Antistatic inkjet printing ink and preparation method thereof

Abstract

The invention discloses antistatic code-spurting printing ink and a preparation method thereof. The antistatic code-spurting printing ink is prepared from the following raw materials in parts by weight: 5-15 parts of acrylic resin, 65-75 parts of acetic ether, 10-20 parts of propylene glycol methyl ether acetate, 0.3-0.7 part of a fluorescent coloring agent, 3-7 parts of dyes, 0.5-1.5 parts of an antistatic agent, and 0.1-1 part of an ultraviolet light absorber. The code-spurting printing ink disclosed by the invention is simple in preparation method, is relatively low in cost, and is convenient to use; while the performance and the functions of common printing ink are kept, goods-fleeing prevention, tamper prevention and fake prevention are achieved. The code-spurting printing ink provided by the invention further has properties such as good antistatic property and good ultraviolet resistance.

Description

technical field [0001] The invention relates to the field of chemical inks, in particular to an antistatic inkjet printing ink and a preparation method thereof. Background technique [0002] For products under the high-speed production line, when performing quality traceability, printing of inkjet information is required to form product identification on the product, and then camera collection is performed for these product identifications, and the collected data is entered into the system. The existing inkjet printing inks are mainly black inks, and the information printed by black inks can be clearly recognized by the naked eye. On the material, it is difficult to 100% of the printed information to be read by camera, which greatly limits the use effect of the quality traceability system. [0003] Due to the fast volatilization speed of the solvent, the solvent-based ink can form a fast-drying coating film on any material, which is suitable for the requirements of high-spe...

Problems solved by technology

However, the fluorescent substances used in previous solvent-based fluorescent inks are invisible under visible light, and it is difficult to balance color recognition and light-excited luminescence; in addition, fluorescent inks in water-based systems can only be applied to piezoelectric inkjet printing systems that are printed on demand , not suitable for continuous printing piezoelectric printing system, due to the slow evaporation of water, the general printing materials are permeable materials (paper products and fabrics), in non-permeable materials (metal, plastic , coating materials, varnish paper, etc.) are not easy to dry, and the ink surface tension of the water-based system is large, which affects the adhesion and other properties of the dried coating film

[0004] In order to reduce the harm caused by static electricity, at present, people usually add pigments and fillers to the ink to suppress the generation of static charge and promote the leakage of static charge, thereby reducing the surface resistance of the film-forming material to a certain extent and enhancing the coating film. Antistatic performance, however, due to the structure of the coating material itself and the fact that pigments and fillers are generally small molecules, the antistatic effect produced by this method is not very ideal. How to develop an antistatic effect that is good and durable? Electrostatic additives, and used in inks, are a problem faced by workers in all ink fields
