Abstract

The invention relates to a new type of long persistence glazing flame-proof paint. It is formed by long persistence glazing material, high chlorinated polyethylene (30%), chlrorinated rubber, 70% chlorinated paraffin, 50% chlorinated paraffin, antimony trioxide, dissimilar, gas-phase silicon dioxde, heavy aromatic hydrocarbons and butyl acetate. The used long persistence glazing material is one type of SrAl2O4: Eu, Dy, SrAl3O5.5:Eu, Dy, CaAl2O4:Eu, Nd, Y2O2S:Eu, Mg, Ti, CaS: Eu, Tm or SrS: Eu, Tm which sends green, blue and red light; the paint can absorb the light energy and send visible light to 5-12h with the flame-proof temperature 200 deg.

Description

Luminous flame-proof paint with long afterglow

Technical field

The present invention relates to a kind of fire retardancy that both had, have the new type long-persistence luminous flame-proof paint of overlength afterglow again.

Background technology

New type long-persistence luminescent material such as systems such as rare earth aluminate and yttrium oxysulfide are free of contamination energy-saving environmental protection storage luminescent material, they can be the energy storage that obtains down from irradiations such as sunlight, luminescent lamp, incandescent light material, discharge these energy lentamente with luminous form (in the dark can clearly see this light) then, thereby played the purpose of guidance lighting under dark situation, and this class long after glow luminous material is reusable.But, must be added in other the matrix such as plastics, coating and fiber and use because they are polycrystal powder materials.Luminous paint with overlength afterglow with its widely purposes caused people's attention, as being used for making street, guideboard, absorb the energy of sunlight or natural stray light daytime, evening is luminous, it is a kind of energy-saving material that can utilize sun power, so not only can save the energy but also can provide convenience, also can increase view to the city for the resident.Simultaneously, long-afterglow luminescent paint also can be used for aspects such as the fine arts drawing, decoration of the emergency escape Warning Mark in civil air defense constructions and installations, skyscraper, large-scale civic building, subway, mine etc. and low light level lighting system and building, store the energy of light such as fluorescent lamp at ordinary times, in the dark send out visible light, the fluorescent lifetime of green glow wherein, blue green light and blue light is sustainable more than 12 hours.At present, the patent of more existing long-afterglow luminescent paints.Yet concerning some important buildings such as civil air defense constructions and installations, skyscraper, large-scale civic building, subway, these places, mine, the coating of use often will have special performances, as flame retardant properties.Because common coating can discharge obnoxious flavour or even dense smoke as 50 ℃ when use temperature surpasses certain temperature, not only the place environment is polluted, when being in an emergency, also influence and evacuate and disaster relief work.Along with warming day by day of terrestrial climate, many southern cities can continue several weeks at 40 ℃ of annexes at the temperature in summer, and the surface temperature in noon street more reaches more than 50 ℃, and this will inevitably cause disadvantageous effect to the use with common long-afterglow luminescent paint.But present existing long-afterglow luminescent paint patent does not all relate to the luminous paint with flame retardant properties.

Summary of the invention

The purpose of this invention is to provide a kind of fire retardancy that both had, have the new type long-persistence luminous flame-proof paint of overlength afterglow again.

The used coating of the present invention consists of: long after glow luminous material, highly-chlorinated polyethylene (30%), chlorinated rubber, 70% clorafin, 50% clorafin, antimonous oxide, dispersion agent, aerosil, heavy aromatics, N-BUTYL ACETATE.Used long after glow luminous material is green, bluish-green, blue for emission, the SrAl of ruddiness ₂O ₄: Eu, Dy, SrAl ₃O _5.5: Eu, Dy, CaAl ₂O ₄: Eu, Nd, Y ₂O ₂S:Eu, Mg, Ti, CaS:Eu, Tm or SrS:Eu, a kind of among the Tm; And used long-afterglow material all is ground into 150-300 purpose powder in advance, and does not need ball milling in preparation coating process.Prepared luminous paint is owing to the difference of selected long after glow luminous material is launched from the steady persistence of royal purple, bluish-green, green or red color.The coating that makes in this way absorbs the luminous energy of sight, electricity-saving lamp etc., in the dark sends out visible light.As shining 30 minutes more than the sustainable 5-12 of its fluorescent lifetime hour with conventional fluorescent lamps.Resistance combustion temperature can reach 200 ℃.With highly-chlorinated polyethylene (30%), change rubber, 70% clorafin is the base-material of coating, also plays the effect of fire retardant simultaneously.50% clorafin is a softening agent, and antimonous oxide is whitening agent and fire retardant, and aerosil is an anti-settling agent; Heavy aromatics, N-BUTYL ACETATE are solvent.

Luminous flame-proof paint with long afterglow of the present invention can be used for aspects such as the fine arts drawing, decoration of the emergency escape Warning Mark in civil air defense constructions and installations, skyscraper, large-scale civic building, subway, mine etc. and low light level lighting system and building.
