Description
Technical field
The invention belongs to steel bonding glue technical fields, and in particular to a kind of steel bonding glue and its system for economizer steel bonding
Preparation Method.
Background technique
Economizer (English name Economizer) be mounted to boiler back end ductwork lower part for recycle discharged fume it is remaining
Boiler feedwater, is heated into the heating surface of the saturated water under drum pressure by a kind of device of heat, since it absorbs high-temperature flue gas
Heat reduces the exhaust gas temperature of flue gas, saves the energy, improve efficiency, is widely used in industrial processes, with into
The effects of row heat recovery.
Existing economizer is to produce by welding, and during the welding process, inevitably can be to economizer tube wall
Pad at generate damage, after leading to long-time use, coiled pipe leads to the problem of leakage, brings security risk to production.
And existing steel bonding glue it is most of be all applied under normal temperature state structural steel bonding or concrete it
Between bonding, and economizer is due to the difference of its working environment, does not require nothing more than steel bonding glue with high temperature resistance, need to also be in high temperature
There is down excellent adhesive property and toughness, existing steel bonding glue obviously can not be suitable under hot environment as a result,
In economizer.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provide it is a kind of for economizer steel bonding steel bonding glue and its
Preparation method can effectively solve existing steel bonding gluing relay deficiency, the problem of high temperature resistance difference.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is:
A kind of steel bonding glue for economizer steel bonding, comprises the following components in parts by weight:
50~60 parts of polyimides, 70~80 parts of epoxy resin, 50~60 parts of isopropyl acetate, 20~30 parts of siloxanes,

And 5 parts of antioxidant.
Further, coupling agent is silane resin acceptor kh-550, cumyl hydroperoxide, Aluminate or ethylene-acrylic acid
Methyl esters.
Further, toughener is carboxyl liquid nitrile rubber, carboxyl-terminated liguid nitrile rubber, polysulfide rubber, liquid silicon
Rubber, polyethers or polysulfones.
Further, antioxidant be antioxidant 1076, antioxidant 168, antioxidant 164, antioxidant TNP,
Antioxidant CA or antioxidant DLTP.
Further, reaction temperature is 135 DEG C in step (1).
Further, reaction temperature is 150 DEG C in step (2).
The preparation method of above-mentioned steel bonding glue, comprising the following steps:
(1) epoxy resin and nano silica are stirred by formula, form mixed liquor A；Then by isopropyl acetate
Ester and siloxanes mixing, form mixed liquid B；Mixed liquor A and mixed liquid B are stirred in 120~150 DEG C, are then added even
The different heptonitrile of nitrogen two, continues to be stirred to react 3~5h；
(2) polyimides, glycerol, carbolic oil, antioxidant and toughener are mixed, step (1) products therefrom is then added
In, double hydroxyphthalimides and coupling agent, which are added, in 100~150 DEG C of 5~10h of reaction obtains steel bonding glue.
The invention has the benefit that
1, during preparing the steel bonding glue, epoxy resin be tentatively modified by nano silica, can be had
The temperature tolerance of the promotion epoxy resin of effect, toughness；Then on this basis, using azobisisoheptonitrile as initiator, by connecing
Silicon-containing group is imported the positions such as main chain, the side chain of epoxy molecule by branch copolymerization technique, contains epoxy molecule fire-retardant
Ingredient, make its except possess fire-retardant, high heat resistance, it is anti-oxidant, nonflammable the features such as in addition to, moisture-proof also with higher and strand
Flexibility, good high-temperature resistant result can not only be reached, also will not influence the mobility of steel bonding glue entirety.
2, by the effect of double hydroxyphthalimides and coupling agent, make the epoxy of polyimides Yu modified processing
Resin-bonded together, since double hydroxyphthalimides contain N-OH, is easy production free radical, can effectively be catalyzed poly-
Connection between acid imide and epoxy resin；Meanwhile double hydroxyphthalimides can also be produced with the hydroxyl in epoxy resin
Raw ring-opening reaction, further promotes the connection of polyimides and epoxy resin, imparts the excellent heat resistance of epoxy resin
Energy and toughness；And the epoxy resin after polyimides connects, also there is excellent adhesive property, promote the viscous of whole steel bonding glue
Relay.
3, after polyimides is in conjunction with the epoxy resin of modified processing, cooperate antioxidant, so that steel bonding glue has
Excellent high temperature resistance, meanwhile, under high temperature environment, the epoxy resin of modified processing can form one layer of charcoal on surface
Layer prevents material further by high-temperature oxydation, to protect adhesive effect and steel bonding glue sheet itself.
4, by the way that toughener is added, the bonding force of steel bonding glue entirety can further be enhanced, and can guarantee its toughness, together
When, under the action of glycerol, moreover it is possible to enhance its mobility；And carbolic oil has mobile faintly acid corrosive nature, it can be to steel
Surface generates certain corrosion, promotes the bonding force between steel bonding glue and steel.
