Abstract
The present invention relates to one kind of anticorrosive paint for thick oil condensing heat exchanger and its production process. The anticorrosive paint is produced through adding butanol etherified phenolic resin and modified epoxy resin into the mixed solvent comprising xylene, diacetone alcohol, cyclohexanone and diabasic carboxylic ester; adding polymethylalkyl siloxane solution, gamma-methyl acryloyloxy propyl trimethoxyl silane solution and polyether modified silicone solution and mixing; adding titania, precipited barium sulfate, grey ferrotitanium powder, gaseous silica and 1250 mesh wollastonite powder and mixing; and grinding to form the paint. It is coated to the inner wall of high temperature raw oil heat exchanger to form anticorrosive coating.
Description
Technical field
The present invention relates to anticorrosive paint for condensed thick oil heat exchanger and manufacture method, be used for super viscous crude field high temperature crude oil condensing heat exchanger tubulation tube bank protection against corrosion.
Background technology
The super viscous crude field of existing part utilizes 23 ℃～24 ℃ oil field extracted waters by interchanger 170 ℃～180 ℃ super viscous crude of extraction to be cooled to 80 ℃～90 ℃, manages defeated again.Because recovered water corrodibility is strong, cause the tube bank of simple steel heat exchanger to use two months with regard to corrosion failure.High temperature crude oil condensing heat exchanger coil pipe outer wall anti-corrosion, the way of employing has: adopt the stainless steel tube bank, tube bank outer wall nickel phosphor plating, aluminising etc.But have following shortcoming: the stainless steel tube bank uses two first quarter moons with regard to corrosion failure; The nickel phosphor plating tube bank is used and serious corrosion pit just occurred in 3 months, the tube bank of wall thickness 2.5mm, and the only surplus 0.3mm that some places are corroded might bore a hole at any time; The aluminising tube bank is used and was also occurred serious corrosion in 1 year 0 40 days.

More excellent anticorrosive paint for condensed thick oil heat exchanger, it is characterized in that by 1 weight part modified epoxy, 0.25 the resol of weight part butanol etherification, 0.25 weight part dimethylbenzene, 0.12 weight part diacetone alcohol, 0.12 weight part pimelinketone, 0.12 weight part carboxylic acid dibasic ester, 0.05 weight part gathers methyl alkyl siloxane solution, 0.0125 weight part γ-methacryloxypropyl trimethoxy silane solution, 0.05 the silicone solution that weight part is polyether-modified, 0.17 parts by weight of titanium dioxide, 0.17 weight part process white, 0.33 weight part grey ferrotitanium powder, 0.0125 weight part aerosil, 0.375 weight part 1250 order wollastonite powder are formed, high bake solidify to form erosion shield during use.
The manufacture method of anticorrosive paint for condensed thick oil heat exchanger, it is characterized in that the resol of 1 weight part modified epoxy and 0.20～0.3 weight part butanol etherification is joined 0.15～0.3 weight part dimethylbenzene, 0.1～0.2 weight part diacetone alcohol, 0.1～0.2 weight part pimelinketone, 0.1 in the mixed solvent of～0.2 weight part carboxylic acid dibasic ester, dispersing and dissolving in addition, after the high-speed stirring, under condition of stirring, add the poly-methyl alkyl siloxane solution of 0.01～0.1 weight part, 0.01～0.1 weight part γ-methacryloxypropyl trimethoxy silane solution, 0.01 the silicone solution that～0.05 weight part is polyether-modified, after being uniformly dispersed, under condition of stirring, add 0.1～0.2 parts by weight of titanium dioxide successively, 0.1～0.3 weight part process white, 0.1～0.5 weight part grey ferrotitanium powder, 0.01～0.05 weight part aerosil, 0.1～0.5 weight part 1250 order wollastonite powder, after being uniformly dispersed, grind 1.0～1.5h with sand mill then and make, high bake formation erosion shield behind applying coating during use.
The manufacture method of more excellent anticorrosive paint for condensed thick oil heat exchanger, it is characterized in that the resol of 1 weight part modified epoxy and 0.25 weight part butanol etherification is joined 0.25 weight part dimethylbenzene, 0.12 weight part diacetone alcohol, 0.12 weight part pimelinketone, 0.12 in the mixed solvent of weight part carboxylic acid dibasic ester, dispersing and dissolving in addition, after the high-speed stirring, under condition of stirring, add the poly-methyl alkyl siloxane solution of 0.05 weight part, 0.0125 weight part γ-methacryloxypropyl trimethoxy silane solution, 0.05 the silicone solution that weight part is polyether-modified, after being uniformly dispersed, under condition of stirring, add 0.17 parts by weight of titanium dioxide successively, 0.17 weight part process white, 0.33 weight part grey ferrotitanium powder, 0.0125 weight part aerosil, 0.37.5 weight part 1250 order wollastonite powder, after being uniformly dispersed, grind 1.0～1.5h with sand mill then and make, high bake formation erosion shield behind applying coating during use.
Anticorrosive paint for condensed thick oil heat exchanger of the present invention and manufacture method by the phenol resin solution and the modified epoxy solution of butanol etherification, add that the corrosion-and high-temp-resistant color stuffing of a spot of auxiliary agent and some amount is formulated.In the modified epoxy molecular structure that in manufacturing processed, uses groups such as a large amount of hydroxyls, phenyl ring are arranged, active epoxy group(ing) can form very firm chemical bond with the interface metal atomic reaction in solidification process, strengthened the sticking power of coating and base material, and made that coating is hard, snappiness good.Hydroxyl in the structure directly links to each other with phenyl ring, because the conjugative effect of phenyl ring, make on the hydroxyl the total electron pair of Sauerstoffatom shift to phenyl ring, hydrogen atom very easily forms the ion of unbound state, when with etchant solution in the corrosion atom when it's convenient produced common-ion effcet mutually, hindered in the resin structure the free of hydrogen atom on the hydroxyl.Thereby has an excellent acid corrosive nature.Do not contain in the pigment and can have been reduced the transmitance of corrosion thing by the active metal element of acid and alkali corrosion at coatingsurface.The γ that uses-methacryloxypropyl trimethoxy silane solution improves levelling property and gloss, produces the long wave effect, and prevents the shrinkage cavity of system.Poly-methyl alkyl siloxane solution and polyether-modified silicone solution reduce the surface tension of coating system, have improved to flow and levelling property and help to eliminate bubble in the coating, and have avoided the formation of Bei Nade whirlpool.
The present invention's beneficial effect compared with prior art
