Abstract

The invention provides waterborne PET silk screen ink and a preparation method thereof. The waterborne PET silk screen ink disclosed by the invention is prepared from the following raw material ingredients in parts by weight: 50 to 80 parts of polyester resin compound fluid, 10 to 20 parts of cosolvent, 0.1 to 0.5 part of dispersing agent, 0.5 to 1 part of defoaming agent, 0.5 to 1 part of leveling agent, 0.5 to 1 part of acid-base balance agent, 2 to 8 parts of slow dry solvent, 8 to 35 parts of pigment and the balance of deionized water. The preparation method disclosed by the invention hasthe advantage of simple technology, the preparation raw materials don't contain organic solvent, water is utilized as a solvent, and the prepared waterborne PET silk screen ink has the advantages of good adhesion force to a base material, high glossiness, good transparency, excellent leveling property, good bearing performance to pigments and dyes, good adhesion force to varieties of plastic films, good water resistance, UV resistance and alcohol resistance, small odor and convenience in construction.

Description

technical field [0001] The invention belongs to the technical field of ink, and relates to a water-based PET screen printing ink and a preparation method thereof. Background technique [0002] PET screen printing ink is an ink produced for PET materials (polyethylene terephthalate), PET self-adhesive labels, and some acrylic material membrane switches. It is printed on the surface of the material by screen printing and has excellent performance. Excellent printing workability and post-processing. At present, the PET inks on the market are basically oil-based inks, which contain a large amount of organic solvents, which are harmful to the environment and the human body. In recent years, due to the control of organic solvents in the market, people tend to replace oil-based inks with environmentally friendly inks , to reduce environmental pollution and harm to the human body, therefore, water-based ink has become a market development trend. [0003] Water-based ink is a water...
