Problems solved by technology

At present, the resins used in domestic water transfer printing inks are basically solid acrylic resins imported from abroad, which are expensive and have defects in use. Since the glass transition temperature of solid acrylic resins is 32°C, the resin particles are easy to melt and agglomerate in summer , it needs to be crushed before it can be dissolved in a solvent
And domestic thermoplastic acrylic resin mostly adopts xylene and butyl acetate as solvent, has pungent smell, is difficult to be used in printing industry; balance in strength
For cost considerations, some manufacturers use polypropylene resin instead of acrylic resin in water transfer printing ink, but there is a defect of high brittleness, and toughening agents need to be added for toughening. However, toughening agents are prone to migration, resulting in poor production Water transfer printing paper becomes brittle after a short period of storage
In addition, the production of the existing acrylic resin is a process from liquid to solid and then to liquid, which consumes more energy
[0005] Moreover, solvent-based water transfer printing inks commonly used in industries such as plastic toys, plastic sports equipment, carbon fiber sports equipment, metal bicycles, and electric vehicles are harmful to the environment and the human body; the speed and efficiency of the production process are limited to a certain extent. constraints

Abstract

The invention discloses LED-solidified water transfer printing ink and a preparation method thereof. The ink is mainly prepared from the following raw materials in parts by weight: 10-50 parts of urethane acrylate resin, 15-80 parts of epoxy acrylate resin, 5-30 parts of acrylic resin, 5-50 parts of 1,6-hexanediol diacrylate, 2-20 parts of trimethylolpropane triacrylate and 2-20 parts of photosensitive initiator. The components are sequentially added according to the parts, stirred at fixed time and constant speed and finally ground by a three-roller machine and stirred. The ink disclosed by the invention meets the customer requirements on the surface decoration of the plastic, carbon fiber and metal stainless steel toys, sports equipment, bicycles and electric vehicle cores.

Description

technical field [0001] The present invention relates to an ink, in particular to an LED-cured water transfer printing ink and a preparation method thereof, specifically to a printing ink used in plastics, carbon fiber, stainless steel, ceramics, and metal water transfer front and back labeling industries and its preparation method. Background technique [0002] Water transfer printing material refers to the printing film processed on the surface of the substrate that can transfer graphics and text as a whole. The substrate can be plastic film or water transfer printing paper. This kind of printing film is used as a graphic carrier, and its appearance should be a great progress in printing technology, because there are many products that are difficult to print directly, and with this carrier, people can use mature printing technology to print the graphic first. On a carrier that is easy to print, the graphics and text are transferred to the substrate. For example, items wit...
