Abstract
A kind of thick slurry type of epoxide coal bituminous coating, its priming paint composition and proportioning are: Resins, epoxy 15-30% carbolineum 20-40% red iron oxide 20-40% zinc-chrome yellow 2-15% mixed solvent its coat component of 5-25% and proportioning are: Resins, epoxy 10-35% carbolineum 10-30% coal-tar pitch 10-30% talcum powder 5-20% mica powder 5-20% mixed solvent 5-20% flow agent 1-5% utilizes composition proportion coatings formulated of the present invention, time of drying is short, the physical strength height, sticking power is good, acidproof, alkali, the normal temperature brushing, solidify.Be used for pumping station operation and pipeline not under the stopping transportation situation preservative coat upgrade, mend hinder, mending-leakage.
Description
The invention belongs to the chemical coating technical field, specifically a kind of modification of anti-corrosive paints composition proportion.
For secret reason, the complete open record of pipeline outer wall protective system composition and proportioning seldom.Particularly require normal temperature brushing, ambient cure, data is more not rarely seen aspect pipeline does not upgrade preservative coat or field work in stopping transportation or the pumping station operation.What only can recognize at present is the development of pipeline prospective design research institute of China's oil portion, Shenyang Paint Factory and the cooperation of Lanzhou coating institute of the Ministry of Chemical Industry and the repaired mouth coating (identifying in 1979) produced by Shenyang Paint Factory, this coating composition is an epoxy resin E-44, coal-tar pitch, talcum powder, red iron oxide, zinc-chrome yellow, polymeric amide, mixed solvent (toluene, propyl carbinol etc.).This product is progressive for the existing essence of asphalt anti-corrosion agent that China continues to use for a long time, but still has many shortcomings: the big and benzene class toxicity height of this coating solvent for use amount, and harmful, seriously polluted; Poor by this formulation for coating material coatings formulated bonding force simultaneously; When checking with the 2000V electric spark leak detector, can find that a large amount of pin holes exist, this just stays public many hidden danger for later corrosive pipeline.
At above-mentioned shortcoming, it is strong, corrosion-resistant and excellent electrical insulation capability arranged that purpose of the present invention is developed a kind of bonding force exactly, can be at the pipeline coating of normal temperature brushing under the stopping transportation situation, ambient cure not.
In order to achieve the above object, the present invention takes following measures: this coating divides the priming paint finish paint, still is base with Resins, epoxy, and its consumption is a 15-30(weight) between the %.Select carbolineum Wei Zeng Toughness agent for use, purpose is to improve the plasticity of priming paint, finish paint.It is also cheap that carbolineum is that ideal increases agent, price.The present invention has removed coal-tar pitch in priming paint, increase the proportioning of carbolineum, and dope viscosity is reduced.And in finish paint, add coal-tar pitch, can improve erosion resistance, particularly the microbial corrosion resistance energy.
The present invention increases a kind of composition-mica powder in finish paint, because mica is plate crystal, electrical insulation capability is extremely excellent, adds mica powder in coating, not only low price but also greatly increase physical strength, particularly electrical insulation capability.
The present invention selects for use the composition of mixed solvent to be: toluene, dimethylbenzene, pimelinketone, propyl carbinol.Its by volume proportioning be:
Toluene 40-50%
Dimethylbenzene 25-35%
Pimelinketone 15-25%
Propyl carbinol 2-10%
The optimal volume proportioning is:
Toluene 44.83%
Dimethylbenzene 30.09%
Pimelinketone 20.06%
Propyl carbinol 5.02%
Thereby reduced the serious ratio of benzene class in solvent formula of contaminative, in whole prescription, also reduce simultaneously the content of solvent, solvent only accounts for 10-15% in priming paint, only accounts for 8-13% in finish paint, has reduced many (known technology uses 25-30%) than known technology.
The present invention adopts slaking tung oil to make flow agent, and effect is fine.
In sum, composition of the present invention and proportioning are as follows:
Priming paint (by weight percentage)
Resins, epoxy 15-30
Carbolineum 20-40
Red iron oxide 20-40
Zinc-chrome yellow 2-15
Mixed solvent 5-25
The best proportioning (by weight percentage) of priming paint

Coal-tar pitch 10-30
Talcum powder 5-20
Mica powder 5-20
Mixed solvent 5-20
Flow agent 1-5
(slaking tung oil)
The best proportioning (by weight percentage) of finish paint
Resins, epoxy 26.26
Carbolineum 20.23
Coal-tar pitch 20.23
Talcum powder 10.10
Mica powder 12.31
Mixed solvent 9.67
Flow agent 1.20
(slaking tung oil)
A specific embodiment of the present invention is to make 100 kilograms of priming paint and 100 kilograms of finish paints.Priming paint is made:
27 kilograms of carbolineums are heated in boiling still to 105-110 ℃, stablize half an hour, be extracted in the system Lacquered Tin Plate Can, remain on more than 60 ℃, (toluene: dimethylbenzene: pimelinketone: propyl carbinol is 44.83: 30.09: 20.06: 5.02 volumes) 11.36 kilograms slowly add and constantly stir, and solution is mixed, and add 28.42 kilograms of oxidation iron oxide reds successively with the mixed solvent for preparing in advance, 5.68 kilograms of zinc-chrome yellows constantly stir.With the slow impouring of Resins, epoxy that is warmed up in advance more than 30 ℃, do not stop to stir, up to 26.26 kilograms of Resins, epoxy are added, continue to stir, the suction sand mill, levigate, mill is spared, be up to the standards by viscometer and grindometer, filter tinning, thereby made qualified primer base.Qualified product outward appearance half light that takes on a red color, viscosity 80-150 second (25 ± 1 ℃), fineness＜100 micron.
Finish paint is made:
Carbolineum and coal-tar pitch were by 1: 1 proportioning, i.e. 20.23 kilograms of carbolineums and 20.23 kilograms of coal-tar pitch, join and boil in the still, stir, heat, keep half an hour, be extracted in the system Lacquered Tin Plate Can to 105-110 ℃, add 11.36 kilograms of above-mentioned mixed solvents, stir, add 10.10 kilograms of talcum powder, 12.31 kilograms of mica powders successively, 1.20 kilograms of flow agents.Stir, the Resins, epoxy that will be preheated to 60 ℃ in baking oven slowly adds, and adds while stirring until 26.26 kilograms of Resins, epoxy all to add, and enters sand mill, levigate filtration tinning.
The finished product outward appearance is that black has light, viscosity 80-160 second (25 ± 1 ℃), fineness＜100 micron.During actual the use, selecting polymeric amide for use is solidifying agent, because priming paint contains rust-preventive agent, long storage has deposited phenomenon; With before to fully mix, can regulate viscosity with thinner according to field condition.
Utilize composition proportion coatings formulated of the present invention, time of drying is short, physical strength is high, sticking power is good, acid-and base-resisting, normal temperature brushing, curing, complete unnecessary heating.Operate very easy.
Utilize composition proportion coatings formulated of the present invention through tens apparent no wrinkles of unit this coating of probationary certificate such as Beijing Water Co., Qinhuangdao oil pump station, Fuxin Power Plant, be bright paint film, the long-distance transport in not fragile, with 2000V electric spark leak detector check free of pinholes, the electrical insulation capability excellence is applicable to that fully the temperature difference is big or tide mixes rainy even the ocean is regional.
The present invention can be applicable to the inside and outside not stopping transportation of pumping plant preservative coat and upgrades, mends wound, mending-leakage.Be applicable to that pipeline external walls such as oil transportation, gas transmission, water delivery and town gas, defeated lime-ash are anticorrosion.
