Abstract
The invention provides a vibration-damping sound-insulation mortar which comprises the following components in parts by weight: 60-80 parts of sand, 40-60 parts of cement and 10-30 parts of granulated cork. All the components are uniformly mixed to obtain the mortar. The vibration-damping sound-insulation mortar is a powdery mortar material, and is used for construction by directly adding water and stirring on site; and the dried and solidified mortar can prevent water and cracking. The vibration-damping sound-insulation mortar can effectively reduce resonance, decreases the floor resonance effect, increases the transmission loss, and enhances the sound insulation factor by obviously controlling the resonant frequency of the original substrate, thereby achieving the weighting normalized impact pressure level Ln, w=55-65dB. The vibration-damping sound-insulation mortar reduces the occupation of the sound-insulation layer in the storey height, and greatly saves the construction cost. The vibration-damping sound-insulation mortar is the most convenient vibration-damping material in the existing floating floor slab materials, and effectively overcomes the defect of high cracking tendency in the protective layer of the traditional floating construction and the defect of high damage tendency of the crossed operations in the construction process.
Description
Technical field
The present invention relates to a kind of mortar, particularly relate to a kind of vibration damping sound insulation mortar and preparation method thereof and using method.
Background technology
As everyone knows, sound source is in the vibration of object, and vibration is propagated in atmosphere and just defined sound wave, and when sound wave incident is to body of wall or floor, body of wall or floor will be made also to produce vibrate and to external irradiation.In daily life, modal is exactly that resident family is upstairs when walking, step can give floor surging force, this surging force is enough to make floor produce vibration, if the effectiveness in vibration suppression of floor is bad, footsteps will be delivered in the family of resident family downstairs by floor, wall, causes either large or small influence of noise.
Cement is widely used at building engineering field as a kind of hydraulic cementing materials, and its main characteristic is the plasticity-had after adding suitable quantity of water, can not only harden in atmosphere, also can harden in water.Cement is specially adapted to manufacture concrete, and is widely used in the occasion such as road surfacing, building construction.Existing material of construction as sand-cement slurry there is easy construction, intensity high is widely used, but along with the raising of customer need, requirement for material of construction sound-proofing properties is more and more higher, sound-proof material general requirement density is high, thickness is large, composite architectural materials density is in the market less, rear soundproof effect of having constructed is not obvious, in order to reach the object of sound insulation, often through installing Sound-proof material or pugging realization additional at building wall.Now many employing floating build floors sound insulating construction, traditional floating build floor structure is on reinforced concrete floor, pad the resilient sound isolation layer of one deck based on mineral wool, then repaves flooring (armored concrete, finish coat)., traditional floating build floor way protective layer easily ftractures and in construction process, cross-operation is easy to damaged, add pugging taking story height, and pugging cost is high, and adds building operation difficulty.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of vibration damping sound insulation mortar and preparation method thereof and using method are provided.Vibration damping defening effect is good, decreases pugging taking story height, effectively avoids floating build floor way protective layer easily to ftracture and in construction process, cross-operation is easy to damaged problem.
First aspect of the present invention is to provide a kind of vibration damping sound insulation mortar, and according to weight parts, its component comprises:
Husky 60 ~ 80 parts;
Cement 40 ~ 60 parts;
Granulated cork 10 ~ 30 parts.
Further, according to weight parts, the component of described vibration damping sound insulation mortar comprises:
Husky 65 ~ 75 parts;
Cement 45 ~ 55 parts;
Granulated cork 15 ~ 25 parts.
Further, according to weight parts, the component of described vibration damping sound insulation mortar comprises:
Husky 70 parts;
Cement 50 parts;
Granulated cork 20 parts.
Second aspect of the present invention is to provide the preparation method of the vibration damping sound insulation mortar described in the present invention first aspect, each component is mixed, both.
3rd aspect of the present invention is to provide the using method of the vibration damping sound insulation mortar described in the present invention first aspect, and the stirring that directly added water by the vibration damping sound insulation mortar described in the present invention first aspect is constructed.
Tool of the present invention has the following advantages:
Vibration damping provided by the invention sound insulation mortar is a kind of loose shape mortar material, and scene directly adds water and stirs construction, once i.e. waterproof, crack resistence after dry solidification; Can resonance be effectively reduced, make flooring resonance effect reduce and increase transmission loss, significantly control former base material resonant frequency and promote oise insulation factor; Follow GB/T50121-2005 standard and GB/T19889.8-2006/ISO-140-8:1997 standard detection to reach weighted standardization and clash into sound pressure levels Ln, w=55 ~ 65dB; Without the need to using sound insulation bed course, decrease sound insulation bed course to the taking of story height, save building cost greatly.Be the damping material of most convenient of constructing inside current floating build floor material, it effectively avoids the floating structure way protective layer of building of tradition and easily to ftracture and in construction process, cross-operation is easy to damaged weak point.
