Abstract

The invention discloses a water-based thermosetting glass printing ink and a preparation method thereof. The ink is composed of a water-based resin solution, a crosslinking agent, a dispersing agent BYK-191, an assistant, water and a pigment. The preparation method comprises the following steps: mixing part of the water-based resin solution with the dispersing agent BYK-191, assistant and pigment, and carrying out shear dispersion to obtain a slurry with the particle size of not greater than 20 micrometers; and adding the rest of water-based resin solution, assistant, crosslinking agent and water into the slurry, and sufficiently stirring. The preparation method is simple and cheap in raw materials; and the prepared water-based thermosetting glass printing ink has the characteristics of low cost, environment friendliness, favorable adhesive force with the glass substrate, favorable alcohol resistance, favorable water resistance, favorable abrasion resistance, high hardness and the like.

Description

technical field

[0001] The invention relates to a water-based thermosetting glass printing ink and a preparation method thereof, belonging to the field of glass printing inks. Background technique

[0002] With the increase in the production and application of glass screen printing ink products, the organic solvents (VOC) in the ink pollute the environment, poison the human body, and pose safety hazards caused by flammability and explosion. Water-soluble glass screen printing ink is a substitute for similar solvent-based inks. Because water is used as a diluent, the product has the characteristics of non-flammable, non-explosive, low-toxicity, less environmental pollution, and low product cost. It is environmentally friendly and resource-saving. Ink products. The key technology of water-based ink is to make the ink water-based. In the prior art, the main film-forming polymer is water-based modified, mainly to add a sufficient amount of hydrophilic carboxyl groups in the pol...

Examples

Embodiment 1

[0025] According to the following formula composition, the water-based thermosetting glass printing ink of the present invention is prepared: the water-based resin solution (about 70% of the total mass of the water-based resin solution is added first), mixed with the dispersant BYK-191, auxiliary agents and pigments, and added to the container, Obtain a slurry with a solid particle size of no more than 20 microns in the solution through high-speed shear dispersion; then add the remaining part of the aqueous resin solution, as well as additives, cross-linking agents and water to the slurry, stir well, and adjust the viscosity to the specified value, and filter through a sieve of 300 mesh or more to obtain water-based thermosetting glass screen printing ink products.

[0026] Formulas 1 to 8 are all calculated as 100 parts.
