Abstract

The invention discloses a flame-retardant, antibacterial, heat-insulating and sound-insulating multifunctional material used in the field of automobiles, wherein the material comprises a surface layer, a middle layer and a bottom layer, and the middle layer sequentially comprises a flame-retardant layer, a melt-blown layer, a sound-insulating layer and an antibacterial layer. According to the invention, the flame-retardant, antibacterial, heat-insulating and sound-insulating multifunctional material simultaneously has multiple functions of flame retardance, bacteria resistance, heat insulationand sound insulation, further has reduced cost and reduced technical difficulty, can be used in the field of automobiles so as to achieve comfortable and safe automobile riding environment, and can be used in other occasions.

Description

technical field [0001] The invention relates to the technical field of automobile decoration materials, in particular to a flame-retardant, antibacterial, heat-insulating and sound-insulating multifunctional material used in the automobile field. Background technique [0002] Sound is produced by the vibration of the surface of the object, which causes the air molecules to move back and forth, which causes the local compression and expansion of the air density and spreads. Like waves on the surface of water. Sound is a wave and a kind of energy, which is transmitted through the medium by the vibration of objects. Noise is a kind of sound, and its penetrating power is very strong. [0003] At present, the basic methods of sound insulation materials are absorption and shielding. Absorption: The attenuation of the energy of passing sound due to "friction" within a porous material. Example: sponge, plush, fiberglass. Shielding: Reduces the transmission of sound energy by re...
