Problems solved by technology

Although the use of floating floor slabs can meet the building sound insulation index, it has the disadvantages of complex construction procedures, long construction period, and high cost, which is limited in promotion and use. At present, only a few high-end buildings are used as floating floor slabs.

Embodiment Construction

[0023] 1. The making of surface course: described surface course is cement mortar surface course. Portland cement with a strength of 42.5MPa is used for cement, and fine sand or medium sand is used for sand. Put 3kg of cement and 6kg of medium sand into the mixer and stir, and at the same time, spray 1.5kg of water into the mixture of cement and sand to obtain the surface layer slurry. Pour the surface layer slurry to an area of ​​0.5m 2 In the mould, lay a layer of graticule in the surface layer, then flatten it and press it to a thickness of 10mm.

[0024] 2. Production of sound insulation layer:

[0025] The materials are taken according to the following proportions by weight: 0.15 kg of polystyrene particles with a particle size of 2.5, 0.15 kg of polymer binder, 2.25 kg of cement, 0.24 kg of fly ash, and 0.21 kg of expansion agent. Weigh the polymer binder rubber powder, cement, fly ash and expansion agent, mix and stir evenly, add water to make slurry, wherein the wei...

Abstract

The invention provides a method for processing a soundproof cushion board for a floor, which comprises processes of manufacturing a surface layer and a soundproof layer, wherein the surface layer is made of cement mortar; the soundproof layer is formed by pressing a slurry mixture wrapped on the surface of polyphenyl granules serving as a main material, wherein the slurry mixture comprises high polymer adhesive, cement, fly ash and swelling agent; and then the surface layer and the soundproof layer are pressed and shaped. The method has the advantages of having simple operation and low cost of required raw materials, reducing the production cost, and effectively solving the problem of poor sound insulation of hard tiles of a concrete floor.

Description

technical field [0001] The invention relates to a method for manufacturing a sound-insulating backing plate for floor slabs, and belongs to the field of processing and manufacturing of building materials. Background technique [0002] Hard floor tiles such as stone and ceramic tiles have the advantages of beautiful surface, easy cleaning, and wear resistance. Many residents are willing to use them in the decoration of residential floors, especially living room floors. However, after ordinary reinforced concrete floors are directly paved with stone and ceramic hard floor tiles, the weighted impact sound pressure level of the floor is usually about 80dB, which does not meet the requirements of the national standard "Code for Residential Buildings" (GB 50368-2005). The weighted impact sound pressure level should not exceed the requirement of 75dB. [0003] At present, if the hard floor tiles of stone and ceramics are to be paved on the ground of residential buildings, and the ...
