Problems solved by technology

However, according to market demand, it is necessary to print characters on plastic substrates. The characters need to be flat printed and maintain the appearance of injection molding of the material. Therefore, it is required that the surface of the characters should not have a treatment layer.
However, if the character surface cannot have a treatment layer, then many inks used for printing characters cannot meet the wear-resisting requirements at present. Therefore, it is urgent to improve the ink used for printing characters in the prior art

Abstract

The invention relates to the technical field of ultraviolet (UV) ink, in particular to wear-resistant UV ink as well as a preparation method and an application method thereof. The wear-resistant UV ink is prepared from the following raw materials: 75-85% of color oil, 13-24% of anti-wear polishing oil and 0.5-2% of a photoinitiator. The preparation method of the wear-resistant UV ink comprises the following steps: 1, preparing in a container; 2, carrying out high speed dispersion; 3, stirring. The application method of the wear-resistant UV ink comprises the following steps: (1) carrying out annealing treatment; (2) cleaning a printing surface and a transfer printing plastic head; (3) preparing printing ink; (4) curing after printing. The wear-resistant UV ink can be used for printing characters and can enable a character layer to be wear-proof without spraying a protective ink layer onto the surfaces of the characters. The preparation method and the application method of the wear-resistant UV ink have the characteristics of being simple, low in production cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of UV inks, in particular to a wear-resistant UV ink, a preparation method and an application method thereof. Background technique [0002] With the development of science and technology, printing technology is used more and more widely, and the most important thing in printing technology is ink. In the prior art, in the process of printing products, a protective ink layer is sprayed on the surface of the printed product to protect the printing ink and make the characters of the product wear-resistant. However, according to market demand, characters need to be printed on plastic substrates, and the characters need to have a flat printing effect and maintain the appearance effect of injection molding of the material, so it is required that the surface of the characters should not have a treatment layer. However, if there is no treatment layer on the surface of the characters, many current inks for printing c...
