Description
Technical field
The invention belongs to building material technical field, a kind of heat preservation and soundproof mortar and preparation method thereof is related generally to.
Background technology
Wall in hot-summer and cold-winter area Outer Protective Structure of Dwelling House, winter need to consider that heating, summer need to consider heat-insulated, moisture-proof
With the function of waterproof, as the improvement of people's living standards, it is also contemplated that the functional requirement of sound insulation.Noise is a kind of environmental pollution
Source, and most wall cannot all meet the requirement of sound insulation, be impacted to the life and privacy of user, wherein air-borne noise
Become troubling problem via the propagation on indoor wall and floor from adjacent space with impact noise.It is high in the density of population
City, since many residents stay in high-rise concrete structure, noise problem is even more serious.Domestic dedicated pugging is simultaneously
It is rare, thermal insulation mortar is mostly used greatly to replace.Therefore, in current Residence Design, construction and finishing, it is in the urgent need to address live
Requirement of the residence wall to sound insulation, and still need to ensure the heat-insulating property that wall is basic.
Publication number CN105330221A proposes a kind of compounding fiber pugging, is by the raw material system of following weight parts
：Corncob 3-5, polyvinyl alcohol 2-3, alumina silicate fibre 1-3, guar gum 1-2, soybean fiber 1.5-1.8, mineral wool fiber
3-4, lithium carbonate 0.6-0.8, zinc molybdate 1.5-2.8, turkey red oil 1-3, tween 0.2-0.5, flyash 10-18, sugar calcium 1-
2, coating slag 8-12, cement 30-40, appropriate amount of water.Above-mentioned pugging is more focused on heat-insulating property at being grouped as, for sand
The sound insulation value research of slurry is few, and soundproof effect is bad.
Publication number CN102701677A proposes a kind of energy-saving sound insulation mortar, and composition quality proportioning is portland cement
30%-40%, floating bead 30%-45% regenerate EPS 2%-4%, waste Crumb rubber 7%-10%, redispersable latex powder 0.5%-
2%, cellulose ether 0.4%-3%, fiber 0.5%-2%, pottery sand 12%-18%.The energy-saving sound insulation mortar meets house wall
The functional requirement of energy-saving, but its soundproof effect is unsatisfactory.
Therefore, be badly in need of at present a kind of soundproof effect it is good and ensure wall heat-insulating property heat preservation and soundproof mortar.
Invention content
The purpose of the present invention is to provide that a kind of soundproof effect is good and guarantee wall for deficiencies of the prior art
Heat-insulating property heat preservation and soundproof mortar.
To achieve the above object, technical solution provided by the invention is as follows：
A kind of heat preservation and soundproof mortar, includes the component of following parts by weight：
250-300 parts of cement；
100-140 parts of flyash；
80-120 parts of waste rubber powder；
80-120 parts of glass bead；
80-120 parts of lightweight volcanic ash；
400-440 parts of fine sand；
10-15 parts of bentonite；
10-50 parts of diatomite；
Damp 30-50 parts of filler；
8-12 parts of redispersable latex powder；
1-10 parts of starch ether；
1-10 parts of cellulose ether；
1-10 parts of PP fibers；
The waste rubber powder grain size is 1-5mm, bulk density 1.2-2.0g/cm3；
Glass bead rate of closed hole >=96%, grain size 1.5-3.5mm, unit weight 100-200kg/m3；
The starch ether, cellulose ether mass ratio be 2-7:5；
The damping filler, diatomite, bentonitic weight ratio are 3-5:2-3:1.
Flyash is directly used in as admixture in mortar, can be improved the workability of mortar, be saved material, and mortar is reduced
Cost reduces environmental pollution.Dynamic modulus of elasticity, intrinsic frequency and the ultrasonic wave that waste rubber powder can obviously reduce cement mortar pass
Speed is broadcast, but the intensity of mortar can be reduced accordingly.The hole-closing structure of glass bead makes to have stored a large amount of still airs in mortar,
The thermal coefficient of still air is 0.026W/m.k, thus mortar is made to constitute strong gas phase insulation.In addition, hole-closing structure has
