Abstract

Be coated with the electric light of light absorbing zone (7), described absorbed layer (7) is partly to be arranged on the electric light shell (1), and comprises the manganese dioxide (MnO as colouring agent 2), magnesium oxide and titanium dioxide, they all are included in and contain in the silicon adhesive.

Description

Be coated with the electric light of light absorbing zone
The present invention relates to the electric light that its housing parts is laid with a light-absorbing coating, this coating is included in iron oxide and the manganese dioxide as colouring agent that contains in the silicon adhesive to be contained.This contains silicon adhesive and generally includes a kind of organo-silicon compound, and when heating, this silicon compound just is converted to silicon dioxide.So this silicon dioxide just is used as a kind of beading thing of bonding described colouring agent.
With regard to various electric lights, the light-absorbing coating on the lamp housing is commonly used to cover part emission light.Therefore this lamp housing is a shadowed layer.This class electric light (for example) has the halogen incandescent lamp as the car lighting lamp, or high-pressure discharge lamp; The latter's configurable one outside lamp housing.Described light-absorbing coating can be coated on outside or the interior lamp housing.Because this type of electric light will bear high heat, so their shell contains hard glass or quartz glass usually.Described light-absorbing coating should be able to be corrosion-resistant, can bond to described lamp housing and the anti-zoned trace of energy securely.
By this class known lamp that the No.1422491 British patent is learnt, described colouring agent comprises iron oxide, cobalt oxide and manganese dioxide.People in a short time from then on consider with cobalt oxide (COO), yet because it has been not suitable for being used for the electric light coating for the carcinogen event.
The electric light of being learnt by British patent 1334329 has same shortcoming, and its shell coating comprises as the cobalt oxide of colouring agent and carbonyl iron.
In the electric light according to No1909394 Germany patent, it is pigment coated to be provided with the silester that contains as the silicon of mineral black.This pigment can only make with the sizable technology of difficulty, and too transparent consequently bright inadequately.
The light-absorbing coating that electric light had that discloses by No. 2837280 prospectus in Germany comprises carbonyl iron and silica flour and does not have siliceous adhesive.This coating is fired under 530 ℃ of high temperature and is formed.Yet have now found that: this pigment can only be used for certain several shells top shape and can only use a kind of impregnation technology of complexity.
Therefore, the objective of the invention is for a kind of electric light with a kind of like this light-absorbing coating is provided, this coating can form and bonding good with simple technology mode, and this coating is enough to shading and without cobalt oxide.
According to the present invention, promptly can reach above purpose, because described coating contains the titanium dioxide as additional colorant by the described the sort of electric light of this paper section of beginning.
The inventor is surprised to find that: can show the opacity of improving this coating by adding this titanium dioxide as white.
According to another embodiment of the present invention, described colouring agent can be present in the starting mixt of following column weight amount proportioning:
Magnetic iron ore (FeO, Fe 2O 3) 14 to 20%
Manganese dioxide 8 to 16%
Carbonyl iron 14 to 21%
Titanium dioxide 5 to 12%
In one embodiment of the invention, starting mixt comprises the silester as adhesive, therefore obtains firm adhesive coatings.
One embodiment of the present of invention are now more fully described with reference to the accompanying drawings.
This illustrates the end view as the halogen incandescent lamp of car lighting lamp.
The halogen incandescent lamp of a 12V 55W is as a kind of parabolic reflector of car lighting lamp.This lamp has the shell 1 of a quartz or hard glass system.Be provided with two helical heaters 2 and 3 in this shell 1, wherein main filament 2 is placed in the focus of parabolic reflector, and inclination filament 3 is partly centered on by a sloping baffle 4.Housing 1 is filled with a kind of inert gas and a kind of halogen compounds, so that this lamp can obtain a tungsten halogen cycle (tungston-halogen circulation) during operation.Lamp housing 1 places on the base 5 that has flange connector 6.
The top 7 that has the lamp housing 1 of evacuation tube seal head 8 is placed on the lateral surface that is covered with light-absorbing coating 9.This coating comprises magnetic iron ore, manganese dioxide, carbonyl iron and the titanium dioxide as colouring agent, and these colouring agents all are included in a kind of containing in the silicon adhesive.Coating 9 can comprise following starting mixt:
The amount material
430 gram titanium dioxide
690 grams, four manganese oxide
70 gram sodium metaphosphates
1900 milliliters of ethyl silicate aqueous solution
150 milliliter of one fourth fat glycol ether
80 milliliters of ethylene glycol
500 milliliter of 96% denatured ethyl alcohol
930 gram carbonyl iron EN8
(Bay ferrox Bayer synthesizes oxygen to 900 gram magnetic iron ores
Changing Inland Steel produces)
These all substances with about 3kg of frangible sphere of 13mm diameter are sent into one 51 type porcelain ball mill (51 porcelain ball mill) together also ground 18 hours on the pressure roller with per minute 16 commentaries on classics rotations within it.Then, allowing the mixture worn into have by one widely sieves for the woven wire of 0.1mm mesh.So this mixture is just available at any time.
The top 7 of lamp housing 1 is immersed in this mixture, makes it dry and through heat-treated then, that is, the shell of coating 7 heats in a drying oven, is added to the 12V voltage source simultaneously and makes their work on these lamps.Then, utilize ring-type blowtorch (ring burners) to be heated under certain temperature of (＞1000 ℃) at the top 7 of melanism, make them be the red heat attitude with oxidizing flame.During such heat treatment, ethyl silicate is changed into iron oxide and is burnt so that described coating is glued fast to shell within it.The thickness of this coating 9 is about 0.005mm.
The transparence value that the electric light of making thus is covered with the top of black coating almost is equivalent to the resulting result of a large amount of pigment of its twice dipping.
