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

[0038] The preparation process of the metal anti-corrosion coating is as follows: put the coating base material 1 (such as modified macromolecular organic compound coal tar pitch) accounting for 5.0-10.0% of the total weight into a mixing tank, start stirring, and add 24.5% of the total weight ~33.0% of coating base material 2, after stirring for 30~60min, add active antirust agent 3 accounting for 12.0~19.0% of total weight and active antirust agent 4 accounting for 12.5~20.0% of total weight, accounting for 3.0~ 6.0% of active antirust agent 5, then add 5.0% of total weight dispersant TA-100-50, stir for 100-150 minutes to make a slurry, put the slurry into a sand mill and grind for 100-120 minutes, then add Mixed solvents accounting for 12.5-17.5% of the total weight, adjusted for viscosity, stirred for 30 minutes as component A of metal anti-corrosion coatings, packed in barrels. Use curing agent such as polyisocyanate or amine N75 as component B of metal anti-corrosion co...

Embodiment 1

[0041] 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% mica iron oxide and iron-titanium powder (wherein mica iron oxide: iron-titanium powder=1:1), account for 6% of total weight titanium nanopolymer and coal base polyaniline (wherein titanium nanopolymer: coal-based polyaniline=0.3:5.7), then add the dispersant TA-100-50 accounting for 5% of the total weight, stir at a high speed for 100min to become a slurry, 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, pa...

Embodiment 2

[0043] 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 successively add 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 nanopolymer: coal-based polyaniline=1:2), then add the dispersant TA-100-50 accounting for 5% of the total weight, stir at a high speed for 150min to become a slurry, and then put the material 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 coat...

Abstract

The invention discloses a long-acting metal anti-corrosion coating for metal structural parts and metal equipment anti-corrosion and its manufacturing process, which consists of modified polymer organic compound coal tar pitch, organic polymer modified resin, active anti-rust Blending agent 3 or 4 or 5 and additives, after stirring, grinding and adjusting viscosity, adding curing agent. This kind of metal anti-corrosion coating uses the electrochemical mechanism of metal corrosion and adopts a new preparation process. It has extremely excellent super weather resistance and corrosion resistance. It can work under the conditions of rust, water and oil, and can be widely used. Anti-corrosion engineering such as metal structural parts, equipment, buildings (structures), underground engineering and ships in various environments.

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...
