▎ 摘　　要

NOVELTY - Aldehyde deodorizing additive comprises graphene, medical stone, nano silver, silicon emulsion, inorganic oxide, fluorocarbon emulsion, thickener and water as raw material components. USE - Aldehyde deodorizing additive for addition in an indoor paint, a purification device, a laundry bactericide or an indoor bactericide (claimed). ADVANTAGE - The aldehyde deodorizing additive has simple process, and is suitable for large scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an aldehyde deodorizing additive, which involves: (A) heating water to a first temperature, adding the inorganic oxide under high-speed dispersing and stirring, stirring and dispersing to obtain mixture; (B) adding the graphene, medical stone, and nano silver sequentially to stir and disperse, and cooling to a second temperature to obtain composite; and (C) adding sequentially the silicon latex and the fluorocarbon emulsion in sequence, and after mixing and stirring, the thickener to obtain the aldehyde deodorizing additive.
