Abstract
A gas phase antirust paper for multiple metals and a preparation method thereof. The composite gas-phase slow-release layer comprises the following components in percentage by mass: 10-30% of sodium benzoate; 10-30% of 2, 6-dimethoxy 1, 4-benzoquinone; 10-25% of benzotriazole; 5-20% of 2, 4-di-tert-butyl-4-methylphenol; 10-20% of methyl phenyl carbamate; 5-15% of 2-methylpyrimidine; 10-30% of abietic acid amide borate compound; 10-30% fumed silica. The compound vapor phase corrosion inhibitor is fully fused and interacted under the regulation of a nonionic surfactant, namely abietic acid amide borate; the fumed silica can be used as a support body of the vapor composite corrosion inhibitor, so that the specific surface area of the fumed silica is greatly improved, the fumed silica can be fully volatilized to the metal surface to form a protective film, and the vapor antirust performance can be better exerted through the synergistic effect.
Description
The technical field is as follows:
the invention relates to the field of nontoxic gas-phase antirust paper products suitable for various metal products, in particular to gas-phase antirust paper for various metals and a preparation method thereof.
Background art:
the gas phase rust prevention technology is one of the important methods of non-contact rust prevention at present. It uses vapor phase Corrosion Inhibitor (VCI) to automatically volatilize gas at normal temperature to form a layer of protective film on the metal surface, thus inhibiting the generation of electrochemical reaction, and simultaneously blocking the Corrosion of some substances (such as water, oxygen and other acidic gases) which accelerate the Corrosion of the metal to the metal surface, thereby slowing down or preventing the Corrosion to the metal surface. Common packaging use forms are gas-phase rust preventive powder: placing a certain amount of vapor phase inhibitor in a packaging container or a sealed space; antirust paper: coating a vapor phase inhibitor on the base paper; gas-phase antirust film: the corrosion inhibitor is added to the plastic film. In the three using modes, the gas phase corrosion inhibitor continuously and slowly volatilizes through sublimation to form corrosion inhibitor gas, and the gas phase corrosion inhibitor gas diffuses to the surface of the metal and is communicated with the surface of the metal to form a molecular film through chemical bonds or adsorption, so that the corrosion on the surface of the metal is effectively inhibited.
The gas-phase antirust paper has a long history of being used for surface protection packaging of metal products, has the characteristics of non-contact antirust no dead angle, environmental friendliness, convenient use, cleanness and the like compared with the traditional antirust oil and water-soluble antirust liquid, and has been widely applied to the antirust corrosion of the production, transportation, storage and other links of metals and products thereof in recent years. In the effective chemical components used as the gas phase corrosion inhibitor at present, the nitroso-based corrosion inhibitor still occupies a great proportion, but researches have clearly shown that nitroso and secondary amine are easily converted into a strong carcinogen nitrosamine in organisms, and the waste gas phase antirust paper after being used can cause great pollution to the environment. On the other hand, part of the vapor phase corrosion inhibitor has a deliquescence phenomenon, can reduce the mechanical strength of the antirust packaging paper in the storage process, and is easily damaged by edges and corners of steel materials in the use process. Although researchers use a large amount of industrial modified zeolite to improve the performance of the anti-rust paper, the production of the industrial modified zeolite is harmful to the health of operators and pollutes the environment, and fire accidents easily occur, so that the safe production has potential risks. Furthermore, the use of industrially modified zeolites does not impose any particular requirements on their particle size, and they do not function as large as possible as a support for the dispersed vapor phase corrosion inhibitor. In addition, at present, the components in the formula of the gaseous corrosion inhibitor in most of the gaseous rust-proof paper are simply mixed physically or dissolved and mixed, and are connected with each other without proper surface active molecules, so that the components of the gaseous corrosion inhibitor cannot be completely fused with each other, and the gaseous rust-proof function of the gaseous corrosion inhibitor can be fully exerted.
Therefore, the development and production of the gas phase antirust paper which has excellent antirust effect on multiple metals, is environment-friendly and is simple and convenient to operate has important significance for solving the problem of corrosion in the process of storing and transporting metal products.
The nonionic surfactant can well link the components of the vapor phase corrosion inhibitor together, promote the mutual fusion of the components and fully exert the vapor phase corrosion inhibition performance of the components; meanwhile, the surface tension of the liquid can be greatly reduced, the wettability is enhanced, and the components of the vapor phase corrosion inhibitor are firmly and uniformly attached to the vapor phase anti-rust paper. The abietic acid amide borate prepared by using unsaturated acid, alcohol amine and boric acid which are abundant in natural resources as raw materials has a hydrophobic group and also contains a plurality of hydrophilic groups such as hydroxyl, amide and the like, so that the abietic acid amide borate has high surface activity and strong wetting capability, and has a dissolution promoting effect on organic gas phase molecules. More importantly, the amino and borate contained in the molecules of the abietic acid amide borate can be used as an extreme pressure lubricant, a dispersion stabilizer, an adsorbent, an antirust agent and a wetting agent. However, their use as additives in gas-phase anti-rust paper technology has not been reported.
