Problems solved by technology

Ordinary polyester fiber sound-absorbing cotton has a narrow sound-absorbing bandwidth, and only has a good absorption of medium and high-frequency sounds, and has limited absorption effect on low-frequency sounds.
Moreover, ordinary sound-absorbing cotton generally has a large unit weight, and is soft and less comfortable.

Abstract

The invention discloses a light antibacterial sound absorbing cotton, prepared from the following raw materials in parts by weight: 40-60 parts of dacron fiber, 10-15 parts of chitosan fiber, 10-15 parts of banana fiber, 10-15 parts of ES fiber, 0.3-0.5 part of didecyl dimethyl ammonium chloride, 2-4 parts of shell powder, 1-2 parts of silane coupling agent KH-550, 0.1-0.2 part of borneol, 2-4 parts of olive oil, and 10-15 parts composite resin. The sound absorbing cotton has better full frequency sound absorbing capability, obviously improved acoustic performance, has characteristics of light weight, ventilation softness, high comfort level and good antibacterial performance, and is good in use performance, wide in suitable range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound absorption, in particular to a lightweight antibacterial sound-absorbing cotton and a preparation method thereof. Background technique [0002] In today's society, noise pollution has become one of the major environmental pollution problems that have attracted worldwide attention after water pollution and air pollution. The use of sound-absorbing and sound-insulating materials for sound insulation and noise reduction is a common means of controlling noise pollution. At present, the commonly used sound-absorbing cotton on the market includes glass fiber sound-absorbing cotton, sponge, polyester fiber sound-absorbing cotton, etc. Glass fiber cotton is easy to cause skin itching and respiratory allergies, which is harmful to the human body and is not suitable for indoor use. Most of the sponge is a closed-cell foam material, which has limited sound absorption performance and is more suitable for ther...
