Problems solved by technology

[0002] With the improvement of people's living standards, daily necessities are rich and colorful. For example, many touch buttons were originally made of hard materials, which have a bad hand feel. Now many soft touch buttons are mostly made of TPU (thermoplastic polyurethane) material, and most football leather materials are also TPU. Materials, in the previous printing process, it was necessary to use a variety of organic solvents to treat the surface of the material, and then add a curing agent to the ink for printing, in order to achieve the performance requirements of bright light, stamping resistance, wear resistance, impact resistance, etc., which will not only pollute Environment, waste of resources, and inconvenient operation of adding hardener

Abstract

The invention discloses curing-agent-free treatment-free silk-screen printing ink for a thermoplastic polyurethane (TPU) material. The ink comprises the following components in percentage by weight: 40-50% of PU resin, 30-45% of ketone solvent, 20-25% of ester solvent and 1-2 parts of additive. The ink disclosed by the invention is environmentally-friendly silk-screen printing ink free of surfacetreatment and a curing agent, has good printing property and strong adhesion force on the printed material, and can reach the functional requirements of wear resistance, striking resistance, impact resistance and the like.

Description

technical field [0001] The invention relates to an ink, especially a screen printing ink for thermoplastic polyurethane materials without adding a curing agent and without surface treatment. Background technique [0002] With the improvement of people's living standards, daily necessities are rich and colorful. For example, many touch buttons were originally made of hard materials, which have a bad hand feel. Now many soft touch buttons are mostly made of TPU (thermoplastic polyurethane) material, and most football leather materials are also TPU. Materials, in the previous printing process, it was necessary to use a variety of organic solvents to treat the surface of the material, and then add a curing agent to the ink for printing, in order to achieve the performance requirements of bright light, stamping resistance, wear resistance, impact resistance, etc., which will not only pollute The environment will waste resources, and the hardening agent is inconvenient to operate....
