Compared with prior art, artificial luminous grass provided by the invention, it is as albescent noctilucence court functional line, and this functional line energy long-time (at least 8 hours) is luminous, and the crowd of convenient motion played football at night.Because bright pedaline can protect the strong UV of careless line reduce on the impact of careless line, increase service life.Noctilucent material itself need to be after being subject to the irradiations such as natural daylight, daylight light, ultraviolet light, luminous energy is stored, after stopping irradiation, discharge in the mode with fluorescence lentamente, if pedaline need to store luminous energy, the grass silk just can not be done with too dark color, otherwise luminous energy can't enter careless line inside, can't make atomic excitation, the energy level transition of rare earth element, finally make the luminescent material can't be luminous.
Luminescent powder usually is divided into the photo-induced energy storage luminescent powder and is with active luminescent powder two classes.The photo-induced energy storage luminescent powder is that fluorescent material is after being subject to the irradiations such as natural daylight, daylight light, ultraviolet light, luminous energy is stored, after stopping irradiation, discharge in the mode with fluorescence lentamente, so at night or dark place, still can see luminously, the duration reaches several hours to tens hours.Being with active luminescent powder, is to mix radioactive substance in fluorescent material, the rays excite light-emitting phosphor that utilizes radioactive substance constantly to send, and this class luminescent powder fluorescent lifetime is very long, but the ranges of application such as poisonous and harmful and environmental pollution are little.
Fluorescent material divides inorganic fluorescent material and organic fluorescence materials, inorganic fluorescent material be represented as rare earth luminescence and rare-earth luminescent material, its advantage is that absorbability is strong, conversion ratio is high, the narrow emission of rare earth compounding central ion is conducive to panchromatic demonstration, and physicochemical properties are stable.Because rare earth ion has abundant energy level and 4f electron transition characteristic, makes rare earth become luminous treasure-house.Rare earth is because of its special electron structure, and has the incomparable spectral quality of general element, rare earth luminous nearly cover the category of whole solid luminescence, as long as speak of luminously, almost be unable to do without rare earth.The atom of rare earth element has the 4f5d electron configuration that is subject to extraneous shielding of underfill, therefore abundant electron energy level and long-life excitation state are arranged, nearly more than 20 ten thousand in energy level transition passage can produce diversified radiation absorption and emission, consists of widely luminescent material.
At present, common inorganic fluorescent material is sulfide (such as ZnS, the CaS) aluminate (SrAl2O4 with alkaline-earth metal, CaAl2O4, BaAl2O4) etc. as luminous host, with rare earth lanthanide [europium (Eu), samarium (Sm), erbium (Er), neodymium (Nd) etc.] as activator and co-activator, with the material of alkaline earth sulfide aluminate as luminous host, because for a long time use of sulfide own can pollute, therefore, can be widely used in each field with the rare earth element aluminate as the luminescent material of luminous host.
Noctilucent material applies in the pedaline prescription as functional aid, directly adds luminescent powder in the wire drawing prescription in initial selection experiment, and powder lot dispersing is inhomogeneous, the easy fracture of wire of wire drawing, and also the grass silk of final molding is substantially not luminous.Therefore before wire drawing, need first with the luminescent powder granulation, make resin parcel noctilucence powder, material enters even extruder during wire drawing, simultaneously, noctilucence grass line color can not be too dark, Masterbatch toner amount need reduce, otherwise it is inner that light source is difficult to enter careless line, luminescent powder can't store luminous energy, observes even store luminous also being difficult to of luminous energy.
Noctilucence grass line absorbs light source daytime, discharges light source evening, and it is lower that the basic whole day of careless line is in the light irradiation, and is also corresponding higher to the weatherability requirement, so the anti-UV composition of this careless line is higher than the careless line of routine.The noctilucence product thickness is also particularly important on the impact of the luminous degree of grass silk, and experiment shows, the careless line luminous intensity that thickness is higher than 200 μ m is than being lower than the strong more than 20% of 200 μ m, and service life is also long.
