Abstract
The invention relates to interior sound-absorbing cotton. The interior sound-absorbing cotton comprises a flame-retardant mesh layer covering the surface, and a sound-absorbing cotton sealing edge isarranged at the boundary of the sound-absorbing cotton. The flame-retardant mesh layer on the surface layer comprises 25-35% of basalt fibers, 15-25% of glass fibers, 10-15% of carbon fibers, 5-15% ofmeta-aramid fibers, 5-15% of flame-retardant nylon fibers, 5-10% of flame-retardant polyamide fibers, 5-8% of phenolic fibers, 5-15% of alloy fibers and 5-7% of polysulfonamide fibers. The flame-retardant mesh layer is formed by weaving a fiber material. The alloyfiber comprises the following raw materials in percentage by weight: 25-45% of aluminum, 15-20% of titanium, 10-15% of iron, 5-10% oftungsten, 5-10% of chromium and 5-15% of copper. According to the interior sound-absorbing cotton, the outer layer of the sound-absorbing cotton is wrapped with the flame-retardant mesh layer, so thesound-absorbing effect of the sound-absorbing cotton is not damaged while flame retardance is conducted on the sound-absorbing cotton, the sound-absorbing effect of the sound-absorbing cotton is improved, and the toughness and the rigidity of the sound-absorbing cotton are improved.
Description
technical field [0001] The invention relates to the technical field of sound-absorbing cotton materials, in particular to an interior sound-absorbing cotton. Background technique [0002] In today's society, noisepollution 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 noisepollution. At present, the commonly used sound-absorbing cotton on the market includes glass fiber sound-absorbing cotton, sponge, polyesterfiber sound-absorbing cotton, etc. Glass fiber cotton is easy to cause skinitching 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 thermal insulation. Ordinary polyest...
