Embodiment Construction

[0024] Such as Figure 1-2 As shown, a sound-insulating film-coated cotton includes glass wool 1, and the top surface and both sides of the glass wool 1 along its length direction are covered with an upper plastic film 2 and extend to the bottom surface. A through hole 4 is provided, and the glass wool can absorb sound by using the through hole. The bottom surface of the glass wool 2 along its length direction is covered with a lower plastic film 3 , and the lower plastic film 3 is covered and connected to the upper plastic film 2 by hot melt adhesive. Both ends of the upper plastic film 2 and the lower plastic film 3 along the length direction are sealed by a hot melt machine. The closed upper plastic film 2 and the lower plastic film 3 are used to block the fly generated by the glass wool during transportation or use, so as to protect the environment.

[0025] A production process of sound-insulating film-coated cotton is characterized in that: its specific steps are as fo...

Abstract

The invention discloses a sound-insulating film-coated cotton, which comprises glass wool. The top surface and both sides of the glass wool along its length direction are covered with an upper plastic film and extend toward the bottom surface. There is a lower plastic film, and the lower plastic film is covered and connected to the upper plastic film; the two ends of the upper plastic film and the lower plastic film along the length direction are sealed by a hot-melt machine. The six sides of the glass wool of the present invention are covered with a layer of plastic film, which has a certain moisture-proof effect, and can prevent a large amount of cotton wool and cotton dust from flying and polluting the environment during use, and absorbs noise by using the holes on the plastic film.

Description

technical field [0001] The invention relates to the field of sound-absorbing materials, in particular to a sound-insulating film-coated cotton. Background technique [0002] Noise directly affects people's physical and mental health and the improvement of quality of life. Being in a noisy environment for a long time will cause hearing loss and may even induce some diseases. To stay away from noise, what we can do is sound absorption and sound insulation. Glass wool has the function of sound absorption and noise reduction, but when ordinary glass wool is used, many flying hairs often appear, polluting the environment. Contents of the invention [0003] The object of the present invention is to provide a sound-insulating film-coated cotton, which solves the problem that the glass wool will produce cotton wool and cotton scraps flying and pollute the environment when it is used. [0004] In order to solve the problems of the technologies described above, the present inventio...
