Abstract

The invention provides an environmentally-friendly aqueous leather stamp-pad ink with environmentally-friendly and safe property and wide application, and a preparation method thereof. The environmentally-friendly aqueous leather stamp-pad ink comprises an organic solvent, resin, a surfactant, a pigment dispersant, an adhesion promoter, a pigment and water according to a mass ratio of (15-28):(30-40):(1-2):(2-5):(0.5-1):(10-15):(30-40). The environmentally-friendly aqueous leather stamp-pad ink has good adhesion to leather, can be transfer-printed at normal temperature to form a soft imprinted film with bright color on the leather, and the imprinted film has the characteristic of acid and alkali resistance, water washing resistance, oil resistance, good weatherability and no color fading. The environmentally-friendly aqueous leather stamp-pad ink is safe and environmentally-friendly, meets safety detection standards of European Union SGS EN71-10 of textiles, accords with the limit of harmful substances in Safety of Toys - Part 10: Organic Chemical Compounds - Sample Preparation and Extraction, and has good market prospect.

Description

technical field [0001] The invention relates to a water-based printing oil and a preparation method thereof, in particular to an environment-friendly leather water-based printing oil and a preparation method thereof. Background technique [0002] With the improvement of people's life, leather products are more and more used in clothing, handbags, handicrafts, accessories, and decorative creative designs. The processing technology of leather is more and more advanced, and the color of leather is more and more gorgeous. But most importantly, people's awareness of environmental protection is increasingly being placed in an important position. [0003] The way of marking on leather is currently using solvent-based ink. These inks are composed of volatile solvents, resins, dyes or pigments. Most of them contain unenvironmentally friendly and non-degradable solvents, additives, and surfactants to complete. The price is high and the smell is bad. The most important thing is th...
