BASE MATERIAL-SILICA SOL DRIED PRODUCT COMPLEX HAVING POSITIVE HOLE AND METHOD OF PRODUCING THE SAME

Japanese Patent JP2016068543

A

PROBLEM TO BE SOLVED: To provide a base material-silica sol dried product complex that exhibits a rapid antiviral action, a germicidal action, etc. under no light by treatment at the temperature containing ordinary temperature, and an applied article thereof.SOLUTION: Fibers, woven fabrics, nonwoven fabrics, papers, plastics, metals, glasses, refractories, bamboo charcoal, charcoal, or a composite thereof are used for a base material. A silica sol is applied on the base material and the resulting coated base material is dried in an atmosphere of 0 to 150°C to obtain a base material-silica sol dried product complex. Silica particles constituting the silica sol has 4 to 700 nm of a particle diameter. The adhesion amount of the silica sol based on the base material is 0.1 to 2.5 g/min a dry state.EFFECT: When a DMPO liquid drops down onto a nonwoven fabric that carries a dried silica sol under no light, a DMPO-OH radical is detected by an electron paramagnetic resonance (ESR) to verify the occurrence of a hydroxyl radical. A product is used as an air cleaning material in a wide range of fields, such as a hygienic mask, an air filter made into an element permeable to gas, medical and nursing clothing, and a partition.SELECTED DRAWING: Figure 2
