Problems solved by technology

Domestic research on rust-resistant anti-corrosion coatings started earlier, but it can be directly coated underwater or on oil, and has multi-functional long-term effects such as transformation, penetration, stability, shielding and weather resistance, heat and humidity resistance, wear resistance, and electrochemical protection. Anti-corrosion coatings, there is no official product and related production process in China at present

preparation example Construction

[0039] The preparation process of the metal anti-corrosion coating is as follows: put 5.0-10.0% of the total weight of the modified polymer organic compound coal tar pitch selected from the coating base material 1 into the mixing tank, start stirring, and add 24.5% of the total weight ~33.0% of one of the paint base materials 2, after stirring for 30~60 minutes, add active rust inhibitor 3 accounting for 12.0~19.0% of the total weight, active rust inhibitor 4 accounting for 12.5~20.0% of the total weight, accounting for the total 3.0-6.0% active antirust agent 4 by weight, then add high-performance dispersant TA-100-50 accounting for 5.0% of the total weight, stir for 100-150 minutes to make a slurry, and send the slurry into a sand mill to grind for 100 After ~120 minutes, add a mixed solvent accounting for 12.5-17.5% of the total weight, adjust the viscosity, stir for 30 minutes as component A of the metal anti-corrosion coating, and pack it in a barrel. Use curing agent suc...

Embodiment 1

[0042] Add 10% of the modified macromolecule organic compound coal tar pitch into the mixing tank, start stirring, then add 24.5% of the total weight of fluororubber modified epoxy acrylic resin, stir at a low speed for 40min, and then add the 12% zinc-aluminum alloy powder by total weight, 20% micaceous iron oxide and iron-titanium powder (wherein micaceous iron oxide: iron-titanium powder=1:1), 6% titanium nanopolymer and coal by total weight Based polyaniline (where titanium nanopolymer: coal-based polyaniline = 0.3: 5.7), then add 5% of the total weight of the dispersant TA-100-50, high-speed stirring for 100min to become a slurry, and then put the slurry into the sand After grinding in the mill for 110 minutes, add 12.5% ​​of the total weight of mixed solvent to adjust the viscosity, and then stir for 30 minutes. After uniformity, it will become the first component of the coating, and it will be packed in barrels for later use. The curing agent is component B, packed in b...

Embodiment 2

[0044] Add 5% of the modified polymer organic compound coal tar pitch into the mixing tank, start stirring, then add 33% of the total weight of fluororesin-modified polyurethane acrylic resin, and stir at a low speed for 60 minutes. Then add successively zinc-aluminum alloy powder accounting for 19% of the total weight, mica iron oxide and iron-titanium powder accounting for 12.5% ​​of the total weight (wherein mica iron oxide: iron-titanium powder=1:1), accounting for 3% of the total weight of titanium nano Polymer and coal-based polyaniline (wherein titanium nanometer polymer: coal-based polyaniline=1: 2), then add the dispersant TA-100-50 accounting for 5% of the total weight, stir at high speed for 150min to become a slurry, and then put the Put the slurry into a sand mill and grind it for 100 minutes, then add 17.5% of the mixed solvent by weight to adjust the viscosity, and stir for another 30 minutes. After being uniform, it will become the first component of the coating...

Abstract

The invention discloses long-acting metal anticorrosive paint used in metal member and equipment and preparing method, which is made by stirring and grinding coal tar pitch, organic polymolecularity resin, antirusting agent and auxiliary agent and then adding curing agent after adjusting viscosity. The metal anticorrosive paint possesses good weatherability and corrosion resistance, and can be used in metal member, metal member, building, underground engineering, ship and other preservative engineering.

Description

technical field [0001] The present invention relates to a coating and a manufacturing process, in particular to a novel multifunctional long-lasting metal anti-corrosion coating and its manufacturing process applied to metal structural parts or metal equipment, belonging to the category of CO9D195 / 00 or C09D5 / 08 . Background technique [0002] Metal corrosion is a natural phenomenon that pervades all fields of national economic construction. It devours a large amount of non-renewable precious resources on the earth every moment, and seriously restricts the development of the national economy. [0003] According to domestic and foreign surveys, the loss caused by corrosion accounts for about 3-4% of the gross national product. The results of the corrosion survey released by the United States last year showed that the average annual direct economic loss is as high as 276 billion US dollars. The global economic loss caused by corrosion last year was about 1.2 trillion US doll...
