Sound-absorbing wall space decoration film capable of effectively absorbing indoor radiation waves

Abstract

The invention relates to a decoration film, in particular to a sound-absorbing wall space decoration film capable of effectively absorbing indoor radiation waves. The sound-absorbing wall space decoration film comprises a base layer (1) and a surface layer (2) and is characterized in that the surface layer (2) is provided with micro-pores (3), a sound-absorbing layer (4) made of sound-absorbing polyurethane foams is arranged between the base layer (1) and the surface layer (2), and a wave-absorbing layer (5) is fixedly arranged on the back surface of the base layer (1). According to the arrangement that micro-pores are formed in the surface layer and the sound-absorbing layer made of the sound-absorbing polyurethane foams is arranged between the base layer and the surface layer, when entering the sound-absorbing layer along the micro-pores, sound waves are involved in a series of actions of damping, reflection and friction with the sound-absorbing polyurethane foams, sound energy can be converted into heat energy to be consumed, and thus sound-absorbing effect can be achieved. In addition, the indoor radiation waves can be effectively absorbed.

Description

(1) Technical field [0001] The invention relates to a decorative film. (2) Background technology [0002] With the improvement of people's living standards and the development of the cultural industry, people are willing to go to the opera house to listen to operas and go to the cinema to watch movies. However, due to the large size of the theater and the long reverberation time in the opera house and cinema, the sound clarity becomes poor, which affects People listen to opera and watch movies. Therefore, it is necessary to do sound-absorbing treatment on the walls of opera houses and cinemas. For some movie theaters that have been built, it is difficult to do sound-absorbing treatment, and they need to be renovated. The project is large, time-consuming and expensive. And can not effectively absorb indoor radiation waves. (3) Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and provide a wall sound-absorbing...
