House sound insulation floor and preparation method thereof

Abstract

The invention belongs to the field of house floors, and relates to a house sound insulation floor and a preparation method thereof. The invention provides the house sound insulation floor. The house sound insulation floor comprises a bottom sound insulation layer, 2-3 middle sound absorption layers and a surface sound attenuation layer. According to the house sound insulation floor, through a large amount of micropores and a large amount of rubber powder of the surface sound attenuation layer, mechanical collision sound generated on the ground is reduced, the decibel of the sound is reduced, and the sound is eliminated from the source; sound is isolated and reflected through compact layers of the middle sound absorption layers, and most of sound can be eliminated through the 2-3 middle sound absorption layers due to the sound absorption effect of foaming layers; and the bottom sound insulation layer is more compact, is provided with no micropores in the middle, and can isolate or reflect sound so as to prevent the sound from being transmitted to a lower floor. The preparation method for the sound insulation floor is simple, raw materials are easy to obtain, and in addition, the whole preparation process is free of environmental pollution.

Description

technical field [0001] The invention belongs to the field of house floors, and relates to a house soundproof floor and a preparation method thereof. Background technique [0002] The existing residential buildings have the disadvantage of poor sound insulation between the upper and lower floors. It is difficult to achieve sufficient sound insulation effect only by relying on the cement board of the floor and the floor laid on the cement board, and the traditional products only distinguish between high-frequency noise and low-frequency noise. , different enough to block the noise of each frequency, thereby affecting the quality of life among the residents; the current working hours are different, and the sound of walking upstairs at night has a serious impact on the downstairs; especially for families with children, the children play ball upstairs, run If there is any movement, it will bring a lot of noise downstairs, which will affect the sleeping downstairs.

AI Technical Summary

Problems solved by technology

[0004] In view of the poor sound insulation of buildings at the present stage and the existing sound insulation materials that cannot meet the sound insulation requirements, the present invention provides a sound insulation floor for houses, which includes a bottom sound insulation layer, a middle sound absorption layer of 2-3 layers, and a surface sound attenuation layer. A large number of micropores and a large amount of rubber powder in the sound-absorbing layer of the surface layer can reduce the sound of mechanical collision on the ground, reduce the decibel of the sound, and eliminate the sound from the source; through the dense layer of the sound-absorbing layer in the middle, the sound is isolated and reflected, foaming Layer sound absorption, through the middle sound absorption layer of 2-3 layers, most of the sound can be eliminated; the bottom sound insulation layer is denser, without micro holes in the middle, which can isolate or reflect the sound and prevent it from passing to the lower floor
