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

Embodiment 1

[0025] A preparation method of a house soundproof floor, comprising the following steps:

[0026] (1) Mix 10kg of ultra-fine cement, 30kg of sand and 5kg of building rubber powder evenly, add an appropriate amount of water, spread it on the ground, beat it with a mortar board for many times, eliminate air bubbles, and solidify to form a 3mm-thick bottom sound insulation layer;

[0027] (2) Mix 40kg of cement, 5kg of building rubber powder, 8kg of rubber powder, 15kg of expanded perlite, 10kg of mineral wool, and 1.5kg of 40% hydrogen peroxide; after mixing evenly, add an appropriate amount of water and lay it on the bottom sound insulation layer, and lay it on the top. The upper layer of glass fiber cloth is rolled with a roller several times to make the surface bubbles volatilize to form a dense layer, which is solidified, and the thickness of the dense layer is 1.5 mm; repeat the above steps once to form two layers of 5 mm thick intermediate sound-absorbing layer;

[0028] (...

Embodiment 2

[0030] A preparation method of a house soundproof floor, comprising the following steps:

[0031] (1) Mix 10kg of ultra-fine cement, 40kg of sand and 5kg of building rubber powder evenly, add an appropriate amount of water, spread it on the ground, beat it with a mortar board for many times, eliminate air bubbles, and solidify to form a bottom sound insulation layer with a thickness of 5mm;

[0032] (2) Mix 40kg of cement, 5kg of building rubber powder, 12kg of rubber powder, 10kg of expanded perlite, 5kg of mineral wool, and 0.5kg of foaming agent; after mixing evenly, add an appropriate amount of water, spread it on the bottom sound insulation layer, and lay it on top. A layer of glass fiber cloth is rolled with a roller for many times to volatilize the air bubbles on the surface to form a dense layer, which is cured, and the thickness of the dense layer is 0.8 mm; repeat the above steps twice to form three layers of 3 mm thick intermediate sound-absorbing layers;

[0033] (...

Embodiment 3

[0035] A preparation method of a house soundproof floor, comprising the following steps:

[0036] (1) Mix 10kg of ultra-fine cement, 35kg of sand, and 5kg of building rubber powder evenly, add an appropriate amount of water, spread it on the ground, beat it with a mortar board for many times, eliminate air bubbles, and solidify to form a 4mm-thick bottom sound insulation layer;

[0037] (2) Mix 40kg of cement, 5kg of building rubber powder, 10kg of rubber powder, 12kg of expanded perlite, 8kg of mineral wool, and 1.0kg of 40% hydrogen peroxide; after mixing evenly, add an appropriate amount of water and lay it on the bottom sound insulation layer, and lay it on the top. The upper layer of glass fiber cloth is rolled with a roller for many times to volatilize the air bubbles on the surface to form a dense layer, which is cured, and the thickness of the dense layer is 1.0 mm; repeat the above steps twice to form three layers of 4 mm thick intermediate sound-absorbing layers;

Abstract

The invention belongs to the field of house floors, and relates to a house soundproof floor and a preparation method thereof. The building sound insulation floor provided by the invention comprises a bottom sound insulation layer, 2-3 middle sound absorbing layers, and a surface sound absorbing layer. A large number of micropores and a large amount of rubber powder in the surface sound absorbing layer can reduce the mechanical collision sound generated on the ground. Reduce the decibel of the sound and eliminate the sound from the source; isolate and reflect the sound through the dense layer of the middle sound-absorbing layer, and the sound-absorbing effect of the foam layer can eliminate most of the sound through the middle sound-absorbing layer of 2-3 layers; the bottom layer is sound insulation The layer is denser and has no micro-holes in the middle, which can isolate or reflect sound and prevent it from being transmitted to the lower floors; the preparation method of the sound insulation floor of the present invention is simple, the raw materials are easily obtained, and the whole preparation process does not pollute the environment.

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 only by relying on the cement board on the floor and the floor laid on the cement board, and traditional products only distinguish between high-frequency noise and low-frequency noise. , different and fully block the noise of various frequencies, thus affecting the quality of life among residents; at this stage, the working hours are different, and the sound of walking upstairs at night has a serious impact on the downstairs; especially in families with children, children play ball and run upstairs. If it moves, it will bring a lot of noise downstairs and affect sleep downstairs. [0003] Existing sound insulation technologies, ...
