Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with examples.

[0027] (1) Preparation of functionalized MoSe2 nanosheets: Melamine and phytic acid were prepared into 0.05wt% and 1wt% solutions, respectively.

[0028] ① Dissolve phytic acid in a solution of ethanol and water (ethanol: water = 95:5) at room temperature to form a mixed solution with a concentration of 2g / L. At room temperature, the MoSe2 nanosheets were soaked in this solution, and after 2 hours, the solution was centrifuged three times with a centrifuge, rinsed three times with deionized water, and finally dried with nitrogen for later use.

[0029] ② Put the above-mentioned MoSe2 nanosheets in the prepared melamine solution for 30 minutes, centrifuge the solution 3 times in a centrifuge, rinse 3 times with distilled water, and blow dry with nitrogen;

[0030] ③ Put the melamine-adsorbed MoSe2 nanosheets in the prepared phytic acid solution for 30 minutes, centrifuge the solution...

Abstract

A method for preparing a water-based anti-corrosion and fire-proof coating material for steel structures relates to a method for preparing a coating. 2 ) nanosheets to construct melamine and its salt-phytic acid flame retardant layer, and functionalized molybdenum diselenide nanosheets are filled into waterborne epoxy resin to prepare water-based anticorrosion and fireproof coating for steel structure. The method improves the flame retardant performance of waterborne epoxy resin by constructing a P-N flame retardant layer; the phytic acid in the nanofiller has a huge chelating potential energy, which makes it connect the coating and the substrate in a stronger way to improve the The corrosion resistance and durability of the coating; also successfully solved the problem of easy agglomeration of nanomaterials due to their high surface energy.

Description

technical field [0001] The invention relates to a coating preparation method, in particular to a preparation method of a steel structure water-based anticorrosion and fireproof coating material. Background technique [0002] Metal corrosion is a phenomenon in which metal materials are destroyed by chemical or electrochemical reactions, which poses a serious threat to the national economy and industrial structure. Therefore, corrosion protection plays a very important role in the modern metalworking industry. However, corrosion cannot be completely suppressed. Currently uncontroversial methods include cathodic protection, brush application of protective coatings and addition of corrosion inhibitors, or any combination of the above, with the use of protective coatings being the most widely used method. A current challenge regarding protective coatings is novel multifunctional materials as corrosion inhibitors that can meet different environmental demands due to their excelle...
