Description

  The present invention relates to a wet wire drawing lubricant, a wet wire drawing method and an additive for a wet wire drawing lubricant used in the wet wire drawing lubricant. Lubricant for wet wire drawing of brass-plated steel wire (hereinafter also simply referred to as “steel cord”) for reinforcing rubber articles (hereinafter simply referred to as “lubricant”) used for steel cords used for reinforcement in rubber articles And a wet wire drawing method (hereinafter also simply referred to as “wire drawing method”) and a wet wire drawing lubricant additive (hereinafter also simply referred to as “lubricant additive”).

  Steel cords for reinforcing rubber articles used for reinforcing rubber articles such as tires are usually obtained by drawing brass-plated wire (steel wire) to a desired wire diameter to obtain steel filaments. Manufactured by twisting together as appropriate. This wire drawing process is generally performed using a slip-type multistage wire drawing machine 10 as shown in FIG.

  In the illustrated slip type multi-stage wire drawing machine 10, two multi-stage drive capstans 13A and 13B are arranged opposite to each other in a lubricating liquid tank 12 filled with a lubricant 11. In the process of alternately passing the steel wires 1 through the dies 14 to the respective stages of the capstans 13A, 13B, the steel wires 1 are drawn by the dies 14 at each stage. The drawn steel wire 1 is sent to the winding process from the drive capstan 15 disposed outside the lubricating liquid tank 12 through the final die 16.

  When wet drawing of the steel wire 1 is performed using the slip-type multistage wire drawing machine 10 and the lubricant 11, conventionally, a zinc complex of a phosphate ester or the like is used as an extreme pressure coating to draw the wire. A technique has been used in which friction between a die and a wire is reduced to suppress damage to the die and the wire. This has played a very important role in producing steel wires and thus steel cords with high productivity.

  As an improved technique related to the wet drawing process of steel wire subjected to such brass plating, for example, Patent Document 1 uses a lubricant containing zinc and one or both of cobalt and nickel. A method of drawing a steel wire that combines high productivity and low cost with excellent initial adhesion of the wire has been reported. Further, Patent Document 2 uses a lubricant containing either one or both of cobalt and nickel, and provides a similar effect by passing a slip speed in a drive capstan through a predetermined drawing path. Realized steel wire drawing methods have been proposed.

  Patent Document 3 discloses that an organic carboxylic acid amine salt, an organic phosphate ester amic acid, and a specific organic metal are used for the purpose of improving the drawing processability and improving the adhesion of the resulting wire drawing material to rubber. It has been reported that a lubricant composition containing a predetermined proportion of salt is used.

  Furthermore, Patent Document 4 proposes that a metal salt of benzoic acid is contained in the lubricant in order to enhance the adhesion between the steel wire plated with brass and the rubber.

  When wet drawing is performed as described above, various types of lubricants are used to improve wire drawing workability, suppress damage to dies and wires, and further improve adhesion to rubber. It has played a major role in producing steel cords with high productivity. However, in wire drawing to produce high-strength steel wire, the steel wire to be processed has a high deformation resistance, so the heat generated by the processing increases and the steel wire deteriorates due to age hardening and promotes die wear. Such problems are likely to occur, and the prior art has not been sufficient to solve such problems. Therefore, in wire drawing processing for producing high-strength steel wire, a lubricant for wet wire drawing and a wet wire drawing method that has excellent ductility that is difficult to break, and has little decrease in ductility even when processing such as stranded wire is applied.

Example 1
[Preparation of lubricant additive]
10 g of a nonionic surfactant (Kao Co., Ltd., Emulgen 108, HLB value: 12.1) is mixed with 5 g of a phosphazene derivative compound (a compound in which R ⁴ is an octoxy group in the above general formula (2)), A lubricant additive was prepared by stirring for 30 minutes.

[Addition to lubricant]
The lubricant additive obtained above was added over 5 minutes to 1000 g of the wet lubricant being stirred, and stirring was continued for another 30 minutes after the addition to prepare the lubricant of Example 1. The following liquid stability test was conducted on the obtained lubricant of Example 1, and the results are shown in Table 1.

[Evaluation of liquid stability]
Stirring of the lubricant of Example 1 was stopped, and the state of the lubricant after standing for 24 hours was observed. When observing the lubricant after standing, the suspended matter separated on the liquid surface was found to have good liquid stability when the suspended matter separated on the liquid surface was not seen and sludge settled on the liquid bottom was not observed. As a result, the liquid stability was deteriorated when sludge was observed, or sludge settled at the bottom of the liquid was observed, and this was visually evaluated in five stages. The case where the liquid stability is the best is 5 and the case where the liquid stability is the worst is 1.

(Example 2)
Example 1 [Preparation of lubricant additive] In Example 1, except that the amount of the nonionic surfactant (Kao Corporation, Emulgen 108, HLB value: 12.1) was changed to 20 g. A lubricant additive was prepared and added to the lubricant, and liquid stability was evaluated. The results are shown in Table 1.

(Comparative Example 1)
In Example 1 [Preparation of lubricant additive], the lubricant additive was not prepared, and in [Addition to wet lubricant], a nonionic surfactant (Eugengen 108 manufactured by Kao Corporation, HLB value: 12) .1) and a phosphazene derivative compound (compound in which R ⁴ is an octoxy group in the above general formula (2)) were added separately over 5 minutes, the liquid stability was the same as in Example 1. Evaluation was conducted. The results are shown in Table 1.

(Comparative Example 2)
In Example 2, [Preparation of Lubricant Additive], the lubricant additive was not prepared, and in [Addition to Wet Lubricant], a nonionic surfactant (manufactured by Kao Corporation, Emulgen 108, HLB value: 12) .1) and a phosphazene derivative compound (a compound in which R ⁴ is an octoxy group in the above general formula (2)) were added separately over 5 minutes, the liquid stability was the same as in Example 2. Evaluation was conducted. The results are shown in Table 1.

  FIG. 2 is a schematic diagram showing the behavior in the wet drawing lubricant. Immediately after the mixing of the surfactant 2 and the phosphazene derivative compound 3, each component is present separately (see FIG. 2 (a)), but after mixing and stirring, the mixture of the surfactant 2 and the phosphazene derivative compound 3 (emulsion or A micelle) 5 is formed (see FIG. 2B). In the lubricant before addition of the mixture, the other component 4 is dispersed as an emulsion or micelle 6 (see FIG. 2 (c)), and the shape of the mixture 5 can be maintained even when the mixture 5 is added thereto. A lubricant having good stability can be obtained (see FIG. 2D). On the other hand, when the surfactant 2 and the phosphazene derivative compound 3 are separately added to the lubricant containing the other component 4 (see FIG. 2 (e)), the surfactant 2 is mixed with the other component 4 and the emulsion. Alternatively, micelle 6 is formed, and phosphazene derivative compound 3 is separated (see FIG. 2 (f)). As a result, in Examples 1 and 2, the liquid stability is excellent, while in Comparative Examples 1 and 2, the liquid stability is poor, and it can be seen that the phosphazene derivative compound can be stably present in the lubricant by the effect of the present invention.

  As described above, according to the present invention, when the phosphazene derivative compound was added to the lubricant, it was confirmed that the phosphazene derivative compound was emulsified or dispersed in the lubricant without separation.
