Example Embodiment
[0042] Example 1:
[0043] The environmentally friendly UV light-curable ink is prepared from the following raw materials, and each component is calculated in parts by weight:
[0045] (1) Add polyether polyol aliphatic urethane acrylate, dipropylene glycol diacrylate, polyester acrylate, pentaerythritol triacrylate, 819, 1173 into the tinplate in turn, in a constant temperature water bath at 90-96 °C, with high speed The dispersing machine disperses and stirs for full dissolution, lasting 0.5-1 hour;
[0046](2) Then add Tego-Foamex N, DC-57, Tego-655, cool down to 70°C, and continue stirring for 0.5-1 hour;
[0050] The preparation method is the same as in Example 1.

Abstract
The invention belongs to the field of ultraviolet curing ink, and relates to UV gravure white ink for a food packaging BOPP film, and a preparation method thereof. The UV gravure white ink is preparedfrom the following raw materials by weight: 8 to 15 parts of polyether polyol aliphatic polyurethane acrylate, 8 to 15 parts of polyester acrylate, 30 to 40 parts of dipropylene glycol diacrylate, 2to 6 parts of pentaerythritol triacrylate, 1 to 3 parts of 819, 1 to 3 parts of 1173, 0.3 to 0.8 part of Tego-Foamex N, 0.8 to 1.5 parts of DC-57, 0.3 to 0.8 part of Tego-655, 3-8 parts of talcum powder, 3-8 parts of light calcium carbonate, and 15-30 parts of titanium dioxide. The ink is applied to food packaging BOPP films, the printing speed can reach 200 m/min or above while the low cost is guaranteed, and the ink is good in adhesive force and resistant to abrasion and is environment-friendly UV photocuring ink.
Description
technical field [0001] The invention belongs to the field of ultraviolet curing inks, and relates to a UV gravure white ink for food packaging BOPP films and a preparation method thereof. Background technique [0002] At present, 90% of enterprises in my country's film and flexible packaging industry use gravure printing technology, and most of them use solvent-based inks. However, this type of ink has been "excluded" and restricted under the increasingly severe environmental protection situation. In some economically developed areas, it is even banned. Especially in the past two years, my country's central and local provincial and municipal environmental protection departments have introduced a series of policies and regulations to reduce VOCs. Flexible packaging companies have to install organic waste gas treatment equipment at the end of production. Terminal treatment technology has developed rapidly in recent years, but cannot Really solve the problem from the source, so ...
