▎ 摘 要
NOVELTY - Geomagnetic functional negative oxygen ion material is prepared by adding 0.4-0.6 kg negative oxygen ion powder, 1.2-1.4 kg tourmaline powder, 1.4-1.6 kg gypsum powder, 1.4-1.6 kg kaolin, 0.01-0.03 kg graphene powder, 0.6-0.8 kg calcined kaolin, 0.4-0.6 kg yellow river jade powder, 0.3-0.7 kg palermo stone powder, 0.3-0.7 kg opal powder and 0.04-0.06 kg citric acid to every 1500 ml ethanol aqueous solution. USE - The geomagnetic functional negative oxygen ion material is used for recreational vehicle and indoor. ADVANTAGE - The geomagnetic functional negative oxygen ion material has high safety and healthcare effect on human body and applicability, stabilizes negative oxygen ions in the RV to an average release concentration of more than 6000/m3 and reduces amount of graphene used. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the geomagnetic functional negative oxygen ion material, which involves (a) adding palermo stone powder and opal powder to 30-35% ethanol aqueous solution and soaking for 15-30 minutes to obtain a magnetic ionization mixture, (b) adding graphene powder to the magnetic ionization mixture and allowing to stand for 20-30 minutes to obtain ionization reactant (I), (c) adding yellow river jade powder, tourmaline powder and remaining amount of ethanol aqueous solution to the ionization reactant (I), evenly stirring the mixture, then adding kaolin, negative oxygen ion powder and citric acid, stirring and reacting for 8-12 minutes, then allowing to stand for reaction 25-35 minutes to obtain ionization reactant (II), (d) adding calcined kaolin and gypsum powder to the ionization reactant (II), stirring and adjusting to a thick shape to obtain the ionization reactant (III), (e) adding the ionization reactant (III) into a mold, tapping and leveling, (f) adding putty powder and lime mud mixed with ethanol aqueous solution on the surface of the ionization reactant (III), leveling, allowing to stand and solidifying to obtain a geomagnetic functional negative oxygen ion material, where the ethanol aqueous solution has 80-90 %mass.
