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...
