[0002] A car film is a thin film attached to the front and rear windshields, side windows and sunroof of a vehicle. Its main function is to block ultraviolet rays, block some heat, prevent injuries caused by glass splashing, and prevent glare. At the same time, based on the one-way perspective performance of the solar film, it can achieve the purpose of protecting personal privacy. The car film is achieved by coating a layer of dark reflective material on the surface of the film to reflect visible light and infrared rays, thereby achieving a heat insulation effect.

[0003] However, in the existing technology, the darker the color of the car insulation film, the better the insulation effect, but the light transmittance will be correspondingly reduced, which makes it inconvenient to use it on the front windshield. Some heat-absorbing films insulate by absorbing heat, but when in use, the temperature of the film itself will be relatively high, which will cause secondary radiation and also affect the service life of the film itself. Utility Model Content

[0010] Preferably, a release film is attached to the bottom surface of the glue layer, and a pulling gasket is fixed to an edge of one side of the release film extending to the outside of the glue layer.

[0011] Preferably, the distance between the outer side of the negative pressure groove and the edge of the glue layer is 5-10 cm.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1-3 As shown, the utility model provides a heat-insulating automobile film, comprising an anti-wear outer layer 1, an outer heat-insulating metal layer 2 is fixed to the bottom surface of the anti-wear outer layer 1, an anti-ultraviolet layer 3 is fixed to the side of the outer heat-insulating metal layer 2 away from the anti-wear outer layer 1, a UV absorbing layer 4 is fixed to the side of the anti-ultraviolet layer 3 away from the outer heat-insulating metal layer 2, an inner heat-insulating metal layer 5 is fixed to the side of the UV absorbing layer 4 away from the anti-ultraviolet layer 3, a polyvinyl chloride bottom layer 6 is fixed to the side of the inner heat-insulating metal layer 5 away from the UV absorbing layer 4, and a glue layer 7 is fixed to the side of the polyvinyl chloride bottom layer 6 away from the inner heat-insulating metal layer 5.

[0022] The following is a detailed description of the specific settings and functions of this embodiment: the thickness of the anti-wear outer layer 1 is greater than the thickness of the outer thermal insulation metal layer 2. The protective characteristics of the anti-wear outer layer 1 can better protect the outer thermal insulation metal layer 2, thereby ensuring the thermal insulation integrity of the outer thermal insulation metal layer 2 during use. The thickness of the outer thermal insulation metal layer 2 is greater than the thickness of the ultraviolet protection layer 3, the thickness of the UV absorption layer 4 is equal to the thickness of the anti-wear outer layer 1, the thickness of the inner thermal insulation metal layer 5 is less than the thickness of the UV absorption layer 4, the thickness of the polyvinyl chloride bottom layer 6 is equal to the thickness of the inner thermal insulation metal layer 5, and the thickness of the glue layer 7 is less than the thickness of the polyvinyl chloride bottom layer 6. Through the support and tensile properties of the polyvinyl chloride bottom layer 6, combined with the glue layer 7, the automobile film can better support the glass after being bonded and fixed to the glass during bonding, thereby preventing the glass from shattering when it breaks, thereby reducing the safety of the glass after it is broken.

[0023] like Figure 1-3 As shown, a negative pressure groove 10 is provided on the inner edge of the bottom of the glue layer 7, and the negative pressure groove 10 is set as a hollow rectangle that cooperates with the anti-wear outer layer 1. The distance between the outside of the negative pressure groove 10 and the edge of the glue layer 7 is 5-10 cm. A release film 8 is adhered to the bottom surface of the glue layer 7, and the release film 8 extends to one side edge of the outside of the glue layer 7 and is fixed with a pulling gasket 9. The release films 8 inside and outside the negative pressure groove 10 are split designs. The release film 8 inside the negative pressure groove 10 extends to the outer edge of the negative pressure groove 10 and is aligned with the release film 8 outside the negative pressure groove 10. When paving, you can first pull the release film 8 inside the negative pressure groove 10, stick and press the negative pressure groove 10 to form a negative pressure fit, and then tear off the release film 8 on the outside and bond it to fix.

[0024] The method of use and working principle of this device: When in use, pinch the pulling gasket 9 to pull the release film 8 to separate the release film 8 from the glue layer 7, and stick it while pulling. The wear-resistant outer layer 1 increases the wear-resistant performance of the car film to resist the damage caused by friction after external objects fall on the car film. The double insulation design of the internal outer insulation metal layer 2 and the inner insulation metal layer 5 can ensure the heat insulation effect while ensuring light transmission and filtering. The anti-ultraviolet layer 3 and the UV absorption layer 4 cooperate to not only increase the heat It can absorb and block ultraviolet rays, thereby temporarily slowing down the aging speed of plastic accessories in the car. When pasting, first stick the glue layer 7 on the inner side of the negative pressure groove 10 to the car body glass, and then press the negative pressure groove 10 to form a negative pressure at the bottom of the negative pressure groove 10, and stick it to the glass surface. Then press the anti-wear outer layer 1 on the outside of the negative pressure groove 10, so that the anti-wear outer layer 1 on the outside of the negative pressure groove 10 is stuck to the glass surface through the glue layer 7, so as to reinforce the car film without affecting the aesthetics during installation.
