preparation example Construction

[0031] The preparation method according to the UV conductive ink of above-mentioned composition is:

[0032] The preparation of UV flexo conductive ink adopts dispersion method. The dispersion method refers to the use of various machinery to change the coarse particles into fine particles by means of grinding and crushing. It is a physical method.

[0033] 1. Preparation of conductive paste:

[0034] Mix the conductive material, prepolymer, monomer and dispersant, stir the mixture with a stirrer for 30 minutes for pre-dispersion, add the prepared grinding beads, and use a high-speed grinder to grind for 3 hours at a grinding speed of 1800r / min. The material is fully wetted and dispersed to obtain a conductive paste.

[0035] 2. Preparation of ink

[0036] Mix the ground conductive paste, film-forming resin, monomer and photoinitiator, put it in a vessel, put it on a HJ-6A digital display constant temperature multi-head magnetic stirrer, stir at a constant temperature of 40 ...

Embodiment 1

[0039] Embodiment 1: 30 parts of conductive materials, 25 parts of prepolymers, 40 parts of monomers, and 5 parts of dispersants are mixed, wherein the conductive materials are spherical silver powders whose product code is MSP-07, and the prepolymers are polyester acrylic resins. Selected from the CN series of SATORMAR company, the monomer is a mixture of commercially available 2-ethylhexyl acrylate, tripropylene glycol diacrylate and neopentyl glycol diacrylate, and the ratio is 2-ethylhexyl acrylate: Tripropylene glycol diacrylate: neopentyl glycol diacrylate=8:4:3 (weight ratio), and the dispersant is a hyperdispersant with an anchor group selected from the CH series of Shanghai Sanzheng Company, using The mixture was stirred by a stirrer for 30 minutes for pre-dispersion, and then ground for 3 hours using a high-speed grinder to obtain a conductive paste. Mix 20 parts of conductive paste, 30 parts of monomer, 40 parts of film-forming resin, and 10 parts of photoinitiator ...

Embodiment 2

[0040]Embodiment 2: 20 parts of conductive materials, 30 parts of prepolymers, 45 parts of monomers, and 5 parts of dispersants are mixed, wherein the conductive materials are spherical silver powders whose product code is MSP-01, and the prepolymers are commercially available vinyl chloride Resin, the monomer is a commercial mixture of 2-ethoxyethoxyethyl acrylate, hexanediol diacrylate and ethoxylated trimethylolpropane triacrylate in the ratio of 2-ethoxyethyl acrylate Oxyethyl ester: hexanediol diacrylate: ethoxylated trimethylolpropane triacrylate = 10:6:1 (weight ratio), the dispersant is a modified acrylate block copolymer selected from BYK The company's byk-9077 uses a stirrer to stir the mixture for 30 minutes for pre-dispersion, and then uses a high-speed grinder to grind for 3 hours to obtain a conductive paste. Mix 25 parts of conductive paste, 25 parts of monomer, 49 parts of film-forming resin, and 1 part of photoinitiator (including hydrogen donor). The monomers...

Abstract

The invention discloses a UV conductive ink and a preparation method thereof. The UV conductive ink comprises, by mass 20-70 parts of a conductive slurry, 10-40 parts of a film forming resin, 10-30 parts of a monomer and 1-10 parts of a photoinitiator. The conductive slurry comprises, by mass, 20-50 parts of a conductive material, 10-30 parts of the a prepolymer, 2-40 parts of a monomer and 1-15 parts of a dispersant. The preparation method comprises the following steps: mixing the conductive material with the prepolymer, the monomer and the dispersant, stirring the above obtained mixture for 30min for pre-dispersion, and grinding by a high-speed grinding machine at a grinding speed of 1800r / min for 3h to make the above obtained material fully wetted and dispersed in order to obtain the conductive slurry; and mixing the conductive slurry with the film forming resin, the monomer and the photoinitiator, putting the newly obtained mixture into a vessel, arranging the vessel on an HJ-6A type digital thermostat long magnetic stirrer, and carrying out thermostatic stirring at 40DEG C for 0.5h until uniformity to obtain the ink. The production process of the UV conductive ink has little pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of ink, and relates to a UV conductive ink and a preparation method thereof. Background technique [0002] According to the analysis of NanoMarkets market research company, the conductive ink market will develop into a very large industry in the near future. By 2015, the total value of the conductive ink market will triple to 2.4 billion US dollars. UV conductive ink is a kind of functional ink, which can add conductive carrier to UV ink to make the ink conductive. As a green and environmentally friendly functional ink, UV conductive ink has attracted widespread attention in the application prospect of flexographic printing. With the development of new printing technology, the application prospect of UV flexographic conductive ink in the field of printed electronics is getting better and better. [0003] A good UV conductive ink formula requires good printability, and the printed ink layer has the characte...
