PVC and PU direct printing water-based ink and preparation method thereof

Abstract

The invention provides PVC and PU direct printing water-based ink and a preparation method thereof. The direct printing water-based ink comprises the following components in parts by weight: 45-54 parts of functional resin, 12-15 parts of pigment, 5-7 parts of a filling material, 2-4 parts of a functional aid, 6-10 parts of ethanol and 18-25 parts of water. The water-based ink can be rapidly driedunder the condition of medium and low temperatures, and has good adhesion force to PVC and PU; and moreover, the water-based ink has excellent leveling property, high-speed printability, dot reproducibility and shallow board printability, has high PVC and PU adhesion fastness, is clear in multi-color chromatography layer, is safe and environmentally friendly, and has large application prospect inthe field of PVC and PU gravure direct printing.

Description

technical field [0001] The invention relates to the technical field of water-based inks, in particular to a PE and OPP film gravure surface printing water-based ink. Background technique [0002] PVC film (stretched polyvinyl chloride film) uses polyvinyl chloride as the main raw material, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. It is mainly used for surface packaging of various panels, also known as Decorative film and adhesive film are used in building materials, packaging, medicine and many other industries. They are popular, popular and widely used synthetic materials in the world today. [0003] PU film (stretched polyurethane film), is a new type of organic polymer material, known as the "fifth largest plastic", has no harm to human skin, and is widely used in clothing fabrics, medical and health, Leather and other fields. [0004] At present, solvent-based inks are mostly used for the printing of PVC films and PU fi...

AI Technical Summary

Problems solved by technology

[0004] At present, solvent-based inks are mostly used for printing PVC films and PU films, which consume a large amount of organic solvents during use, which brings great problems to environmental protection and endangers human health.

The conventional water-based ink is applied to PVC film and PU film printing. Since the printing is required to be carried out under medium and low temperature conditions, the conventional water-based ink dries slowly, which greatly affects the printing efficiency.

[0005] In summary, solvent-based inks pollute the environment and do not meet the current national requirements for environmental protection, and conventional water-based inks dry slowly under medium and low temperature conditions, which do not meet the requirements of PVC and PU film printing
