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
CN102295858A discloses a photocurable screen ink and its manufacturing method, but it is easy to agglomerate during storage, so the effect of long-term storage cannot be achieved
CN103666097A discloses a UV ink for screen printing and its preparation method, but its photocuring rate is slow, and the curing rate is one of the important properties of photocuring ink

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a photocurable screen printing ink and a preparation method thereof. Background technique [0002] Photocuring refers to the process in which the cured material absorbs a certain wavelength of light to undergo a crosslinking polymerization reaction after being irradiated by light, and instantly changes from a liquid state to a solid state. Photocuring printing is a printing process in which ink is dried and cured by light, and the ink containing a photosensitizer is required to cooperate with the lamp during implementation. At present, light-curable inks have covered offset printing, screen printing, inkjet, pad printing and other fields. Photocurable inks are mainly UV-curable inks, that is, UV-curable inks. Ultraviolet UV curing equipment and UV curing coating inks have undergone continuous research and development and improvement. The ultraviolet light production process w...
