A kind of explosion-proof film and its manufacturing method and a kind of traffic recorder

Abstract

The invention relates to an explosion-proof membrane, a method for making the explosion-proof membrane and a driving recorder. The explosion-proof membrane includes an anti-scratch layer, a main film PET base material, a metal oxide film layer and an installation adhesive layer, an anti-scratch layer, a main The film PET base material, the metal oxide film layer, and the installation adhesive layer are arranged sequentially from top to bottom. The metal oxide film is a non-conductive film. The production method of the explosion-proof film includes using non-conductive vacuum evaporation on the back of the main film PET The coating method or coating method is used to make a non-conductive metal oxide film layer and coat an installation adhesive layer on the other side of the metal oxide film layer relative to the main film PET base material layer and coat one on the front side of the main film PET base material layer. Anti-scratch layer. This explosion-proof film can meet various needs in the actual use process, and solve related problems such as the conduction of the explosion-proof film body, the inability to expand the rearview mirror function on the driving recorder, and complicated processing technology.

Description

【Technical field】 [0001] The invention relates to an explosion-proof membrane, in particular to an explosion-proof membrane coated with a non-conductive metal oxide film layer, a manufacturing method thereof and a driving recorder. 【Background technique】 [0002] The explosion-proof film is widely used because it can prevent the glass from splashing when the glass cover is broken, especially in the automotive field. The mirror explosion-proof film used on the car driving recorder is a typical example. , There are many types of explosion-proof membranes for driving recorders on the market, with different functions. Some explosion-proof membranes have a single color, which cannot match the color of other parts of the car, and cannot meet the needs of the public. Some explosion-proof membranes are based on processing links. The film body is conductive, which will cause signal interference when used in a driving recorder. Some explosion-proof films have weak reflection and light...

[0002] The explosion-proof film is widely used because it can prevent the glass from splashing when the glass cover is broken, especially in the automotive field. The mirror explosion-proof film used on the car driving recorder is a typical example. , There are many types of explosion-proof membranes for driving recorders on the market, with different functions. Some explosion-proof membranes have a single color, which cannot match the color of other parts of the car, and cannot meet the needs of the public. Some explosion-proof membranes are based on processing links. The film body is conductive, which will cause signal interference when used in a driving recorder. Some explosion-proof films have weak reflection and light transmission performance, and cannot expand the rearview mirror function on the driving recorder, which is not conducive to product multi-functional integration and cost. savings

In the processing of explosion-proof membranes, the usual processing techniques are relatively complicated, resulting in a waste of resources. How to obtain an explosion-proof membrane that can solve the above-mentioned related problems and has a simple processing method is a problem that people have always been concerned about.
