[0030] According to another aspect of the present invention, there is provided a method for preparing an anti-corrosion coating, comprising the following steps: S1, mixing the film-forming resin with part of the organic solvent, and stirring to dissolve the film-forming resin; S2, adding the dissolved film-forming resin Add organic corrosion inhibitors and antirust additives to the mixture, add the remaining organic solvent, and stir evenly to obtain anticorrosion coatings. Preferably, part of the organic solvent added in step S1 accounts for 30wt%-50wt% of the total amount of organic solvent. The purpose of adding the organic solvent step by step is to make the film-forming resin dissolve in the organic solvent better, so as to achieve the purpose of its comprehensive dissolution. In the present invention, the film-forming resin is first dissolved in an organic solvent, and the purpose is to obtain a uniformly dispersed film-forming resin. If the dispersion is not uniform, th...

Embodiment 1

[0034] In terms of parts by mass, take 5.79 parts of 210 modified phenolic resin (provided by Zhengli Chemical Co., Ltd.), and add it to 38.66 parts of aromatic solvent oil (provided by Loctite Chemical Co., Ltd., the model is s-100 solvent oil), Stir at a speed of 1500r / min until the above-mentioned modified phenolic resin is completely dissolved.

[0035] To the dissolved modified phenolic resin, add 11.21 parts of ZTH-D1821 dialkyl quaternary ammonium salt (provided by Zibo Tenghui Oil Chemical Co., Ltd.) and 25.76 parts of high-efficiency anti-rust grease (provided by Wuxi Feitian Oil Co., Ltd. ), stirred at a speed of 2000r / min for 2 hours, then added 38.66 parts of organic solvent n-butanol, stirred evenly, and obtained a temporary protective anti-corrosion coating.

Embodiment 2

[0037] In terms of parts by mass, take 1.52 parts of JY14-60 styrene-modified alkyd resin (provided by Dongguan Junyi Chemical Technology Co., Ltd.), and add it to 14.6 parts of organic solvent n-butanol. Stir at high speed until the above-mentioned modified alkyd resin is completely dissolved.

[0038] In the dissolved resin, add 8 parts of organic corrosion inhibitor ZTH-D1821 dialkyl quaternary ammonium salt (provided by Zibo Tenghui Oil Chemical Co., Ltd.), 1.6 parts of carboxymethyl amphoteric imidazoline (provided by Suizhou Tianfeng Chemical Technology Co., Ltd.) and 2.97 parts of pentasodium ethylenediamine tetramethylene phosphate (provided by Shandong Taihe Water Treatment Co., Ltd.) and 15 parts of complex soap-based grease (Great Wall 7013 grease, provided by Yunfeng, Taicang City Provided by Lubricating Oil Co., Ltd.), stirred at a speed of 2000r / min for 2 hours, added 34.07 parts of organic solvent n-butanol, stirred evenly, and obtained a temporary protective an...

Abstract

The invention discloses anticorrosive paint, a preparation method of the anticorrosive paint and an oil tube coated with the anticorrosive paint. The anticorrosive paint comprises raw materials in parts by mass as follows: 0.26-10.31 parts of film-forming resin, 0.48-19.57 parts of an organic corrosion inhibitor, 1.54-35.63 parts of an antirust additive and 30.63-98.94 parts of an organic solvent. The antirust and anticorrosive paint which is low in cost and good in storage stability and has low possibility of sedimentation or layering is obtained through selection of raw materials of the anticorrosive paint for temporary protection and content of the raw materials; the application property of the anticorrosive paint is good, the anticorrosive paint cannot block a pipeline after used, the removal property is good, and the anticorrosive paint is novel waterproof, weather-proof, non-toxic and environment-friendly protective paint; and besides, the cost performance of the raw materials of the anticorrosive paint is high, and the market competitiveness is high.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an anti-corrosion coating, a preparation method thereof and an oil pipe with an anti-corrosion coating on the surface. Background technique [0002] Temporary protective coating is a coating that can play a temporary protective role during processing and transportation, and is removed after processing and transportation. It has special uses, such as temporary protective coatings applied to mechanically processed products, aircraft During the transportation, loading and unloading, and assembly of many products, such as high-speed railway passenger cars, urban subways, and oil pipes, protect the surface of the product from being scratched and polluted during processing. [0003] Due to the special purpose of temporary protective coatings, its technical requirements are quite different from those of general coatings. First of all, the paint is required to have good remova...
