Problems solved by technology

[0005] However, due to its high crosslinking density, general UV inks do not have defects such as recoatability and high hardness, and post-processing is limited.
Therefore, the existing technology needs to be perfected and developed.

Abstract

The invention relates to the field of ink, specifically to a special UV transfer printing adhesive for transfer printing of nanometer fine lines on 3.5D high-tensile PC + PMMA composite boards and screen printing color ink of the 3.5D high-tensile PC + PMMA composite boards and an application of the special UV transfer printing adhesive. The objective of the invention is to provide a high-tensileUV transfer printing adhesive used for 3.5D and an application thereof. The high-tensile UV transfer printing adhesive is a UV light-cured transfer printing adhesive which is UV light-cured, easy to recoat, excellent in toughness, high in tensile strength and good in resistance, and aims to solve the problem that a conventional UV transfer printing adhesive is incapable of being used for the high-tensile requirement of post-processing of 3.5D due to low tensile strength. The UV transfer printing adhesive provided by the invention has a viscosity of 300-600 CPS at a room temperature of 25 DEG C, is high in adhesive force and excellent in flexibility, can realize transfer printing of various nanometer fine lines according to the requirements of customers, and gives people beautiful texture and rich visual effects.

Description

technical field [0001] The invention relates to the field of inks, in particular to a special UV transfer glue for transferring and printing nanometer fine lines on 3.5D high-stretch PC+PMMA composite plates and silk-screen color inks and its application. Background technique [0002] At present, with the rapid development of the mobile phone manufacturing industry and continuous upgrading, customers' requirements for products are also constantly improving. Cover plate requirements have been increased from the previous 2.0D→2.5D→3.0D→3.5D tensile strength. At the same time, the requirements for ink column products are getting higher and higher, and the difficulty factor is getting bigger and bigger. Usually the cover plate construction process: raw materials (PC+PMMA)→(or raw material+coating, or offset printing transparent color)→UV transfer printing glue (transfer fine nano-texture)→screen printing color ink→stretching processing molding→packaging. The main purpose of UV ...
