This illustrates: in the preparation process of the rust-proof metal material, compared with the pretreated metal wire obtained by adopting the metal wire which is not pretreated, the rust-proof performance of the prepared rust-proof metal material under the conditions of high temperature and high humidity can be greatly improved.
The antirust metal material prepared in the example 4 has a wet-heat antirust day at the temperature of 35 ℃ which is greatly higher than that of the antirust metal material prepared in the example 1 at the RH of 85%; and is also substantially higher than the rust inhibitive metal materials prepared in examples 2 and 3. This illustrates: the choice of the treating agent plays an important role in greatly improving the rust resistance of the prepared rust-proof metal material under the conditions of high temperature and high humidity of the pretreated metal wire obtained after the treatment. The invention discovers that the pretreated metal wires obtained after being treated by adopting different treating agents have different rust resistance on the prepared rust-proof metal material under the conditions of high temperature and high humidity; the pretreated metal wire is obtained after treatment by adopting a treating agent consisting of coconut monoethanolamide sulfosuccinic acid monoester disodium and dodecyl diphenyl ether disulfonate, so that the rust resistance of the prepared rust-proof metal material under the conditions of high temperature and high humidity can be further greatly improved; the degree of improvement of the rust-proof performance of the prepared rust-proof metal material under the high-temperature and high-humidity conditions is greatly higher than that of a pretreated metal wire obtained after the treatment of the single treatment agent of disodium cocoate monoethanolamide sulfosuccinate or sodium dodecyl diphenyl ether disulfonate. The pretreatment agent is composed of coconut acid monoethanolamide sulfosuccinic acid monoester disodium and dodecyl diphenyl ether disulfonate, so that the rust-proof performance of the prepared rust-proof metal material under the conditions of high temperature and high humidity can be synergistically improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
