Abstract
PURPOSE: To obtain a stable synthetic resin material, easily handleable with a high fluidity and without causing aggregation of the powder in the air and cracks due to expansion of the powder after filling, by using a pulverized converter slag wherein the free lime is eliminated by modifying treatment.
CONSTITUTION: A converter slag within the free lime is eliminated by modifying treatment, e.g. blowing a gas containing oxygen thereinto, is pulverized by a pulverizer to a particle size of preferably several tens of μ of less which is favorable for a filler. The resultant fine powder is then mixed with a synthetic resin and molded. Even the modified slag in a high filling ratio over 200pts.wt. per 100pts. wt. the synthetic resin can be readily molded.
EFFECT: A stable synthetic resin composite material of high specific gravity can be obtained since an unstable component reactive with moisture or CO2 permeating the resin is not contained.
