Sound-absorbing, radiation-proof, antibacterial and deodorant decorative film for wall

Abstract

The invention relates to a decorative film. The decorative film comprises a base layer (1) and a surface layer (2) and is characterized in that micropores (3) are formed in the surface layer (2), a sound-absorbing layer (4) is arranged between the base layer (1) and the surface layer (2) and is made of sound-absorbing polyurethane foam, the base layer (1) is made of fabric, and the fabric is formed by tightly combining a layer of silver fiber fabric and a layer of bamboo charcoal fiber fabric. According to the sound-absorbing, radiation-proof, antibacterial and deodorant decorative film for the wall, the micropores are formed in the surface layer of the decorative film, the sound-absorbing layer is arranged between the base layer and the surface layer of the decorative film and made of the sound-absorbing polyurethane foam, when sound waves enter the sound-absorbing layer along the micropores, the sound waves will undergo a series of actions such as damping, reflection and friction with the sound-absorbing polyurethane foam, sound energy is converted into heat energy to be dissipated, and thus the sound absorbing effect is achieved. The sound-absorbing, radiation-proof, antibacterial and deodorant decorative film for the wall further has the radiation-proof, antibacterial and deodorant effects.

Description

(1) Technical field [0001] The invention relates to a decorative film.
