Light flexible noise reduction non-woven composite material, preparation method and application

The invention belongs to the fields of agriculture, light industry and textile, and particularly discloses a light flexible noise reduction non-woven composite material and a production method. The material can be used as a noise reduction material in the fields of buildings, factories, home improvement and home appliances. The composite material comprises at least one sound insulation material layer and at least two sound absorbing non-woven fabric layers, wherein the sound insulation material layer and the sound absorbing non-woven fabric layers are alternately laminated and are adhered through an adhesive; and the composite material has thickness of 1.4-10 mm. Different from the conventional noise reduction material, the sound insulation material layer and the sound absorbing material layer are manufactured by using a sound absorbing and sound insulation combined principle respectively, and then at least two layers of the two material layers are adhered through the adhesive, so that the material is soft, f
