Abstract

The invention discloses boiling-resistant UV (Ultraviolet) curing jet-ink for a non-absorbent substrate and a preparation method of the jet-ink. The UV curing jet-ink consists of the following components in percentage by weight: 60-75 percent of reactive diluent, 15-25 percent of polyester acrylate oligomer, 2-6 percent of nanometer pigment paste, 0.5-3 percent of polysilazane and 5-10 percent of photoinitiator. The UV curing jet-ink is uniformly dispersed, and the adhesion force of the jet-ink can reach 100 percent and the hardness is larger than 3H after the non-absorbent substrate is cured; the jet-ink is not cracked after baking at 200 DEG C for 1 hour, and the performances are not remarkably weakened after the jet-ink is soaked in cold water or boiled in water at 80 DEG C for 1 hour. The boiling-resistant UV curing jet-ink is suitable for multiple non-absorbent substrates, has excellent water resistance, simple in process and environment-friendly, and the substrate does not need to be pretreated.

Description

technical field [0001] The invention relates to a UV light-curable inkjet ink, in particular to a water-resistant UV light-curable inkjet ink for non-absorbing substrates and a preparation method thereof, belonging to the technical field of inkjet. Background technique [0002] UV light-curable inkjet ink has the advantages of zero VOC emissions, low energy consumption, and environmental protection. It is suitable for a variety of substrates. The inkjet ink is not dry before UV light, and there will be no clogging of the nozzle due to the volatilization and drying of the ink solvent. Research and application are receiving more and more attention. At present, light-curing inkjet can form durable cured films on many substrates, such as plastics, paper, and even ceramics, forming a mature production process and process. However, for non-absorbent substrates, there is currently no relatively mature technology to solve the problem of difficult combination of cured film adhesion,...
