The following disclosure provides many different embodiments, or examples, for implementing different aspects of the utility model.
Referring to fig. 1 to 2, the automobile lightweight damping adhesive comprises a damping layer 10, an adhesive layer 20 and a mesh layer 30, wherein the damping layer 10 has a porous structure 11; the adhesive layer 20 is arranged on the first surface of the damping layer 10; the mesh layer 30 is disposed on the second side of the damping layer 10, and the mesh of the mesh layer 30 is partially or completely embedded in the damping layer 10. Specifically, the meshes of the mesh layer 30 are partially or completely embedded in the second surface of the damping layer 10 along the thickness direction of the mesh layer 30. The mesh layer 30 is used to improve the tensile strength of the second surface of the damping rubber and prevent the damping layer 10 from cracking.
Automobile lightweight damping glue can paste the inboard at car panel beating 50 through pasting layer 20, and damping layer 10 is used for changing the holistic natural frequency of panel beating to reduce the vibrations of car panel beating 50, the noise reduction is equipped with porous structure 11 in the damping layer 10, through the 11 partial noises that absorb of porous structure, thereby improve syllable-dividing effect, noise in the reduction car improves riding comfort. In addition, the porous structure 11 can effectively reduce the weight of the damping layer 10, and particularly, compared with the damping glue on the existing market, the damping glue is light in weight by 30-50%. The porous structure 11 also facilitates the signal to pass through the damping glue, and facilitates the signal transmission.
In one embodiment of the present invention, the damping layer 10 is a butyl composite. The butyl damping effect is good, harmful gas can not be volatilized, and the safety of personnel in the vehicle is guaranteed. The adhesive layer 20 is an environment-friendly adhesive layer compounded by butyl rubber, has strong adhesive adhesion, can be adhered to the automobile sheet metal 50 for a long time without deformation, and has stable performance within the temperature range of-35 to 180 DEG C
In one embodiment of the present invention, the porous structure 11 is disposed inside or/and on the surface of the damping layer 10. I.e. the porous structure 11 can be arranged inside the damping layer 10 at least at one of the first side and the second side. The porous structure 11 is formed by a foaming agent or formed in the damping layer 10 by a molding tool, and the weight of the damping rubber is reduced without affecting the sound insulation performance of the damping rubber.
In one embodiment of the utility model, the inner surface of the adhesive layer 20 is provided with an adhesive backed sticker 40. The adhesive backing 40 protects the adhesive layer 20 before use, and prevents the adhesive layer 20 from being damaged or air-dried to cause a decrease in adhesiveness. When the adhesive sticker 40 is installed, the adhesive sticker is removed and the adhesive sticker is attached.
In one embodiment of the present invention, the mesh layer 30 is a non-woven fabric or a glass fiber fabric. The non-woven fabric and the glass fiber fabric are used for improving the tensile strength of the second surface of the damping glue and preventing the damping layer 10 from cracking. Specifically, the non-woven fabric has good extensibility, and the glass fiber cloth has good strength. The non-woven fabric or the glass fiber fabric can be selected according to different requirements.
In one embodiment of the utility model, the damping glue has an overall thickness greater than 2 mm. According to long-term research, when the thickness of the damping rubber is less than 2 millimeters, the sound insulation effect is poor, and the damping rubber is not suitable for automobile sound insulation.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the claims and their equivalents.
