Fireproof flame-retardant sound-absorbing cotton and preparation method thereof

Abstract

The invention discloses fireproof flame-retardant sound-absorbing cotton, prepared from the following materials in parts by weight: 40 to 60 parts of polyester fiber, 15 to 25 parts of glass fiber, 10 to 20 parts of polysulfonamide fiber, 10 to 15 parts of ES fiber, 2 to 4 parts of tetrakis hydroxymethyl phosphonium sulfate, 1 to 2 parts of a silane coupling agent KH-550, 3 to 5 parts of zinc borate, 0.5 to 1 part of decabrominated dipheny ethane, 3 to 5 parts of simethicone, 0.1 to 0.2 parts of Turkey red oil and 10 to 15 parts of composite resin. The sound-absorbing cotton has better all-frequency sound-absorbing capacity, obviously improved acoustic performance and good fireproof flame retardance and high temperature resistance, and is good in usability, high in safety factor, wide in application scope and high in practicability.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing technology, in particular to a fireproof and flame-retardant 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 sui...

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.

Moreover, ordinary sound-absorbing cotton has poor flame retardancy and low fire rating, which is easy to cause safety hazards and limits its scope of use.
