Description
Technical field
The invention belongs to light industry, chemical material field; It is the method that base-material prepares the good long-afterglow luminescent paint of over-all properties with the ACRYLIC EMULSION that the present invention is specifically related to a kind of.
Background technology
Long-persistence luminous is a kind of photoluminescence phenomenon, is meant that stopping to shine the back material at exciting light still can continue luminous phenomenon.The luminescent material difference, the performance of decay of luminescence differs widely, and the material light emission continuation time that has is very short, and the perdurability that has is then very long.Rare earth long-afterglow luminescent material is a kind of environment-friendly energy-saving material, it can be behind the energy that absorbs sunlight or light, portion of energy is stored, lentamente the form of energy stored with visible light discharged then, after light source is removed, still can send visible light for a long time.Utilize this characteristic to can be used as the lighting source at night and dark place, significant application value is arranged in fields such as building, traffic and national defence.
Long-afterglow luminescent paint mainly is divided into solvent-borne type and aqueous luminous paint two classes.The solvent-borne type long-afterglow luminescent paint is to be made by certain complete processing by a certain percentage by long after glow luminous material, organic resin, organic solvent and auxiliary agent etc.Solvent based coating often needs the range of application and the consumption of regulation strictness, and the harmful organic solvent that can volatilize during coating film forming, thereby its range of application is restricted.Compare with solvent based coating, the great advantage of water-borne coatings is the existence that greatly reduces the consumption of organic solvent or eliminated organic solvent basically, belongs to environmentally friendly coating.In addition, water-borne coatings becomes the focus of paint field research in recent years owing to have characteristics such as production and construction safety, not flammable, nontoxicity, free from extraneous odour, and aqueous luminous paint has vast potential for future development.
Two pieces of U.S.'s patents of invention have all been reported the luminous paint that is used for motorway, and its paint binder is acrylic acid modified urethane resin.This coating belongs to the water-based paint of non-solvent component, contains europium and the coactivated MAl of other rare earth ion
2O
3(M is one or more of Sr, Mg, Ca, Ba) luminophore is a kind of environmentally friendly road paint, can be used for the sign in the track and the sideline of motorway, and provide the pavement quality under the normal traffic condition.World Report (WorldReporter, 2000,1,18) has been introduced a kind of hydrophobic acrylic resin luminous paint peculiar to vessel in addition, and this coating adopts ZnS and SrAl
2O
4: Eu
2+Therefore two kinds of luminescent materials have the characteristics of zinc sulphide and strontium aluminate luminous material concurrently.Chinese invention patent (CN1084535A) has openly been introduced a kind of luminescent coating, and its luminescent material is europkium-activated alkali earth metal aluminate, and base-material is selected resins such as epoxy, alkyd, chlorinated polyvinyl chloride, trimeric cyanamide for use; Inst. of Marine Chemical Engineering and Shandong Lun Bo company are developing luminosity height, time of persistence length, nontoxic pollution-free, construction safety acrylic acid type energy stroage and liminous water paint easily jointly.
As seen from above, domestic aqueous luminous paint is in development, and the main drawback of existence has water tolerance, wears no resistance, and sticking power is not strong, and luminance brightness is inhomogeneous etc.Therefore, develop the important development direction that high performance aqueous luminous paint is present this field.
Summary of the invention
The objective of the invention is to the main drawback that exists at present aqueous luminous paint,, develop the luminous paint of the good and environmental protection of a kind of performance by utilizing three kinds of mutual graft polymerizations of monomer and selecting suitable admixtion.
In order to achieve the above object, preparation method of the present invention is to be ACRYLIC EMULSION by the high molecular polymer that three kinds of monomers form by the mutual polyreaction of initiator, with the binder resin of synthetic ACRYLIC EMULSION as coating, and interpolation luminescent powder, auxiliary agent and filler prepare multi-color long afterglow water borne luminescent coatings.
Three kinds of used monomers have the structure of formula 1 representative:
Formula 1
Wherein:
R
1Representing H atom or carbonatoms is 1～5 alkyl;
R
2Representing H atom or carbonatoms is 1～10 alkyl.
In the above-mentioned polymerization process, polymerization temperature is 60～100 ℃, and the reaction times is 5～20min.
Above-mentioned used initiator is the aqueous solution of ammonium persulphate, dibenzoyl peroxide or Diisopropyl azodicarboxylate, and its strength of solution is 0.01g/mL～0.02g/mL.
The used luminescent powder of above-mentioned preparation luminous paint is rare-earth activated alkali earth metal aluminate, is specially CaAl
2O
4: Eu, Nd, or SrAl
2O
4: Dy, Eu or SrAl
