Car exterior black film with high weather resistance function

Abstract

The invention relates to the technical field of car films, in particular to a car exterior black film with a high weather resistance function. The car exterior black film comprises a car film body, wherein an adhesive layer can ensure that the car film body is attached to window glass; a heat insulation layer can effectively insulate heat and increase stability of the car film body; a light insulation layer can effectively reduce irradiation of strong light; a dyeing layer has the characteristics of facilitating coloring and being high in heat resistance and cheap; attractiveness of the car film can be increased through coloring, and the manufacturing cost is reduced; a protective layer can effectively prevent scratches on the surface of the film, and plays a certain sound insulation role;bubbles generated during film pasting can be removed by air holes; by means of a vibration sensor, a single chip microcomputer and a buzzer, the buzzer emits sound to remind people nearby when no onesees an accident, so that the injured can be rescued in time. The car exterior black film has simple structure, greatly improves safety of users, and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of car film, in particular to a car exterior black film with high weather resistance function. Background technique [0002] Car film, referred to as "car film", is a film that is attached to the car glass for beauty, safety and heat insulation. Its basic properties include safety, clarity, anti-glare, UV protection, heat insulation, anti-scratch, sufficient shelf life and privacy protection, etc. However, ordinary PVC film has a certain milky white translucency, which will make the car The paint surface becomes dark, and it is prone to problems such as blistering and falling off of the protective film. Moreover, the safety factor of ordinary PVC film is not high enough when it is used, which is a safety hazard. Moreover, when the existing car film is broken, it will When the impact force is too large, it is easy to tear the film of the car directly, causing the glass to scatter, and when there are few peop...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a car exterior black film with a high weather resistance function, to solve the problem that when the impact force proposed in the above background technology is too large, it is easy to tear the car film, so that the glass is scattered. When no one is found at the scene, it cannot effectively notify the nearby people to come to rescue and other problems
