Lilliput car floor beat insulating sound insulating board
Technical field
The utility model relates to the cover panel on the automotive floor panel panel beating, specifically lilliput car floor beat insulating sound insulating board.
Background technology
Along with automobile is more and more universal, people are also increasingly high to the traveling comfort requirement of automobile, reduce car noise and also paid close attention to by people widely by the heat that freeing pipe distributes with obstruct.
But domestic automobile does not have the heat-insulating equipment of the outside noise reduction in floor basically, is the fine plates of single layer fiber crops even have yet.Because numb fine plate moisture resistance is poor, run into rainwater and be prone to the tide damage, do not have the sound-insulating and heat-insulating effect, also be unfavorable for environmental protection.
Goal of the invention
The purpose of the utility model is a kind of novel floor beat insulating sound insulating board of design, makes it have good heat insulation noise reduction and compliance with environmental protection requirements.
Summary of the invention
The utility model is to realize design goal like this.
On the panel beating of automobile external floor, be coated with heat-insulating sound-insulating plate body 1; Be processed with a plurality of mounting holes 2 on the heat-insulating sound-insulating plate body 1; Have on the heat-insulating sound-insulating plate body 1 and interlayer 4 disposable fopam gluings initial bed 3 together; Be coated with the interlayer 4 that is bonded together with precoat 5 disposable pressings on the initial bed 3; Be coated with on the interlayer 4 and interlayer 4 and initial bed 3 disposable composite adhered precoats 5 together.
The various material sound insulating and absorbings of the utility model, heat-insulating flame-retardant are functional, and compliance with environmental protection requirements can built the riding environment of safety and comfort for the client.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
On the panel beating of automobile external floor, be coated with heat-insulating sound-insulating plate body 1; Be processed with a plurality of mounting holes 2 on the heat-insulating sound-insulating plate body 1; Have on the heat-insulating sound-insulating plate body 1 with XPE (processes for chemically crosslinked polyethylene) and process, heat is had isolated and noise is had stronger absorptive character, with interlayer 4 disposable fopam gluings initial bed 3 together; Be coated with on the initial bed 3 with the fine plate of fiber crops and process, have high strength, deep drawn property, stronger constancy, flame resistance and heat-insulating sound-insulating, the interlayer 4 that is bonded together with precoat 5 disposable pressings; Be coated with on the interlayer 4 with aluminium foil paper and process, it is good to have heat insulation a, sound insulation, protection against the tide, shading, typing, with interlayer 4 and initial bed 3 disposable composite adhered precoats 5 together.
When making heat-insulating sound-insulating plate body 1, pass through foaming to initial bed 3 earlier, be bonded on the interlayer 4, pass through mould HTHP disposable thermal synthesis type to the interlayer that is bonded with initial bed 34 with precoat 5 again, be incubated a period of time again.Like this, the utility model is had good stability, can not produce the distortion bounce-back.On the heat-insulating sound-insulating plate body of making 1, process and outer corresponding 10 mounting holes 2 of floor panel beating of automobile; Be fixed on heat-insulating sound-insulating plate body 1 on the outer underfloor panel beating of automobile through mounting hole 2 with bolt, get final product.
The utility model not only has good heat-proof quality, noise reduction sound insulation value, and toughness, impact resistance, anti tear and protection against the tide, flame retardance are superior, are on-deformable good environment-friendly products.
