AI Technical Summary

Technical Problem

The isolation paper materials used in traditional printing processes lead to high production costs, waste of resources, environmental pollution and quality problems of printing surfaces, especially the matte effect changes caused by plasticizer migration and impairment of printing pattern integrity.

Method used

An environmentally friendly water-based skin-feeling cover slurry has been developed, including PU matte lotion, water, dispersant, moisturizer, silicone oil and emulsifier. Through specific ratios and preparation methods, a cover slurry without isolation paper is formed, using Crosslinking additives enhance viscosity and stability.

Benefits of technology

It achieves lightning-free, high matteness, soft feel, anti-moisture, durable and non-returning effects, reduces the use of organic solvents, reduces production costs and environmental pollution, and improves production efficiency.

Abstract

The invention discloses an environment-friendly water-based skin-touch covering paste with a release-paper-free effect as well as a preparation method and application thereof, and belongs to the technical field of printing and dyeing. The environment-friendly water-based skin-touch covering slurry with the release paper-free effect is prepared from the following components in parts by weight: 60 to 73 parts of PU matte emulsion, 2 to 7 parts of water, 0.1 to 1 part of dispersing agent, 5 to 8 parts of humectant, 17 to 23 parts of silicone oil, 0.5 to 2 parts of emulsifying agent and 1 to 5 parts of thickening agent. After covering, the environment-friendly water-based skin-touch covering paste with the release paper-free effect is free of lightning, high in matt degree, good in fastness, soft in hand feeling and resistant to moisture absorption, and the processes of printing mucilage, thick plates and the like can be performed after covering without delamination. The traditional requirement of using isolation paper is broken through, the covering surface is very dry and comfortable, after-tack is avoided, light reflection is avoided after long time, and the skin feeling is strong.
