DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to iron and nickel alloys.
The present invention relates to a rust preventive liquid for preventing rust from occurring in parts and products made of metal such as chrome, tin, lead, and casting materials.

[0002]

2. Description of the Related Art Conventionally, rust prevention is performed by applying rust-preventive oil to a metal surface to be rust-prevented. The application of this rust-preventive oil alone did not result in a long rust-proof endurance period and increased the number of applications. Also, it took a long time from the application to the appearance of the rust-preventive effect. Furthermore, in the case of dew condensation, it has to be strengthened and applied, and the cost for maintaining rust has increased. It is also known to use a vaporizable rust inhibitor to prevent rust, but this is done by placing the product to be rusted in a closed room, vaporizing the rust inhibitor and placing the product in an atmosphere of rust inhibitor. It prevents rust. This rust-prevention method could not be expected to have a rust-preventive effect in open outdoor areas, rooms, factories, and large rooms, and was weak.

[0003]

The problem to be solved by the present invention is to solve these problems of the prior art, to make the rust prevention effect possible for a long number of days (long endurable days), to have a quick effect, and to form dew condensation. An object of the present invention is to provide an excellent vaporizable rust preventive agent, which does not lower the rust preventive effect. Another subject of the present invention is:
It can be used in products and processes where oil cannot be used, and provides a sufficient rust-preventive effect even in places with high water and humidity.

[0004]

Means for Solving the Problems The constitution of the present invention which has solved the above problems is as follows: 1) A vaporizable rust inhibitor characterized by mixing a vaporizable rust inhibitor with normal propanol. 2) A vaporizable rust inhibitor. And normal propanol and rust preventive oil
3) A volatile rust preventive liquid characterized by admixing with water 3) A vaporizable rust preventive, normal propanol, and no oil
A vaporizable rust-preventive liquid characterized by being mixed with a liquid 4) the vaporizable rust-preventive liquid according to the above 3), wherein the non-oil liquid is water 5) the vaporizable rust-preventive agent is cyclohexyl-cyclohexyl
The vaporizable rust preventive liquid according to any one of the above 1) to 4), wherein the liquid comprises a milkamine as a main component .

[0005]

According to the present invention, a vaporizable rust inhibitor such as cyclohexyl-cyclohexylamine is mixed. Therefore, when the vaporizable rust inhibitor is applied to the metal surface and sprayed, the vaporizable rust inhibitor and rust-preventive oil are applied. A non-oil rust preventive solution such as an alcohol solution or water coats the metal surface in a film-like manner. After adhering to the surface, the vaporizable rust preventive vaporizes and the rust preventive effect is quickly developed. Further, the rust-proofing days can be extended by covering the metal surface with a rust-preventive oil and a non-vaporized vaporizable rust preventive agent in the film. or,
Water can also be used as a non-oil rust preventive liquid. Also, it can be used without deteriorating the rust prevention effect against dew condensation. Alcohol solution and water can also be used as non-oil stick liquid, and can be manufactured at low cost. In this case, it is effective for a product that cannot use oil or a product in a process where it is difficult to use oil.
In addition, since water functions as a rust-preventive liquid even in places with a lot of water, moisture, and dew, the rust-preventing effect can be maintained and used in these places.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As the vaporizable rust preventive liquid of the present invention,
Soft crystalline cyclohexyl-cyclohexylamine (N-CYCLOHEXYL-CYCLOHEXAM)
INE), cyclohexyl benzylamine (4CYC
LOHEXI-BENZENAMINE), and cyclohexanol (CYCLOHEXANO)
L), cyclohexanone (CYCLOHEXANON)
E) and the like, and as a product, Ferroguard 100E (trade name, sales company USC) is known. The mixing ratio of this volatile rust inhibitor is practically 10% by weight.
In the case where the mixture is as follows, the others are mainly composed of rust-preventive oil, and the case of mainly composed of an alcohol solution, the alcohol solution may be mixed with a large amount of water in some cases. For products and processes where oil can be used, those containing rust-preventive oil are preferable because they can prevent rust for a long period of time. When oil cannot be used, it is preferable to mix an alcohol solution or water. The alcohol solution of the present invention is preferably normal propanol, but is not limited thereto. As the rust-preventive oil or rust-preventive liquid other than oil, oil / water which is well mixed with a vaporizable rust-preventive agent is used, and the mixing ratio is practically 70 to 90% by weight.

