Description
Technical field
The present invention relates to the manufacturing technology of power saving fluorescent lampss, particularly to a kind of internally coated preparation method of fluorescent tube.
Background technology
In general, present home-use electricity-saving lamp low-pressure gaseous discharge lamp, relies primarily on mercury vapor discharge and produces ultraviolet
Line deexcitation phosphor powder layer sends visible ray and is used for illuminating.
Hydrargyrum is a kind of noxious substance, its in the production link of electricity-saving lamp and after scrapping all can because volatilize hydrargyrum and to ring
Border pollutes, and gives people body and environment brings harm, and wherein, European Union just requires every electricity-saving lamp in forcing ROHS instruction
The mercury content of pipe must be smaller than 5.But in actual production process, hydrargyrum can be decayed due to the use of fluorescent tube, leads to it
Actual addition is often greater than theoretical amount, and such waste fluorescent lamp easily will result in very big pollution.
In addition, this fluorescent lamp is after a long time use, its brightness of illumination can be gradually lowered, and often increases fluorescent tube quantity
To improve brightness, to increased energy resource consumption.
Content of the invention
It is an object of the invention to provide a kind of internally coated preparation method of fluorescent tube, the consumption of hydrargyrum can be reduced, subtract
The decline of few brightness.
The present invention is realized by following measures
The invention discloses a kind of internally coated preparation method of fluorescent tube is it is characterised in that adopt following steps:
（1）Prepare composite phosphor:Take the carbon nanometer that 10 weight portions a diameter of 20-50 nm, length are 10-30 micron
Pipe, is added in the water of 200-300 weight portion, is uniformly mixed under Ultrasonic Conditions, add the fluorescence of 20 weight portions
Powder, the levelling agent of 1 weight portion, the defoamer of 0.2 weight portion, the ethylene glycol monobutyl ether of 0.5 weight portion, stir, add
The water-borne acrylic resin of 20 weight portions, stirs, standby；
（2）Utilize film applicator to coat one layer of aluminium oxide in the inner surface of tube, fluorescent tube is placed in tube-baking machine, is heated to 200-
300 DEG C, heat 10-20min, form the pellumina that thickness is 400-500 μm；
（3）By step（2）Fluorescent tube be coated with one layer of composite fluorescence bisque, fluorescent tube is placed in tube-baking machine, is heated to
500-600 DEG C, heat 20-30min, form the fluorescent powder membrane that thickness is 200-300 μm.
CNT is as monodimension nanometer material, lightweight, and hexagonal structure connects perfection, has the power of many exceptions
, electricity and chemical property.CNT is that one kind has special construction（Radial dimension is nanometer scale, and axial dimension is micro-
Rice magnitude, pipe two ends are substantially all sealing）One-dimensional Quantum material.CNT is mainly by the carbon atom of hexagonal arrangement
Constitute several layers to tens of layers of coaxial pipe.Keep fixing distance, about 0.34nm, diameter generally 2 ~ 20 between layers
nm.
The composite coating of the present invention, adds a certain amount of CNT, due to having a number of active electricity in its pipe
Son, can supplement the electronics of loss during mercury vapor discharge, reduce the consumption of mercury vapour, keep stablizing of mercury vapour.Meanwhile,
Due to stablizing of mercury vapour, light in fluorescent tube can be made to protect long-term stablizing, reduce the optical attenuation of fluorescent tube.
The fluorescent tube made by said method, 500 hours hydrargyrum consumptions below 1%, 500 hours light decay down control
Within 2%.
Specific embodiment
Give an actual example below and describe the present invention.
Prepare composite phosphor:Take the CNT that 10 weight portions a diameter of 20-50 nm, length are 10-30 micron, plus
Enter in the water of 250 weight portions, be uniformly mixed under Ultrasonic Conditions, add fluorescent material, 1 weight portion of 20 weight portions
Levelling agent, the defoamer of 0.2 weight portion, the ethylene glycol monobutyl ether of 0.5 weight portion, stir, add 20 weight portions
Water-borne acrylic resin, stirs, standby.
Using bench, lamp tube elongation is formed fluorescent tube.
Utilize film applicator to coat one layer of pellumina in the inner surface of tube after pipe machine-shaping, fluorescent tube is placed in tube-baking machine
In, it is heated to 250 DEG C, heat 15min, form the pellumina that thickness is 450 μm.
Then, it is coated with one layer of composite fluorescence bisque, fluorescent tube is placed in tube-baking machine, be heated to 550 DEG C, heat 25min,
Form the fluorescent powder membrane that thickness is 250 μm.
Fluorescent tube is placed in tube-baking machine, adjusts baking temperature and be divided into five areas, five subregions be respectively 300 DEG C, 500 DEG C,
900 DEG C, 600 DEG C and 400 DEG C.
Filament is installed in fluorescent tube, filament adopts long-life alloy tungsten filament as filament, and needs before installing filament
Last layer silicon nitride coating to be plated on filament, coating layer thickness is 20 μm.
By rare gas and the mercury seal that is used for being produced ultraviolet by electric discharge is contained in a U-shaped slow release groove, slow release
Groove end face opening and in opening overlay film, this film decomposes after powered up, mercury vapour is atomized and is full of fluorescent tube space.
Fluorescent tube is exhausted, to form tubing vacuum, reduces the consumption to hydrargyrum for the tube load.
Using the fluorescent tube of said method preparation, power is divided into 5W, 20W, 40W, 80W.
Using same method, prepare common fluorescent tube, power is divided into 5W, 20W, 40W, 80W, differ only in compound glimmering
CNT is not contained in light powder.
Test it at 500 hours, the test data of hydrargyrum consumption is shown in Table 1, and the test data of light decay rate is shown in Table 2.
