Functional ink for ink-jet printing as well as preparation method and application

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...

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 at a high cost

[0024] At present, there are coating products used to improve the adhesion and water resistance of UV inkjet on glass, ceramics, and metal surfaces, such as: Shenzhen Donggang Chemical Co., Ltd. UV-603F-A / B type (suitable for glass surfaces), UV-6125D hand rub type (applicable to metal surface), these two treatment liquids are helpful to improve the adhesion of glass ceramic metal surface, but UV-603F-A / B type belongs to AB liquid that needs to be mixed before use, and there is a time limit At the same time, both models are hand rubbing type, not suitable for industrialized mass production
