Embodiment 1

[0038] This embodiment provides a kind of sound insulation mortar, is made up of the following raw materials by weight percentage:

[0039] Cement: 20%;

[0040] Elastic sound insulation particles: 20%;

[0041] Sand: 25%;

[0042] Special glue: 15%;

[0043] Water: 20%.

[0044] The sound insulation mortar prepared according to this ratio is used for the impact sound test experiment. The impact sound test experiment needs to be carried out in the sound emitting room and the receiving room. Two rooms, the room on the upper floor is the sounding room, and the room on the lower floor is the receiving room. Spread 10mm thick soundproofing mortar on the floor of the sounding room to form a 10mm thick soundproofing mortar layer. The impactor is placed on the sound-proof mortar layer, and the microphone is placed on the floor of the receiving room. According to the records in "GB / T 19889.7-2005 Acoustic Building and Building Component Sound Insulation Measurement Part 7: On-si...

Embodiment 2

[0050] This embodiment provides another kind of sound insulation mortar, which is made up of the following raw materials by weight percentage:

[0051] Cement: 13%;

[0052] Elastic sound insulation particles: 28%;

[0053] Sand: 26%;

[0054] Special glue: 8%;

[0055] Water: 25%.

[0056] The sound insulation mortar of this embodiment was used to conduct an impact sound test experiment, and this experiment was recorded as Experiment 2. The experimental principle and experimental process of Experiment 2 are the same as those of Experiment 1. Normalized impact sound pressure level L in experiment 2 nT The relationship between it and the impact sound frequency f is shown in the table below.

[0059]

[0060] According to Table 2, it can be concluded that the sound insulation mortar layer provided by this embodiment is made into a 10mm sou...

Embodiment 3

[0062] The present embodiment provides the third kind of sound insulation mortar, which is made up of the following raw materials by weight percentage:

[0063] Cement: 13%;

[0064] Elastic sound insulation particles: 30%;

[0065] Sand: 25%;

[0066] Special glue: 12%;

[0067] Water: 20%.

[0068] The sound insulation mortar of this embodiment was used to carry out the impact sound test experiment, and this experiment was recorded as experiment 3. The experimental principle and experimental process of Experiment 3 are the same as those of Experiment 1. Normalized impact sound pressure level L in experiment 3 nT The relationship between it and the impact sound frequency f is shown in the table below.

Abstract

The invention provides sound insulation mortar, a sound insulation floor structure and a preparation method of the sound insulation mortar. The sound insulation mortar is prepared from the following raw materials in percentage by weight: 13%-20% of cement, 20%-35% of elastic sound insulation particles, 25%-40% of sand, 5%-15% of a binder for construction, and 20%-25% of water. The sound insulationfloor structure comprises a floor layer, a sound insulation mortar layer, a dry mortar layer and floor tiles which are sequentially arranged from bottom to top. The preparation method comprises the steps S1 to S4. The sound insulation mortar has good sound insulation performance, the thickness of the sound insulation mortar layer in the sound insulation floor structure can be reduced, and space is saved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sound-insulating mortar and a sound-insulating floor structure. Background technique [0002] Solid sound, that is, the energy of impact sound has little attenuation in traditional building materials, the propagation speed is faster than in the air, and the propagation distance is very long. The air sound insulation effect of the existing concrete floor is good, but for the impact sound ( The effect of solid sound) is not ideal, so the residents living in the lower floors generally cannot hear the voices of the upper residents, but the sounds of the upper residents dragging the table, children running and jumping, and heels hitting the ground have a great impact on the lower residents. In order to improve the sound insulation effect of the floor floor, a layer of sound insulation material is generally arranged in the floor floor, and the commonly used sound insula...
