Technical Field

The invention relates to the technical field of printing ink, in particular to temperature-resistant water-based flexographic printing ink.

Background

The polyethylene breathable film and the non-breathable film used in the sanitary material need high-temperature sealing during packaging, and the high temperature of the sealing can lead ink on the packaging to be melted, thus destroying the attractiveness of the packaging; in addition, the water-based ink in this case mostly uses ethanol as a solvent, and the ink has a high VOC in use.

The present invention therefore provides a new ink formulation to solve the above problems.

Disclosure of Invention

The invention mainly aims to provide a temperature-resistant water-based flexographic ink which can prevent the ink from melting after being subjected to high temperature.

The invention realizes the purpose through the following technical scheme:

the temperature-resistant water-based flexographic printing ink comprises the following components in percentage by mass: 45-55 wt% of S-70 type water-based resin, 12-18 wt% of 3021 type water-based resin, 1.7-6 wt% of an auxiliary agent, 0.5-3 wt% of silicone oil, 2-6 wt% of monoethanolamine, 12-17 wt% of a pigment and the balance of deionized water.

Specifically, the auxiliary agent comprises an antifoaming agent accounting for 0.2-1 wt% of the total mass percentage.

Specifically, the auxiliary agent comprises a dispersing agent accounting for 1-3 wt% of the total mass percentage.

Specifically, the auxiliary agent comprises a leveling agent accounting for 0.5-2 wt% of the total mass percentage.

Compared with the prior art, the temperature-resistant water-based flexographic ink has the beneficial effects that:

the ink disclosed by the invention can resist high temperature, and the components do not contain ethanol and have no VOC (volatile organic compounds) emission.

Detailed Description

The temperature-resistant water-based flexographic printing ink comprises the following components in percentage by mass: 45-55 wt% of S-70 type water-based resin, 12-18 wt% of 3021 type water-based resin, 1.7-6 wt% of an auxiliary agent, 0.5-3 wt% of silicone oil, 2-6 wt% of monoethanolamine, 12-17 wt% of a pigment and the balance of deionized water.

The water-based resin A mentioned in the invention is S-70 water-based resin provided by Shanghai Kaochuan trade company, the water-based resin B is 3021 water-based resin provided by Liandonggang Bailey new material development company, the defoaming agent is BYK-022 defoaming agent provided by Kunshan dai fine chemical technology company, the dispersing agent is TEGO 760W dispersing agent provided by Songxin International trade company, the flatting agent is OT-75 flatting agent provided by Yingkel trade company, and the pigment can be pigment with various colors on the market.
