Abstract
The utility model relates to a kind of polyurethane rubber sound insulation isolation cushion, is mainly used in the sound insulation shock insulation of the central air conditioner rooms such as office premises.It is characterized in that: described isolation cushion is upper and lower double-layer structure, upper strata is surface layer (2), and lower floor is bottom (1), and the material of described surface layer (2) and bottom (1) is waste polyurethane rubber grain, is evenly equipped with some through holes (3) on described bottom (1).The utility model polyurethane rubber sound insulation isolation cushion, adopts the preparation of waste polyurethane rubber grain, and cost is low, and after particle compacting, forms space net structure, and space is large, good springiness, and sound-absorbing effect is strong, good damping effect; At bottom, set up through hole, further improve sound-absorbing effect and damping effect; Top layer adopts colored waste polyurethane rubber grain, and identification is high and attractive in appearance, and in addition, through hole is not offered on top layer, can prevent that the cement in concrete from will pour into, and guarantees elasticity.
Description
Technical field
The utility model relates to a kind of polyurethane rubber sound insulation isolation cushion, is mainly used in the sound insulation shock insulation of the central air conditioner rooms such as office premises.
Background technology
The sound insulation shock insulation of central air-conditioning is the critical problem in its installation process, in order to reduce as much as possible noise and vibration, on the ground of the machine room of the central air-conditioning of high-grade office building, all carries out specially treated.Ground adopts the concrete base of precoating, and then lays Rubber shock-absorbing pad, then the three-tier architecture of fluid concrete surface layer, and the monolithic construction of the Rubber shock-absorbing pad using in this kind of structure for producing with virgin rubber without net structure, attract weak effect, and price is high in rubber.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and good, the low-cost polyurethane rubber sound insulation of a kind of sound-absorbing effect isolation cushion is provided.
The purpose of this utility model is achieved in that a kind of polyurethane rubber sound insulation isolation cushion, described isolation cushion is upper and lower double-layer structure, and upper strata is surface layer, and lower floor is bottom, the material of described surface layer and bottom is waste polyurethane rubber grain, is evenly equipped with some through holes on described bottom.
Described surface thickness is 3-8mm, and preferred thickness is 5mm; Described underlayer thickness is 40-50mm, and preferred thickness is 45mm.
Described surface layer is that colored waste polyurethane rubber grain compacting forms.
The beneficial effects of the utility model are:
The utility model polyurethane rubber sound insulation isolation cushion, adopts the preparation of waste polyurethane rubber grain, and cost is low, and after particle compacting, forms space net structure, and space is large, good springiness, and sound-absorbing effect is strong, good damping effect; At bottom, set up through hole, further improve sound-absorbing effect and damping effect; Top layer adopts colored waste polyurethane rubber grain, and identification is high and attractive in appearance, and in addition, through hole is not offered on top layer, can prevent that the cement in concrete from will pour into, and guarantees elasticity.
During laying, waterproof nylon layer is laid on its surface, can further prevent going deep into of cement paste, brings into play to greatest extent sound-absorbing, the shock-absorbing function of sound insulation isolation cushion.
accompanying drawing explanation:
Fig. 1 is the section structure schematic diagram of the utility model polyurethane rubber sound insulation isolation cushion.
Wherein:
Bottom 1, surface layer 2, through hole 3.
The specific embodiment
As Fig. 1, the utility model relates to a kind of polyurethane rubber sound insulation isolation cushion, and it is bottom 1 and surface layer 2 double-deckers, and described surface layer 2 thickness are 3-8mm, take 5mm as best, and surface material is made by waste polyurethane rubber grain; Described bottom 1 also has waste polyurethane rubber grain to make, and thickness is 40-50mm, is preferably 45mm, and described bottom 1 is evenly equipped with some through holes 3 from top to bottom.
For aesthetic and laying are to be easy to distinguish, bottom is different with surface material color, and top layer adopts colored waste polyurethane rubber grain.
Using method: while laying in central air conditioner room bottom surface, first lay bottom concrete, then lay the utility model polyurethane rubber sound insulation isolation cushion, the bottom of polyurethane rubber sound insulation isolation cushion is downward, surface layer upwards, on the surface layer of polyurethane rubber sound insulation isolation cushion, lay again waterproof nylon layer, finally re-lay a layer concrete.
Adopt the preparation of waste polyurethane rubber grain, cost is low, and after particle compacting, forms space net structure, and space is large, good springiness, and sound-absorbing effect is strong, good damping effect; At bottom, set up through hole, further improve sound-absorbing effect and damping effect; Top layer adopts colored waste polyurethane rubber grain, and identification is high and attractive in appearance, and in addition, through hole is not offered on top layer, can prevent that the cement in concrete from will pour into, and guarantees elasticity.
During laying, waterproof nylon layer is laid on its surface, can further prevent going deep into of cement paste, brings into play to greatest extent sound-absorbing, the shock-absorbing function of sound insulation isolation cushion.
