Abstract

The invention relates to the technical field of ink, and in particular, relates to TPE ink and a preparation process thereof; the TPE ink comprises a main agent and an auxiliary agent; the main agentcomprises the following components in parts by weight: 20 to 40 parts of SBS resin, 15 to 25 parts of white oil, 6 to 12 parts of a pigment, 15 to 25 parts of ink thinner, 10 to 20 parts of a compatilizer, 4 to 8 parts of a dispersing agent, 8 to 12 parts of an anti-blocking agent; and the auxiliary agent comprises the following components in parts by weight: 8 to 10 parts of a surface treating agent. By adopting the technical scheme, after the surface of the TPE is treated by the surface treating agent, the surface adhesive force of the TPE is enhanced, then the main agent is sprayed on the surface of the TPE, and the adhesive force of other components on the surface of the TPE is further improved by the anti-blocking agent in the main agent. And under the action of the compatilizer and the dispersing agent, the ink can be uniformly attached to the surface of the TPE and is kept relatively stable. Therefore, the problem that the surface of TPE is not easy to print is solved. Comparedwith the prior art, the ink is sprayed, the adhesive force of the ink on the surface of the TPE is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a TPE ink and a preparation process thereof. Background technique [0002] Because TPE materials have good molding properties, material stability, and anti-ultraviolet variation properties, which are superior to other soft rubber materials, TPE materials are increasingly used in various electronic products. Due to the high stability of the TPE material, the surface tension of the material is very weak. [0003] It is difficult to carry out appearance treatment on TPE materials, such as printing LOGO, printing colors, etc., and the coating is easy to peel off. In order to meet the needs of the rich and colorful commodity market, it is necessary to solve the problem of TPE material printing. [0004] In the prior art, for example, in the Chinese invention patent with application publication number CN104044378A, a printing method of TPE material is disclosed. The present invention use...
