Problems solved by technology

[0021] As for the packaging and printing industry (glass, ceramics, metal containers), due to the low individual price, the increase of decoration process cost will greatly affect the product price, so the disadvantage of inkjet ceramic printing process cost will appear
The shortcomings of inkjet ceramic printing equipment: ①The resolution is only 360dpi (the resolution of UV industrial printers can reach 600dpi) ②The ink cannot be dried immediately, the glaze color will be blurred, and the printing texture effect is poor ③High temperature sintering (600°C) is required ④Nozzle And ink needs to be imported

Embodiment

[0058] Embodiment: the preparation of functional ink

[0059] Preparation of functional ink (1)

[0060] Weigh 100g of the mixed component of epoxy resin 1# (E03:E14=3:2), grind it into powder with a mortar, pour it into a 1000ml beaker, and then add solvent 1# (toluene:acetone=1:4) 400g is fully dissolved to obtain a uniform viscous liquid; add curing agent (diaminodiphenylmethane) to 60g, after stirring evenly, add solvent 2# (ethylene glycol methyl ether) 80g while stirring to ensure that the system is always uniform For clarified solution, heat the above system at 50°C and stir slowly for 12 hours, then add 180g of epoxy resin 2# (F44) until it is completely dissolved, then add 9g of accelerator (2E4MZ) until it is completely dissolved, and finally add additives (flow The leveling agent Digo 100 is 0.2g, the antioxidant Chemtura 1076 is 0.3g, and the adhesion promoter Digo LTW is 0.1g).

Embodiment 2

[0061] Embodiment 2: Preparation of UV printing finished product

[0062] Printed product (a)

[0063] Degrease, dust and dry the surface of the glass sheet, spray the water film on the surface of the glass sheet with an aqueous solution of coupling agent Dow Corning 6121 (0.1-0.5%), scrape off and dry (activate), apply the functional ink (1) Fill it into the transparent ink channel of the 3D printer 1024UVHS of DCS Company in the United States (the ink in other channels is the original UV ink), print graphics and texts with transparent ink on the activated glass sheet and dry to ensure that the solvent is completely evaporated, and print color graphics and texts on the transparent ink layer And UV curing, put the printed material into the oven and bake at 160°C for 30 minutes.

Abstract

The invention relates to functional ink for ink-jet printing on the surfaces of special base materials (glass, ceramic and metal) as well as a preparation method and application. The functional ink isprepared from the following ingredients in parts by weight: 5-20 parts of epoxy resin 1#, 10-30 parts of epoxy resin 2#, 1-10 parts of a curing agent, 0.5-5 parts of an accelerant, 25-50 parts of a solvent 1#, 1-15 parts of a solvent 2# and 0.05-2 parts of an adjuvant. The invention further relates to a preparation method, performance parameters and an application method of the functional ink. The functional ink contains the epoxy resin, the curing agent, the accelerant, the solvent and other adjuvant in a proper weight proportion and has the characteristics of excellent stability and high-temperature rapid curing, and adhesive film cured by the functional ink has extremely good adhesive force, water resistance, tenacity and rigidity. The functional ink is particularly suitable for the surfaces of the special base materials such as glass, ceramic and metal and has functions as a transition layer between the surfaces of the base materials and a UV (ultraviolet) ink layer, so that the UV (ultraviolet curing) ink-jet technology can be more broadly applied to industrial production in the fields of printing and packaging as well as embellishment and decoration.

Description

technical field [0001] The invention relates to a functional ink for inkjet printing, which is suitable for the surface of special substrates such as glass, ceramics, metals, etc., and acts as a transition layer between the surface of such substrates and the UV ink layer, so that the UV inkjet The technology is more widely extended to industrial production in the fields of printing, packaging and decoration. Background technique [0002] In our country, all kinds of bills in the digital printing market are beginning to show a stronger and stronger tendency towards personalization, and the potential of personalized printing markets such as telecommunications, postal services, banks, securities, and insurance is huge. In Beijing, Shanghai, Guangzhou, Shenzhen and other places, there are large and small fast printing shops on the street everywhere, which is enough to prove that digital printing has entered our daily life. [0003] In foreign countries, digital printing is wide...
