Abstract

The invention belongs to the technical field of preparation of cured ink, and particularly relates to self-cleaning UV (ultraviolet) light-cured ink not easy to yellow and a preparation method thereof, and the self-cleaning UV light-cured ink comprises the following raw materials in parts by weight: 50-200 parts of UV epoxy resin and 20-80 parts of polyurethane UV resin. According to the invention, the anti-yellowing capability of the material is improved through the arrangement of the anti-yellowing auxiliary agent; therefore, yellowing after long-time placement is avoided, and the normal useof the UV light-cured ink is not influenced; the waterproof agent is arranged, so that the waterproof capability of the material is improved; through the cooperation of an emulsifier, an adhesion promoter and a leveling agent, the material can be uniformly mixed after being prepared; compared with the prior art, the mixing effect is better, so that the situation that normal use is affected due todifferent fineness and viscosity during use is avoided; cleaning can be easier and more convenient through the use of the polyurethane UV resin, and cleaning inconvenience caused by attachment to a glass material is avoided.

Description

technical field

[0001] The invention relates to the technical field of curing ink preparation, in particular to a non-yellowing self-cleaning UV light curing ink and a preparation method thereof. Background technique

[0002] Glass products continue to develop in the process of modern industry. The application of glass materials is more in-depth and extensive. Home decoration glass and electronic glass have more performance requirements for matching inks. The inks developed for glass materials mainly include water-based inks, solvent-based inks and UV light-curable inks. The heat treatment process of water-based ink is too long, and the VOC release of solvent-based ink directly limits the application expansion of glass materials;

[0003] 1. When in use, UV light-curable inks are prone to yellowing when placed for a long time, which affects the normal use of UV light-curable inks;

[0004] 2. The existing UV photocurable ink has poor waterproof effect, and it is easy to us...
