Abstract
A composite silencing plate comprises a plate-shaped or a curl-shaped insulation layer, and the upper layer and the lower layer of the insulation layer are covered with packaging layers. The insulation layer is formed by bonding two or three of the three components, namely paper, fibers and asbestos with a chemical agent. The chemical agent comprises a flame-retardant agent, a dispersant agent, a waterproof agent and adhesive. Each packaging layer is made of non-woven cloth or felt. The composite silencing plate comprises a surrounding plate and an upper cover covered on the surrounding plate. The upper cover is formed by one-time cutting and is in a shape of a circle, and triangular notches are arranged in the radial direction of the upper cover. The surrounding plate is formed by one-time cutting and in a shape of a rectangle, and the length of the surrounding plate is smaller than, equal to or larger than the perimeter of the upper cover. The surrounding plate is rolled into a cylindrical shape and is fixed by magic tape arranged on the surrounding plate. The upper cover is covered on top of the surrounding plate. The composite silencing plate is low in fabrication cost, light and good in insulating, waterproof and fireproof performance. Products of the composite silencing plate are widely applicable to insulation of various machines such as automobiles and air conditioner compressors and insulation of places such as offices and places of entertainment.
Description
Technical field
The utility model relates to a kind of compound acoustical panel and goods thereof.
Background technology
The noise that is produced when reducing machine (like the compressor of automobile, air-conditioning etc.) work perhaps in order to satisfy the sound insulation needs of office space, public place of entertainment, generally can adopt acoustical panel to carry out noise reduction.Acoustical panel as shown in Figure 1, traditional, pugging are rubber layer, and the upper and lower faces of rubber layer all is covered with nonwoven fabrics or felt.
Chinese patent document number CN101852197A discloses a kind of soundproof shade for air condition compressor and manufacturing approach thereof on October 6th, 2010.Soundproof shade for air condition compressor comprises side, loam cake and the lower cover that is surrounded by sound insulation sheet material; Be provided with connecting portion between one side of loam cake and the side coboundary, on cover and be provided with two parallel otch, the end of otch is provided with the hole, is provided with the connection fastener between loam cake and the side; Be provided with VELCRO between lower cover and the side; Sound insulation sheet material comprises vulcanie plate, rubber pange layer, plastic foamed layer, rolling rubber plate and the fire-retardant nonwoven fibre layers that outside to inside is arranged in order.Utilize blimp of the present invention, cost is low, be nested on the compressor of air conditioner easily, and soundproof effect is good.The manufacturing approach of soundproof shade for air condition compressor is for earlier each layer being fit together through water-soluble viscose glue, and is die-cut then, last, is assembled into blimp.Because it mainly adopts rubber to make pugging, so the difficult reduction of the manufacturing cost of finished product, the gained finished product is heavier simultaneously, is unfavorable for the lightweight of compressor.
The utility model content
The purpose of the utility model aims to provide a kind of low cost of manufacture, light weight, and sound insulation, waterproof, compound acoustical panel and goods thereof that flameproof effect is good are to overcome weak point of the prior art.
By a kind of compound acoustical panel of this purpose design, comprise the pugging of tabular or web-like, the upper and lower surface of pugging all is coated with wrapper, and its architectural feature is that pugging is made up of two or three in paper, fiber, the asbestos, is bonded through chemical agent.
Said chemical agent is made up of fire retardant, spreading agent, water-proofing agent, bonding agent.
Said wrapper is nonwoven fabrics or felt.
A kind of goods of compound acoustical panel, its architectural feature are to comprise that coaming plate and lid connect loam cake above that.
Said loam cake is determined through disposable, and is rounded, has the breach that is triangular shape on its radial direction.
Said coaming plate is determined through disposable, and is rectangular, and its length is less than or equal to or greater than the girth of loam cake.
Said coaming plate is rolled into cylindric, and fixes through the VELCRO on it, and loam cake covers the top at coaming plate.
The pugging of the utility model complex sound insulation plate is made up of two or three in paper, fiber, the asbestos, and is bonded through chemical agent, and it is low to have cost of manufacture with the goods of its making; Light weight; Sound insulation, waterproof, the characteristics that flameproof effect is good, its product-use is extensive, can be applicable to the sound insulation of all kinds of machines; Like sound insulation of automobile, compressor of air conditioner and office space, public place of entertainment etc.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 2, this compound acoustical panel comprises the pugging 2 of tabular or web-like, and the upper and lower surface of pugging all is coated with wrapper 1, and its pugging 2 can be made up of two or three in paper, fiber, the asbestos as required, passes through chemical agent and is bonded.Described paper, fiber, asbestos can be recovery article, and not only cost is low, and environmental protection more, help protecting environment.
Chemical agent is made up of fire retardant, spreading agent, water-proofing agent, bonding agent.
Wrapper 1 can be nonwoven fabrics or felt according to actual needs.
Referring to Fig. 3-Fig. 5, the goods of this compound acoustical panel, it is mainly used on the noise reduction process of compressor, and it comprises that coaming plate 3 and lid connect loam cake 4 above that.
Coaming plate 3 is determined through disposable, and is rectangular, and the length of present embodiment coaming plate 3 is less than the girth of loam cake 4, and the length that also can be designed to coaming plate 3 according to actual needs is equal to or greater than the girth of loam cake 4.Coaming plate 3 is rolled into cylindric sidewall compressor and wraps, and fixing through the VELCRO on it 3.1, and loam cake 4 covers at the top of coaming plate 3, wraps the top of compressor simultaneously.
Through the goods of the above-mentioned compound acoustical panel of parcel on compressor, the noise that can make compressor is reduced to 50 decibels from 80 decibels, and its fire prevention simultaneously, water resistance are superior, and the quality of item of this compound acoustical panel is light, helps the lightweight of air conditioner.
