Specific embodiment
The invention provides a kind of modified RE light conversion agent high molecular polymer agricultural film, includes rare-earth light-converting in its component
Material high molecular polymer, the rare-earth light-converting material high molecular polymer are graininess, granular rare-earth light-converting material height
Molecularly Imprinted Polymer is one or more layers inert material of Surface coating, makes the core/shell type modified RE light conversion agent of surface-coating
High molecular polymer.
Wherein, the one kind during the inert material is as follows：
(1) inorganic matters：One layer of oxide or inorganic salt film are deposited in particle surface, with oxide surface cladding be
It is main；
(2) Organic substance：High molecular polymer is directly or indirectly in the method for particle surface cladding.
The modified method of high molecular polymer in the present invention, including it is as follows：
(1) polymer coating directly
Polymer coating directly be merely by organic polymer under certain condition directly peplos in luminescent powder surface.
Following two cladding modes are broadly divided into according to macromolecule is different from granule combination:Particle surface physical absorption, granule
Surface chemistry is bonded.
Using adsorption layer instrumentality mechanism, using organic polymer sedimentation, in red illuminating material CaS:Eu2+'s
Surface physics coats one layer of silicone resin film, and after cladding, on the basis of original fluorescence property is kept, chemical stability is obvious for sample
Increase.
Long persistence luminous polypropylene fiber is made using thermoplastic polypropylene and luminous pigment rare earth aluminic acid salt blend,
Obtained luminous polypropylene fiber has good storage light performance and good physical and mechanical propertiess.
In order to improve cladding of the macromolecule in particle surface, fluorescent material is added to into water miscible vinyl methyl ether and cis
In the copolymer solution of anhydride maleique, there is mating reaction in the COO- in high molecular polymer and Ca2+, adjust pH with NH4OH
Be worth the simple post processings of more than 9, Jing macromolecule layer can be formed in phosphor surface.
Polymer coating directly is simple to operate, and coating function power is relatively weak, and coating thickness is difficult to control to, and cladding is not
Uniformly.Rare earth luminescent material is difficult to be dispersed in polymeric matrix, can affect the macromolecular material system for finally preparing
The luminescent properties and mechanical performance of product.
(2) the modified method of surface direct polymerization
Direct polymerization modified method in surface is that polyreaction occurs after luminescent powder surface adsorbs polymerisable monomer to form company
The continuous and polymer of densification is so as to realizing modified method, also referred to as in-situ polymerization.
In-situ polymerization mode mainly has two kinds：There is polymerization in surface adsorption monomer, i.e., cause under heating or illumination condition
Agent produces radical polymerization；Excitating surface active site, induction monomer polymerization, i.e. luminescent powder surface Organic substance active site
Initiated polymerization itself.
With aluminate as substrate, divalent europium is activator, and trivalent dysprosium ion is the rear-earth-doped aluminic acid of coactivator
Strontium class luminescent material-SrAl2O4:Eu2+, Dy3+ (SAO-ED), luminosity is big, efficiency high, length persistence, without radiation
Property element, is a kind of novel inorganic luminescent material and energy-conservation " green " light source.In order to prevent luminescent powder from hydrolyzing in humid air, use
Acrylic acid (AA) by interfacial coordination method pretreatment SAO-ED luminescent powders, using emulsifier-free emulsion polymerization in its in situ Polymerization
Cladding polymethyl methacrylate, forms PMMA/SAO-ED recombination luminescence powder, and the water resistance of recombination luminescence powder is significantly improved.
Glycol/water is adopted for disperse medium, with potassium peroxydisulfate as initiator, by AA/MMA polyreactions, is obtained
PMMA coats strontium aluminate luminescent powder.As a result show, impact of the clad to the luminescent powder characteristics of luminescence is less, luminescent powder after cladding
The significant raising of resistance to water；In organic solvent
Used in trichloroacetic acid to NaYF4:After Yb, Er/NaYF4 host material carries out surface active, AA, initiator are added
Deng reactive polymeric, obtain recombination luminescence nanoparticle after finally certain hour being reacted with a small amount of glutaraldehyde solution again.It is compound to receive
Good dispersion of the rice corpuscles in water, does not also affect on its fluorescence property.Using situ aggregation method to luminescent powder CaS:Ce enters
Row cladding, a small amount of water adsorbed using a certain amount of monomer α-cyanoacrylatealkyl and luminescent powder surface are reacted, raw
Into corresponding polymer deposition luminescent powder surface formed clad, this polymerization can be with repeated several times, so as to increase cladding
The thickness of layer, about 0.7 μm of coating thickness.
Compare with polymer coating directly, the even particle distribution that direct polymerization modified method in surface is obtained, surface covers
Degree is high, and polymer film thickness is adjustable.
(3) surface grafting polymerization method
Organic coating can not only improve the water resistance of powder body, moreover it is possible to improve luminescent powder and organic system to a certain extent
The compatibility, its weak point be the water resistance of organic coating layer not as inorganic coating layer, using surface grafting polymerization
Method can make up this shortcoming.Because there is substantial amounts of hydroxyl or unsaturation in some inorganic particulates (such as SiO2, Al2O3 etc.) surface
Key, is generally first surface-treated to this kind of particle using silane coupler, forms polymer overmold network.In order to further carry
The water proofing property of high powder body, and luminescent material and the matrix resin compatibility so that luminescent material is dispersed by silane coupler
KH570 pretreatment luminescent powders, make polymerisable double bond on powder surface band, then using graft emulsion polymerization method, allow KH570
The particle for processing is polymerized under initiator effect with monomer MMA, so as to the SrAl2O4 for being coated with PMMA is obtained:Eu2+ rare earths
Luminescent material.
First rear-earth-doped strontium aluminate long-afterglow luminescent materials Surface coating silicon-aluminium binary film, increases clad and strontium aluminate
Adhesive force, then with the hydrophobic rare earth long-afterglow material that surface band unsaturated double-bond is obtained after silane coupler modified, then
In-situ emulsion polymerization is carried out with acrylic ester monomer or styrene monomer and obtains polymer compound rare-earth long after glow luminous material.
Modified luminescent powder, in adding macromolecular material matrix resin, gives macromolecular material long afterglow performance.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications, these improvements and modifications can also be made
Also should be regarded as protection scope of the present invention.
