Abstract

The invention relates to environmental-friendly type energy-saving LED (Light Emitting Diode)-UV (Ultraviolet) silk-screen printing ink. The environmental-friendly type energy-saving LED-UV silk-screen printing ink is prepared from the following raw materials in parts by weight: 51 to 58 parts of acrylate prepolymer, 15 to 19 parts of reaction monomers, 12 to 15 parts of pigment, 1 to 4 parts of dispersing agent, 0 to 5 parts of filling agent, 7 to 10 parts of photosensitizer and 0 to 1 part of polymerization inhibitor. The environmental-friendly type energy-saving LED-UV silk-screen printing ink is solidified and dried through a UV-LED light source. The environmental-friendly type energy-saving LED-UV silk-screen printing ink disclosed by the invention contains no poisonous substances, cannot generate ozone, has no odor and contains no benzenes and aromatic organic solvents, a light resisting membrane is nonflammable and cannot deform, the contact temperature is below 70 DEG C, drying is fast, solidification and cross linking can be realized within 2 to 3 seconds, the fastness of a printing product is good, and no radiation light is generated; the environmental-friendly type energy-saving LED-UV silk-screen printing ink can be used for food packaging and metal printing of a medicine packaging machine and is safer and more environmental-friendly.

Description

technical field [0001] The invention relates to the field of ink industry, in particular to an environment-friendly energy-saving LED-UV screen printing ink and a preparation method thereof. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain Fluid paste-like adhesive body. Ink is used to form graphic information in the printing process, so ink plays a very important role in printing. It directly determines the tone, color, and clarity of the image on the printed matter. Due to the wide range of uses of screen printing and low investment, screen printing is used for substrates that are difficult to print by other printing methods, so the screen printing process has developed rapidly in the past ten years. [0003] The process of screen printing for many year...
