Description

Build flooring Multifunctional sound insulation vibration damping composite material and its production technology
Technical field:
The invention belongs to new building material technical field, in particular to a kind of building flooring Multifunctional sound insulation vibration damping composite wood Material, further relates to the production technology of the material.
Background technique:
It is well known that sound source, in the vibration of object, vibration propagates be formed sound wave in air, and when sound wave incident arrives When wall or floor, wall or floor will be made also to generate vibration and to external radiation.Noise is then that sounding body does random vibration The sound issued when dynamic.In daily life, most common is exactly that resident upstairs walks about (especially hard footwear is with such as high-heeled shoes), child Son play it is noisy run, behavior usual in the life such as household is moved, give one impact force of floor, this impact force is enough to produce floor Raw vibration.If the effectiveness in vibration suppression of floor is bad, sound will be transmitted in the family of resident downstairs by floor, wall, be caused Either large or small noise and make troubles to other people, Building Indoor Environment is frequently subjected to the interference of this noise like." green building is commented Price card is quasi- " GB/T50378, " Code for sound insulation design of civil buildings " GB50118 be to house, school, hospital, hotel, office and quotient Noise control in the six classes building such as industry building is put forward new requirements, the air-borne sound sound insulation of floor and strike note sound insulation property All done specified in more detail again, wherein residential housing bedroom, living room point family floor weighted hit a sound pressure level and should be not more than 75dB.In general, Reinforced Concrete Materials has good air-borne sound sound insulation property, the typical armored concrete of 120mm thickness Floor air-borne sound oise insulation factor is about 45dB, and it is about 80- that the weighted of 120mm thickness armored concrete point family floor, which hits sound pressure level, The requirement of relevant criterion is not achieved in 82dB.

Specific embodiment:
Specific embodiments of the present invention will be described in detail below, it is to be understood that protection scope of the present invention is not had The limitation of body embodiment.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members Part or other component parts.
A kind of building flooring Multifunctional sound insulation vibration damping composite material, including basal layer 1 and it is placed in basal layer two sides table The softer, elastic damping layer 3 in face is provided with hollow glass microbead superposed layer 2, hollow glass between basal layer and the damping layer of two sides Glass microballon superposed layer is several hollow glass microbead 2-1 uniform curing in the glue-line that pressure sensitive adhesive is formed.Hollow glass microbead is outstanding It floats in pressure sensitive adhesive, since hollow glass microbead 2-1 quality is light, it will not settle or arbitrarily run, just as being suspended in glue, An excellent sound-insulating layer is just formed after waiting glue solidification.Pressure sensitive adhesive surface after solidification has viscosity, passes through cold pressing Directly paste basal layer.
It is to be understood that using softer, elastic damping layer 3 and 3 both side surface of softer, elastic damping layer can also be placed in Basal layer 1, this reversed order is in the field of business to belong to more typical application method.
If the film surface of selection, without viscosity, glue-line is laid on the surface of basal layer or buffer layer, basal layer and Buffer layer, which is mutually bonded, can be realized the compound of material.
Glue-line can be formed with pre-production or be coated in basis by the adhesive of liquid premix hollow glass microbead Layer or vibration damping layer surface are formed.
Basal layer or the adhesive surface of damping layer are that smooth surface is perhaps viscous when basal layer or damping layer with concaveconvex structure When veneer has concaveconvex structure, the adhesive for premixing hollow glass microbead is coated in basal layer or damping layer and flows into concave-convex knot Form that a upper surface is smooth, lower surface is non-smooth glue-line in structure, this is to increase the thickness of glue-line and to increase heat anti- Penetrate the effect of harmony wave reflection.
There are two types of these concaveconvex structures, and one is the artificial later periods to form, such as the groove that surface precreping is formed, such as subtracts Shake layer fin 3-1, the open-celled structure of section after damping layer groove 3-2 or foamed material are cut, another kind be material itself from Band, such as the tissue space between loose fiber class material.
