Description
Technical field
The invention belongs to Industrial Stoves anticorrosion of steel structure field of material technology, and in particular to one kind being mainly used for Industrial Stoves
The acidproof of the preventing corrosion of dew points of the steel constructions such as flue, heat-resisting paint and preparation method thereof.
Background technology
Since the nineties in last century, under the macro-plan of country, the industries such as metallurgy, petrochemical industry, coloured, building materials all obtain
Quick development, Industrial Stoves play an important role in the development of these industries.Coal, liquefaction used in these Industrial Stoves
It is mixed that SO2/SO3, chlorion etc. are formed after the flammabilities such as sulphur, the chlorine contained in gas, natural gas, fuel oil and other fuel combinations
It closes in flue gas.Flue gas can react when temperature is gradually lowered to dew-point temperature during flue flows with the vapor in flue gas
Acid is generated, the steel construction of flue is corroded.At present in the design of liner of industry kiln structure, usually in furnace wall inner surface and anchoring
The root of nail applies one layer of pitch, waterglass, structural fibers or other products to obstruct flue gas and steel construction, prevents dew point corrosion
Generation.But that there are temperature in use is low for these materials, and it is soluble to meet water, and flexibility is poor, easy to crack peels off and corrosion resistance is poor
The shortcomings of.
Zhang Chunyu（CN201210133434.X, a kind of preventing corrosion of dew points coating and its preparation method and application）Utilize second
The inorganic matters such as organic matters and bentonite such as alkene-propylene copolymer, 2- sulfydryl phenylpropyl alcohol thiazoles and aqueous high molecular elasticity base-material are made
Although standby coating elasticity is preferably, mixing, dispersion are needed, by multiple tracks works such as polishing, immersion, heating reaction, stirring, filterings
Sequence, complex process.Tian Qiao, Dong Hongwei, Huang must cutting edges of a knife or a sword etc.（CN201610838781.0, a kind of environmentally friendly one pack system industry are anti-
Rotten coating and preparation method thereof）Although the water-based anticorrosive paint prepared using modified aqueous acrylic acid resin using water-based solvent,
It is environmentally friendly, but need to be made by complicated technique in a stirring kettle, and it is only used for the slight anti-corrosion in metal surface.
Invention content
Goal of the invention：Present invention aims in view of the deficiencies of the prior art, providing, one kind is simple for process, at low cost, answers
It convenient can also construct to different operating modes, resistance to sweep of gases and acidproof, heat-resisting paint preparation method that high-temperature flue gas can be in direct contact.
Another object of the present invention is to provide what is prepared with this method not crack at -45 DEG C ~ 250 DEG C, do not peel off, do not melt
Change and can keep excellent elasticity, resistance to sweep of gases simultaneously can be in direct contact high-temperature flue gas, cope with different operating modes can for take scrape,
Acidproof, the heat-resisting paint of the convenient construction of modes such as rolling or mechanically spraying.
Technical solution：In order to reach foregoing invention purpose, the present invention is specifically achieved like this：It is a kind of acidproof, heat-resisting
The preparation method of coating, using the acid resistance filler of 35 ~ 75wt% and the modified resin of 25 ~ 65wt% as raw material, mechanical agitation is to uniform
Barrelling after color, when construction add 0 ~ 15wt% of raw material polyamide or modified anacardol after stir evenly to get acidproof, heat-resisting
Coating.
Wherein, the acid resistance filler be hard pitch, silica flour, aluminium oxide, bentonite, two kinds or two kinds in graphite with
On mixture.
Wherein, the acid resistance filler grain size≤0.15mm.
Wherein, the modified resin is one or both of modified epoxy silicones, phenol-formaldehyde resin modified mixture.
Wherein, the modified resin uses PMA solvents as diluent.
A kind of acidproof, heat-resisting paint, is mainly used in the preventing corrosion of dew points of the steel constructions such as Industrial Stoves flue.
A kind of acidproof, heat-resisting paint be prepared by above-mentioned any acidproof, heat-resisting paint preparation method it is acidproof,
Heat-resisting paint.
The present invention is disperseed using acid resistance filler and modified epoxy as primary raw material by direct churned mechanically mode,
Stirring to after of the same colour can direct barrelling, when construction, adds after the curing agent of 0 ~ 15wt% stir evenly after can directly apply
Work, Gu it is simple for process, at low cost.The inconvenience such as the more anchoring pieces of body structure surface, more bends are applied when the present invention is due to being directed to practice of construction
The method that can directly take spraying application when at work, primary to spray wet-film thickness i.e. up to 1 ~ 2mm, construction efficiency is high.The present invention
By increasing inorganic acidproof, wear resistant filler content, and by the way of modified resin combination so that coating can be in direct contact height
Warm flue gas.
Advantageous effect：The present invention is simple for process and at low cost compared with traditional technology, prepared acidproof, heat-resisting paint
With excellent acid corrosion-resistant, water resistance, it is mainly used for the preventing corrosion of dew points of the steel constructions such as Industrial Stoves flue, in metal watch
There is excellent adhesive force in face, and excellent elasticity, resistance to flue gas punching are not cracked, do not peel off, not melting and can kept at -45 DEG C ~ 250 DEG C
It brushes and high-temperature flue gas can be in direct contact, coping with different operating modes can scrape, rolls or the modes such as mechanically spraying convenient constructions for taking
Feature.
