Abstract

The invention provides a special silica gel base material 3D structure decorating part and a preparation process thereof, and relates to the technical field of silica gel material processing. The special silica gel base material 3D structure decorating part comprises a PET membrane, a TPU protective film is attached to the bottom surface of the PET membrane, a TPU sheet is attached to the bottom surface of the TPU protective film, and a UV transfer printing layer is attached to the bottom surface of the TPU sheet; a vacuum coating layer is attached to the bottom face of the UV transfer printing layer, an elastic ink layer is attached to the bottom face of the vacuum coating layer, a treating agent layer is attached to the bottom face of the elastic ink layer, a silica gel ink layer is attached to the bottom face of the treating agent layer, and a release protection film is attached to the bottom face of the silica gel ink layer. The decorative layer adopting TPU as the film base has good elasticity and flexibility, the silica gel ink on the bottom layer can be well bonded with a silica gel material, the flexibility and touch feeling are guaranteed, TPU is adopted as a base materialfor UV transfer printing, and a good transfer printing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of silica gel material processing, in particular to a special silica gel substrate 3D structural decoration and a preparation process thereof. Background technique [0002] With the continuous development and progress of 3C devices, mobile devices, portable devices, and wearable devices, these devices have already penetrated into the daily life of consumers, and many producers and sellers have entered the market one after another. , these devices must not only be powerful and complete in function, but must also be beautiful and unique in appearance. Therefore, soft materials such as silicone rubber have begun to be widely used in these devices as peripheral accessories, outer structure protection and protection of these devices. decorative layer. Silicone material itself has many characteristics, which make silica gel very suitable as a decorative layer or protective layer on the surface of articles in term...
