Problems solved by technology

Using the above process, the explosion-proof membrane material needs to be die-cut into sheets, and then UV transfer printing, electroplating and printing are carried out. The yield and efficiency of the whole process are extremely low. In the processing process, sheet-to-sheet production is required, and the process

Embodiment 1

[0021] A colorful explosion-proof film, including a TPU layer optical film with a thickness of 45 μm, coated with a self-aligned liquid crystal colorful layer and a PS reflective coating layer on the upper and lower surfaces, and the thickness of the colorful layer or PS reflective coating is 3 μm respectively , 3μm, the light transmittance of the colorful layer and the PS reflective coating are 65% and 85% respectively, and the specific band reflectances of the two are 80% and 90% respectively, which are used to show different colors; the upper surface of the colorful layer is coated There is a PET release film with a thickness of 35 μm, and a hot-melt film is coated between the PET release film and the colorful layer. The thickness of the hot-melt film is 25 μm, and the peeling force is 50 N / in. At the same time, between the optical film and the reflective coating layer The transfer texture is set between them, and the transfer texture is UV transfer pattern to further improv...

Embodiment 2

[0023] A colorful explosion-proof film, including a PET layer optical film with a thickness of 40 μm, coated with a self-aligned liquid crystal colorful layer and a PS reflective coating layer on the upper and lower surfaces, and the thickness of the colorful layer or PS reflective coating is 2 μm respectively , 3μm, the light transmittance of the colorful layer and the PS reflective coating are 60% and 80% respectively, and the specific band reflectances of the two are 75% and 90% respectively, which are used to show different colors; the upper surface of the colorful layer is coated There is a PET release film with a thickness of 30 μm, and an OCA optical film is coated between the PET release film and the colorful layer. The thickness of the OCA optical film is 20 μm, and the peeling force is 45 N / in. The transfer texture is set between them. The transfer texture is UV transfer pattern to further improve the absorption effect on ultraviolet rays. The PS reflective coating la...

Abstract

The invention provides a colorful explosion-proof membrane which comprises a PET or TPU layer optical membrane, and the upper surface and the lower surface of the PET or TPU layer optical membrane arecoated with a liquid crystal colorful layer and a PS reflective coating layer which are arranged in a self-orientation mode respectively. An OCA optical film, a hot melt film or a UV tackifier layeris coated between a PET release film and a colorful layer, meanwhile, transfer printing textures are arranged between the optical film and a reflection coating layer, the PS reflection coating layer is a high-reflection sheet-shaped silver or nanometer reflection coating, and roll-to-roll silk-screen printing ink is arranged on the lower surface of the reflection layer. According to the scheme, the use effect of the explosion-proof membrane is effectively improved, the service life of the explosion-proof membrane is effectively prolonged, meanwhile, the production process of the explosion-proof membrane is simplified, an electroplated metal layer is prevented from being adopted, environmental protection is improved, meanwhile, the production quality of the explosion-proof membrane is effectively guaranteed, and the reflection effect on different colors and the blocking effect on infrared rays and ultraviolet rays are improved and stripping of an adhesive layer is avoided.

Description

technical field [0001] The invention relates to the production technology of an explosion-proof membrane, in particular to a 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 at the same time...
