Abstract

The invention discloses seaweed carbon fiber composite sound absorption cotton which is prepared from the following raw materials in parts by weight: 40 to 60 parts of polyester fibers, 15 to 25 parts of seaweed carbon fibers, 5 to 10 parts of soybean fibers, 10 to 15 parts of ES fibers, 0.3 to 0.5 part of petroleum sodium sulfonate, 0.1 to 0.2 part of microcrystalline wax, 0.1 to 0.2 part of dioctyl sebacate, 2 to 4 part of castor oil, 1 to 2 parts of silane coupling agent KH-550, 2 to 4 parts of illite powder and 10 to 15 parts of composite resin. The sound absorption cotton provided by the invention has better whole frequency sound absorption ability, so the acoustic performance is obviously improved, the sound absorption cotton also has the far infrared ray radiation function, so a better health effect on a human body is realized, the usability is good, the range of application is wide and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of sound absorption, in particular to a seaweed carbon fiber composite 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...
