Referring to fig. 1-4, a vehicle navigation rupture membrane is shown, which is composed of a layered structure and comprises a PET safety base layer 2, wherein the inner side surface of the PET safety base layer 2 is connected with a PET release film 1 through an adhesive layer, and the outer side surface of the PET safety base layer 2 is sequentially provided with a nano ceramic heat-insulating layer 4, a blue light cut-off sheet layer 6 and a scratch-resistant layer 7; the scratch-resistant layer 7 is a high-transmittance anti-fingerprint AF film, and the blue light cut-off sheet layer 6 is a thin film interference type cut-off filter capable of cutting off the wavelength of 400nm-480 nm.
Specifically, the PET safety base layer 2 is composed of a high-strength and high-transparency PET polyester film, so that very strong impact resistance is provided for vehicle navigation, and the condition that a vehicle navigation screen is smashed due to the fact that children play in a vehicle is prevented; the nano ceramic thermal insulation layer 4 can effectively insulate heat for vehicle navigation, prevent the vehicle navigation from being influenced by too high temperature or too low temperature in the vehicle, and reduce the water fog on a vehicle navigation screen to a certain extent; in addition, the nano ceramic thermal insulation layer 4 is made of a nano ceramic material, the nano ceramic material is a titanium nitride ceramic material, the chemical property is stable, the nano ceramic material is not easy to oxidize, the service life is long, and no interference is caused on radio signals, particularly short wave signals (GPS) of satellites, and the shielding effect of a metal film is avoided. In order to avoid the influence on eyes caused by frequent watching of vehicle navigation by a driver, the blue light cut-off sheet layer 6 arranged on the explosion-proof membrane can filter the wavelength of 400nm-480nm, so that the increase of the toxin amount in a yellow spot area in the eyes caused by the blue light in the wavelength is prevented, and the vision of the driver is reduced; meanwhile, the situation that due to the fact that the wavelength of blue light is short, the gathering point falls at a position which is closer to the front point of the retina, and therefore double vision and concentration of attention of a driver are prone to happening is avoided; the life safety of the driver in the conditions of long-time driving on the expressway and the like is effectively guaranteed. In addition, the anti-explosion film is provided with a high-transmittance anti-fingerprint AF film, so that fingerprints can be effectively prevented, oil and dust can be effectively prevented, the anti-explosion film also has very high light transmittance, marks can be prevented from being left on a vehicle-mounted navigation screen by grease, and images can be prevented from being shielded; and the high-transparency anti-fingerprint AF film has a very good anti-scratch and wear-resistant effect, and prevents a screen of the vehicle navigation from being scratched to shield images.
It should be noted that when the explosion-proof membrane needs to be attached to the vehicle-mounted navigation, the PET release film 1 is torn off, and then the surface where the adhesive layer is mounted can be attached to the vehicle-mounted navigation.

Wherein, the heating resistor layer 3 is a silk screen heating resistor layer 3 or a transparent heating resistor layer 3. The heating resistance layer 3 can disperse water mist on the explosion-proof membrane, so that the explosion-proof membrane and the vehicle-mounted navigation device do not have mist, and a driver and passengers can see images on the vehicle-mounted navigation device clearly.
According to the scheme, the mounting adhesive layer can be made of the acrylate adhesive, the acrylate adhesive has the advantages of high strength, impact resistance, good weather resistance and strong impact resistance and shearing force, and the anti-explosion film can be stably adhered to the vehicle-mounted navigation device even in regions with changeable climates.
In some specific embodiments, in order to avoid dazzling and difficulty in seeing images on the car navigation due to sunlight reflected by the car navigation, a silicon dioxide film 5 is arranged between the nano ceramic thermal insulation layer 4 and the blue light cut-off sheet layer 6. The silicon dioxide film 5 is of a nano structure, a large number of mesopores exist in the silicon dioxide film, and the mesopores can effectively resist dizziness.
In some embodiments, when the existing explosion-proof film is peeled off from the PET release film 1, it is difficult to peel off the existing explosion-proof film, which takes a lot of time, and referring to fig. 2, 3 and 4, the PET release film 1 includes a first release film 11 for covering the first transparent PET security substrate 2 and a second release film 12 disposed on an edge of the first release film 11; a linear opening 111 is arranged on the first release film 11, one part of the second release film 12 is positioned on the outer side of the first release film 11, and the other part of the second release film passes through the linear opening 111 and is positioned on the inner side of the first release film 11; the second that is located the first type membrane 11 outside from type membrane 12 with first from type membrane 11 bonding, be located first from type membrane 11 inboard second from type membrane 12 with first from type membrane 11 non-fixed ground laminating mutually. In this way, when the PET release film 1 is peeled, a finger can be inserted from the linear opening 111, thereby peeling the PET release film 1; since the second release film 12 located inside the first release film 11 is non-fixedly attached to the first release film 11, fingers can be easily inserted; and before the fingers are inserted into the linear opening 111, the second release film 12 positioned at the inner side of the first release film 11 can prevent dust from being adhered to the mounting adhesive layer. Preferably, the second release film 12 is disposed at a corner of the first release film 11, so that the PET release film 1 can be easily uncovered from the corner.
The scheme is specific, and the second release film 12 positioned on the outer side of the first release film 11 is fixedly bonded with the first release film 11 through an OCA (optically clear adhesive). The OCA adhesive has the advantages of high adhesion, high weatherability, water resistance, high temperature resistance, ultraviolet resistance, controlled thickness, uniform spacing, and no yellowing (yellowing), peeling and deterioration over a long period of time.
