Field of the Invention The present invention relates to a lubricant used for warm forming of a metal material, particularly an aluminum material mainly containing aluminum such as pure aluminum and aluminum alloy. As is well known, warm forming is a method of processing a metal material at a temperature above room temperature and below a recrystallization temperature, but the processing temperature has been confirmed to have a significant effect on the characteristics of material processing, and it is used at that time. The present invention relates to a highly effective aqueous lubricant composition.

かじりの防止等が重要な課題となる。As is well known, the warm forming method is a method of processing a metal material at a temperature of room temperature or higher and a recrystallization temperature or lower. The purpose of raising the temperature to room temperature or higher is to improve the ductility of the metal material and to prevent deformation resistance. And various other purposes such as prevention of deformation after processing due to reduction of residual stress. Therefore, the items required for the lubricant to be applied to temperatures above room temperature are slightly different from those of general lubricants. For example, maintenance of lubricity at high temperature, prevention of degreasing failure of lubricant due to thermal deterioration,
Prevents deterioration of working environment due to gas and smoke generated from the lubricant composition during use, prevention of fire due to ignition,
Preventing galling is an important issue.

It is several times more expensive, and is difficult to use as a lubricant for warm forming except for special cases in terms of cost. Lubricants other than this, such as soybean oil, are easily seized and difficult to degrease later, so synthetic oils (polybutene, silicone oil, etc.)
Decomposes at temperatures above 200 ° C, generating odors and increasing ignitability, deteriorating the working environment. Lubricants in which grease, molybdenum disulfide, mica, etc. are mixed in grease or mineral oil easily generate smoke during use, and seizure and degreasing later become difficult. As described above, few of the conventional aluminum warm-forming lubricants have satisfactory performance.

の問題点の改良を目的とする。SUMMARY OF THE INVENTION Some of the present inventors have previously mentioned, as a warm-forming lubricant, a fatty acid alkali metal salt having 12 to 18 carbon atoms containing 50% or more of a fatty acid having 14 carbon atoms. We have proposed a lubricant for warm working of an aluminum material in which a powder of molybdenum disulfide, graphite, polytetrafluoroethylene, talc or the like having a particle size of 80 μm or less is dispersed in an aqueous solution of 5 to 20% by 25 wt% or less. This warm-working lubricant was excellent in economy and safety, and was superior to conventional products in actions such as work environment measures, seizure prevention during use, and galling prevention. However, compared with general lubricants used at room temperature, discoloration resistance, corrosion resistance, coating properties, etc. are inferior, so sufficient control was required before use. Therefore, the present invention aims to improve these problems of the lubricant for warm working.

The above object has been achieved by developing a lubricant for warm working of aluminum material, which is characterized by adding a solid lubricant after setting to 0.

The higher fatty acids are mainly saturated fatty acids having 10 to 20 carbon atoms, those containing a small amount of unsaturated fatty acids, or natural oil fatty acids such as coconut oil fatty acids and tallow fatty acids. If the fatty acid has less than 10 carbon atoms, the lubricity is inferior, and if it exceeds 20 carbon, the emulsification and dispersibility deteriorates, and uneven coating of the lubricant tends to occur, making it difficult to obtain a good molded product. As fatty acids, lauric acid, palmitic acid,
An example is stearic acid. It is necessary to add 3 to 20 parts by weight of fatty acid. If the amount of fatty acid is less than 3 parts by weight, the lubricity is poor, while if it exceeds 20 parts by weight, the fluidity of the lubricant is lowered, making it difficult to apply the lubricant and impairing its practicality.

For example, tridecyl phosphoric acid ester, 2-ethylhexyl phosphoric acid ester, Nonylphenol phosphate ester, polyoxyethylene tridecyl ether phosphate ester, etc. may be mentioned. If the amount of the phosphate ester is less than 1 part by weight, the effect of preventing discoloration and corrosion is insufficient, and if it exceeds 10 parts by weight, the emulsification dispersibility is impaired.

期保存性に乏しい。As the solid lubricant, one or more solid lubricants such as graphite having a particle size of 80 μm or less, molybdenum disulfide, talc, mica, tetrafluoroethylene resin or boron nitride are used in an amount of 1 part by weight or more and 15 parts by weight or more. Parts or less are dispersed and contained. Since it is difficult to uniformly disperse a solid lubricant having a particle size of more than 80 μm and the cost is high, the particle size should be 80 μm or less. If the blending amount is less than 1 part by weight, the galling resistance is inferior, and if the blending amount is 15 parts by weight or more, the lubricant becomes flaky at high temperature and is likely to fall off, which makes the galling property unstable. As the alkaline compound, hydroxides of alkali metals such as sodium and potassium are preferable in terms of cost and performance. Other alkaline metals have poor solubility of their fatty acid salts, tend to gel easily, and have poor long-term storage stability.

定される。When the pH at a 1% concentration is less than 7.5, the emulsifying dispersibility of the lubricant composition is impaired and the long-term storage stability is deteriorated. On the other hand, when the pH exceeds 9.0, the discoloration preventing effect and the corrosion preventing effect of the phosphoric acid ester are impaired and the object of the present invention cannot be achieved. Therefore, the pH is limited to 7.5 to 9.0.

As the warm forming work, there is a case where a forming die, a tool, and a roll are preheated and a case where a metal material is preheated. In any case, the lubricant of the present invention is preliminarily applied to an aluminum material to be processed. The composition is applied at room temperature, dried and then used for molding. If the surface of the molding die, tool, or roll is applied in advance before heating, the effect is further stabilized.

Among the warm forming lubricants of the present invention, the higher fatty acid alkali salt obtained from the higher fatty acid and the alkali metal compound has a lubricating action even at low temperature, and if a phosphate ester is added to this,
It can be used as a lubricant having an effect of preventing discoloration and corrosion of an aluminum material. However, at a temperature of about 200 ° C. or higher, the lubricity decreases, so it is necessary to blend a solid lubricant.

る。Commercially available alkali metal soaps (higher fatty acid alkali metal salts) have a pH of more than 9 and are compositions that easily corrode aluminum materials when they contain water. In the present invention, however, the pH should be controlled. The discoloration and corrosion of the aluminum material could be effectively suppressed by the effect of the phosphoric acid ester. The reason for this formulation is not clear, but it changes the lubricant composition to a stable viscous state to improve the coating property and at the same time prevents gelation and separation of liquid even when stored for a long period of time, resulting in long-term stability. It is an excellent lubricant for warm working.

For example, as shown in the examples, when the aluminum material is used for processing at a temperature of room temperature or higher and a recrystallization temperature or lower, particularly at a high temperature of 180 ° C. or higher and 350 ° C. or lower, (1) excellent galling resistance and continuous work (2) Excellent lubricity and improved processing limit (3) Excellent seizure resistance, stable degreasing, good product surface quality, (4) Ignition, smoke, odor, etc. The working environment does not deteriorate, and (5) it has excellent long-term stability even during long-term storage, and the dispersion of the solid lubricant is stable. (6) When applied, it does not form a tinsel and has a uniform viscosity Various coating methods such as coating, roll coating and dipping are possible. (7) Even after the lubricant is applied, warm-worked, and left for a long period of time, the aluminum material is not discolored or corroded and can be safely used. There are features such as.
