Abstract

A single screw extrusion desulfurization and post-processing system, and a method for preparing reclaimed rubber, the single screw extrusion desulfurization and post-processing system comprising: a single screw desulfurization device, a single screw post-processing device and a closed connection device connecting the single screw desulfurization device and the single screw post-processing device. The single screw post-processing device comprises a post-processing feeding device and the post-processing device mutually connected, and the post-processing screw running through the post-processing feeding device and the post-processing device.

Description

technical field [0001] The invention relates to a device and a process method for preparing reclaimed rubber by desulfurization of waste rubber and post-treatment; specifically, the invention relates to a single-screw extrusion desulfurization and post-treatment system and a method for preparing reclaimed rubber. Background technique [0002] The waste rubber desulfurization process is to change the waste rubber from an elastic state into a plastic and viscous rubber that can be re-vulcanized through physical and chemical processes such as crushing, heating, and mechanical treatment. bond, S-C bond without destroying the C-C bond as much as possible, selectively destroying the three-dimensional cross-linked network structure, avoiding breaking the C-C main chain as much as possible, and reducing the vulcanized rubber to an unvulcanized state. [0003] At present, there are mainly two methods for desulfurization of waste rubber at home and abroad: the first method is to use d...
