Description

Dampproofing fire-resistant environmental protection deadening felt

Technical Field

The utility model relates to a soundproof cotton field especially relates to a dampproofing fire-resistant environmental protection deadening felt.

Background

The water pipes of a plurality of buildings in the building are vertically arranged outside the building body, and the water pipes are mainly metal pipes and nonmetal pipes, so that the sound insulation and heat insulation effects are poor. In air conditioner, ventilation system, the noise of fan can be passed to indoor along the tuber pipe, to place pipelines such as house or office building, hotel, official working, public, for indoor water supply and drainage pipe, outdoor water supply and drainage pipe etc. whenever there is flowing water to pass through, the noise that produces often makes people intolerable, usually adds to connect the silencer to reduce the noise on the pipeline. The hot water pipeline is basically insulated in a mode that sponge materials are coated on the outer side of the pipeline, and the like, and because the outer side of the sponge lacks structural support, a special hot water pipeline channel needs to be dug underground when the hot water pipeline is laid, or a large cement pipeline is used as the hot water pipeline channel. The cement pipe has high manufacturing cost, is inconvenient to carry and has poor sound insulation effect. The most effective method in terms of noise control is to control the sound power of the noise source as much as possible, and take sound insulation and silencing measures on the propagation path to control the influence of noise.

Previously filed by the present company with the application numbers: chinese utility model patent of CN201620786542.0 discloses a dampproofing fire-resistant environmental protection acoustic celotex pipe, including half pipe, buckle and draw-in groove seat, half intraductal portion is provided with environmental protection damping sound insulation glue film, and the outside on environmental protection damping sound insulation glue film is provided with sound insulation and heat insulation aluminium cortex, and sound insulation and heat insulation aluminium cortex's outside is provided with the sound absorbing layer, and the outside on sound absorbing layer is provided with the decoration outer tube, and the edge of half pipe is provided with the connecting block, is provided with below the connecting block the buckle is provided with below the buckle the draw-in groove seat.

The mounting brings the trouble for the construction of sound-proof tube, need avoid the mounting through fluting or cutting the sound-proof tube in the work progress. Simultaneously, the soundproof pipe should come the customization of different diameter size according to the different specification sizes of the pipeline of parcel to give sound insulation, still need measure the required quantity of various different specification soundproof pipes in advance before the construction, has increased the construction volume. If the residual sound insulation pipe after cutting is used in subsequent construction, the sound insulation pipe can have obvious connection, so that the integrity of the sound insulation pipe is lost, and the appearance is deficient. Therefore, the residual sound insulation pipes in each construction become leftover materials, cannot be reused, has serious waste phenomenon and increases the cost of raw materials. The construction of the hard sound insulation pipe is inconvenient, more powder can be generated during cutting, the construction site is polluted, the cutting workload is not small, the construction amount of constructors is increased, and the construction period is prolonged.

The application numbers are: the utility model discloses a multi-functional ageing resistance heat preservation deadening felt in CN 201320470108.8's the chinese utility model patent, what adopted is soft deadening felt, comprises deadening felt layer 2, and its characteristics are compound at the surface of deadening felt layer 2 has aluminium foil layer 5, and from last to having set gradually PET layer 4, PVC layer 3 down between deadening felt layer 2 and aluminium foil layer 5, have sponge layer 1 in the compound of the bottom surface of deadening felt layer 2. However, this solution has the following technical drawbacks. Arranging an aluminum foil layer 5 on the outermost layer for protecting the sound-insulating felt layer 2 positioned on the lower layer; this technical scheme propaganda is that the multi-functional ageing resistance that is used for heat preservation sound-proof deadening felt such as pipeline, but in the actual production application, the aluminium foil layer if set up in outmost, receives slight of external force and collides with and can make the aluminium foil layer appear sunken in the construction and use in-process, and then influences beautifully. If meet sharp-pointed article still easy emergence damage, damaged aluminium foil layer can't protect the deadening felt, when meetting the rainwater and soaking and erodeing make the deadening felt to rise brokenly easily, the ageing of the deadening felt of acceleration. Even if the aluminum foil layer is well protected in the installation and use process, the aluminum foil layer can be corroded and oxidized by oxygen after being used for a period of time, and becomes white and flower, so that the light sensation is influenced.
