Problems solved by technology

However, there are many kinds of acrylic resins. Different acrylic resins have different molecular weights and different groups. Different acrylic resins have very different properties, and their effects on ink adhesion are also very different. Moreover, they contain ketones. Organic solvents with high toxicity of ethers
Also said inks have significant disadvantages in terms of adhesion on glass, scratch resistance and resistance to water or solvents

Embodiment 1

[0022] The dark green silver ink of the present embodiment is used in parts by weight: 25 parts of silver powder, 5 parts of red ink, 25 parts of yellow ink, 85 parts of blue ink, 40 parts of hydroxyfluorosilicone resin, 15 parts of curing agent , 5 parts of isophorone, 5 parts of propylene glycol polyether with a molecular weight of 800-2000 and 2 parts of triammonium citrate. The curing agent is 1,4 butanediol diacrylate, the red ink is HAC-10 ink, the yellow ink is HAC-200NC ink, and the blue ink is HAC-440 ink.

[0023] The glossy ink is prepared by the following process steps: (1) 5 parts of red ink, 25 parts of yellow ink, 85 parts of blue ink, and 5 parts of isophorone are uniformly dispersed by a high-speed disperser at a speed of 800 rpm , to obtain the first mixed solution; (2) Mix 5 parts of propylene glycol polyether with a molecular weight of 800-2000, 25 parts of silver powder and 2 parts of triammonium citrate in a low-speed stirring mode (50-100 rpm), and add t...

Abstract

The invention relates to a blackish green silver ink for silk screen printing. The blackish green silver ink comprises the following components in parts by weight: 25 parts of silver powder, 5 parts of red ink, 25 parts of yellow ink, 85 parts of blue ink, 40 parts of hydroxyl fluoride silicon resin, 15 parts of curing agent, 5 parts of isophorone, 5 parts of propylene glycol polyether with 800-2000 of molecular weight, and 2 parts of ammonium citrate tribasic, wherein the curing agent is selected from diethylene glycol acrylate, 1, 4-butyl glycol acrylate or trimethylolpropane triacrylate. The blackish green silver ink provided by the invention adopts unsaturated olefinic bond type compounds with more than two acyloxy radicals in molecules as the curing agent, so that the light ink has excellent adhesion on glass and PMMA (Polymethyl Methacrylate) plastic, scrape resistance and resistance to water or solvent.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and more specifically, the invention relates to a dark green silver ink for screen printing. Background technique [0002] Decoration or marking of glass, PMMA plastic and related products plays an important role in many commercial fields. There is a huge demand such as in the construction field for indoor and outdoor applications, for example in the automotive field, in advertising, in the decorative field of household goods, etc. Large quantities of identically printed glass and glass products are usually realized with the aid of screen printing methods. In the process of printing the logo on their surface, the ink showed a strong difference between dry and wet glass surfaces. When the glass is in a wet state, the ink on the surface is extremely easy to be wiped off; especially in a humid weather environment, the decorative printing on the glass decoration material and PMMA plastic surf...
