The invention discloses a production method of a rubber
vulcanization accelerator DM, belonging to the technical field of production of rubber accelerators. The production method disclosed by the invention sequentially comprises the following steps of: a, adding 5000 L of water, 500 kg of a rubber accelerator M and 2-6 kg of a surface
active agent OP-10 into a
mixing tank in sequence; b, increasing the temperature to 40-55 DEG C while stirring for 1 h; c, pumping materials into an oxidization kettle through a
slurry pump, simultaneously, adding 4-10 kg of
sodium acetate, beginning to oxidize while the temperature in the oxidization kettle is increased to 60 DEG C, and controlling oxidization temperature at 60-80 DEG C; d, dropping
hydrogen peroxide solution with the
mass fraction of 7-12%, wherein the dropping speed is 100-200 L per hour, and the reaction time is 3-4 h; and e, determining reaction endpoint by using 1%
cobalt oleate, if the reaction materials are not changed in colour, determining that reaction is finished, after reacting, washing by using water, whirling,
drying and packaging. The production method disclosed by the invention has the advantages that little materials, the surface
active agent and
sodium acetate are contained in reaction water, so that the reaction water can be used repetitively; the purposes of protecting the environment and reducing consumption are achieved; the product quality achieves national primary standards; and the product yield is above 99.5%.
