PROCESS FOR PROCESSING ELASTOMER COMPOSITIONS |
摘要 |
A process is provided for producing elastomeric compositions by forming a mixture of polymeric material, a reinforcing agent, a processing aid and a vulcanizing agent. The process of the invention is continuous and includes the repeated, sequential steps of admixing the polymeric material along a first mixing zone defined by a space wherein the gross energy applied induces a first operating temperature range. The mixture of the first zone is continuously passed into and through a second mixing zone while adding and admixing the reinforcement agent and processing aid therewith, the second mixing zone being defined by a space wherein the gross energy applied induces a second operating temperature range. The mixture of the second zone is then continuously passed into and through a third mixing zone while adding and admixing the vulcanizing agent therewith, the third mixing zone being defined by a space wherein the gross energy applied induces a third operating temperature range. The mixture of said third zone is the continuously passed into and through a delivery zone to extrude the mixture in the form of the elastomeric composition, with the second and third operating temperature ranges being lower than the first operating temperature range. |
