Learn Synthetic Rubber Production Technology
Synthetic rubber production process can be divided into the synthesis and purification of monomers, polymerization process and post-processing of three parts rubber
Production and refining monomer
The basic raw material of synthetic rubber monomer, commonly used purification methods are distillation, washing, drying and the like.
Monomer polymerization initiator and in the course of a polymerization catalyst under reaction of the polymer. Sometimes using a polymerization apparatus, sometimes more than one series. Synthetic rubber polymerization process mainly two kinds of emulsion polymerization applications and solution. Nowadays, the use of emulsion styrene-butadiene rubber, isoprene rubber, butyl-propylene rubber, butyl rubber.
After the deal is material (latex or glue) after the polymerization reaction, by removing unreacted monomers, cohesion, dewatering, drying and packaging steps, the final process to obtain the finished rubber. Emulsion aggregation process mainly add electrolyte or polymer flocculant, so that damage to the emulsion particles precipitated. Solution polymerization agglomeration process with hot water condensate based. Coagulation, and the precipitated particles, containing a lot of water, to be dewatered, and dried.
