超细高分散碳酸钙的原位制备及性能
In situ Preparation and Property of Superfine High-dispersal Calcium Carbonate
摘要
Abstract
High-dispersal hydrophobic CaCO3 nanoparticles were obtained by the surface modification of oleic acid(OA). The size of CaCO3 nanoparticles could be controlled within the range of 40—50 nm during the carbonation process of Ca(OH)2 slurry by CO2. The oleic acid grafted onto the surface of superfine calcium carbonate nanoparticles in situ surface modification, the dispersal state of CaCO3 nanoparticles was well im-proved. And surface state of CaCO3 nanoparticles was changed from hydrophilic to hydrophobic due to the con-tact angle of superfine CaCO3 filler was 125.96°. Adding 1%(mass fraction)superfine CaCO3 nanoparticles filler to ABS resin matrix,its whiteness increased from 62.47 to 87.96,which indicated that superfine CaCO3 filler can be widely used in"white home appliance"ABS resin.关键词
