Restoration the conductive inorganic powder body and its production manner and the said conductive inorganic powder body, become the electrification prevention Characteristic high polymer materials

摘要

PURPOSE: To obtain the subject powder having high whiteness, capable of maintaining excellent antistatic properties for a long period of time by treating the surface of specific inorganic powder with a specified polymer. ;CONSTITUTION: (A) 100 pts.wt. powder of one or more inorganic substances of calcium carbonate and a silicate mineral (preferably talc, mica, etc.) are blended with 0.1-10 pts.wt. polymer of the formula (R₁ is H or methyl; M is alkali metal, ammonium or amine) so that the component B is adsorbed on the surface of particles of the component A to give the objective powder.;COPYRIGHT: (C)1994,JPO&Japio
