Abstract

The present invention provides a reclaimed rubber activator sulfo synthetic method, and relates to reclaimed rubber additive production technical field, the reclaimed rubber activator sulfo synthetic method comprises the following steps: antioxidant mother liquor is melted, the melted antioxidant mother liquor is pumped into a reactor, each reactor is fed with 2.8 tons of the material; the antioxidant mother liquor is heated to 120 DEG C, and stirred and dewatered for 40 minutes, and the temperature is dropped to 80 DEG C; under stirring conditions, a certain quantity of sulfur monochloride is dropwise added, the temperature gradually rises to 140 to 145 DEG C for high temperature synthesis; after the material is fed, the material is stirred for 30 minutes, the reactor is heated to 120 DEG C, after 2 hours of thermal insulation, the reactor is heated to 140 DEG C, after 2 hours of thermal insulation, the material in the reactor is transferred into a finished product packaging kettle, and stirred and cooled to 85 DEG C, and the material is packed to obtain a finished product. The reclaimed rubber activator sulfo synthetic method has the advantages of simple process and easy control of the process conditions, and the synthesized reclaimed rubber activator has the characteristics of no smell, less dosage and good effect, and compared with the activator synthesized by a conventional method, the dosage can be reduced by more than 50%.

Description

technical field [0001] The invention relates to the technical field of production of regenerated rubber auxiliary agents, in particular to a method for thiosynthesizing a regenerated rubber activator. Background technique [0002] Regenerated rubber refers to waste rubber that undergoes physical and chemical processes such as crushing, heating, and mechanical treatment to make its elastic state into plastic and viscous rubber that can be re-vulcanized. Reclaimed rubber is a rubber that is processed from vulcanized scraps in the production of rubber products, has a certain degree of plasticity, and can be reused. According to the different waste rubber used, reclaimed rubber is divided into outer tires, inner tubes, rubber shoes and so on. Reclaimed rubber can partially replace raw rubber for rubber products, saving raw rubber and carbon black is also beneficial to improve processing performance and certain properties of rubber products. The regeneration process is a proces...
