실험 절차

1,422 parts of stearic acid is added to 10,000 parts of ethanol, and mixed together at 75° C. 507 parts of zinc hydroxide is gradually added to the mixture, and is mixed for one hour after completion of the addition. The resultant mixture is cooled to 20° C., and the reaction product is filtered to remove reaction residue and ethanol. The obtained reaction solid product is dried at 150° C. for 3 hours using a heating vacuum drier. The dried product is taken out from the drier, and is allowed to stand for cooling, as a result of which a solid product of zinc stearate is obtained. After the obtained solid product is milled using a jet mill, the milled product is classified using an ELBOW-JET CLASSIFIER (available from Matsubo Corporation), whereby powdery zinc stearate particles 1 having a volume average particle diameter of 9.6 μm are obtained. The classification cut points when the particles are classified using Elbow-jet classifier are shown in Table 1. The particle size distribution (the ratio of particles having a particle diameter of 25 μm or more, and the ratio of particles having a particle diameter of 40 μm or more) of the obtained zinc stearate particles 1 is shown in Table 1.
