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, the surface and interior of the sound-absorbing cotton are easy to accumulate dust and breed various bacteria and mites, which is not conducive to human health and environmental cleanliness.

Abstract

The invention discloses dustproof anti-mite sound absorption cotton. The dustproof anti-mite sound absorption cotton is prepared from, by weight, 40-60 parts of polyester fibers, 5-10 parts of aloe fibers, 20-30 parts of hemp fibers, 10-15 parts of ES fibers, 0.5-1 part of cocamidopropyl betaine, 1-2 parts of silane coupling agent KH-550, 0.5-1 part of glycerol monolaurate, 1-2 parts of teflon micro powder, 0.05-0.1 part of decamethrin, 3-5 parts of white mineral oil, 1-2 parts of propylene glycol and 10-15 parts of compound resin. The sound absorption cotton has better full-frequency sound absorption capacity, the acoustic performance is obviously improved, and the sound absorption cotton has the functions of preventing dust and mites and resisting bacteria, is easy to clean, safe, environmentally friendly, wide in application range and high in practicability and has good using performance and hygiene performance.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing technology, in particular to a dust-proof and mite-proof 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 suitabl...
