Red brown silver light ink for silk screen printing

Abstract

The invention relates to a red brown silver light ink for silk screen printing. The red brown silver light ink comprises the following components in parts by weight: 25 parts of silver powder, 75 parts of transparent red ink, 15 parts of transparent yellow ink, 20 parts of transparent blue ink, 30 parts of melamino-formaldehyde resin, 20 parts of a curing agent, 5 parts of isophorone, 5 parts of polytetrahydrofuran diol with 800-1000 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 red brown silver light 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 red-brown-silver bright 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 plasti...

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
