Above-mentioned these prescriptions all are in different ratio preparations basically by 2123,2127 resol, Resins, epoxy, rosin, shellac, stopping composition, industrial spirit, Victoria Green WPB.Because these weldering mud prescriptions do not possess versatility, the have nothing for it but bulb of different varieties of electric light source manufacturer is selected different weldering mud prescriptions for use.In addition, the blending process complexity of above-mentioned prescription.At present, the complete processing complexity of the weldering mud that each bulb manufacturing firm adopts, the cycle is long, should not prolonged preservation (generally be no more than 7 days, refer to " mother liquor "), and also the loose phenomenon of bulb happens occasionally.To above-mentioned materials be passed through to add certain amount of industrial alcohol with the ball milling altar respectively as 2123 resins, shellac, rosin, carry out (the length of time about ball milling 48h, depend on that big more, the ball milling time is long more with blocky 2123 and the size of the fragment smashed with iron hammer of rosin; More little, otherwise then.), make it fully dissolve (this liquid is called mother liquor), because mother liquor can not carry out under vacuum state, so will cause the change in concentration of mother liquor excessive or too small in processing (ball milling) process, that is to say: in the course of processing, because (influenced by ambient temperature, more than 30 ℃, and ethanol self has the moisture absorption in the alcoholic acid volatilization, can increase the water content in the mother liquor, cause mother liquid concentration inaccurate.Cause fried shoulder as too high meeting, reason is the resin concentration height, and to bulb, promptly glass bulb (pipe) produces bigger stress and bursts weldering mud through baking-curing the time, is called fried shoulder.Not enough as the low excessively weldering mud viscosity that makes, cohesive force tails off, and perhaps welds the mud cured strength and does not reach, and can cause the loose head of bulb (pipe) equally.In addition, the various mother liquors of the resin of ball milling, rosin, shellac can not be too much, scrap if too much cause easily, the waste reason is the continuous motion of ball milling altar by ball mill, make a part of ethanol in the altar change gaseous state (ethanol molecule) into, cover a part of ethanol of volatilization rapidly that is opened at the ball milling altar, that is to say, the number of times that the altar lid is opened is many more, evaporable ethanol is just many more, the moisture that the number of times that adds to the air in the altar many more (particularly water ratio is the highest in plum rains season air) mother liquor absorbs is just many more, forms vicious cycle.So mother liquor quality guaranteed period just short (7 days).As very few, need the ball milling number of times just to increase, thereby increased the manufacturing cost of bulb.And most importantly the quality of bulb (referring to the pine head) does not guarantee.
Moreover because the pulverizer high speed rotating makes material softenings such as rosin with the heat that produced of friction that minced, adhesion equipment is so technical barrier such as can not process when smashing for rosin, shellac, 2123, resin.
General lamp copper described in " electric light source manufacturing process " and for example, in the general weldering mud prescription of iron lamp holder, shellac too high levels (reaching 54.05%) is in weldering mud reacts by baking-curing, though can reduce the convergent force (stress) that bulb is produced, make stress obtain mitigation, can not cause fried shoulder, but, shellac too high levels in the weldering mud, after can making the oven dry of weldering mud, can not bear bulb at the working temperature behind the burning-point (bulb more than the 200W), " West Lake " board infrared ray bulb (220V250W) as Hangzhaou Bulb Factory's production, the Resins, epoxy high temperature resistant though (comparatively speaking) in should filling a prescription in addition, but Resins, epoxy can not be by the etoh solvent dissolving in the weldering mud, particularly winter, the Resins, epoxy denseness was big, and it is evenly distributed in weldering mud.Ordinary incandescent lamp does not have rosin with in the weldering mud prescription in the prescription of brass lamp holder for another example, and is mobile poor in the baking-curing reaction, makes the various weldering mud material skewness of weldering mud around lamp holder of baking molding, and local strength does not reach requirement, causes loose head easily yet.And for example " shellac in practical adhesive formulation handbook 493 prescriptions is 17.6%, rosin is 7.5%, because shellac is water funk and water vapour, so after making bulb by the weldering mud of this formulated, can not under the Working environment of humidity, use for a long time and store, otherwise, cause loose head easily, the rosin content in this prescription is too high in addition makes when welding the mud baking, and the too expanded foamed weldering mud that makes becomes too loose, or bulb " mud overflows " and " filling core ", cause bulb quality poor (referring to expect mud intensity and outward appearance).
In addition, luminescent lamp, ordinary incandescent lamp, automobile bubble, mercury lamp, different because of their frit of bulb (glass bulb, glass-tube), in addition, their used lamp base material are different, so the coefficient of expansion is also different, just have different weldering mud prescriptions.
