Abstract
The invention discloses a rare-earth phosphate noctilucence powder coating. The coating is prepared from, by weight, 60-70 parts of basis resin, 10-20 parts of fillers, 10-15 parts of curing agents, 2-5 parts of auxiliaries and 5-10 parts of rare-earth phosphate. All the raw materials are stirred in a mixing machine at the speed of 1000 revolutions per minute for 10 minutes and extruded in a melting mode through a double-screw extruder, cooled, crashed and then sieved for grading, and the rare-earth phosphate noctilucence powder coating is prepared. The rare-earth phosphate noctilucence powder coating has the advantages that the technology is simple, repair is not needed due to the fact that the coating is integrally mixed with paint, the high luminous efficiency and luminous intensity are achieved, and the luminous time is long.
Description
Technical field
The present invention relates to art of powder coatings, what be specifically related to is a kind of RE phosphate noctilucent powder paint.
Background technology
Powder coating be one not containing solvent, 100% solid powdery coating, have solvent-free, pollution-free, recyclable, save the energy and resource, reduce labor intensity and film physical strength high, be a kind of novel material of novel, environmental protection.Widely using in recent years along with powder coating, various functional powders coating products is developed in succession, increases rapidly.
Emergent instructions in interior/exterior decoration, Pointing sign board, public place etc. then need the powder coating with noctilucence as the place of cue mark, at present, prior art is all smear layer of fluorescent powder coating coating surface, but along with the passing of duration of service, phosphor powder layer easily comes off, need to repair, social cost therefore can be caused to strengthen, and serious also can cause serious security incident.
In recent years, also have and add alkaline earth aluminate as luminous agent in coating, but must add the 30-40% of amount at original material of alkaline earth aluminate, cost sharply increases, and luminous efficiency and luminous intensity lower, fluorescent lifetime is shorter.
Summary of the invention
The object of the invention is the deficiency in order to solve the problems of the technologies described above existence, provide a kind of technique simple, be mixed into one with coating and need not repair and there is high luminous efficiency and luminous intensity, a kind of RE phosphate noctilucent powder paint that fluorescent lifetime is long.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of RE phosphate noctilucent powder paint, the component of original material and weight ratio are: base resin 60-70 part, filler 10-20 part, solidifying agent 10-15 part, auxiliary agent 2-5 part, RE phosphate 5-10 part.
Preparation method of the present invention is: according to the component of original material and weight ratio be: base resin 60-70 part, filler 10-20 part, solidifying agent 10-15 part, auxiliary agent 2-5 part, RE phosphate 5-10 part, in mixing machine, the speed of 1000 revs/min stirs 10 minutes, twin screw extruder is utilized to melt extrude, pulverize after cooling, carry out classification after sieve, this RE phosphate noctilucent powder paint can be obtained.
Wherein base resin comprises one or more in vibrin, epoxy resin, acrylic resin, urethane resin.
Wherein filler comprises one or more in barium sulfate, calcium carbonate, mica or silica powder.
Wherein auxiliary agent comprises one or more in matting agent, flow agent, high photo etching, ethylene oxide wax, catalyzer.
Wherein Eu as the rare earth ion of active element in RE phosphate
3+, Tb
3+, Sm
3+, La
3+, Ce
3+in one.
Wherein the size-grade distribution of RE phosphate is being less than 0.1 μm, 0.1 μm-10 μm, the grain size intervals in 0-0.044mm, 0.044mm-0.074mm, 0.074-1mm.
The part granularity of RE phosphate is close to nanometer, and specific surface area significantly increases, and light-emitting particles quantity significantly increases, and luminous efficiency and luminous intensity significantly strengthen; In addition because particle size is less than the wavelength exciting or launch light wave, therefore light field can be approximated to be uniformly in particle range, does not exist the microcavity effect caused by the confinement effect of light wave; The RE phosphate that the present invention is used in addition not all with ultra-fine grain, be that consider can be cost-saving.
Beneficial effect of the present invention:
The present invention is by formula combination and optimization, in powder coating, use the RE phosphate of steady persistence as fluorescent material, after the natural light being subject to 10-20 minute or light-illuminating, just can at noctilucence and reflective, there is high luminous efficiency, fluorescent lifetime can reach 12-15 hour, and luminous intensity can reach 800-1000cd/m
2, the place of indoor and outdoor as cue mark can be widely used in, meet the demand of practical application.
