Embodiment Construction

[0023] The environment-friendly ultraviolet light curing iron printing ink mainly includes prepolymer, monomer, dispersant, initiator, pigment and auxiliary agent. The specific raw material components (parts by weight) are: acrylic prepolymer 60%, acrylic acid 12% monomer, 8% initiator, 14% pigment, 6% dispersant and other additives.

[0024] Among them, the acrylic prepolymer is epoxy acrylate and polyester acrylate; the acrylic monomer is tripropylene glycol diacrylate; the dispersant is the polymer pigment dispersant K-SPERSE which is suitable for UV-curable ink Pigment dispersant; polymer pigment dispersant K-SPERSE is commercially available, such as this type of product produced and sold by King’s Industries in the United States; pigments are titanium dioxide, permanent yellow, phthalocyanine blue, carbon black and golden red, etc.; As the agent, 1-hydroxy-cyclohexyl phenone and 2-methyl (4-methylsulfonylphenyl)-2-morpholine-1-acetone and the like are used.

Abstract

This invention discloses environmentally friendly UV-curing tin plate ink, which comprises: acrylic acid prepolymer 50-70 wt.%, acrylic acid monomer 10-15 wt.%, initiator 5-10 wt.%, pigment 10-25 wt.%, dispersant and other additives 5-10 wt.%. The UV-curing tin plate ink is a color printing ink used on metal and cured by UV. The UV-curing tin plate ink has such advantages as low energy consumption, rapid curing, no VOC discharge, high efficiency, high safety and no pollution.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly ultraviolet light curing iron printing ink. Background technique [0002] At present, the curing of ordinary iron printing ink in China is heating and baking, which requires the use of a large amount of natural gas, petroleum liquefied gas, or electric energy. According to a conservative estimate by the China Metal Packaging Association, there are more than 400 iron printing production lines in China, which consume at least 50 million cubic meters of petroleum liquefied gas every year. Baking and curing needs to be installed in an oven for 15-20 minutes. When the ink is not dry, multi-color printing is very prone to color mixing. This also makes general iron printing equipment can only print two colors at the same time at most, and some even monochrome. There are great restrictions on production efficiency; the post-drying oven of the iron printing produ...
