Active carbon noise-absorbing cotton and preparation method thereof

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 ...

AI Technical Summary

Problems solved by technology

However, there are many deficiencies in the existing sound-absorbing cotton products and their manufacturing methods, mainly as follows: the production process is not environmentally friendly; Flame retardant treatment; insufficient adhesion, easy to disperse, poor tensile strength; insufficient appearance and flatness, large deviation in thickness, etc.
