Embodiment 1

[0042] In parts by weight, use a balance to weigh 12 parts of yellow pigment, 30 parts of polyester acrylate, 8 parts of ethoxy ethoxy ethyl acrylate (EOEOEA), 5 parts of 2,4-diethyl Thioxanthone, 5 parts of fumed silica, 1.5 parts of silicone acrylate, 1 part of polyoxyethylene alkylphenol ether, 0.01 part of glyceryl monostearate, 1 part of methacrylic acid Phosphate ester monomer, 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 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 2

[0044] In parts by weight, weigh 17 parts of yellow pigment, 55 parts of epoxy acrylate and polyether acrylate (the ratio of weight and number of the two is 1:1) to form a prepolymer, 20 parts of A monomer composed of tripropylene glycol dipropylene ester (TPGDA) and dipropylene glycol diacrylate (DPGDA) (the ratio of the two parts by weight is 1:1), 8 parts of 2-hydroxy-2-methyl-1 -Phenyl-1-acetone, 18 parts of kaolin, 2.5 parts of siloxane acrylate, 2 parts of polyoxyethylene fatty alcohol ether, 0.1 part of sucrose ester, 3 parts of silane coupling agent, and then mix the above-mentioned raw material components, And carry out pre-dispersion on a glass plate, and then use a three-roller grinder to grind until the pigment is evenly dispersed. During the grinding process, adjust the gap of the three-roller grinder in time, and track the fineness of the ink until the ink is fine. When the degree reaches about 5 microns, stop grinding to get the finished product.

Embodiment 3

[0046] In parts by weight, take 15 parts of yellow pigment with a balance, 40 parts of prepolymers composed of polyester acrylate and polyurethane acrylate (the ratio of the parts by weight is 1:1), 10 parts Ethoxylated trimethylolpropane triacrylate (EO3-TMPTA) and propoxylated trimethylolpropane triacrylate (PO3-TMPTA) (the ratio of the two parts by weight is 1:1) Composed monomers, 5 parts of 2-ethylhexyl acrylate, 10 parts of talc, 2 parts of silicone acrylate, 1 part of polyoxyethylene-polyoxypropylene block copolymer, 0.03 parts of sorbitan fatty acid, 2 parts Phosphorus methacrylate monomer, then mix the above raw material components, pre-disperse on a glass plate, and then grind with a three-roll mill until the pigment is evenly dispersed. During the grinding process, adjust the rollers of the three-roll mill Gap gap, and track the fineness of the ink until the fineness of the ink reaches about 5 microns, stop grinding, and the finished product is obtained.

Abstract

The invention provides a UV waterless offset yellow ink for a compact disc and a preparation method of the UV waterless offset yellow ink. The waterless offset yellow ink for the compact disc is mainly prepared from raw materials in parts by weight as follows: 12-17 parts of a yellow pigment, 30-55 parts of a prepolymer, 8-20 parts of monomers, 5-8 parts of a photoinitiator, 5-18 parts of filler, 1.5-2.5 parts of a leveling agent, 1-2 parts of a wetting agent, 0.01-0.1 parts of a surfactant and 1-3 parts of an adhesion promoter. The UV waterless offset yellow ink for the compact disc is prepared from the yellow pigment, the prepolymer, the monomers, the photoinitiator, the filler and specific types of auxiliaries, has the advantages of good anti-scumming performance, excellent rheological property and ink transfer property and the like, can be applied to compact disc surface printing, does not use a fountain solution in a printing process, and is high in production efficiency, good in printing quality and lower in production cost.

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 CD yellow 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 printing change...
