Water-resistant, scratch-resistant and ultraviolet-cured ink for glass

Abstract

The invention relates to the field of ink and particularly relates to water-resistant, scratch-resistant and ultraviolet-cured ink for glass. The water-resistant, scratch-resistant and ultraviolet-cured ink for glass is prepared from the following raw materials in percentage by mass: 30-45% of mixture of aliphatic polyurethane acrylate oligomer and carboxylic acid modified polyester acrylate, 5-12% of initiator, 1-3% of surface auxiliaries, 5-10% of cosolvent, 10-20% of activated thinner, 1-2% of nano-silver antibacterial agent and 10-30% of inert solvent. The water-resistant, scratch-resistant and ultraviolet-cured ink has an antibacterial function while having good water resistance and scratch resistance, meanwhile, cannot affect the performance indexes of a coating material, and has relatively high salt mist resistance, aging resistance, adhesive power and cold / hot impact resistance.

Description

technical field

[0001] The invention relates to the field of inks, in particular to a water-resistant and scratch-resistant UV-curable ink for glass. Background technique

[0002] Since the advent of UV-curable coatings, it has the characteristics of 5E, namely Efficient, Enabling, Economical, Energy Saying, and Environmental-friendly. In the prior art, UV-curable coatings have been widely used in fields closely related to life to beautify and protect objects.

[0003] As a major category of printing consumables, compared with plastics, glass has the advantages of high transparency, good mechanical strength, and good weather resistance. At the same time, with the rise of international crude oil prices, the production cost of glass is also lower than that of plastics. However, due to the low surface energy of glass, the ink is not easy to adhere, which has limited its application in the printing industry for a long time.
