<p>Disclosed are a granular stearate, a preparation method thereof, and the use of the stearate in the field of rubber and plastics. The stearate has a particle size of 150-880 µm, a bulk density of 0.3-0.7 g/cm3 and a weight loss on heating of = 1.5%. The preparation method thereof comprises: emulsifying stearic acid under heating in an aqueous solution of a metal salt corresponding to the stearate, and subsequently adding an aqueous solution of sodium hydroxide therein. The stearate prepared is granular, free of dust, and environmentally friendly; when used as a rubber and plastic aid, it is not only conveniently added and measured, but also the production efficiency and the quality of rubber and plastic main products are significantly improved.</p> |