The object of the present invention is to provide a kind of highly versatile, blending process is simple, retention period can reach 6 months welding powder of electro-optic source, can be used for electric light source products such as ordinary incandescent lamp series, luminescent lamp series, autobulb series and high-low pressure mercury lamp with the weldering mud of it and a certain amount of alcohol preparation.
For achieving the above object, the present invention has taked change welding powder component and content, and the component and the content of this welding powder of electro-optic source is respectively (consumption is a weight part):
PF-6076A resol 10-22
Shellac 0.5-3
Rosin 0.7-2.5
Expanded type perlite 0.5-5
Feldspar Powder 10-20
Light calcium carbonate 20-50
Terra alba 20-30
Because above-mentioned welding powder components contents is adjusted, make it possess stronger versatility, so electric light source manufacturer needn't fill a prescription again separately for the bulb of different varieties, both saved operation and time, reduced production cost again.
PF-6076A resol is to metal and nonmetally have a very strong bounding force, and thermotolerance, alkali resistance, insulativity are better, are a kind of good tackiness agent.In welding powder of the present invention, it accounts for 10-22.The resol of selecting for use in the past, as 2123 resol of Jiangsu Province's Tai County Four Modernizations plant produced, free phenol can only accomplish less than 4.5%, and polymerization velocity is 130 " 180 "/150 ℃, therefore the deterioration by oxidation speed of this resin is very fast, is unfavorable for the prolonged preservation of welding powder.For this reason, the present invention uses free phenol less than 3.5%, and polymerization velocity is the resol of 70 " 90 "/150 ℃, the PF-6076A resol of producing as Jinan holy well sea Butterworth chemical industry company limited.This resin is an inorganic dose of modified phenolic resins, it not only has all characteristics (referring to the characteristic in weldering mud) of 2123 resol, and big with the bonding force of metallic glass, plasticity good, it is low to contain free phenol, wear-resisting wiping, temperature tolerance height (with 2123 resins than) the heat decomposition temperature height.It and shellac, rosin, perlite (expanded type), terra alba, Feldspar Powder and pearl filler etc. are optimized that to have the coefficient of expansion after the combination moderate, and temperature tolerance obviously improves (enhancing).By the adjusting of this resin quantity, can satisfy the lamp holder and the bonding requirement of different glass of unlike material.
Shellac is a kind of natural resin, also is a kind of coagulating property material, can make weldering mud have toughness and plasticity during baking, with the situation that is adapted to generally expand with heat and contract with cold, thereby avoids the glass bulb abutting edge to burst, promptly fried shoulder.
Rosin is a kind of incoagulable natural gum, has certain fluidity when weldering mud baking heating, can fill the space of lamp holder and bulb sealing part, makes weldering mud and glass bulb strong bond.
Among the present invention, the content of shellac is 0.5-3, and rosiny content is 0.7-2.8.Shellac and rosiny ratio play crucial effect.Lacked or do not added if rosin adds, when weldering mud baking and curing, can produce bigger stress, caused glass to burst easily lamp body.Will make the intensity of weldering mud not reach requirement if rosin has been added, lamp holder and glass bulb hold can't stand certain torsion moment, thereby loose head occurs.
Expanded type perlite, Feldspar Powder, light calcium carbonate and terra alba as stopping composition should keep dry, alkali-free, and the content in welding powder is moderate.Weighting material bond degree more after a little while can increase, otherwise can descend.The perlitic major ingredient of expanded type is Sio
2, its light specific gravity can increase thermotolerance and intensity in weldering mud.Feldspar Powder is CaAl

8Adopt the structural strength after two kinds of varigrained fillers can improve the baking of weldering mud, the maximum particle size of Feldspar Powder is 0.3mm, and the maximum particle size of lime carbonate is 0.16mm.Terra alba has the adhering and solidifying effect, helps improving the degree of adhesion of weldering mud.
The content of stopping composition is respectively among the present invention, expanded type perlite: 0.5-5, Feldspar Powder: 10-20, light calcium carbonate: 20-50, terra alba: 20-30.
Produce and use the production stage that this welding powder takes elder generation's batching to pulverize again for convenient.Be to prolong preservation period, welding powder can adopt vacuum packaging, with contacting of isolated welding powder and outside air.Only need during use weldering is mixed powder.Industrial spirit and indicator, stirring gets final product as malachite green.
Because the weldering mud according to above-mentioned welding powder preparation has characteristics such as the coefficient of expansion is moderate, the obvious enhancing of temperature tolerance, therefore, can be used for the bonding of multiple lamp holder and glass bulb.