[0007]

The present invention will be described below with reference to examples. Example 1 The vaporizable rust inhibitor of Example 1 was cyclohexyl-cyclohexylamine (N-CYCL) as a vaporizable rust inhibitor.
OHEXYL-CYCLOHEXAMINE and cyclohexyl benzylamine (4CYCLOHEXY-B
ENZENAMINE) Ferroguard 10 consisting of others
0E (brand name, sales company USC)
76% by weight of Daphne Oil Coat Z3 (trade name, sales company Idemitsu Kosan Co., Ltd.) as anticorrosive oil, and 16% by weight of normal propanol as an alcohol solution
Was mixed. As the rust preventive treatment of the end face of the coil of the steel sheet, the case where the vaporizable rust preventive agent of Example 1 was applied, the case where only the rust preventive oil of Daphne oil coat Z3 was applied, the case where no rust preventive treatment was performed, When the degree of rust generation was compared and observed, the number of durable days (the number of days from application in which rust was observed) was as shown in Table 1 below. Table 1 Treatment Endurance days Rust prevention of the coating of Example 1 70 days Rust prevention only with rust prevention oil 41 days No treatment 20 days As can be seen from Table 1, the rust inhibitor of Example 1 In this case, the number of days to withstand about 70% can be prolonged, and the expression of the rust-preventive effect is also quickened.
Also, in order not to strictly generate rust on the end face of the coil, re-application must be performed earlier than this endurance period.
In the case of the first embodiment, the recoating was performed about one fifth of the case of only the rust preventive oil. Furthermore, when the wetting test was performed for the case of Example 1 and the case of using only the above rust-preventive oil and the state of rust generation was observed, the results in Table 2 below were obtained. Wetness test: Test temperature 60 ° C Test humidity 95% Test time 240 hours Table 2 (Results of wet test) Results of Example 1 No rusting Result of only rust-preventive oil Medium rust Measures of this humidity, measures against dew condensation In the case of rust prevention using only rust-preventive oil, wiping requiring dew condensation is required, but in Example 1, wiping was unnecessary. Example 2 Example 2 is an example in which a volatile rust inhibitor was mixed with an alcohol solution. 3% by weight of the same ferroguard 100E (trade name) as in Example 1 as the vaporizable rust inhibitor of Example 2
Is a rust preventive mixed in 97% by weight of normal propanol. This rust preventive is effective when it is necessary to avoid oil to which no oil can be applied, or oil which has no oil removing step on the surface of an intermediate product. The second embodiment is different from the first embodiment.
The same good rust-preventing effect was obtained. The endurance days in an indoor environment (such as a factory) were about 60 days. Example 3 Example 3 is an example in which a vaporizable rust preventive, an alcohol solution and a non-oil rust preventive liquid are mixed. 3% by weight of the above ferroguard 100E (trade name) as a vaporizable rust inhibitor;
8% by weight of normal propanol as an alcohol solution and 89% by weight of water as a non-oil-based rust preventive liquid were mixed. Example 3 also had a rust-preventing effect close to that of Example 1. In an indoor environment such as a factory, the endurance days were about 40 days. The rust preventive of Example 3 is a product which cannot use oil.
Can be used in the process. In particular, it is effective for use in places and processes where there is a lot of moisture, moisture, and dew.Even if there is moisture or moisture, it is integrated with the water in the rust preventive agent to form a rust preventive film, which reduces the rust preventive effect. Does not occur.

[0008]

As described above, according to the present invention, the rust preventive effect can be maintained for a long period of time, the number of times of applying the rust preventive agent can be reduced, and the rust preventive cost can be reduced. Further, the rust-preventing effect can be exhibited at an early stage, and is less affected by the presence of water and moisture. Products that do not use rust-preventive oil and are difficult to use oil, intermediate products,
There is an effect that it can be used also in the process.
