[0001] The utility model relates to the technical field of automobile sound insulation, in particular to a self-adhesive sound insulation foam. Background Art

[0002] As we all know, the noise generated by a car when idling, accelerating or driving on different road conditions is amplified after resonance or resonance between the chassis and the body, and is transmitted into the car, making the driver and passengers feel uncomfortable. As cars gradually enter families, car owners pay more and more attention to driving quality, and they also care more and more about the noise during driving. In fact, the noise in the car is enough to affect the conversations of the passengers, the listening of music, and even the mood of the driver.

[0003] For the sound insulation cotton inside the car door, rainwater will seep into the inside of the car door during rain. Although the rainwater will be discharged through the drainage holes of the car door, the rainwater will still seep into the inside of the sound insulation cotton. Over time, the sound insulation cotton will become moldy, thereby affecting the sound insulation effect of the sound insulation cotton. For this reason, a self-adhesive sound insulation foam is proposed. Utility Model Content
