Embodiment 1
[0028] This embodiment provides a kind of sound insulation mortar, and this sound insulation mortar is made by mixing the raw materials comprising the following parts by weight:
[0029] 500 parts of cement, 450 parts of elastic damping aggregate, 45 parts of viscosifying additive, 270 parts of river sand, 1 part of water-retaining thickening additive, and the water-binder ratio of the sound-proof mortar is 1:0.3; the cement uses 42.5R silicic acid salt cement.
[0030] Wherein, the elastic damping aggregate includes rubber powder and rubber granules, the mass ratio of rubber powder and rubber granules is 2.5:1; the mesh number of rubber powder is 40-120, and the mesh number of rubber granules is 1-3;
[0031] The main components of rubber powder and rubber granules are natural rubber, butadiene rubber and styrene-butadiene rubber;
[0032] The mesh number of river sand is 40-70;
[0033] The tackifier is dispersible latex powder;
[0034] The water-retaining thickener is a...
Embodiment 2
[0036] This embodiment provides a kind of sound insulation mortar, and this sound insulation mortar is made by mixing the raw materials comprising the following parts by weight:
[0037] 500 parts of cement, 450 parts of elastic shock-absorbing aggregate, 45 parts of thickening additive, 270 parts of river sand, 1 part of water-retaining thickening aid, 1 part of nano-alumina, 3 parts of polyether ether ketone powder, and sound-proof mortar The water-cement ratio is 1:0.3; the particle size of polyetheretherketone powder is 120-150μm, and the cement is 42.5R Portland cement.
[0038] Wherein, the elastic damping aggregate includes rubber powder and rubber granules, the mass ratio of rubber powder and rubber granules is 2.5:1; the mesh number of rubber powder is 40-120, and the mesh number of rubber granules is 1-3;
[0039] The mass ratio of polyetheretherketone powder and nano-alumina is 3:1;
[0040] The mesh number of river sand is 40-70;
[0041] The tackifier is dispers...
Embodiment 3
[0044] The difference between Example 3 and Example 2 is that the content of each component and the physical parameters of the sound insulation mortar are different, see Table 1 for details; wherein the water-retaining thickener is hydroxyethyl methyl cellulose ether.
