Definitions

  • the present invention relates to a water-based coolant and, in particular, to a water-based coolant usable, for instance, for quenching a metal component.
  • Coolants (quenchants) usable for, for instance, quenching metal components are mainly categorized into an oil-based quenchant and a water-based quenchant (an aqueous solution), the oil-based quenchant being frequently used.
  • oil-based quenchant which exhibits an appropriate cooling performance, results in a reduced quenching distortion and thus in avoidance of quenching cracks.
  • the cooling speed is slow and the cooling performance is insufficient. Accordingly, the water-based quenchant is used.
  • the cooling performance of which is higher than that of the oil-based quenchant uneven cooling is likely to occur and thus quenching cracks may be caused.
  • Quenching with a saline solution has been known for a long time as a technique of improving an uneven-cooling resistance.
  • the saline solution which does not experience a steam film stage, exhibits a high uneven-cooling resistance as well as a high cooling performance and thus reduces quenching cracks (see Non-Patent Literature 1).
  • rust forms in quite a short time of one hour or less after the start of a quenching treatment, resulting in severe corrosion of equipment such as an oil bath. Accordingly, the saline solution is hardly used in an industrial application.
  • Patent Literature 1 or 2 may cause the corrosion of a metal material to be cooled.
  • An object of the invention is to provide a water-based coolant that is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled.
  • a water-based coolant contains: at least one inorganic acid salt selected from among carbonate, hydrogen carbonate, sesquicarbonate, phosphate, borate, molybdate and tungstate; and a metal corrosion inhibitor.
  • the metal corrosion inhibitor is at least one compound selected from among a benzotriazole compound, a benzimidazole compound, a benzothiazole compound and a benzothiadiazole compound.
  • the water-based coolant further contains a bactericide.
  • a content of the bactericide is in a range from 0.001 mass % to 0.5 mass % of a total amount of the coolant.
  • a content of the inorganic acid salt is in a range from 1 mass % to 20 mass % of a total amount of the coolant.
  • a content of the metal corrosion inhibitor is in a range from 0.01 mass % to 1 mass % of a total amount of the coolant.
  • the inorganic acid salt is an inorganic acid metal salt.
  • the inorganic acid salt is at least one of a sodium salt, a potassium salt, a calcium salt and a magnesium salt.
  • the phosphate is at least one of orthophosphate, hydrogenphosphate, dihydrogenphosphate, polyphosphate and metaphosphate.
  • the water-based coolant is used as a quenching oil or a cutting oil.
  • the above aspect of the invention can provide a water-based coolant that is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled.
  • a water-based coolant (hereinafter occasionally simply referred to as “the present coolant”) is provided by blending a specific inorganic acid salt and a metal corrosion inhibitor.
  • the present coolant will be described below in details.
  • Examples of the inorganic acid salt in the present coolant include carbonate, hydrogen carbonate, sesquicarbonate, phosphate, hydrosulfate, borate, molybdate and tungstate.
  • the above salts may be used alone or mixed in use.
  • carbonate, hydrogen carbonate, sesquicarbonate and phosphate are preferable in terms of cooling effect.
  • Carbonate and hydrogen carbonate are preferably mixed in use for the purpose of pH control.
  • Phosphate may be any one of orthophosphate, hydrogenphosphate, dihydrogenphosphate, polyphosphate and metaphosphate.
  • polyphosphate include diphosphate (pyrophosphate) and tripolyphosphate. Among the above, pyrophosphate is preferable in terms of cooling effect.
  • the above phosphates may be used alone or mixed in use.
  • the above phosphates may be mixed with the inorganic salt.
  • the inorganic acid salt is preferably a metal salt, specific examples of which include sodium salt, potassium salt, calcium salt and magnesium salt. Among the above, sodium salt and potassium salt are preferable in terms of cooling performance.
  • the present coolant preferably has a pH of 7 or higher in terms of corrosion resistance.
  • the content of the inorganic acid salt in the present coolant is preferably in a range from 1 mass % to 20 mass % of the total amount of the present coolant and more preferably in a range from 3 mass % to 15 mass %.
  • the cooling effect may be insufficient.
  • the content of the inorganic acid salt exceeds 20 mass %, a significant improvement in the cooling effect is not promising.
  • the present coolant contains the metal corrosion inhibitor.
  • the metal corrosion inhibitor include a benzotriazole compound, a benzimidazole compound, a benzothiazole compound and a benzothiadiazole compound.
  • the above compounds may be used alone or mixed in use.
  • benzotriazole compound includes benzotriazole and derivatives thereof. The same applies to the benzimidazole compound, the benzothiazole compound and the benzothiadiazole compound.
