Problems solved by technology

In the future screen printing ink market, traditional solvent-based inks will be gradually eliminated because they are harmful to the human body, volatile solvents cause air pollution, and do not comply with the national environmental protection policy of energy conservation and emission reduction. Water-based environmental protection inks for screen printing will replace them
[0003] Leather ink is also called nylon ink in the market. The nylon ink currently on the market is mainly made of polyurethane resin liquid dissolved in cyclohexanone. Regulations are getting stricter and restricted in many areas
[0004] Compared with traditional solvent-based nylon inks, water-based nylon inks have defects such as slow drying, poor washability, and poor adhesion compared with traditional solvent-based nylon inks, which cannot meet market requirements. Therefore, the traditional solvent-based inks in the current screen printing ink market Nylon ink still accounts for a large proportion

Abstract

The invention discloses environmentally friendly leather screen water-based ink and a preparation method thereof. The environmentally friendly leather screen water-based ink is prepared from 40-60 parts by weight of an aqueous polyurethane emulsion, 35-55 parts by weight of a water-based acrylic emulsion, 15-25 parts by weight of water, 2-4 parts by weight of a wear-resistant slipping agent, 0.8-1.2 parts by weight of sodium alginate, 0.5-1 part by weight of an antifoaming agent, 0.5-1 part by weight of a leveling agent, 0.3-0.6 parts by weight of a wetting agent, 0.3-0.6 parts by weight of adispersant and 5-10 parts by weight of a pigment. Through a large number of experimental researches, the components and ratios of the water-based ink are selected. The environmentally friendly leatherscreen water-based ink is easy to use and store, has no solvent residues, has no pollution to the leather and is health and safe for the human body. The printed product has good gloss, wear resistance, excellent adhesion and coloring power, good hydrophobicity, water washing resistance and excellent use performances.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environmentally friendly leather screen water-based ink and a preparation process thereof. Background technique [0002] With the development of society, under the dual pressure of the energy crisis and the worldwide anti-environmental pollution movement, the solvent-free screen printing ink has become a trend. In the future screen printing ink market, traditional solvent-based inks will be gradually eliminated because they are harmful to the human body and cause air pollution due to volatile solvents, which do not comply with the national environmental protection policy of energy conservation and emission reduction. Water-based environmental protection inks for screen printing will replace them. [0003] Leather ink is also called nylon ink in the market. The nylon ink currently on the market is mainly made of polyurethane resin liquid dissolved in cyclohexanone. Regulations ar...
