Antibacterial sound-absorbing cotton and preparation method thereof

Abstract

Disclosed antibacterial sound-absorbing cotton consists of a top layer, a bottom layer, and a fiber cotton layer disposed between the top layer and the bottom layer. The top layer and the bottom layer are made from a non-woven fabric material, and the antibacterial sound-absorbing cotton is characterized in that the non-woven fabric material is prepared from the following raw materials in parts by weight by employing a melt blowing method: 100 parts of isotactic polypropylene, 12-15 parts of methyl methacrylate, 1-2 parts of 2-methylsuccinic acid, 1-2 parts of chlorothalonil, 2-3 parts of calcium stearate, 12-15 parts of diisobutyl phthalate, 4-6 parts of paraffin oil, 1-2 parts of zinc oxide, 10-12 parts of eggplant straw, 4-5 parts of active carbon, 2-3 parts of spatholobus stem, 1-2 parts of Chinese prickly ash, 1-2 parts of achyranthes aspera L., 2-3 parts of common clubmoss herb and 4-5 parts of an auxiliary agent. The prepared sound-absorbing cotton has antibacterial property, and is capable of satisfying the usage requirement of special industries, and the product provided by the invention has the advantages of large porosity, strong adsorptivity and the like.

Description

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

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.
