Light curing screen printing ink and preparation method thereof

Abstract

The invention discloses a light curing screen printing ink and a preparation method thereof. The light curing screen printing ink consists of the following formula components by weight: 4-6 parts of polyurethane, 10-20 parts of filler, 1-2 parts of auxiliary modifier, 2-3 parts of drier, 2-4 parts of emulsifier, 12-14 parts of absolute ethanol, 2-4 parts of silane coupling agent, 6-10 parts of polymer, 14-16 parts of talcum powder, 2-4 parts of photoinitiator, 10-12 parts of polytetrafluoroethylene, and 2-4 parts of organosilicon water-proofing agent. The technical formula of the invention is simple and easy to use. The light curing screen printing ink has the advantages of oxidation resistance, good thermal stability, high light curing rate, no toxicity, environmental protection, strong adhesion and fading preventing, so that the light curing screen printing ink has a good application prospect.

Description

Technical field [0001] The invention relates to the technical field of inks, in particular to a light-curing mesh plate ink and a preparation method thereof. Background technique [0002] Light curing refers to the process in which the cured material absorbs a certain wavelength of light and undergoes a cross-linking polymerization reaction after being irradiated with light, and instantly transforms from a liquid state to a solid state. The light-curing printing is a printing process that uses light to dry and solidify the ink, and the ink containing a photosensitizer is required to cooperate with the lamp during implementation. At present, light-curable inks have covered the fields of offset printing, silk screen, inkjet, and pad printing. UV-curable inks are mainly UV-curable inks. Ultraviolet UV curing equipment and UV curing coatings and inks have undergone continuous development and improvement. The UV production process, which uses mercury lamp irradiation as the mainstr...

Problems solved by technology

Although the traditional mercury lamp type UV curing equipment and the traditional mercury lamp type UV curing coating ink are cheap in the Chinese market, due to the high maintenance cost and large power consumption of the traditional mercury lamp type UV curing equipment, large carbon emissions and UV The rapid attenuation of the light intensity of the mercury lamp leads to frequent replacement of the ultraviolet mercury lamp, the rise of the surface temperature of the irradiated components leads to the deformation of the heat-sensitive substrate, the large volume leads to a large space occupation, a large amount of ozone is produced, and mercury pollution is large. Committed to improvement, but it has been difficult to break through the limitations of the original hardware, so the UV curing equipment used in the Chinese market for UV curing wood coatings and wood inks is mainly traditional mercury lamp type UV curing equipment
