Technical Field
[0001] The present invention relates to the technical field of rubber preparation, and in particular to a production device and a production process for graphene-doped high-strength nitrile rubber. Background Art
[0002] The biggest feature of nitrile rubber NBR is its excellent oil resistance. However, due to the double bonds in the main chain of NBR, its heat aging resistance, weather resistance and chemical stability are poor. The main chain of chloroether rubber ECO is composed of ether bonds and carbon-carbon single bonds, and the side chain contains chlorine atoms. It has good heat aging resistance, ozone resistance, excellent oil resistance, low temperature resistance and adhesion properties.
[0003] In the prior art, by adding graphene to NBR rubber, the ozone aging resistance, heat aging resistance, low-temperature resistance and adhesion performance of NBR rubber can be improved, thereby greatly broadening the application range of NBR rubber. During the preparation of NBR rubber, a regulator needs to be intermittently added to the polymerization kettle to assist production. However, when adding the regulator, workers generally need to manually control it, resulting in a large workload for the workers and affecting processing efficiency. Summary of the Invention

The rotating disk (609) is provided with a cam groove (611) that cooperates with the protrusion (610), so that the connecting plate (604) drives the fixed plate (606) and the slide (605) to move along the slide rail (608), thereby controlling the sealing plug (607) to open the slot (502) at a certain frequency, and intermittently adding the regulator into the polymerization kettle (1) to assist the reaction of butadiene and acrylonitrile; S4: Finally, the materials that have completed the reaction in the polymerization reactor (1) enter the next process through the output pipe (10).
