Abstract

The invention relates to the technical field of spinning materials and discloses a polytetrafluoroethylene interlayer super-hydrophobic sound-absorption non-woven spinning composite material and a preparation method thereof. The spinning composite material comprises bottom-layer non-woven cloth, a polytetrafluoroethylene membrane and top-layer non-woven cloth, wherein the polytetrafluoroethylene membrane is sandwiched between the non-woven cloth and the top-layer non-woven cloth; the lower surface of the top-layer non-woven cloth is adhered to the upper surface of the polytetrafluoroethylene membrane through an adhesive; the upper surface of the bottom-layer non-woven cloth is adhered to the lower surface of the polytetrafluoroethylene membrane; the spinning composite material is preparedthrough steps of gluing, adhesion and curing in sequence. The spinning composite material provided by the invention has a good sound absorption effect.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a polytetrafluoroethylene interlayer super-hydrophobic sound-absorbing needle-punched non-woven textile composite material and a preparation method thereof. Background technique [0002] With the continuous development of modern industry, the problem of noise pollution has become increasingly serious, and now it is called the four major environmental problems on the earth together with water pollution, air pollution and solid waste pollution. Noise pollution is extremely harmful to the human body. It not only makes people feel difficult to concentrate and irritable, but also may cause cardiovascular diseases and induce other diseases, thereby shortening people's life span. Because of this, the harm caused by noise pollution has been regarded as the second killer of human public health after air pollution, how to reduce noise pollution has become an important task nowadays. So fa...
