Abstract

The invention discloses sound-absorbing cotton with a mosquito avoiding function. The sound-absorbing cotton consists of a top surface layer, a back surface layer and a fiber cotton layer clamped between the top layer and the back layer, wherein the top surface layer and the back surface layer are made of a non-woven fabric material. The sound-absorbing cotton is characterized in that the non-woven fabric material is prepared from the raw materials in parts by weight with a melt blowing method: 100 parts of isotatic polypropylene, 1-2 parts of acetofenate, 4-5 parts of polyvinyl alcohol, 1-2 parts of calcium-zinc stabilizer, 2-3 parts of antimonous oxide, 12-15 parts of acetyl triethyl citrate, 1-2 parts of polyvinyl pyrrolidone, 12-14 parts of diatomaceous earth, 1-2 parts of gypsum rubrum, 3-4 parts of amur corktree bark, 1-2 parts of willow leaves, 2-3 parts of isatis root, 1-2 parts of rhizoma paridis and 4-5 parts of aid. A mosquito repellent is uniformly distributed in the sound-absorbing cotton, so that the prepared sound-absorbing cotton has the advantages of good mosquito repelling effect, high wet resistance, high adsorptivity, remarkable sound-absorbing effect, and the like.

Description

[0001] technical field [0002] The invention relates to nonwoven fabric technology, in particular to a sound-absorbing cotton with the function of repelling mosquitoes 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-wov...
