Abstract

The invention discloses a preparation method for a damping rubber of automatic instruments. The preparation method specifically comprises the following operation steps: S1) preparing raw materials; S2) plasticizing: putting raw rubber, chemigum and cis-polybutadiene into a plasticator, adopting a thermal plasticizing method for plasticizing for 10-20 minutes under the temperature at 30-50 DEG C, and then ending plasticizing; S3) mixing; S4) discharging after the ending of mixing under a mixing temperature at 160 DEG C, and standing by for 15 hours under room temperature, thereby acquiring a mixed rubber; S5) molding. According to the invention, due to the compatibility and co-vulcanization between substrates, high tensile strength, high bonding strength, excellent damping property and excellent reinforcing property of the product can be guaranteed; the product has excellent tear resistance, tensile strength, toughness, damping effect, wearing resistance and ageing resistance; a layer of epoxy zinc-rich paint is coated on the product surface, so that the oxidation resistance of product is greatly enhanced and the product is difficult to deform and is durable.
