Abstract
The present invention is a kind of luminophore composition that contains phosphor, is combined by zinc sulphide and cupric sulfide and a certain amount of activator.This material has stronger luminosity, continues fluorescent lifetime in the dark and can reach 12 hours, can be widely used in industries such as safety, building, electrical equipment, public transport, textile printing and dyeing, exploitation, production.This material is "dead", nontoxic, with composition of matter of the present invention mix can be made into luminescent plastics, luminous paint in synthetic resin moulding compound or the coating after, can be made into various luminous articles for use.
Description
The present invention relates to embedded photoluminescent material, specifically a kind ofly contain the luminophore composition of phosphor and this luminophore composition is applied to be prepared into luminescent plastics, luminous paint.
Along with people's material, the level of cultural life improve constantly and abundant, beautify life, the requirement of providing amenities for the people are more and more high, special evening in dark, no matter in the street, the square, still at home, people wish to have some without power supply automatic luminous cue mark so that seek target easily.In the prior art, existing various luminescent material compositions or luminous pigment are used in daily life.As having disclosed a kind of luminous compositions in the Chinese patent 3-30 phase communique, it is formed through melting by the vitriol of fluor and alkaline-earth metal, wherein, (composition formula is Ln2O3:Eu to fluor by the higher rare-earth oxide fluor of some prices, wherein Ln is Y, Gd, La, at least a among the Lu); Vitriol is BaSO4 or SrSO4.The twinkler constituent of this invention has the high and cheap characteristics of brightness.The special recommendation of this twinkler constituent is used for luminescent lamp, has high color rendering in order to the luminescent lamp of making.
Existing various luminous pigment has high-visibility pigment and phosphorescent pigment etc., in order to give material painted or make coating, be used to paint, the painted and textile printing of printing ink, plastics etc., or brushing navigation, instrument and be used for road sign, fire-protection device and antiaircraft aisle etc. and make safety notice.But existing these luminous pigments, particularly photoluminescence material, its luminous intensity is relatively poor, and it is shorter to continue the luminous time especially in the dark.So wishing has some luminosity height, luminous longer duration, does not contain radioactivity and cheap luminophore, they are used for daily plastics and coating, make these plastics and coating can send the light of high brightness in the dark more enduringly, it is various required to live for people.
The objective of the invention is for the embedded photoluminescent material of a kind of luminosity height, luminous longer duration is provided, and in order to make can be luminous plastic pellet and coating.
As everyone knows, zinc sulphide (ZnS) generally is to be fed zinc solution and got by hydrogen sulfide, and zinc sulphide then can be made into white pigment, luminescent powder.Its luminosity of independent zine sulfide pigment is not high, and the luminous hold-time also soon.
To achieve the above object of the invention, the applicant is through concentrated research trial, discovery mixes with the cupric sulfide of 70-30 weight part with the zinc sulphide of 30-70 weight part, and the uranine of the lithium of the 2.5-7.5% of adding total amount and 1.5-3.5% is as activator, through 400 ℃ of-1400 ℃ of temperature sintering, zinc sulphide cupric sulfide luminophore composition.
Go in the Plastic Resins such as PVC, PE, PP with luminophore fusion of the present invention, can obtain the luminescent plastics particle.Through multiple scheme test relatively, zinc sulphide cupric sulfide luminophore composition fusion with the 28-55 weight part is gone in the plastic powders of 72-60 weight part, and the auxiliary agent of the 3-5% of adding total amount, can make luminescent plastics particle more of a specified duration of stronger and luminous time length of luminosity.
Equally, concoct varnish, can make stronger, the luminous time length luminous paint more of a specified duration of luminosity into the 30-25 weight part with the zinc sulphide cupric sulfide composition of 70-75 weight part.
The present invention will be described in more detail below in conjunction with embodiment.
Embodiment 1.
Select the zinc sulphide of 30 weight parts and the sulfuration copper powder of 70 weight parts for use, make it to mix, mixing all, the back baked two hours with 100 ℃ of temperature, taking out the cooling back soaked three hours with normal-temperature water, fall to do to soak water and filter and do the back with 100 ℃ of temperature oven dry, be milled into 150 order powder then, then drop into 3% lithium of its gross weight and 2% uranine as activator, fully stir back input pure water with stirrer and carry out precipitation process, to complete post precipitation taking-up throw out, carried out sintering four hours with 400 ℃ of temperature, after cooling to grind to form 320 order powder.Zinc sulphide cupric sulfide composition and the existing zinc sulfide luminescent powder made are opposed than test, see that its luminosity increases by 160%, continue fluorescent lifetime in the dark and can keep 8 hours.
Embodiment 2.
Select the zinc sulphide of 50 weight parts and the sulfuration copper powder of 50 weight parts for use, the method for employing is identical with embodiment 1, but the lithium that drops into is 5% of a gross weight, and uranine is 3% of a gross weight, and high temperature sintering is 3.5 hours under 800 ℃ of temperature.The zinc sulphide cupric sulfide composition of making, its luminosity increases by 250%, and the luminous time length can keep 12 hours.
Embodiment 3.
Select the zinc sulphide of 60 weight parts and the sulfuration copper powder of 40 weight parts for use, the employing method is identical with embodiment 1, and the lithium of input is 7% of a gross weight, and uranine is 3% of a gross weight, and sintering is three hours under 1400 ℃ of high temperature.The zinc sulphide cupric sulfide composition of making, its luminosity increases by 260%, and lasting fluorescent lifetime was kept 12 hours.
The embodiment of luminophore composition of the present invention is comprehensive as table one.
Embodiment 4.
Employing is as the luminophore composition of component as described in the embodiment 2, and blending goes into to make the luminescent plastics particle in the polyvinyl chloride powder.Select this luminophore composition of 28 weight parts and the polyvinyl chloride powder of 72 weight parts for use, fully stir, after order is thrown in the auxiliary agents such as stablizer (T890), 0.8% mixture (PDOP), 1% lubricant (stearic acid) and 2% modified resin of gross weight 1% simultaneously, adopt to make the general working method of plastic pellet, just obtain having higher brightness and than the luminescent plastics particle of long hair between the light time.Gained luminescent plastics particle and embodiment 2 described luminophore compositions compare test, and its luminosity is similar substantially to the time length.
