Description
Technical field：
The present invention relates to anti-corrosion powder body materials in a kind of steel pipe, belong to a kind of long-acting negative oxygen of anti-corrosion in steel pipe and resist
Bacterium anti-corrosive powder paint.
Background technology：
There is a large amount of bacterium and alga microbials, such as sulfuric acid in city discharge pipe network, oil extraction in oil field, filling pipe
The presence and continuous breeding of salt reducing bacteria, iron bacteria, saprophytic bacteria in inner wall of the pipe, make inner wall of the pipe accumulate dross, corrode and stifled
Fill in pipeline；There is the water quality for directly affecting water supply in harmful bacteria and alga microbial.
Invention content：
The present invention is conveyed in liquid for city discharge pipe network, oilfield oil pipeline and waterflood-transmission line since harmful microorganism is deposited
Attached wall breeds dross plugging, seriously hinders the normal production capacity in oil field；Harmful microorganism and algae deposits in urban water supply
, it is serious to affect the situation of water quality, and provide anti-corrosion in a kind of steel pipe long-acting negative oxygen Antimicrobial preservative powdery paints.Make
Antirust coating in pipeline is done with long-acting negative oxygen antibacterial ring anti-corrosive powder paint electrostatic spraying, not only favorable anti-corrosion effect, and can be straight
It connects and kills harmful bacteria and alga microbial, prevent harmful bacteria, the corrosion of alga microbial and the breeding dross plugging of attached wall.And
Negative oxygen ion is can release, can purify water for feed pipe, water is made to become negative oxygen ion water.
The technical solution adopted in the present invention：The long-acting negative oxygen Antimicrobial preservative powdery paints of anti-corrosion is by following original in steel pipe
Material is made, and following ingredients are by weight ratio：35~45 parts of epoxy resin, 15~25 parts of acrylic resin, phenolic aldehyde Type of Collective
9~13 parts of object curing agent, 6~9 parts of levelling agent polyacrylate analog copolymer, wetting agent Polymers 2.~
4 parts, 0.3~0.5 part of co-catalyst 2-methylimidazole, 5~10 parts of titanium dioxide, granularity is ± 2000 mesh tourmaline powder 0.5 of 800 mesh
~3 parts, 2.0~3.5 parts of oxygen core liquid, granularity is 9~15 parts of ± 20 mesh concave convex rod of 200 mesh, and 3~15 parts of negative ion powder, function is filled out
Expect 28~35 parts of wollastonite in powder or mica powder, 0.5~0.8 part of pore eliminator styrax, 1~2.5 part of pigment.
Copolymer of the levelling agent for butyl acrylate and ethyl ester etc. in said program；Wetting agent is methyl methacrylate
With the copolymer of butyl ester.Oxygen core liquid is purchased from Beijing An Jiebao developments in science and technology Co., Ltd.Negative ion powder is purchased from the prosperous Wei ore deposits in Lingshou County
Produce Co., Ltd.
The preparation method of the long-acting negative oxygen Antimicrobial preservative powdery paints of anti-corrosion is in the steel pipe：By above-mentioned raw material
2900r/min mixed at high speed powdering objects are carried out, then melted under the conditions of 96 DEG C ± 3 DEG C by double screw extruder according to proportioning
Reactive extrursion glues colloid, is rolled into thick 1.5mm continuous sheet, and air-cooled hardening crosses wolf's fang roll-in and fragmentates, then ground by high speed
Powder machine wears into granularity as ± 20 mesh powder of 160 mesh, selectes granularity through sub-sieve and obtains long-acting negative oxygen Antimicrobial preservative powdery paints；
Through electrostatic spraying, melting and solidification forms the long-acting negative oxygen of 150 μm~300 μ m thicks under inner surface of pipeline, 230 DEG C of temperature conditions
Antimicrobial preservative coating.
Advantageous effect possessed by the present invention：It is done in pipeline and prevented using long-acting negative oxygen Antimicrobial preservative powdery paints electrostatic spraying
Rotten coating, not only favorable anti-corrosion effect, and can directly kill harmful bacteria and alga microbial prevent harmful bacteria, algae micro-
The corrosion of biology and the breeding dross plugging of attached wall, and negative oxygen ion is can release, it can purify water for feed pipe, become water
Negative oxygen ion water.
Due to adding preferred negative ion powder in " long-acting negative oxygen Antimicrobial preservative powdery paints ", it can uniformly be distributed
In powdery paints, after the curing of electrostatic spraying high-temperature fusion, at each position of coating with the presence of antiseptic, when thin
After the harmful microorganisms such as bacterium, mould, algae contact antimicrobial coating, antimicrobial component therein attack bacteria quickly punctures bacterium
Cell membrane, the enzyme of attack cell after anion is combined with bacterium, make bacterium generate the change of structure or the transfer of energy, upset
The eupnea system of bacterium causes its death, achievees the purpose that killing, and itself nonhazardous；Killing the same of harmful bacteria
When seldom consume oneself, also do not influenced by time, illumination, moisture, as long as corrosion-inhibiting coating exists, antibacterial functions would not lose
It loses, so such " long-acting negative oxygen Antimicrobial preservative powdery paints " coating has long acting antibiotic effect, it is micro- to bacterium, mould, algae
Biology has good killing function, contacts sterilization rate >=95%.The application is simultaneously added to natural oxygen core liquid, can discharge for a long time negative
Oxonium ion purifies water.Furthermore this corrosion-inhibiting coating adhesive force is good, and surfacing is smooth, and incrustation scale class substance is difficult to retain, moreover it is possible to
Play the role of antiscale drag reduction, compared with not making corrosion-resistant steel pipe, liquid-conveying amount can improve more than 5%, be ideal steel
Pipeline internal corrosion coating, long-term antibacterial can not only be played the role of, but also it is defeated to reduce pipeline by doing pipeline internal corrosion using it
It is pressurization pressure, energy saving, reduce many unnecessary producing costs.
Specific embodiment：
Below in conjunction with example, the invention will be further described：The long-acting negative oxygen Antimicrobial preservative powder of anti-corrosion in the steel pipe
Last coating, is made by following raw materials according, and following ingredients are by weight ratio：35~45 parts of epoxy resin, acrylic resin 15~
25 parts, 9~13 parts of phenolic polymer curing agents, 6~9 parts of levelling agent polyacrylate analog copolymer, wetting agent metering system
2.~4 parts of acid esters analog copolymer, 0.3~0.5 part of co-catalyst 2-methylimidazole, 5~10 parts of titanium dioxide, granularity for 800 mesh ±
2000 0.5~3 part of mesh tourmaline powders, 2.0~3.5 parts of oxygen core liquid, granularity be 9~15 parts of ± 20 mesh concave convex rod of 200 mesh, anion
