High-temperature-resistant black exposure and development printing ink, method for preparing same and application

Abstract

The invention provides high-temperature-resistant black exposure and development printing ink, a method for preparing the same and application. The high-temperature-resistant black exposure and development printing ink is applied to the field of decoration of different types of 3D (three-dimensional) curved glass and special-shaped glass. The high-temperature-resistant black exposure and development printing ink is double-component printing ink. A component A of the high-temperature-resistant black exposure and development printing ink comprises epoxy resin, polyester resin, fillers, carbon black, auxiliaries, photoinitiators and cyclohexanone. A component B of the high-temperature-resistant black exposure and development printing ink comprises closed curing agents and butyl acetate. Diluents comprise butanone, butyl acetate and MIBK (methyl isobutyl ketone). The high-temperature-resistant black exposure and development printing ink, the method and the application have the advantages that the curing agents and the diluents can be proportionally added, then the high-temperature-resistant black exposure and development printing ink can be sprayed, 1% sodium carbonate solution can besprayed for 30-90 seconds after the high-temperature-resistant black exposure and development printing ink is preliminarily baked and exposed, unexposed regions can be quickly faded, clear images canbe displayed, and the high-temperature-resistant black exposure and development printing ink is free of residues; the high-temperature-resistant black exposure and development printing ink can be ultimately baked at the temperatures of 150-180 DEG C for 30 minutes, the dried high-temperature-resistant black exposure and development printing ink is excellent in insulating property and good in adhesion, has a high OD (optical density) value and can resist high temperatures, and the problems of low yield and efficiency and high cost of the traditional decoration technologies for 3D curved glass and special-shaped glass can be effectively solved.

Description

technical field [0001] The invention relates to the field of glass decoration inks and protective inks, in particular to a black ink that can be used for spraying and printing decoration of glass windows such as 3D curved mobile phone touch screens, tablet computer screens, liquid crystal displays, and special-shaped parts. technical background [0002] At present, 3D curved screens have begun to enter large-scale applications, but the corresponding 3D curved glass cover production technology is not yet fully mature. In addition to the low production capacity and yield rate of glass thermoforming, there is no way to make decorative patterns on the cover with traditional applications. This is achieved by screen printing of 2D or 2.5D cover plates. The current 3D glass cover decoration technology includes ion coloring technology, laser engraving ink technology, 3D inkjet technology, etc., but the above technologies have disadvantages such as high cost, low production efficienc...
