Abstract

The invention relates to a magnetic anti-counterfeiting health-care material and a production method thereof. The magnetic anti-counterfeiting health-care material is formed in a mode that a layer of waterborne magnetic anti-counterfeiting health-care ink material is attached to the surface of an absorbable flexible substrate, wherein the waterborne magnetic anti-counterfeiting health-care ink is prepared according to the following formula: 10 to 40 percent of strontium-iron oxide micro powder; 0.1 to 5 percent of dispersing agent, 0.5 to 10 percent of colloid-protect reagent, 1 to 5 percent of thickening thixotropic agent, 10 to 50 percent of polyurethane emulsion, 0.1 to 3 percent of cross-linking agent, 30 to 65 percent of water, 1 to 5 percent of color paste and 0.05 to 1 percent of hydrophilic agent. The obtained magnetic anti-counterfeiting health-care material is a flexible coiled material with attractive appearance, strong anti-counterfeiting concealment and hydrophilic surface. The defects of single color, unattractive appearance, poor anti-counterfeiting concealment, hydrophobic surface and odor of a residual solvent of a material in the prior art can be overcome.

Description

Technical field: [0001] The invention relates to a magnetic anti-counterfeiting material, in particular to a magnetic anti-counterfeiting health care material with strong anti-counterfeiting concealment, beautiful appearance and hydrophilic surface and a production method thereof, which are widely used in the field of disposable sanitary products and packaging. Background technique: [0002] Magnetic anti-counterfeiting is a commonly used technology in the field of anti-counterfeiting. CN201010506836.0 is a magnetic nano-offset printing ink, and CN2004100006554.9 magnetic ink patents all use nano-ferric oxide to produce magnetic anti-counterfeiting inks. In addition to the anti-counterfeiting function, magnetic materials also have the function of magnetic therapy and health care, and are also widely used in disposable sanitary products. CN200710150697.0 negative ion magnetic sanitary napkin, CN200910195061.7 far-infrared magnetic health sanitary napkin, in these two patents,...
