Explosion-proof membrane and preparation method of membrane as well as automobile data recorder

Abstract

The invention relates to an explosion-proof membrane, a preparation method of a membrane as well as an automobile data recorder. The explosion-proof membrane comprises an anti-scratch layer, a main membrane PET substrate layer, a metal oxide membrane layer and a mounting glue layer which are arranged from up to bottom in sequence, wherein the metal oxide membrane layer is a non-conductive membrane. The preparation method of the explosion-proof membrane comprises the following steps: preparing the non-conduction metal oxide membrane layer on the back surface of the main membrane PET substrate layer through a non-conduction vacuum evaporation coating method; coating the other side of the main membrane PET substrate layer with the mounting glue layer and coating the front surface of the main membrane PET substrate layer with the anti-scratching layer. According to the explosion-proof membrane, multiple requirements during actual usage can be met and the problems that the explosion-proof membrane is conductive, the rear view mirror function cannot be extended on the automobile data recorder and the processing technique is complicated are solved.

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...

Problems solved by technology

[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.
