Description

A kind of magnetic anti-counterfeiting health-care material and production method thereof
Technical field:
The present invention relates to a kind of magnetic anti-counterfeit material, particularly relate to a kind of false proof disguise strong, appearance looks elegant, the magnetic anti-counterfeiting health-care material of surface hydrophilic and production method thereof, be widely used in disposable sanitary articles and packaging field.
Background technology:
Magnetic anti-counterfeit is a kind of technology generally adopted in anti-counterfeit field, CN201010506836.0 magnetic nano offset printing ink, all adopts nano ferriferrous oxide to produce magnetic anti-forge printing ink in CN200410006554.9 magnetic ink patent.Magneticsubstance, except there being anti-fake effect, also having the effect of Magnetotherapeutic health, also widely uses in disposable sanitary articles.CN200710150697.0 anion magnetic sanitary towel, CN200910195061.7 far-infrared magnetic health-care sanitary towel, adopts and martial ethiops micro mist is made functional agglomerate in these two patents, spinned fiber, acupuncture becomes magnetic non-woven fabrics again, for health care, is not applied to false proof.
The current disposable sanitary articles market of China is still made up of multiple manufacturer, but the market concentration is more and more higher, wherein the market share of front 15 sanitary towels/sanitary pad manufacturer reaches 61.8%, the whole industry of current disposable sanitary articles comes to the ripening period, market competition is very fierce, because medium and small sized enterprises are at starting material, particularly substantially do not fix a price above import starting material, the power of negotiating a price, survival pressure is very large, manage the channel reseller of minor brands or small business to survive, the phenomenon of imitated personation famous brand name can get more and more.In famous brand name product false proof measure baseset on outer packaging bag, reached the object of protection by various anti-forgery ink printing.And at sanitary towel, protection pad directly adopts the manufacturer of anti-counterfeiting technology considerably less.
Patent CN200910107654.3 adopts ink colour developing principle and technology to come false proof, utilizes sanitary towel sublevel load anti-counterfeiting chip to reach false proof object.Above anti-counterfeiting technology is applied to disposable sanitary articles and all there is following defect: 1. more than, various ink mainly does carrier with organic solvent, for non-absorbing ground, such as PET, PVC, PP, aluminium foil, and disposable sanitary articles material is Absorbable rod ground, printing area is large, solvent just cannot volatilize totally, causes scent of; 2., after oil-based ink is dried, surface hydrophobicity, affects transmissibility and the absorptivity of disposable sanitary articles; 3. the false proof disguise of ink is not strong, easily copies; 4. unsightly, magnetic ink colors black, brown in the majority, having other colors, is also deeply blackish green, intense violet color.
Water-based magnetic anti-counterfeit health care ink can solve the problem.Ferromagnetic oxide powder is the most inexpensive magnetic, but its color is dark, with black, dark brown is in the majority, reach maximum magnetic property with minimum addition, the impact reducing the Color pair Absorbable rod flexible parent metal of magnetic itself improves false proof concealed key, and it is feasible for improving magnetic magnetic energy product.Magnetic, because natural N pole and S pole, attracts each other, and is easy to reunite, and magnetic property is higher, reunites more severe.Prior art solves magnetic and reunites and take magnetic to be dispersed in nonpolar, insulating carrier, silicone oil. kerosene, paraffin oil, mineral oil are common selections.Water belongs to polarity, conductor carrier, and magnetic is reunited very serious in water, and high force dispersion is opened, and moment can condense again.
Summary of the invention:
The invention reside in and a kind of magnetic anti-counterfeiting health-care material is provided, appearance looks elegant, false proof by force hidden, the flexible web of surface hydrophilic.Can overcome prior art utilizes magnetic anti-forge printing ink to process, and material color is single, and unsightly, false proof disguise is poor, and surface hydrophobicity has the defect of residual solvent smell.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of magnetic anti-counterfeiting health-care material, it is characterized in that a kind of flexible web, be at Absorbable rod flexible parent metal surface attachment one deck water-based magnetic anti-counterfeit health-care oil ink material, wherein water-based magnetic anti-counterfeit health care ink is according to making of filling a prescription as follows:
Strontium-ferrite micropowder: 10-40%, dispersion agent: 0.1-5%, colloid protective agent: 0.5-10%, thickening thixotropic agent: 1-5%, polyaminoester emulsion: 10-50%, linking agent: 0.1-3%, water: 30-65%, mill base: 1-5%, hydrophilizing agent: 0.05-1%.
Strontium-ferrite micropowder is characterised in that particle diameter is between 0.5-10 micron, ferritic primary sintered material.Wherein dispersion agent can be sodium polyacrylate, ammonium polyacrylate, sodium lignosulfonate, Yelkin TTS, sodium laurylsulfonate, in sodium oleate wherein one or more.Wherein thickening thixotropic agent can be Lalgine and derivative thereof, Natvosol, polyacrylic acid and derivative thereof, xanthan gum, polyacrylamide, organobentonite, polynite, in aerosil wherein one or more.Wherein linking agent can be melamine resin, aziridine and derivative thereof, in blocked isocyanate wherein one or more.
There is wetting ability on flexible web surface, water in surface penetration time of flexible web between 0.5 ~ 3 second.
Absorbable rod flexible parent metal can be paper, nonwoven material, any one in textile materials, textile materials can be woven fabric, woven cloth, any one in looped fabric, nonwoven material can be needle punched non-woven fabrics, spunlace non-woven cloth, immersion non-woven fabrics, fabric hot rolled nonwoven fabrics, spun-bonded non-woven fabrics, any one in melt spraying non-woven fabrics.
Flexible parent metal transferred to by water-based magnetic anti-counterfeit health care ink can be one or more in screen printing, gravure, offset printing, convex print and flexo and roll coating model.
The present invention prepares magnetic anti-counterfeit health care coiled material, adopts following steps:
A adds water in stainless steel scuffing of cylinder bore, opens high speed dispersor, adds dispersion agent at a slow speed in order, colloid protective agent, strontium-ferrite micropowder, thickening thixotropic agent, reinforced end, high speed dispersion 30 minutes;
Made for step A slurry is added sand mill and grinds by B;
C adds water in stainless steel scuffing of cylinder bore, opens high speed dispersor, adds colloid protective agent at a slow speed in order, thickening thixotropic agent, the made ground slurry of step B, linking agent, emulsion, mill base, hydrophilizing agent, high speed dispersion 30 minutes;
Made for step C water-based magnetic anti-forge printing ink shifts on Absorbable rod flexible parent metal by D, dries;
E uses cutting machine that Absorbable rod flexible parent metal is cut into appointment specification.
Beneficial effect of the present invention is: utilize strontium-ferrite raw material and sintering process, controls the pigmenting tendency of strontium-ferrite micropowder, in conjunction with size controlling, obtains magnetic energy product relatively the highest, strontium-ferrite micropowder that color is relatively the most shallow.Utilize macromolcular dispersant between magnetic, set up three-dimensional mask space, utilize colloid protective agent to strengthen 3 D stereo network, then fix magnetic cyberspace by thixotropic agent, solve the problem of permanent magnetic powder cohesion conglomeration in aqueous carrier very well.Obtain a brightly painted water-based magnetic anti-counterfeit health care ink like this, transferred to Absorbable rod base material, after oven dry, can obtain a magnetic anti-counterfeit disguised strong, appearance looks elegant, has the flexible web of certain health-care effect, its surface hydrophilic, can be widely used in disposable sanitary articles.
