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 co

Example Embodiment

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the implementation of the present invention. Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] The following is the first preferred embodiment of the present invention. A PVC or PU direct printing water-based ink includes the following components by weight:

[0024]

[0025] Further, the functional resin is synthesized from modified copolymerized polyurethane and acrylic at a low temperature of 70-80°C. The functional resin polymerizes under normal pressure, has...

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...
