STUDIES AND APPLICATION OF RECLAIMED BUTYL RUBBER BY RADIATION

The waste vulcanized butyl rubber is degraded by radiation and butyl rubber is reclaimed. In this paper, absorbed dose, dose rate, and pretreatment methods on properties of reclaimed butyl rubber are studied. The reclaimed butyl rubber is easily processed. It has excellent mechanical properties: the elongation is more than 40％ the plasticity is more than 0.25, the tensile strength is more than 10MPa. The service life of products made of reclaimed butyl rubber by radiation is as long as products made of routine materials. It is a good method for reclaimed plants to provide the reclaimed butyl rubber by rediation.
