Abstract
The utility model discloses a carriage wallboard for noise reduction. The carriage wallboard for noise reduction comprises a car wall frame. A noise reduction material layer is filled in the car wall frame. The carriage wallboard for noise reduction is characterized in that a shock-proofing noise absorption plate covers an outside surface of the noise reduction material layer. An outer covering covers an outside surface of the shock-proofing noise absorption plate. A soft internal decoration material layer covers an inside surface of the noise reduction material layer. An inner covering sticks to an outside surface of the soft internal decoration material layer through a structure adhesive layer. Due to the fact the technical scheme is adopted, the carriage wallboard for noise reduction has the advantages that the operation is simple, the overflow of the inner noise reduction material can be avoided, the soft decoration material can be connected with a multi-holes plate to a whole through an adhesion mode, and therefore the attractive degree of appearance of the noise reduction plate is improved.
Description
Technical field
The utility model technology relates to compartment wallboard preparing technical field, particularly a kind of noise reduction compartment wallboard.
Background technology
The vehicular oil engine noise is large, and for satisfying the noise reduction requirement, the car wall must be taked noise reduction technology.The composition of noise reduction compartment wallboard is the inside panel from the framework that outside to inside is followed successively by exterior skin, filling acoustic damping materials, the soft ornament materials of stickup.Inside panel is generally expanded metal, and the effect of soft ornament materials is to prevent that acoustic damping materials from exposing, and plays isolation and decoration function.
At present general employing is coated with the method for instant drying adhesive or brushing all purpose adhesive etc. at the soft ornament materials such as inside face sticking glass silk cloth of expanded metal.It is that inner decoration material is failed and the breaker plate integral adhesive that employing is coated with the problem that instant drying adhesive exists, and unfairness after pasting visually has dark district, and appearance poor is along with coming off appears in the prolongation ornament materials of period of service; Adopt the method for brushing glue glue then to occur and leak outside, pollute noise reduction plate outside face.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of for the deficiencies in the prior art and defective can effectively prevent the excessive of inner acoustic damping materials and make soft ornament materials and the noise reduction compartment wallboard of breaker plate integral adhesive.
The technical matters that the utility model solves can realize by the following technical solutions:
A kind of noise reduction compartment wallboard, comprise car wall framework, in described car wall framework, be filled with the acoustic damping materials layer, it is characterized in that, outside face at described acoustic damping materials layer is coated with one deck damping abatvoix, is coated with one deck exterior skin at the outside face of described damping abatvoix; Inside face at described acoustic damping materials layer is coated with the soft interior trim material bed of material of one deck, is pasted with inside panel by the sqtructural adhesive layer on the outside face of the described soft interior trim material bed of material.
Preferably, described acoustic damping materials layer is the glass wool layer.
Preferably, the described soft interior trim material bed of material is the fibrous glass layer of cloth.
Preferably, described inside panel is expanded metal.
Owing to adopted above-mentioned technical scheme, the utility model is simple to operate, effectively prevents the excessive of inner acoustic damping materials and makes soft ornament materials and the breaker plate integral adhesive, has improved the good looking appearance degree of noise reducing plate.
Description of drawings
Fig. 1 is the structural representation of a kind of Novel noise reduction plate for vehicular oil engine of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment of the utility model, further set forth the utility model.
Referring to shown in Figure 1, a kind of noise reduction compartment wallboard that provides among the figure comprises car wall framework 5, is filled with acoustic damping materials layer 3 in car wall framework 5, outside face at acoustic damping materials layer 3 is coated with one deck damping abatvoix 4, is coated with one deck exterior skin 6 at the outside face of damping abatvoix 4; Inside face at acoustic damping materials layer 3 is coated with the soft interior trim material bed of material 2 of one deck, is pasted with inside panel 1 by sqtructural adhesive layer 7 on the outside face of the soft interior trim material bed of material 2.Acoustic damping materials layer 3 is the glass wool layer.The soft interior trim material bed of material 2 is the fibrous glass layer of cloth.Inside panel 1 is expanded metal.
The expanded metal of this noise reduction compartment wallboard and glass wool cloth no longer adopt traditional adhering method that is coated with instant drying adhesive or brushing all purpose adhesive, but adopt sqtructural adhesive to carry out bonding, adopt suitable diluent dilution glue, diluent can be selected the diluent of paint of the same type, can select the diluent of epoxy primer, PU structural adhesive can select the diluent of polyurethanes lacquer such as epoxy structural rubber; Gelatin viscosity is can adopt common spraying equipment spraying to be advisable, general 18～30s(is coated with-4 glasss), after being diluted to appropriate viscosity, glue puts into spray painting equipment, expanded metal in order to the bonding one side glue spraying of glass wool cloth after, sticking glass silk cloth, simple to operate, spraying method is identical with the spray paint mode, can effectively prevent the excessive of inner glass cotton and make glass wool cloth and the expanded metal integral adhesive, improve the good looking appearance degree of noise reducing plate.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
