Abstract

The invention discloses an antistatic sound-absorbing cotton. The antistatic sound-absorbing cotton comprises a top layer, a back layer and a cellucotton layer sandwiched between the top layer and the back layer, wherein the top layer and the back layer are made of a non-woven fabric material. The antistatic sound-absorbing cotton is characterized in that the non-woven fabric is prepared from the following raw materials by weight through melt-blowing: 100 parts of isotatic polypropylene, 7 to 9 parts of fatty alcohol-polyoxyethylene ether, 2 to 3 parts of alkyl ethyl ether polysiloxane polysilicone, 2 to 3 parts of aluminum phosphate, 1 to 2 parts of tin oxide, 13 to 16 parts of glycerol triacetate, 1 to 2 parts of magnesium silicate, 1 to 2 parts of nanometer silica, 2 to 3 parts of calcium alginate, 1 to 2 parts of sodium silicate, 20 to 24 parts of twigs, 1 to 2 parts of mint leaves, 2 to 3 parts of licorice, 3 to 4 parts of gynostemma pentaphylla and 4 to 5 parts of an auxiliary agent. According to the invention, a melt-blowing process is used for preparation of the non-woven fabric and has the advantages of easiness, good controllability and high production efficiency; and the prepared sound-absorbing cotton provided by the invention has the advantages of an antistatic property, soft hand feel, smoothness, good surface flatness, strong adsorptivity, a good sound-absorbing effect, etc.

Description

[0001] technical field [0002] The invention relates to nonwoven fabric technology, in particular to an antistatic sound-absorbing cotton and a preparation method thereof. Background technique [0003] 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. To stay away from noise, all we can do is sound absorption and sound insulation. Sound-absorbing cotton can convert the vibration energy of medium and high-frequency noise generated in life into the kinetic energy of the fine denier fibers inside the sound-absorbing cotton and conduct it into heat energy and disappear, achieving the function of sound absorption and noise reduction. [0004] Sound-absorbing cotton can be laminated with multiple layers of non-woven fabrics, or combined with other materials to make sound-absorbing and sound-insulating materials. Non-woven fabrics are oriented or ran...
