Abstract

The invention discloses three-component sound-absorbing cotton capable of generating negative ions and efficiently adsorbing formaldehyde and VOC. The three-component sound-absorbing cotton is a composite layer composed of heat-storage and temperature-adjusting negative-ion PP micro-nano fiber, activated carbon fiber and PET hollow fiber. The composite layer is obtained online through compoundingby means of a melt blowing-dry process fiber net. The heat-storage and temperature-adjusting negative-ion PP micro-nano fiber comprises 100 parts of PP slices and 2-10 parts of negative ion PP masterbatch. The two sides of the composite layer can be covered with surface layers which are made of PP negative ion non-woven cloth materials or aluminum foil. The surface layers and the composite layerare compounded and subjected to ginning and ultrasonic edge sealing, the product is cut into various required sizes and specifications, and the three-component sound-absorbing cotton is obtained. Thesound-absorbing cotton has better full-frequency sound-absorbing capacity, especially can better absorb medium-and-low frequency noise, and also has mildew-resistant, environmental protection, flame-retardant properties. By means of the sound-absorbing cotton, the negative ion environment can be generated, metabolism of the human body can be promoted, the health can be maintained, and the physiquecan be improved; formaldehyde, benzene and VOC can be efficiently removed, and meanwhile, removal of odor, secondhand smoke and peculiar smell is quite obvious.

Description

technical field [0001] The invention relates to the field of sound-absorbing materials, in particular to a three-component sound-absorbing cotton that generates negative ions and efficiently absorbs formaldehyde and VOC. Background technique [0002] Car noise directly affects people's physical and mental health and the improvement of quality of life. Long-term exposure to noise can cause hearing loss and even induce some diseases. Tests have shown that: 80 decibels will reduce the driver's attention by 10%; 90 decibels will reduce 20%. To stay away from noise, all we can do is sound absorption and sound insulation. The sound-absorbing cotton can convert the medium and high-frequency noise vibration energy generated by the vibration of the car body into the kinetic energy of the fine denier fibers inside the sound-absorbing cotton, and convert it into heat energy and dissipate it to achieve the function of sound absorption and noise reduction. In the field of automobile pr...
