Description
Technical Field
The invention relates to a metal preservative and a manufacturing method thereof, belonging to the technical field of metal corrosion prevention.
Background
Corrosion of metals is the most common form of corrosion. During corrosion, a chemical or electrochemical multiphase reaction occurs at the interface of the metal, causing the metal to change to an oxidized (ionic) state. This can significantly reduce the mechanical properties of the metal material such as strength, plasticity, toughness, etc., destroy the geometric shape of the metal member, increase the wear between parts, deteriorate the physical properties of electricity, optics, etc., shorten the service life of the equipment, and even cause disastrous accidents such as fire, explosion, etc. According to statistics, the economic loss caused by steel corrosion accounts for about 4% of global GDP every year, so how to effectively prevent corrosion is always a hotspot and difficulty of research in the industry. Currently, steel has been protected from corrosion by various means, and the application of rust inhibitive coatings is one of the main methods for preventing corrosion of steel.
The existing antirust agent has the defect of common anticorrosion effect.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: provides a metal preservative and a manufacturing method thereof, which solve the problem that the anti-corrosion effect of the antirust agent in the prior art is common.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a metal preservative, which comprises 8-10 parts of silicone oil; 5-10 parts of oil-soluble phenolic resin; 1-4 parts of sodium tripolyphosphate; 80-100 parts of deionized water; 1-5 parts of ethanol; 0.5-1.5 parts of sodium dodecyl sulfate; 1-3 parts of graphene; 0.5-1.5 parts of metal organic framework compound.
As a preferred example, the metal organic framework compound is MOF-14.
A method for producing a metal corrosion inhibitor, comprising the steps of:
step S1: putting the oil-soluble phenolic resin dissolved in advance into a stirring cylinder;
step S2: adding deionized water, ethanol and sodium dodecyl sulfate into a stirring cylinder in proportion, and fully and uniformly stirring;
step S3: fully stirring the graphene and the MOF-14, and slowly adding the mixture;
step S4: adding sodium tripolyphosphate, and stirring to remove bubbles to obtain antiseptic slurry.
The invention has the beneficial effects that:
1. graphene effectively blocks the passage of gas atoms such as water and oxygen. Studies have shown that graphene provides good protection to metal substrates even when exposed to oxygen partial pressures up to 10 "4 mbar. Therefore, the graphene is used as a metal protective coating, so that the graphene can be prevented from contacting with corrosive or oxidative media, and a good protective effect is achieved on a substrate material; meanwhile, the graphene can also perform a passivation effect on the plating metal, so that the corrosion resistance of the coating is further improved.
The MOF-14 has a chain structure, and is helpful for increasing the specific surface area, so that raw materials are adsorbed, and a compact membrane structure is formed on the surface of the raw materials, so that the corrosion resistance is further improved.

The manufacturing method of the metal preservative comprises the following steps:
step S1: putting the oil-soluble phenolic resin dissolved in advance into a stirring cylinder.
Step S2: deionized water, ethanol and sodium dodecyl sulfate are proportionally added into a stirring cylinder, and then the mixture is fully and uniformly stirred.
Step S3: fully stirring the graphene and the MOF-14, and slowly adding the mixture into a stirring bar.
Step S4: adding sodium tripolyphosphate, and stirring to remove bubbles to obtain antiseptic slurry.
The graphene in the invention effectively blocks the passing of gas atoms such as water and oxygen. Studies have shown that graphene provides good protection to metal substrates even when exposed to oxygen partial pressures up to 10 "4 mbar. Therefore, the graphene is used as a metal protective coating, so that the graphene can be prevented from contacting with corrosive or oxidative media, and a good protective effect is achieved on a substrate material; meanwhile, the graphene can also perform a passivation effect on the plating metal, so that the corrosion resistance of the coating is further improved.
The metal-organic framework compound is an organic-inorganic hybrid material with intramolecular pores formed by self-assembly of organic ligands and metal ions or clusters through coordination bonds. The MOF-14 material has a good interlocking structure, and is beneficial to increasing the specific surface area, so that raw materials are adsorbed, and a compact film structure is formed on the surface of the raw materials, so that the corrosion resistance is further improved.
