Problems solved by technology

Using the above process, it is necessary to die-cut the explosion-proof membrane material into sheets, and then perform UV transfer printing, electroplating and printing. The yield and efficiency of the whole process are extremely low. At the same time, the anti-yellowing effect of the material is not considered due to the yellowing effect. Poor, there is a problem of easy yellowing

Abstract

An anti-yellowing colorful explosion-proof membrane relates to the technical field of printed explosion-proof membranes, and comprises a base material layer, wherein the base material layer is prepared from an optically-grade PET membrane or a PC membrane or a PMMA membrane, the bottom surface of the base material layer is provided with a printable hardening layer in a spin-coating manner, the printable hardening layer is subjected to spin-coating and rolling-pressing by a roller with the peripheral surface provided with textures, and a dyeing aid is added on the printable hardening layer, sothat the wire drawing and texture as well as color change can be achieved, the top surface of the base material layer is coated with an adhesive layer, an ultraviolet absorber and a stabilizing agentare added in the adhesive layer, and the top surface of the adhesive layer is compounded with a protective membrane layer. The invention relates to the anti-yellowing colorful explosion-proof membranewhich can be applied in the back cover of a 5G mobile phone; and the membrane can be directly silk-screened on the surface, operation procedures, such as slicing and UV transferring, are omitted, theproduction efficiency is high, and the anti-yellowing effect is good.

Description

technical field [0001] The invention relates to the technical field of printed explosion-proof membranes, in particular to an anti-yellowing colorful explosion-proof membrane. Background technique [0002] With the development of communication technology, the era of 5G is coming. In the original electronic products, the metal mobile phone back cover can no longer meet the existing wireless communication technology due to the problem of blocking the 5G signal, and it is lightweight, thin, and diverse in appearance. The demand for transformation is also increasing. [0003] At present, more and more wireless communication devices such as mobile phones tend to use plastic or glass for the production of the shell or back cover, and use the IMD injection molding process to complete. Specifically, it is necessary to prepare the plastic into the required special-shaped shell material or glass CNC processing, silk screen printing, electroplating and other treatments on the surface ...
