CALSIUM CARBONATE FILLER HAVING NANO-CAPSULE, PREPARING METHOD THEREOF AND PLASTIC RESIN COMPOSITION CONTAINING THEREOF

摘要

PURPOSE: A method for producing calcium carbon nanocapsule filler and a plastic resin composition are provided to reduce weld line of plastic molding form. CONSTITUTION: A method for producing a calcium carbon nanocapsule filler and a plastic resin containing the same comprises: a step of mixing 98-99.8 weight% of calcium carbone with 10-50 nm of average diameter, 0.2-2 weight% of stearic acid then stirring; a step of adding 50-150 weight parts of mixture based on 100 weight parts of styrene monomer; and a step of adding polymerization initiator to the monomer mixture.
