Description
Technical field
The present invention relates to a kind of preparation methods for shortening the phosphor slurry of energy-saving lamp time-to-climb.
Background technology
It is well known that low pressure UV bactericidal lamp and energy-saving lamp belong to low pressure gaseous discharge mercury lamp；Low pressure gaseous discharge
The discharge principle of mercury lamp is that energy jump occurs after mercury atom is excited, and mercury atom sends out two from high level into low energy order transition
Kind spectral line, one is 254nm spectral lines, another kind is 185nm spectral lines, and ultraviolet germicidal lamp is not due to being coated with barrier ultraviolet light
Phosphor powder layer, so ultraviolet light can be directed through glass-tube wall；And energy-saving lamp is because glass-tube inner wall is coated with the conversion of 254nm spectral lines
Fluorescent powder, so visible light can be sent out, 185nm by phosphor powder layer barrier because can not then be transmitted.
Time-to-climb refers to the 80% luminous flux required time when low pressure gaseous discharge mercury lamp light output reaches stable, is climbed
The speed for rising the time is decided by the mercury vapor pressure inside fluorescent tube, and usual mercury vapor pressure is higher, and time-to-climb is faster, namely when climbing
Between it is shorter；Mercury vapor pressure is lower, and time-to-climb is slower, i.e. time-to-climb is longer.It is closed using common liquid mercury lamp and Low temp amalgam
In golden lamp, because mercury vapor pressure is closer to the 0.8Pa needed for best light output, time-to-climb is all shorter, generally less than
30 seconds, star and the requirement of Europe EST standards of american energy can be reached.However, in the low pressure gaseous discharge using high-temperature amalgam
Lamp, because the amalgam release required temperature of mercury vapour is higher, generally higher than 95 DEG C, and fluorescent tube is in rigid burning point, where amalgam
Position temperature is relatively low, so the speed of its release mercury vapour is slower, is far below 0.8Pa so as to cause initial stage mercury vapor pressure, therefore
Light output is very slow, and time-to-climb is generally more than 120 seconds, and standard is not achieved and user requires.
Time-to-climb long method is solved in industry at present substantially by the way of Auxiliary amalgam, that is, uses high-temperature amalgam
As main amalgam, indium site is welded in and is immediated vicinity from filament position as Auxiliary amalgam by indium net, it is desirable to work in filament
When promote the indium mercury alloy of indium net quickly to be spread in fluorescent tube discharge space by the Joule heat that filament is brought, quickly carried to play
High mercury vapor pressure promotes light output and shortens the effect of time-to-climb.
But since Auxiliary amalgam spot welding position is too close from filament, when fluorescent tube is with duration and degree of heating sealing or clamp process, high temperature
Effect so that the indium of Auxiliary amalgam is partially oxidized already or all oxidations, i.e. indium has been oxidized to indium oxide, and indium oxide
Amalgam can not be formed with mercury, therefore does not have the effect for really assisting main amalgam to shorten time-to-climb in practical applications.
In addition, also have colleague to take shortens low-pressure gaseous discharge lamp time-to-climb in the mode of fluorescent powder or glass-tube wall addition indium powder,
It has little effect in fact, reason is identical as the above, because mixing indium on fluorescent powder or tube wall in energy-saving lamp and ultraviolet radiator
It is intended to decompose by roasted tube in processing and the superhigh temperature processes such as exhaust bake-out, temperature is more than 450 DEG C, at such high temperatures,
Indium is aoxidized already, subsequently can not form actually useful indium mercury alloy with mercury.

By a kind of preparation method for shortening the phosphor slurry of energy-saving lamp time-to-climb of this purpose design, feature
It is to include the following steps：
The yttrium oxide of nano-level sphere powder is added deionized water and dispersant, and quickly stirs 30~60 by step 1
Minute is configured to the first mixed liquor,
Wherein, the mass ratio of the yttrium oxide of nano-level sphere powder, ionized water and dispersant is 6~15：75~90：0.3
~2；
Step 2 by nano alumina powder jointed addition deionized water and surfactant, and quickly stirs 30~60 minutes
It is configured to the second mixed liquor,
Wherein, the mass ratio of alumina powder, deionized water and surfactant is 6~15：80~92：0~3；
Step 3, by the first mixed liquor and the second mixed liquor with 1：1 volume ratio at the uniform velocity stirs that obtain within 30 minutes third mixed
Close liquid；
Fluorescent powder is added in third mixed liquor by step 4, and at the uniform velocity stirs and be configured within 3~10 minutes the 4th mixing
Liquid；
Wherein, the mass ratio 12~36 of fluorescent powder and third mixed liquor：100；
Step 5, by the 4th mixed liquor, mass concentration be 5% PEO glue, deionized water mix after, at the uniform velocity stir 60~
120 minutes, obtain the 5th mixed liquor；
Wherein, the mass ratio 90~120 of the 4th mixed liquor, the PEO glue and deionized water that mass concentration is 5%：25~45：
25~40；
Step 6, surfactant is added at the uniform velocity to stir 1~5 minute in the 5th mixed liquor obtains phosphor slurry,

The present invention solves the problems in above-mentioned background technology, principle by adding the yttrium oxide of nano-level sphere powder
It is：
1) yttrium oxide of nano-level sphere powder does not absorb 254nm ultraviolet lights, and big to the transmitance of energy saving lamp grass tube
In 99.3%；
2) yttrium oxide of nano-level sphere powder is to mercury atom without absorbability, however the oxides such as aluminium oxide are to mercury atom
There can be certain absorbability, therefore the yttrium oxide of nano-level sphere powder discharges the ability of mercury atom more compared to aluminium oxide
By force；
3) after the yttrium oxide film forming of nano-level sphere powder, grain size is nanoscale, spherical arrangement than aciculiform and its
His form is finer and close, therefore the mercury atom inside fluorescent tube can not penetrate into the gap of phosphor powder layer, and is all distributed in fluorescence
On the outer surface of bisque, to which electricity Hong energy can be made instantly available when fluorescent tube just starts burning point, mercury vapour is released at once,
With the instantaneous raising of mercury vapor pressure, light output is rapidly achieved the 80% of stationary value, to substantially improve and shorten time-to-climb.
The present invention uses the yttrium oxide of nano-level sphere powder for raw material, is configured to yttrium oxide dispersion liquid, partly takes
It functions in an acting capacity of the aluminium oxide generally used in the industry and is entrained in the slurry of fluorescent powder, the fluorescence stablized and do not lost powder can not only be prepared
Powder coating, and the photoelectric parameters such as fluorescent tube luminous flux and light efficiency are no less than fluorescent tube of the aluminium oxide as powder, and effect is most apparent
Be then fluorescent tube time-to-climb shortening, time-to-climb only has original 50%.
In conclusion the present invention has the characteristics that not lose powder, fluorescent tube time-to-climb is short.
Specific implementation mode
With reference to embodiment, the invention will be further described.
