Problems solved by technology

However, the release of the active ingredients of the corrosion inhibitor is uncontrollable for general corrosion-inhibiting coatings, which will lead to the rapid consumption of the self-healing ability of the coating, and even osmotic blistering.

Embodiment 1

[0018] A kind of zinc complex nano-container of loading corrosion inhibitor, its preparation method can comprise: 0.32g 2,5-furandicarboxylic acid, 0.24g benzotriazole and 0.59g zinc nitrate are mixed, and add to 50mL N, The aqueous solution of N-dimethylformamide was stirred for 10 minutes, then placed in an oven at 120° C. for 72 hours, and a zinc complex nanocontainer loaded with a corrosion inhibitor in the form of colorless block crystals was obtained after cooling.

[0019] Specifically, the structure of the zinc complex nanocontainer loaded with corrosion inhibitor prepared in Example 1 of the present invention was determined by using a single crystal diffractometer, so that the following can be obtained: figure 1 The crystallographic asymmetric unit diagram shown and the crystal structure data described in Table 1 below:

Embodiment 2

[0025] Adding the zinc complex nanocontainer loaded with corrosion inhibitor provided in Example 1 of the present invention to the organosilane coating and applying it to the anticorrosion method of aluminum alloy is as follows:

[0026] (1) Mix absolute ethanol and deionized water evenly, then add GPTMS (trimethoxysilane), and stir at room temperature for 1 hour to obtain Sol A.

[0027] (2) Add a certain amount of absolute ethanol, acetyl ethyl acetate, TEOS (tetraethyl orthosilicate) and glacial acetic acid in sequence, and stir at room temperature for 1 hour to obtain Sol B.

[0028] (3) Mix sol A and sol B, stir at room temperature for 30 minutes, then add 1 g / L zinc complex nanocontainer loaded with corrosion inhibitor prepared in Example 1 of the present invention, and continue stirring for 30 minutes. The sol is generally aged for one day, and dipped after the ingredients are mixed evenly.

[0029] (4) Set the pulling speed of the pulling machine to 10cm / min, dip-coat...

Embodiment 3

[0032] Adding the zinc complex nano-container loaded with corrosion inhibitor provided in Example 1 of the present invention to the epoxy primer and applying it to the anticorrosion method of steel is as follows:

[0033] (1) Add 5 g / L zinc complex nanocontainer loaded with corrosion inhibitor provided in Example 1 of the present invention to the epoxy primer, and stir mechanically for 30 minutes until the mixture is uniform.

[0034] (2) Set the pulling speed of the pulling machine to 10cm / min, dip-coat the polished and cleaned carbon steel Q235 samples once respectively, and cure at room temperature for 24 hours to obtain the film layer. It can be seen from the film layer that the continuity of the epoxy primer film layer is not affected after adding the zinc complex nano container powder of the load corrosion inhibitor provided in Example 1 of the present invention, and the corrosion resistance of the paint film can be effectively improved .

[0035] In summary, the embodi...

Abstract

The invention discloses a corrosion inhibitor supported zinc complex nano container as well as a preparation method and application thereof. The chemical structure formula is {[Zn(FDA)(BTA)]-*(Me2NH2)<+>}n, in the formula, FDA is proton abstracted 2,5-furanedioic acid, BTA is proton abstracted benzotriazole, and Me2NH2 is dimethylamine cation. The preparation method comprises the following steps:mixing 2,5-furanedioic acid, benzotriazole and zinc nitrate, adding into a water solution of N,N-dimethyl formamide, carrying out stirring for 10 minutes, leaving the mixture to stand for 24-72 hoursin a baking oven at 120 DEG C, and carrying out cooling, so as to obtain the container. The corrosion inhibitor supported zinc complex nano container is adopted for corrosion protection of metals. Thecontainer not only is capable of achieving effective supporting and release of a corrosion inhibitor, but also can be compounded with an organic coating for corrosion protection of the metals, and the corrosion resistance life of an organic coating can be prolonged.

Description

technical field [0001] The invention relates to the technical field of metal corrosion and protection, in particular to a zinc complex nano container loaded with a corrosion inhibitor and a preparation method and application thereof. Background technique [0002] Metal corrosion is a phenomenon in which a metal material reacts chemically or electrochemically with the surrounding environment, resulting in the failure of the metal material. Metal corrosion is universal, concealed, gradual and sudden, which brings direct economic losses and a large number of economic accidents. [0003] In recent years, with the in-depth study of the metal corrosion mechanism, people began to use corrosion-inhibiting coatings to protect the metal surface. However, general corrosion-inhibiting coatings cannot control the release of the active ingredients of corrosion inhibitors, which will lead to rapid consumption of the self-healing ability of the coating, and even osmotic blistering.
