescent light composition is favorable in dispersion stability, a printing surface has low probability of defects, the red-fluorescent light composition is not damaged, meanwhile, the lighting brightness is high, and less red-fluorescent light composition is required.

Description

technical field [0001] The invention relates to an ink for offset printing and a preparation method thereof. Background technique [0002] In the field of art and decoration, on the walls or ceilings of theme parks, hotels, underground passages, trains, etc., artists or craft coating technicians use the above-mentioned paints containing phosphors to draw decorative pictures, etc., and use backlights, etc. Expose it to ultraviolet light to reveal vivid fluorescent color paintings. [0003] Offset printing is a printing method that temporarily transfers ink from a lithographic plate to a rubber cloth, and then transfers the ink on the rubber cloth to the printed surface. When inorganic phosphors with a particle size of several tens of microns are used, defects are likely to occur on the printed surface. Moreover, it is easy to destroy the inorganic phosphor; if the particle size of the phosphor is reduced to the nanometer level, the luminous brightness will be low, which is n...
