Abstract

PURPOSE: To obtain a dehydrating agent for rubbers or plastics, which has excellent dispersibility and weathering resistance, by a method wherein ground whiting is hard-burnt to produce qhick lime, a metal salt of stearic acid is blended with quick lime, and the mixt. is pulverized and then mixed with naphthenic oil.
CONSTITUTION: Ground whiting such as limestone is hard-burnt at 1,300°C or higher to decarbonate it and to produce hard quick lime. The quick lime is coarsely crushed by using a crusher, etc. Then 0.05W5wt% metal salt of stearic acid (e.g. calcium stearate) is added to the crushed quick lime. The mixt, is ground by using a ball mill, an oscillating mill or a roller mill to bond the metal salt of stearic acid to the surface of the crushed quick lime particle, whereby the lipophilic nature of quick lime is improved. Then 1W20wt% extensible oil of naphthenic oil is added to the quick lime. The mixt. is subjected to a regrinding treatment to improve weathering resistance, whereby the desired dehydrating agent for rubbers or plastics can be obtd.
