Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
Example 1
This embodiment will be described in detail with reference to fig. 1. The flame-retardant protective composite non-woven fabric comprises a spun-laced non-woven base layer 1, wherein one side of the spun-laced non-woven base layer 1 is compounded with a glass fiber layer 2 through a flame-retardant adhesive; the other side of the spunlaced nonwoven substrate 1 is compounded with the spunlaced nonwoven surface layer 3 by a flame-retardant adhesive.
The fibers used by the spunlaced nonwoven base layer 1 and the spunlaced nonwoven surface layer 3 are flame-retardant polyester fibers; visible light catalyst particles are attached to the surface of the flame-retardant polyester fiber used for the spunlaced nonwoven surface layer 3. The use of the flame-retardant polyester fiber and the glass fiber can provide good flame-retardant effect for the composite non-woven fabric. The visible light catalyst particles used are in particular TiO 2 /Fe 2 O 3 And (5) compounding powder. The visible light catalyst powder can absorb visible light in sunlight or lamplight to catalyze and decompose formaldehyde in a room into carbon dioxide and water, so that the purpose of removing formaldehyde is achieved.

Sound absorption mechanism and spectral characteristics of microporous sound absorbing materials: the sound absorption mechanism of the porous sound absorbing material is to cause air vibration in the pores when sound waves are incident on the porous material. Converting a portion of the acoustic energy into thermal energy due to friction and viscous drag of the air; in addition, heat conduction between the air in the pores and the pore walls and fibers also causes heat loss, so that the sound energy is attenuated to reduce the noise decibel value. In particular, the pore diameter of the expanded polytetrafluoroethylene film or the expanded polytetrafluoroethylene modified film is 0.01-30 mu m, the air friction and the viscous resistance of air in the aperture are further increased, and the sound wave energy is oscillated and subtracted by a plurality of layers of micropores, so that the sound wave energy is more converted into heat energy, the noise in 100 Hz-10000 Hz is obviously reduced, and the material has high sound absorption coefficient, thereby showing excellent sound absorption and noise reduction capability.
