Abstract
The invention relates to a binding material, in particular to an automobile sound deadening film which is used on metal plates for locally reinforcing the metal plates and particularly on automobile doors to reduce noises generated by the vibration of a running automobile. The automobile sound deadening film is prepared by mixing and extruding 10-25 percent of synthetic rubber, 5-15 percent of thermoplastic resin, 5-20 percent of thickening resin, 10-25 percent of plasticizing agent, 25-50 percent of vibration damping and sound deadening agent, 10-20 percent of oil absorbing and filling agent and 5-10 percent of reinforcing filling material. The automobile sound deadening film can be used for the large-area sound deadening and vibration damping of the metal plates during the automobile manufacturing process. When being used, the automobile sound deadening film can be operated by hands, is innoxious and odorless, is easy to separate from release paper, has good manufacturability, can not shift after being pasted, is less susceptible to oil washing, phosphating process, electrophoresis, paint spraying and drying, and other subsequent automobile body manufacturing processes and is convenient to use.
