It is clear and transparent, and is processed through multiple processes such as metallization coating, magnetron sputtering, and interlayer synthesis to become a film with different properties that can stick tightly to glass fragments.
[0003] In the hot summer, the thermal insulation film can effectively block the heat from direct sunlight, making the temperature inside the car several degrees lower than when the film is not applied. It can also filter out heat-carrying infrared rays, significantly lowering the temperature inside the car and improving comfort, thereby reducing the power consumption of the car's air conditioner and achieving energy-saving and environmental protection effects.
[0004] However, when the automotive thermal insulation film in the prior art is used, the thermal insulation layer arranged therein has a relatively limited effect in isolating the heat in the sunlight, and cannot effectively isolate the heat in the sunlight, and has a relatively limited effect on reducing the temperature inside the car.
