Problems solved by technology

[0002] With the continuous acceleration of the urbanization process, the noise pollution is also becoming more and more serious. In order to ensure people's good living and working environment and effectively cut off the noise, the common method is to use cement and glass walls to play the role of isolation, but these materials are not only The quality is heavy and the sound insulation effect is not good, so it is difficult to meet people's requirements for noise isolation

Embodiment 1

[0030] The environmental sound insulation board is composed of a surface layer and a base layer. The surface layer is a mortar with a thickness of 0.7-2cm. The base layer includes two sound insulation layers; cm foam polyethylene material. Conical sound-absorbing holes are arranged on the surface of the sound-insulating layer, wherein the radius of the bottom surface of the conical sound-absorbing holes is 0.5-1.2 cm. The height of the conical sound-absorbing hole groove is 0.3-0.5 centimeters.

Embodiment 2

[0032] The preparation method of sound insulation layer, this method comprises the following steps:

[0033] (1) Weigh 60kg of polystyrene, 20kg of polyethylene, 5kg of glass fiber, 3kg of fly ash, 0.5kg of calcium carbonate, 0.8kg of tris(2.4-di-tert-butylphenyl) phosphite, and diacyl sebacic acid Hydrazine 0.2kg, benzophenone 0.2kg;

[0034] (2) Put the above components into a high-pressure homogenizer, stir at 21.5MPa and 65°C for 10 minutes, and press to form a sound-insulating layer.

Embodiment 3

[0036] The preparation method of sound insulation layer, this method comprises the following steps:

[0037] (1) Weigh 75kg of polystyrene, 35kg of polyethylene, 6kg of glass fiber, 5kg of fly ash, 1.2kg of calcium carbonate, 2kg of tris(2.4-di-tert-butylphenyl) phosphite, and sebacic acid dihydrazide 0.02kg, benzophenone 0.8kg;

[0038] (2) Add the above components into a high-pressure homogenizer, stir at 22MPa and 70°C for 20 minutes, and press to form a sound-insulating layer.

Abstract

The invention discloses preparation methods for an environment-friendly sound insulation board and a sound insulation layer. The environment-friendly sound insulation board is composed of a surface layer and a base layer which comprises at least two sound insulation layers. The surfaces of the sound insulation layers are provided with conical sound absorption hole grooves. Foamed polyethylene materials with the thickness being 0.5-1 cm are arranged between the sound insulation layers. The invention further provides the preparation method for the sound insulation layer. The preparation method for the sound insulation layer comprises the following steps that components are added into a high-pressure homogenizer and stirred for 10-20 min under the pressure of 21.5-22 MPa and at the temperature of 65-70 DEG C; and pressing forming is conducted to obtain the sound insulation layer.

Description

technical field [0001] The invention belongs to the field of sound-insulating materials, in particular to an environment-friendly sound-insulating board and a method for preparing a sound-insulating layer. Background technique [0002] With the continuous acceleration of the urbanization process, the noise pollution is also becoming more and more serious. In order to ensure people's good living and working environment and effectively cut off the noise, the common method is to use cement and glass walls to play the role of isolation, but these materials are not only The quality is heavy and the sound insulation effect is not good, so it is difficult to meet people's requirements for noise isolation. [0003] The sound itself is generated by the vibration of the air, and the thicker the material, the better the sound insulation effect. How to choose materials more effectively to control the noise volume has become a concern of people. Contents of the invention [0004] In v...
