Abstract
The utility model discloses a reinforcing and denoising material for a car, and aims at providing a reinforcing and denoising material for a car which has the same hardness with a steel plate of the car, and can reduce the weight of the car body, improve the rigidness and reduce the vibration, which comprises a surface layer and a bottom isolation layer, wherein a glue layer is arranged between the surface layer and the bottom isolation layer, and the surface layer is of one of a stainless steel foil plate, an aluminum foil plate, a glass fabric, a synthesized resin sheet, a synthesized rubber sheet, a leather, a cloth and a glass wood cloth. The glue layer is made of thermocuring epoxy resin glue. The reinforcing and denoising material has the same harness with that of the steel plate of the car, and has good initial viscous force and permanent bonding force with the steel plate, thereby playing a better reinforcing effect on the steel plate of the car. The material has light weight at a unit area and high strength; and being combined with the steel plate of the car, the material can prevent the deformation and rustiness of the steel plate, reduce the weight of the car body, improve the rigidness and reduce the vibration, so that the safety of the vehicle can be ensured while satisfying the requirements of light weight, comfort and low energy consumption of the car.
Description
Technical field
The utility model relates to a kind of automobile reinforcement acoustic damping materials.
Background technology
In recent years, auto-industry have the trend of attenuate motor-car body sheet greatly for pursuing the characteristics of lightweight, comfortable, low energy consumption.At present, the steel plate at most of position of vehicle is the sheet iron formation of 0.7-1.6mm by thickness, the phenomenon that steel plate thickness also brings car body component rigidity step-down, poor durability and noise to increase when reducing, the sheet steel located such as car door particularly, be difficult to satisfy the requirement of side collision, brought great threat for driver's safety.Because the reduction of steel plate thickness, make car door, backplate, vehicle body, engine bonnet and luggage-boot lid, add the positions such as gusset, ceiling of long vehicle, bending phenomenon occurs easily when being subjected to exterior impact, and sound also can directly pass to vehicle inside.
The utility model content
The utility model is in order to overcome weak point of the prior art, provide a kind of and have equal hardness with autobody sheet, weight per unit area is light, intensity is high, combine with autobody sheet, can prevent steel plate deformed, get rusty, reduce car body weight, the automobile reinforcement acoustic damping materials that improve rigidity, reduce to vibrate.
The utility model is achieved through the following technical solutions:
A kind of automobile reinforcement acoustic damping materials, it is characterized in that, comprise surface layer, bottom isolation layer, be provided with glue-line between surface layer and bottom isolation layer, described surface layer is any one in stainless steel foil plate, aluminium foil plate, glass woven fabric, synthetic resin sheet, neoprene sheet, skin, cloth, the glass wool cloth.
Described glue-line is a thermosetting epoxy resin glue.
Wherein bondline thickness is in 0.8～3.0mm scope, and the thickness of surface layer is in 0.1～1.0mm scope.
Be provided with a plurality of deflation holes in described surface layer and the glue-line.The density of described deflation hole is 8000～16000 holes of every square meter, and described deflation hole is the circular hole of diameter in 0.5～1mm scope.
The utlity model has following technique effect:
1. reinforcement acoustic damping materials of the present utility model have the hardness equal with autobody sheet, and are good with steel plate initial bonding strength and permanent adhesive power, so can play good strengthening action to autobody sheet.And weight per unit area is light, intensity is high.Combine with autobody sheet, can prevent steel plate deformed, get rusty, can reduce car body weight, improve rigidity, reduce vibration, thereby, make automobile when satisfying lightweight, comfortable, low energy consumption requirement, safety and bulk strength that can support vehicles.
2. reinforcement acoustic damping materials of the present utility model can be designed to the goods of difformity and specification according to the requirement of automobile different parts desired stiffness, have avoided the influence of stress concentration to automobile appearance.
3. reinforcement acoustic damping materials of the present utility model can also be changed vehicle structure design-calculated defective, paste reinforcement acoustic damping materials of the present utility model at the relatively poor position of rigidity, can avoid designing the trouble of later stage change.And, also can reduce the quantity that body support welds, improve productive temp.
Description of drawings
Fig. 1 is the cutaway view of the utility model automobile with the reinforcement acoustic damping materials.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the cutaway view of the utility model automobile with the reinforcement acoustic damping materials, comprise surface layer 1, bottom isolation layer 3, between surface layer and bottom isolation layer, be provided with glue-line 2, wherein, surface layer is any one in stainless steel foil plate, aluminium foil plate, glass woven fabric, synthetic resin sheet, neoprene sheet, skin, cloth, the glass wool cloth.The thickness of surface layer is in 0.1～1.0mm scope.Described glue-line is a thermosetting epoxy resin glue, and bondline thickness is in 0.8～3.0mm scope, and the bottom isolation layer adopts barrier paper.
If the product area is bigger, in surface layer and glue-line, be provided with a plurality of deflation holes 4.Deflation hole sees through surface layer and glue-line, or about 0.5mm does not see through below glue-line.
The density of described deflation hole is 8000～16000 holes of every square meter, and described deflation hole is the circular hole of diameter in 0.5～1mm scope.If product width is no more than 100mm, also can be when length is no more than 200mm without deflation hole.
During forming work, ready thermosetting epoxy resin glue is extruded by the numerical control extruder, isolation layer, surface layer are attached to respectively on the two sides of the glue-line that extruder extrudes by roll-in.Through the cutting machine cutting, in the punching of the surface of product, last roll-forming, packing are finished whole production process, obtain automobile of the present utility model reinforcement acoustic damping materials through tapping and plugging machine again.
During use, paste at car body welding shop or painting workshop, with moment take the barrier paper that is attached on the product with sudden force off, product is sticked on the position that needs stickup, firmly push and get final product.In paint shop along with the electrophoresis baking finish line, or paint drying line, slowly hardening, and bond together securely with vehicle body.
Although relate to a kind of automobile and carried out special description disclosed with the reinforcement acoustic damping materials with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
