Abstract

The invention provides hydrophobic UV-LED printing ink for glass, which is prepared from the following components in parts by weight: 25 to 30 parts of organic silicon modified polyurethane acrylate, 18 to 23 parts of polyurethane acrylate, 35 to 40 parts of a n-vinyl caprolactam reactive diluent, 7 to 10 parts of a photoinitiator, 2 to 5 parts of liquid polybutadiene, 3 to 6 parts of a filler and 1 to 3 parts of an auxiliary agent, wherein the n-vinyl caprolactam is used as an active agent, the liquid polybutadiene is used as a modifier, the components are mixed to prepare the UV-LED ink with strong hydrophobicity and good adhesive force, and the UV-LED printing ink has a very good protection effect after being coated on the surface of a glass substrate and has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of UV-LED inks, and in particular relates to a hydrophobic UV-LED ink for glass and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life and the strengthening of aesthetic awareness, the requirements for the appearance of glass are getting higher and higher, and glass UV inks have emerged as the times require. The UV-LED ink used for glass in the prior art has poor hydrophobicity and adhesion when coated on the glass surface, which limits its application in the glass ink industry. Therefore, it is urgent to research and invent new products to solve the problems of general hydrophobicity, poor adhesion, and low weather resistance of UV-LED inks applied to glass. Contents of the invention [0003] In order to solve the technical problems of general hydrophobicity, poor adhesion and low weather resistance when the existing UV-LED ink is applied to glass...
