The invention discloses a production technology of
ethylene propylene rubber and relates to the field of rubbers. The production technology of the
ethylene propylene rubber comprises five technological processes, namely
polymerization, removal of a catalyst, recycling of a
monomer and a
solvent, coagulation as well as
dehydration and
drying. According to the production technology of the
ethylene propylene rubber, a catalyst (described in the specification) is adopted in the
polymerization process, a
reaction speed is greatly increased, a full
liquid phase thermal insulation reaction is adopted in the
polymerization process, namely reaction heat is used for warming a polymerization kettle in a
thermal insulation manner,
optimal design of the polymerization kettle can meet reactant mixing requirement, a liquid-liquid filling
reaction system can accurately
control parameters of the polymerization technological process and product quality, concentration of a
polymer glue solution is high, quantity of a cycle
solvent is low, efficiency of recycled steam and recycling rate of the
solvent are high, the polymerization kettle is small in volume but high in production intensity, conversion per pass is high, raw materials and a cycle
monomer do not need to be refined, content of residual catalyst in the product is low, qualified rate of a product is high, consumption of the raw materials and the catalyst is low, and content of a
vanadium catalyst in
sewage is low. The production technology of the
ethylene propylene rubber is good, high in production elasticity and low in investment.
