Abstract

The invention relates to a composite noise-reduction muffler plate. The muffler plate comprises a flame-retardant gypsum board A, a sound-absorbing non-woven cloth A, a flame-retardant sound-absorbing porous plate A, a sound-absorbing cotton layer, a flame-retardant sound-absorbing porous plate B, a sound-absorbing non-woven cloth B and a flame-retardant gypsum board B which are sequentially stacked. The flame-retardant gypsum board A, the sound-absorbing non-woven cloth A, the flame-retardant sound-absorbing porous plate A, the sound-absorbing cotton layer, the flame-retardant sound-absorbing porous plate B, the sound-absorbing non-woven cloth B and the flame-retardant gypsum board B are closely laminated to form the whole composite noise-reduction muffler plate. The whole composite noise-reduction muffler plate is composed of multiple layers of composite materials, is convenient to assemble and maintain, and has the advantage of being good in noise reduction effect.

Description

technical field [0001] The invention relates to a sound-absorbing board, in particular to a multi-layer composite noise-reducing and sound-absorbing board, which belongs to the field of sound-absorbing boards. Background technique [0002] The noise-reducing shell for American-style box-type transformers is a common noise reduction device for American-style box-type transformers. It can effectively reduce the noise transmitted to the external environment when American-type box-type transformers are working. Having attention. At present, the existing noise-reducing housings, especially the noise-reducing housings for outdoor American-style box-type transformers usually have no obvious noise-reducing effect. When the American-style box-type transformer is running, the noise and vibration caused by the magnetic hysteresis of the iron core will be transmitted to the shell body through the base, so that the American-style box-type transformer will use noise reduction to become a...
