Abstract

PURPOSE: To produce hydrophobic granular powder by uniformly mixing hydrophilic inorg. powder with metal hydroxides and milling them after which mechanochemical reaction with methylhydropolysiloxane oil is carried out to form a silicone resin film on the surface of the above powder by cross-linking polymn.
CONSTITUTION: Less than 10wt% of one or more kinds of metal hydroxides such as Mg(OH)2 and MgO is added to one or more kinds of hydrophilic inorg. granular powders such as mica, kaoline and talc, mixed, and milled to uniformly stick the hydroxide to the surface of the powder. Methylhydropolysiloxane oil of SiH equivalent less than 550 is then added to the powder in a rate of 3W7mg/m3, uniformly mixed by a ball mill or the like without heating, and milled to form a silicone resin film on the surface of the powder by cross-linking polymn. Thus, hydrophobic granular powder with no discoloration is obtd. contg. no silicone resin particles, that is, having a particle size almost equal to that of the raw material powder
