The application discloses an environmentally-friendly soft type yoga mat special silk-
screen printing ink and a preparation method thereof, and belongs to the technical field of silk-
screen printing inks. The ink comprises the following components in parts by weight: 30-50 parts of main body resin, 5-15 parts of environmentally-friendly
pigment, 25-45 parts of environmentally-friendly composite
solvent, 1-5 parts of adhesion
promoter, 0.5-2 parts of rheological additive, 0.5-2 parts of scratch-resistant additive, and 2-8 parts of environmentally-friendly non-ortho phenyl
plasticizer. The ink is extremely environmentally-friendly, meets international export standards, and is free of
phthalate plasticizers,
benzophenone solvents and heavy
metal pigments in the whole process. Instead, the ink uses
citric acid ester non-ortho phenyl plasticizers,
benzene-free and
ketone-free composite solvents and heavy
metal-free organic pigments. The VOC content is far lower than the national
limit value, the irritating
odor is eliminated, and
phthalate controlled substances are not detected. The ink meets the EU REACH regulation appendix XVII 51 / 52 and the EN71-3 toy safety standard, and completely solves the problem of limited export of traditional inks.
