Description
Technical Field
The utility model relates to a car is with thermal-insulated sound insulation pad belongs to auto-parts technical field.
Background
During the running process of the vehicle, a lot of noises including engine noise, wind noise, road noise and the like are generated around and in the vehicle, and the noise sources are spread into the vehicle from various channels to cause discomfort to people; secondly, when the automobile runs, the local temperature of the engine compartment can be too high, even reaching 160 ℃, and the too high temperature can affect the performance of automobile parts in the engine compartment and even cause the aging and spontaneous combustion phenomenon of the parts for a long time.
Therefore, it is thermal-insulated simultaneously again to set up the sound-proof pad in the vehicle at present and isolate the noise to this improves member's in the car comfort, thereby this sound-proof pad need possess good heat-proof quality simultaneously and protect automobile parts, increases spare part life.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art and providing a car that is used for adhering at engine compartment and oil tank shell backplate etc. and is protected the object and is insulated from sound and fill up with heat.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a heat and sound insulation pad for an automobile comprises a texture aluminum foil adhesive film layer, a mixed glass fiber needle-punched composite layer and an adhesive layer; the texture aluminum foil adhesive film layer comprises a surface aluminum foil and a composite temperature-resistant adhesive film, and the mixed glass fiber needling composite layer is two-side mixed polyester fiber of a glass fiber felt; the surface layer aluminum foil is hot-pressed on one side surface of the mixed glass fiber needling composite layer through the composite temperature-resistant adhesive film, and the adhesive layer is compounded on the other side surface of the mixed glass fiber needling composite layer.
Preferably, the surface of the textured aluminum foil adhesive film layer is provided with dot array textures, the dot array textures are in a concave-convex interval mode, the dot diameter of the dot array textures is 4-6mm, and the interval is 5-10 mm.
Preferably, the surface of the texture aluminum foil adhesive film layer is provided with diamond grid textures, the side length of each diamond grid is 5-15mm, and the angle of each diamond is 15-45 degrees.
Preferably, the thickness of the surface layer aluminum foil of the texture aluminum foil adhesive film layer is 0.1-0.5 mm.
Preferably, the thickness of the mixed glass fiber needling composite layer is 3-5mm, and the mixed polyester fibers on two surfaces of the glass fiber felt are reinforced through needling.
Preferably, the mixed polyester fiber of the mixed glass fiber needle-punched composite layer is polyester PET fiber mixed with binder fiber.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the heat and sound insulation pad for the automobile adopts the aluminum foil composite glass fiber to be cut and molded; the mixed glass fiber needling composite layer is reinforced in a needling manner, so that the mixed glass fiber needling composite layer has a better entanglement structure and softness, and is easier to be adhered to a protected object through bending and extrusion; the aluminum foil has a good heat insulation function, the glass fibers have sound insulation and heat resistance, and the service life of automobile parts is prolonged to a certain extent.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a layer structure schematic diagram of a thermal and sound insulation pad for an automobile.
FIG. 2 is a schematic view of the needling reinforcing method of the mixed glass fiber needling composite layer.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
