Problems solved by technology

[0002] At present, the door of middle and low-end cars only uses a single layer of PE film as the door waterproofing film. The door waterproofing film made of a single layer of PE film has almost no sound insulation, sound absorption, noise reduction and heat preservation effect, and the door made of a single layer of PE film is waterproof. The energy consumption of new energy vehicles with sheet film is too high, so that in summer or winter, high-power air conditioners are needed to make people comfortable. Shorter driving range per charge
The car door waterproof sheet film made of single-layer PE film is noisy, and the noise is easy to make people tired, affecting driving safety and consumers' physical and mental health
