Abstract

The present invention discloses a rubber composition, a processing method for obtaining the rubber composition, and application of the composition in processing of flame-retardant products. The rubber composition includes a rubber matrix and essential components. The rubber matrix includes a branched polyethylene with a content represented as A, in which 0<A≤100, and an EPM and an EPDM with a total content represented as B, in which 0≤B<100. The essential components include 1.5 to 10 parts of a crosslinking agent and 40 to 300 parts of a flame-retardant agent. The rubber composition can be applied to production of flame-retardant products, such as flame-retardant cable, flame-retardant cool air hose for automobile, flame-retardant sealing strip, high-temperature-resistant flame-retardant conveyor belt, and flame-retardant waterproof coil. The products have good flame-retardant effects and mechanical properties.
