Abstract
The utility model relates to an engine compartment gives sound insulation, engine compartment gives sound insulation, including the puigging, the intermediate level of puigging is soundproof cotton, soundproof cotton to be the PP -PET fibre composite cotton, the PP -PET fibre composite is cotton has fine absorbing effect, density is low, its density only be centrifugal glass cotton's 14, and install and the use can not produce superfine fiber, avoids causing injury, environmental protection safety to constructor. The problem of among the prior art engine compartment's puigging weight heavy, detrimental to health is solved.
Description
Technical field
The utility model relates to machinery space field, particularly a kind of sound insulation machinery space.
Background technology
Driving engine is the main source of coach noise, and machinery space operating temperature is higher.Therefore the acoustical cotton of machinery space assembling should possess good sound-absorbing, fire-retardant and heat resistance.
Existing engine cabin of passenger car sound absorption materials is mostly three-layer composite structure, three-layer composite structure is respectively gum, rotary glass silk flosssilk wadding and perforated aluminum foil, wherein rotary glass silk flosssilk wadding is the filamentary material be made up of the glassification fiber of melting, sound-absorbing effect is better, good flame resistance simultaneously, but this density of material is higher, its density is about 60kg/m
3, be unfavorable for the lightweight of machinery space; On the other hand, rotary glass silk flosssilk wadding needs to cut in installation process, then nailing is fixed, fibrous glass in cutting process in rotary glass silk flosssilk wadding is very easily broken, broken rotary glass silk flosssilk wadding is in atmosphere floating, thus with the direct skin contact of operating personal, contactee there will be that skin is itched, irritated symptom, even can be carcinogenic, be detrimental to health.
Utility model content
The purpose of this utility model is to provide a kind of sound insulation machinery space, with the sound isolating layer Heavy Weight solving machinery space in prior art, the problem that is detrimental to health.
The technical solution of the utility model is: a kind of sound insulation machinery space, comprises sound isolating layer, and the interlayer of sound isolating layer is Sound-proof material, and described Sound-proof material is that PP-PET fiber composite is cotton.
The bottom of described sound isolating layer is gum, and sound isolating layer is adhesively fixed by gum and machinery space panel.
Described sound isolating layer is covered with the fixed network for fixing sound isolating layer, fixed network, sound isolating layer and machinery space panel are fixed by screw.
Described sound isolating layer is provided with the preformed hole with screw fit.
The beneficial effects of the utility model are: described sound insulation machinery space, comprise sound isolating layer, the interlayer of sound isolating layer is Sound-proof material, and described Sound-proof material is that PP-PET fiber composite is cotton, compared with traditional Sound-proof material, PP-PET fiber composite cotton has good sound-absorbing effect, density is low, and its density is only 1/4 of rotary glass silk flosssilk wadding, and installation and use procedure can not produce superfine fibre, avoid damaging workmen, Environmental Safety.
Further, described sound isolating layer is adhesively fixed on machinery space panel by the gum of bottom, top layer is covered with the fixed network for fixing sound isolating layer simultaneously, fixed network, sound isolating layer and machinery space panel are fixed by screw, by the fixed network of setting and driving engine on-deck screw being fixed, screw is fixed and is adhesively fixed to combine and sound isolating layer can be made more firm regularly.
Further, described Sound-proof material is provided with preformed hole, makes sound isolating layer convenient fixing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of sound isolating layer of sound insulation machinery space;
Fig. 2 is the elevational schematic view that a kind of sound isolating layer of sound insulation machinery space is fixed on machinery space;
Fig. 3 is the schematic top plan view that a kind of sound isolating layer of sound insulation machinery space is fixed on machinery space.
Detailed description of the invention
The detailed description of the invention of a kind of sound insulation machinery space of the present utility model: as shown in Figure 1 to Figure 3, a kind of sound insulation machinery space, the surface layer of its sound isolating layer 1 is perforated aluminum foil 11, and bottom is gum 13, interlayer is Sound-proof material 12, Sound-proof material 12 is that PP-PET fiber composite is cotton, and this Sound-proof material 12 has good sound-absorbing effect, and density is low, its density is only 1/4 of rotary glass silk flosssilk wadding, and installation and use procedure can not produce superfine fibre, avoid damaging workmen, Environmental Safety.
Before installing, edge sealing process is carried out to sound isolating layer 1, and stamp out preformed hole 14 and prepare against nailing and fix.During installation, as shown in Figure 2 and Figure 3, first sound isolating layer 1 back-adhesive surface is pasted onto nacelle panel face 3, then the wire netting 2 of fixing sound isolating layer 1 is covered to note on sound isolating layer 1, finally pass wire netting 2, sound isolating layer punching press preformed hole 14 successively with thread-forming screw, tighten thread-forming screw wire netting 2, sound isolating layer 1 are fixed, wire netting 2, sound isolating layer 1 are fixed by screw with machinery space panel 3, by being fixed with machinery space panel 3 screw by the wire netting 2 of setting, screw is fixed and is adhesively fixed to combine and sound isolating layer can be made more firm regularly.
In addition, in other embodiments of the present utility model, the wire netting described in above-described embodiment can also be aluminum alloy net, and described thread-forming screw can also be the screw of the other types such as holding screw.
