Abstract

Disclosed are components of a ultraviolet ray solidified printing ink for digital spraying machine and its preparing method. The UV solidified printing ink comprises of prepolymer, active monomer, color, photoinitiator, dispersant and surface active agent, which are mixed by a certain ratio, through grinded ( instantaneously ) and stirring to produce the product. The printing ink doesn't contain organic solvent, for environmental protection, it can be solidified in grinded ( instantaneously ) under the ultraviolet ray for satisfying high speed requirement, as well as print on glass steel,PE and PP film, eramic tile and film and other material, with wide application and bright future.

Description

technical field [0001] The invention relates to an ultraviolet (UV) curing ink and a preparation method thereof, in particular to a UV curing ink applied on a digital flat-panel inkjet printer and a preparation method thereof. Background technique [0002] In recent years, large-scale inkjet printers have developed rapidly with the development of the computer industry. According to the working principle of the nozzle, inkjet printers can be divided into thermal foam type and piezoelectric crystal type. Thermal foam nozzles are mainly used in inkjet printers produced by Hewlett-Packard, Mimaki and other companies. These machines mainly use water-based inks, and the colorants are usually dyes; , Shenyang Airship and other companies' inkjet printers, this type of nozzle mainly uses solvent-based inks, and the colorant is organic pigments. As the requirements for environmental protection are getting higher and higher, nozzles using UV-curable inks have begun to appear and have ...
