Abstract

The invention discloses and provides LED photocured inkjet ink suitable for high-speed ink jetting, which does not evaporate a solvent, can reduce energy consumption, can reduce environmental pollution and is suitable for cold light source LEDs. The inkjet ink comprises the following components in parts by weight: 1-10 parts of a nanoscale pigment, 2-5 parts of an ultraviolet light absorber, 1-10 parts of a super dispersion agent, 2-10 parts of a quick initiator, 2-20 parts of a macromolecular prepolymer, 0.1-2 parts of a wetting and leveling agent, 0.1-1 part of a defoaming agent, 0.1-10 parts of an adhesion promoter, 5-10 parts of a combined monomer and 30-70 parts of a UV active diluent. According to the formula of the ink, the viscosity of the ink can be reduced, a spray head of a printer cannot be blocked, ultraviolet lights can be absorbed, curing energy can reach 130 mj / cm<2>, the curing speed of the ink can be increased, the curing time can be controlled within 5-20 seconds, and meanwhile, the transfer rate of printing pattern is improved; the LED photocured inkjet ink has long-acting antioxidative and anti-yellowing performances, high luster sensation and marresistance.

Description

technical field [0001] The invention relates to an LED photocurable inkjet ink suitable for high-speed inkjet. Background technique [0002] UV inkjet printing is one of the fastest-growing technologies in the field of UV technology. UV inkjet printing has made remarkable achievements in recent years. Its output value has increased from US$3.9 billion in 2008 to US$6.7 billion in 2012, and is expected to It grew to $15.9 billion in 2018. UV inkjet technology has established its own user base in the printing and packaging markets. In 2013, the consumption of inks and coatings in this market was 60,000 tons and 82,000 tons respectively. Although there has been a significant increase, it is still insignificant compared with the annual ink consumption of 3.2 million tons in the entire printing and packaging market. . Smithers Spino released a report "2018 UV Inkjet Printing Market Forecast", which shows that UV inkjet printing will develop rapidly on a global scale. Its mark...
