Abstract

The invention discloses PET (polyethylene terephthalate) fiber / polybenzimidazole fiber composite sound absorption cotton, which comprises the following raw materials in parts by weight: 70-80 parts of PET fiber, 40-50 parts of polybenzimidazole fiber, 10-15 parts of emulsifiers OP-40, 5-10 parts of peregal O-25, 80-100 parts of PP (propene polymer), 30-40 parts of ABS (acrylonitrile butadiene styrene), 15-20 parts of titanium dioxide, 10-15 parts of modified diatomite, 2-3 parts of stearic acid, 5-8 parts of di-iso-octyl sebacate, 4-6 parts of antimonous oxide, 2-3 parts of glyceryl monostearate, 1-2 parts of phenyl triethoxysilane, 2-3 parts of zinc stearate, 1-2 parts of dibasic lead phosphite, 0.5-1.5 parts of anti-aging agents MB, and 1-2 parts of antioxidant 168. The sound absorption cotton prepared by the method has the advantages of excellent appearance evenness, even thickness, soft hand feel, excellent product bonding degree, strong tensile property, excellent sound absorption performance, excellent flame retardant efficiency and the like.

Description

technical field [0001] The invention relates to nonwoven fabric technology, in particular to a PET fiber / polybenzimidazole fiber composite sound-absorbing cotton and a preparation method thereof. Background technique [0002] Noise is one of the three major public hazards that pollute the environment in modern society. Noise directly affects people's health. With the progress of society, people put forward higher and higher requirements for the prevention and control of noise that pollutes the environment. Sound-absorbing cotton can convert the vibration energy of medium and high-frequency noise generated in life into the kinetic energy of the fine denier fibers inside the sound-absorbing cotton, and convert it into heat energy and disappear, achieving the function of sound absorption and noise reduction. Therefore, sound-absorbing cotton has good sound-absorbing, heat-insulating and warm-keeping properties, and has been widely used in the fields of building materials, autom...
