Abstract
The invention discloses a rare earth borate steady persistence polyester powder coating. The coating is prepared from, by weight, 60-75 parts of polyester resin, 5-10 parts of rare earth borate, 10-15 parts of curing agents, 5-20 parts of barium sulfate and 2-5 parts of auxiliaries. All the raw materials are stirred in a mixing machine at the speed of 1000 revolutions per minute for 10 minutes, extruded in a melting mode through a double-screw extruder, cooled, crashed and then sieved for grading, and the rare earth borate steady persistence polyester powder coating is prepared. The rare earth borate steady persistence polyester 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(rare earth) borate steady persistence polyester powder coating.
Background technology
Coating performance can be improved because powder coating has, reduce costs, eliminate the advantages such as the generation of volatile organic matter (VOC), hazardous air pollutants (HAP) and hazardous substance refuse and disposal, thus obtain in recent years and continue and increase rapidly.The production of powder coating over half at present utilizes vibrin as the important component part of film forming system.The range of choice of vibrin is very wide, and this makes the performance of powder coating wider, effectively can meet the service requirements of consumers in general like this.
Emergent instructions in interior/exterior decoration, Pointing sign board, public place etc. then need with the long powder coating of noctilucence, fluorescent lifetime 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 RE phosphate as luminous agent in coating, 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, there is provided 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(rare earth) borate steady persistence polyester powder coating that fluorescent lifetime is long.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of RE(rare earth) borate steady persistence polyester powder coating, the component of original material and weight ratio are: vibrin 60-75 part, RE(rare earth) borate 5-10 part, solidifying agent 10-15 part, barium sulfate 5-20 part, auxiliary agent 2-5 part.
Preparation method of the present invention is: according to the component of original material and weight ratio be: vibrin 60-75 part, RE(rare earth) borate 5-10 part, solidifying agent 10-15 part, barium sulfate 5-20 part, auxiliary agent 2-5 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(rare earth) borate steady persistence polyester powder coating can be obtained.
Wherein the acid number of vibrin is 30 ~ 50mgKOH/g, viscosity 3000 ~ 6000mPa.s, number-average molecular weight 2500 ~ 7500, second-order transition temperature 55 ~ 70 DEG C.
Wherein Eu as the rare earth ion of active element in RE(rare earth) borate
3+, Tb
3+, Sm
3+, Ce
3+in one.
Wherein solidifying agent comprises triglycidyl isocyanurate, the one in hydroxyalkyl amide.
Wherein auxiliary agent comprises matting agent, flow agent, high photo etching, one or more in ethylene oxide wax.
Wherein the granularity of RE(rare earth) borate is less than 0.1 μm.The part granularity of RE(rare earth) borate 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.
Wherein RE(rare earth) borate 5-10 part, when RE(rare earth) borate 5-8 part, luminous efficiency and luminous intensity strengthen gradually, when being 8 parts to RE(rare earth) borate, reach climax, and when RE(rare earth) borate 8-10 part, luminous efficiency and luminous intensity weaken gradually.
Beneficial effect of the present invention:
The present invention is by formula combination and optimization, use the RE(rare earth) borate of steady persistence as fluorescent material, after the natural light being subject to 5-20 minute or light-illuminating, can at noctilucence and reflective, luminous efficiency is high, fluorescent lifetime can reach 12-16 hour, and initial luminescence can reach 900-1200mcd/m
2, the place of indoor and outdoor as traffic instruction, sign flag can be widely used in, meet the demand of practical application.