  • benzotriazole compound examples include: alkylbenzotriazole in which a benzene ring is substituted with an alkyl group; and (alkyl)aminoalkyl benzotriazole in which hydrogen of an amino group is substituted with an alkyl group.
  • the content of the metal corrosion inhibitor is preferably in a range from 0.01 mass % to 1 mass % of the total amount of the present coolant and more preferably in a range from 0.1 mass % to 0.7 mass %.
  • the content of the metal corrosion inhibitor is less than 0.01 mass %, the metal corrosion resistance effect may be insufficient. In contrast, even when the content of the metal corrosion inhibitor exceeds 1 mass %, a significant improvement in the metal corrosion resistance effect is not promising.
  • the present coolant may further contain a bactericide as needed.
  • the bactericide include a benzisothiazoline compound, an isothiazoline compound, a triazine compound and a pyrithione compound.
  • the benzisothiazoline compound includes benzisothiazoline and derivatives thereof The same applies to the isothiazoline compound, the triazine compound and the pyrithione compound.
  • benzisothiazoline compound examples include benzisothiazoline, 1,2-benzisothiazoline-3-one, 2-methyl isothiazoline-3-one and 5-chloro-2-methyl-4-isothiazoline-3-one.
  • triazine compound examples include hexahydro-1,3,5-tris-(2-hydroxyethyl)triazine.
  • pyrithione compound examples include sodium pyrithione.
  • the content of the bactericide is preferably in a range from 0.001 mass % to 0.5 mass % of the total amount of the present coolant and more preferably in a range from 0.01 mass % to 0.4 mass %.
  • the content of the bactericide is less than 0.001 mass %, a sufficient antibacterial effect may not be obtained. In contrast, even when the content of the bactericide exceeds 0.5 mass %, a significant improvement in the antibacterial effect is not promising.
  • the present coolant may further contain a water-soluble rust inhibitor as needed.
  • the content of the water-soluble rust inhibitor is preferably in a range from 0.01 mass % to 5 mass % of the total amount of the present coolant and more preferably in a range from 0.03 mass % to 1 mass %.
  • the water-soluble rust inhibitor include aliphatic monocarboxylates such as octanate, and aliphatic dicarboxylates such as octanedioic acid (suberate) salt and decanedioic acid (sebacate) salt, among which potassium sebacate or the like is preferably usable.
  • Aromatic carboxylates may be used as the water-soluble rust inhibitor.
  • a piperazine derivative such as monohydroxy monoethyl piperazine may also be favorably used as the water-soluble rust inhibitor.
  • the present coolant may further contain typical additives such as an antioxidant and a detergent dispersant.
  • the present water-based coolant which does not experience a steam film stage, exhibits a high cooling performance. Further, the present water-based coolant is unlikely to cause corrosion of a metal material to be cooled, and thus is suitably usable as a quenching oil or a cutting oil for metal materials.
  • Sample solutions were prepared by blending an ion-exchange water with the following additives. It should be noted that Table 1 additionally indicates the pH of each of the sample solutions.
  • a sample of Reference Example consisted solely of an ion-exchange water without addition of any additive.

  • the sample solutions kept at 50 degrees C. were each subjected to a cooling test according to JIS K2242B to measure characteristic seconds. Specifically, time (seconds) elapsed before a temperature where a steam film stage came to an end (i.e., a characteristic temperature) was reached according to a cooling curve was measured. The results are shown in Table 1.
  • a metal material (S45C) was half-immersed at 30 degrees C. for three days, and then evaluated in terms of the degree of corrosion based on the following standards. The results are shown in Table 1.
  • the water-based coolants according to the invention each of which is a solution prepared with a specific inorganic acid salt, achieve significantly short characteristic seconds and exhibit a considerably high cooling performance. Further, the water-based coolants according to the invention are each unlikely to cause corrosion of a metal material with the assistance of the metal corrosion inhibitor added thereto. Therefore, it can be understood that the water-based coolants according to the invention are considerably effective in quenching or cutting a metal material.
  • the water-based coolants according to the invention each exhibit an excellent antibacterial effect with the assistance of the bactericide added thereto, whereas the water-based coolants according to Comparatives sometimes fail to exhibit an antibacterial effect even when the same bactericide is added thereto.
  • the cooling performance of water is sharply decreased to be insufficient for quenching.
  • the water-based coolants according to the invention each exhibit an excellent cooling performance even when the fluid temperature reaches 50 degrees C.
  • the ion-exchange water of Reference Example which is devoid of the specific inorganic acid salt according to the invention, is insufficient in cooling performance. Addition of an inorganic acid salt different from the inorganic acid salt according to the invention or an organic acid salt does not lead to improvement in cooling performance.
  • the coolant according to the invention which is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled, is usable as a quenchant (quenching oil) or a cutting oil for metal materials.
