Abstract
The utility model relates to a reinforcing and damping plate for an automobile. The reinforcing and damping plate for the automobile comprises a butyl rubber layer and a rubber modified epoxy resin layer which is connected to the butyl rubber layer. The utility model provides the reinforcing and damping plate for the automobile, which has high hardness, high intensity, low density and high damping performance and solves the problem that the conventional reinforcing and damping material for the automobile with high hardness, high intensity and low density has low damping performance and the problem that the reinforcing and damping material for the automobile with high damping performance has low intensity.
Description
Technical field
The utility model relates to automobile-used material, relates in particular to a kind of automobile and strengthens damping panel.
Background technology
For car, NVH(noise, vibration and traveling comfort) performance is one of major criterion of weighing its class and brand, becomes the important counterweight of the various brands vehicle market competitiveness.The NVH performance of car load can promote by ACTIVE CONTROL and Passive Control dual mode, aspect Passive Control, because the difficulty that body structure is changed is bigger, using the material with NVH effect (as sound-absorbing, sound insulation, vibration damping, sealing etc.), to carry out the vibration and noise reducing processing be simple relatively and necessary.From the vehicle vibration damping aspect, at present, the mode that Material Used carries out vibration damping mainly contains two kinds, promptly strengthens vibration damping and damping vibration attenuation, and strengthening vibration damping is to improve the natural frequency of vehicle body panel beating by material, thereby avoids resonance; And being vibrational energy by material dissipation panel beating, damping vibration attenuation reaches the vibration damping purpose.The most effects of automobile vibration reduction material at present are more single, and the damping capacity of reinforcement material is bad, and the booster action of damping material is relatively poor again.In China Patent No. is ZL200820141847.1, name is called and discloses a kind of automobile reinforcement noise reduction material in the patent documentation of " automobile reinforcement acoustic damping materials ", it comprises and isolates bottom, surface layer and fill in glue-line between bottom and surface layer, improve the intensity of automotive body sheet by the heat hardening of glue-line, play the effect of noise reduction simultaneously, also be the reinforcement damping modes.But this kind strengthened vibration-absorptive material, though hardness is good, intensity is high, the little damping effect of density is bad, the setting rate of epoxy resin is slow.
Summary of the invention
The utility model provides the automobile that a kind of hardness is good, intensity is high, density is little and damping performance is good to strengthen damping panel, it is bad to have solved the automobile reinforcement vibration-absorptive material damping performance that existing hardness is good, intensity is high, density is little, and the automobile that damping performance is good is strengthened the bad problem of vibration-absorptive material intensity.
Above technical matters solves by following technical solution, and a kind of automobile is strengthened damping panel, comprises butyl rubber layer and the rubber modified epoxy resin layer that is connected on the butyl rubber layer.The rubber modified epoxy resin layer mainly act as the rigidity that strengthens the vehicle body panel beating, rubber modified epoxy resin is after high-temperature baking solidifies, the material sclerosis, to steel plate reinforcement, increased steel plate rigidity, reduce the sensivity of steel plate to vibration, improve the natural resonant frequency of steel plate, make the numerical value of its natural frequency and the natural frequency scope of vehicle motor and other subsystems produce obvious difference, make it be difficult for producing resonance and sympathetic response, the butyl rubber layer mainly act as and suppresses the low-frequency vibration noise that vehicle body panel beating excited target produces.Because the numerical value higher (room temperature condition is more than 0.2) of the damping factor of butyl rubber material own, so its effectiveness in vibration suppression excellence, when the vehicle body steel plate vibrates, the macromolecular chain of rubber produces motion, thereby produce repeatedly repeated deformation (stretching, compression, shearing etc.) and make system change a part of elastic energy into irreversible heat energy dissipation, thereby reach the purpose of damping vibration attenuation.
As preferably, 1.5-3 millimeters of the thickness of described butyl rubber layer.
As preferably, the thickness of described rubber modified epoxy resin layer is 1-1.2 millimeters.
As preferably, be coated with superficial layer on the described rubber ring epoxy layer.
As preferably, described superficial layer is that glass is weaved cotton cloth.
As preferably, described butyl rubber layer is mutually bonding by butyl rubber with described rubber ring epoxy layer.Carry out bondingly with butyl rubber self, saved adhesive, dropped to cost.
The utlity model has following beneficial effect: integral material adopts the structure of enhancing-damping vibration attenuation, both passed through the humidification of rubber modified epoxy resin material, avoid the generation of resonance energy, the vibrational energy that utilizes the shock damping action consumption of butyl rubber material to produce again, two kinds of damping of vibrationss are brought into play jointly, promoted the damping of vibrations of material to greatest extent to the vehicle body panel beating, especially for the bigger vehicle of car door area, vibrational energy after its excited target is stronger, use the effectiveness in vibration suppression of this sheet material more more excellent than using homogenous material, and the curing rate of rubber modified epoxy resin is fast, reduces the energy consumption of solidifying baking.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a running condition scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Referring to Fig. 1, a kind of automobile is strengthened damping panel, comprise butyl rubber layer 1 and the rubber modified epoxy resin layer 2 that is connected on the butyl rubber layer, surface coverage at rubber modified epoxy resin layer 2 has superficial layer 3, superficial layer 3 is weaved cotton cloth for glass, the optimum thickness of butyl rubber layer 1 is 1.5-3 millimeters, in the present embodiment be 1.8 millimeters, the optimum thickness of rubber modified epoxy resin layer 2 is 1-1.2 millimeters, in the present embodiment be 1.1 millimeters, it is that adhesive bond by epoxy resin itself is on epoxy resin layer that glass is weaved cotton cloth, rubber modified epoxy resin layer 2 and butyl rubber layer 1 are to be undertaken bonded assembly by the viscosity of butyl rubber itself, in the production process of whole sheet material, epoxy material bonds with the butyl rubber layer after hardening through pre-high-temperature baking again.
Referring to Fig. 2, the right side of car body sheet metal component 4 is the side in car among the figure, and the left side is the side outside car, and during use, the butyl rubber layer 1 of this automobile being strengthened damping panel sticks on the side in car of car body sheet metal component 4.The existing used material that has only epoxy resin layer and superficial layer, in order to make epoxy resin can be bonded on the automobile metal plate work, elder generation is coated with uncured epoxy resin and installs on the car body sheet metal component, makes epoxy resin cure through overbaking then, so operation is many, consumes energy during baking, and this reinforcement damping panel, because the toughness of butyl rubber material own, pressure-sensitive adhesive is passed through in auto assembly operation and vehicle body panel beating in the back in order to be cured, do not need to be coated with other adhesive, need not to carry out application and baking yet.
