Embodiment 1

[0041] In parts by weight, take by weighing 12 parts of black pigment, 1 part of phthalocyanine blue pigment, 35 parts of polyester acrylate, 8 parts of ethoxy ethoxy ethyl acrylate (EOEOEA), 6 parts Parts of 2,4-diethylthioxanthone, 5 parts of fumed silica, 1.5 parts of silicone acrylate, 1 part of polyoxyethylene alkylphenol ether, 0.01 part of glycerol monostearate ester, 1 part of phosphate methacrylate monomer, and then mix the above-mentioned raw material components, and pre-disperse them on a glass plate, and then grind them with a three-roll mill until the pigments are evenly dispersed. During the grinding process, adjust the three The gap between the rollers of the roller grinder, and the fineness of the ink is tracked and tested until the fineness of the ink reaches about 5 microns, and the grinding is stopped to obtain the finished product.

Embodiment 2

[0043] In parts by weight, use a balance to weigh 18 parts of black pigment, 2 parts of phthalocyanine blue pigment, 55 parts of epoxy acrylate and polyether acrylate (the ratio of parts by weight of the two is 1:1) to form Prepolymer, 18 parts of tripropylene glycol dipropylene ester (TPGDA) and dipropylene glycol diacrylate (DPGDA) (the weight ratio of the two is 1:1) monomers, 10 parts of 2 -Hydroxy-2-methyl-1-phenyl-1-propanone, 16 parts of kaolin, 2.5 parts of silicone acrylate, 2 parts of polyoxyethylene fatty alcohol ether, 0.1 part of sucrose ester, 3 parts of Silane coupling agent, then mix the above-mentioned raw material components, and pre-disperse on the glass plate, and then grind with a three-roll mill until the pigment is evenly dispersed. And the fineness of the ink is tracked and tested until the fineness of the ink reaches about 5 microns, and the grinding is stopped to obtain the finished product.

Embodiment 3

[0045] In parts by weight, take 14 parts of black pigment with a balance, 1.5 parts of phthalocyanine blue pigment, 50 parts of polyester acrylate, polyurethane acrylate (the ratio of the two parts by weight is 1:1) A prepolymer consisting of 12 parts of ethoxylated trimethylolpropane triacrylate (EO3-TMPTA) and propoxylated trimethylolpropane triacrylate (PO3-TMPTA) (both by weight The ratio of parts is 1:1) composed of monomers, 8 parts of 2-ethylhexyl acrylate, 8 parts of talc, 2 parts of silicone acrylate, 1 part of polyoxyethylene-polyoxypropylene Block copolymer, 0.05 parts of sorbitan fatty acid, 1.5 parts of phosphorus methacrylate monomer, then the above-mentioned raw material components are mixed, and pre-dispersed on a glass plate, and then ground with a three-roll mill until The pigment is dispersed evenly. During the grinding process, adjust the nip gap of the three-roll mill in good time, and track and test the fineness of the ink until the fineness of the ink re...

Abstract

The invention provides UV waterless offset print light disk black printing ink and a preparation method thereof. The UV waterless offset print light disk black printing ink is mainly prepared from the following raw materials in parts by weight: 12 to 18 parts of black pigment, 1 to 2 parts of phthalocyanine blue pigment, 35 to 55 parts of prepolymer, 8 to 18 parts of monomer, 6 to 10 parts of photoinitiator, 5 to 16 parts of filler, 1.5 to 2.5 parts of flatting agent, 1 to 2 parts of wetting agent, 0.01 to 0.1 part of surfactant and 1 to 3 parts of adhesion promoter. The UV waterless offset print light disk black printing ink is prepared by adopting the black pigment, the pigment blue, the prepolymer, monomer, the photoinitiator, the filler and assistants of special kinds, has the advantages such as good anti-scumming property, and excellent rheological property and printing ink transfer property, can be used for light disk surface printing, a fountain solution is not needed to be used in a printing process, the production efficiency is high, the printing quality is good and the production cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of UV curing waterless offset printing ink, in particular to a UV waterless offset printing optical disc black ink and a preparation method thereof. Background technique [0002] Traditional disc printing is usually carried out by screen printing, but due to the defects of the screen printing process itself, there are defects such as low printing speed, poor tone reproduction and poor printing quality when printing discs by screen printing. [0003] Waterless offset printing is a new printing technology, which has been widely used in CD printing in recent years. Waterless offset printing is actually a lithographic offset printing technology. Compared with traditional lithographic offset printing technology, it does not use fountain solution, but uses a special silicone rubber coated printing plate, special ink and a set of strict temperature on the printing machine. The control system to complete the printi...
