Sound absorption cotton for heat preservation and decoration and preparation method thereof

Abstract

The invention discloses sound absorption cotton for heat preservation and decoration. The sound absorption cotton is prepared from the following raw materials in parts by weight: 40 to 60 parts of polyester fiber, 10 to 15 parts of linen fiber, 5 to 10 parts of bamboo carbon fiber, 5 to 10 parts of spandex fiber, 10 to 15 parts of ES (Ethylene-Propylene Side By Side) fiber, 2 to 4 parts of sea-foam stone powder, 1 to 2 parts of diatomaceous earth, 1 to 2 parts of silane coupling agent KH-550, 2 to 4 parts of liquid paraffin, 0.3 to 0.5 part of glycerin monostearate and 10 to 15 parts of composite resin. The sound absorption cotton disclosed by the invention has the characteristics that a whole-frequency sound absorption ability is better, the acoustic performance is obviously increased, the elasticity is good, environment protection is realized, and the texture is light and thin; the sound absorption cotton is good in heat preservation and heat insulation performance, suitable for architectural decoration, good in using performance, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound absorption, in particular to a sound-absorbing cotton for heat preservation and decoration 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 suitab...

AI Technical Summary

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.
