The rubber composition has three characters of the low temperature resistance, grease resistance and high temperature resistance on the basis of the good characters of the pure nitrile rubber, the production process is simple, and the cost is low.

The invention provides a method for preparing a chlorinated butyl rubber damping material, comprising the following steps of: mixing chlorinated butyl rubber, C5 / C9 copolymerized petroleum resin, padding, zinc oxide, 2,2-dithio benzothiazole and tetramethyl thiuram disulfide to obtain a sizing material, wherein the mass ratio of the chlorinated butyl rubber to the C5 / C9 copolymerized petroleum resin is (75-85):(15-25); and carrying out vulcanization on the sizing material to obtain the chlorinated butyl rubber damping material. In the invention, when the mass ratio of the chlorinated butyl rubber to the C5 / C9 copolymerized petroleum resin is (75-85):(15-25), the temperature of the effective damping functional area of the obtained damping material is -40 DEG C to 40 DEG C; the temperature area is wider and covers higher temperature and lower temperature; therefore, the obtained damping material can be applied to the device or the equipment with a working temperature of -40 DEG C to 40 DEG C and has wider application range. Furthermore, the preparation method provided by the invention is simple in processing and easy for realizing the industrial production.
