Disclosure of Invention

The utility model aims to provide high-molecular PET sound-absorbing cotton.

The novel sound absorbing cotton has the innovation points that the anti-collision layer and the anti-collision adhesive tape are adopted, so that the anti-collision performance of the sound absorbing cotton can be improved, the anti-collision layer has good toughness, can rebound after being impacted, is not easy to crease, and has high durability; the sponge has the functions of sound absorption and buffering, and further protects sound absorption cotton.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a macromolecular PET inhales sound cotton, includes the body, one side of body is provided with the anticollision layer, one side uniform spacing that the body was kept away from to the anticollision layer has a plurality of crashproof strips, and each crashproof strip is arranged along the length direction of anticollision layer, the cladding has one deck sponge on anticollision layer and the crashproof strip. The anti-collision layer and the anti-collision adhesive tape are adopted, so that the anti-collision performance of the sound-absorbing cotton can be improved, the anti-collision layer is good in toughness, can rebound after being impacted, is not easy to crease, and is high in durability; the sponge has the functions of sound absorption and buffering, and further protects sound absorption cotton.

Preferably, one side of the anti-collision strip away from the anti-collision layer is arc-shaped. The arc-shaped surface is the most stable, has high bearing capacity, and effectively reduces the impact force of the outside on the anti-collision strip.

Preferably, the anti-collision layer is a palm pad. The palm cushion has lasting elasticity, is not easy to deform and is not easy to generate noise.

Preferably, an upper non-woven fabric layer and a lower non-woven fabric layer are arranged between the palm cushion and the body, the peripheries of the upper non-woven fabric layer and the lower non-woven fabric layer are bonded through glue, and activated carbon powder is filled between the upper non-woven fabric layer and the lower non-woven fabric layer. The activated carbon powder has the function of absorbing peculiar smell, the non-woven fabric layer can wrap the most activated carbon powder, the activated carbon powder is prevented from leaking, the non-woven fabric is high in air permeability, and the activated carbon powder is convenient to remove the peculiar smell.

Preferably, a high molecular absorbent fiber layer is arranged between the palm cushion and the upper non-woven fabric layer. The high molecular moisture-absorbing fiber layer has the functions of moisture prevention and moisture absorption, and prevents the moisture from affecting the active carbon powder, the sound-absorbing cotton and the like.

Preferably, an anti-slip adhesive tape is arranged around one side of the body away from the anti-collision layer. The anti-slip adhesive tape increases the friction force of the sound-absorbing cotton in the installation process, so that the sound-absorbing cotton is not easy to slip off from an object.

The beneficial effects of the utility model are as follows:

1. the anti-collision layer and the anti-collision adhesive tape are adopted, so that the anti-collision performance of the sound-absorbing cotton can be improved, the anti-collision layer is good in toughness, can rebound after being impacted, is not easy to crease, and is high in durability; the sponge has the functions of sound absorption and buffering, and further protects sound absorption cotton.

2. The activated carbon powder has the function of absorbing peculiar smell, the non-woven fabric layer can wrap the most activated carbon powder, the activated carbon powder is prevented from leaking, the non-woven fabric is high in air permeability, and the activated carbon powder is convenient to remove the peculiar smell.

3. The high molecular moisture-absorbing fiber layer has the functions of moisture prevention and moisture absorption, and prevents the moisture from affecting the active carbon powder, the sound-absorbing cotton and the like.
