Embodiment Construction

[0015] The activated carbon sound-absorbing cotton is composed of a top layer, a back layer, and a fiber cotton layer sandwiched between the top layer and the back layer. The top layer and the back layer are made of non-woven fabric materials, and its characteristics The non-woven fabric is made of the following raw materials in parts by weight by the melt-blown method: isotactic polypropylene 100, ferric oxide 5, MnO2 3, E-12 epoxy resin 10, epoxy butyl oleate 15, Antioxidant 1010 2. Activated carbon powder 8. Peach gum 3. Straw 14. Gastrodia elata 4. Kochia chinensis 3. Prunella vulgaris 1. Additive 5.

[0016] The auxiliary agent is made of the following raw materials in parts by weight (kg): nano-carbon 1, kaolin 8, lapis lazuli 1, anti-aging agent TPPD 1, tetraisopropyl bis(dioctylphosphite acyloxy) titanate 2. Ethylene glycol 2, jade 1, ethylene bisstearamide 2, diethylene glycol dibenzoate 32, propyl gallate 2, barley oil 1, vanadium diboride 2, epicatechin Element 2; ...

Abstract

The invention discloses active carbon noise-absorbing cotton which is composed of a top surface layer, a back surface layer and a cellocotton layer clamped between the top surface layer and the back surface layer, wherein the top surface layer and the back surface layer are made of a non-woven fabric material. The anti-aging active carbon noise-absorbing cotton is characterized in that the non-woven fabric is prepared from the following raw materials in parts by weight through a melt-blowing method: 100 parts of isotactic polypropylene, 4-5 parts of ferroferric oxide, 2-3 parts of MnO2, 10-12 parts of E-12 epoxide resin, 12-15 parts of epoxy butyl oleate, 1-2 parts of antioxidant 1010, 6-9 parts of active carbon powder, 2-3 parts of peach gum, 12-14 parts of straw, 4-5 parts of rhizoma gastrodiae, 2-3 parts of broom cypress fruit, 1-2 parts of selfheal spike and 4-5 parts of accessory ingredient. The preparation method is simple and cost-saving; the prepared product is large in void volume, better in weather resistance and air permeability and good in oxygen permeability; the noise-absorbing effect of common noise-absorbing cotton is improved.

Description

[0001] technical field [0002] The invention relates to nonwoven fabric technology, in particular to an activated carbon 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 ...
