Definitions
- the present invention relates to a water-based lubricating coating agent which is applied when plastic working is performed to various types of metal materials, and a metal material with a coating film formed by applying the agent onto the metal material surface and drying the agent.
- chemical conversion coating films are common which are composite coating films using phosphate coating films and soaps.
- the chemical conversion coating films have problems such as by-products associated with reactions with metal materials, effluent treatments of water such as water rinsing, and large spaces for the treatments, and in recent years, environmentally conscious water-based dry-in-place type one-pack lubricants have been developed.
- Patent Literature 1 discloses a water-based lubricating coating agent for plastic working of metal materials, characterized in that the composition of (A) water-soluble inorganic salt and (B) a wax is dissolved or dispersed in water, and the solid content mass ratio (B)/(A) falls within the range of 0.3 to 1.5, and a method of forming a coating film therefrom.
- Patent Literature 2 discloses a water-based lubricating coating agent for plastic working of metal materials, which contains an alkali metal borate (A), characterized in that the alkali metal borate (A) includes a lithium borate, the molar ratio of lithium to all of the alkali metals is 0.1 to 1.0 in the alkali metal borate (A), and the molar ratio (B/M) between a boric acid B and an alkali metal M is 1.5 to 4.0 in the alkali metal borate (A), and a method of forming a coating film therefrom.
- This technique is supposed to suppress the crystallization of the coating film, which is caused by moisture absorption of the coating film, thereby making it possible to form coating films with not only workability but also high corrosion resistance.
- Patent Literature 3 discloses a non-phosphorus aqueous lubricant for plastic working, which contains A component: inorganic solid lubricant, B component: wax, and C component: water-soluble inorganic metal salt, characterized in that the solid content mass ratio (A component/B component) is 0.1 to 5 between the A component and the B component, and the solid content mass ratio (C component/(A component + B component + C component)) of the C component is 1 to 30% to the total amount of the A component, B component, and C component.
- This technique is directed to a lubricant containing no phosphorus, and supposed to be able to achieve corrosion resistance comparable to that of chemical conversion coating films.
- Patent Literature 4 discloses a water-based lubricating coating agent including a water-soluble inorganic salt (A), a lubricant (B) selected from molybdenum disulfide and graphite, and a wax (C) dissolved or dispersed in water, where the ratio (B)/(A) is 1.0 to 5.0 in terms of solid content weight ratio, and the ratio (C)/(A) is 0.1 to 1.0 in solid content weight ratio, and a method of forming a coating film therefrom.
- This technique is supposed to achieve the same level of high workability as that of chemical conversion coating films by blending a conventional water-based lubricating coating agent with molybdenum disulfide or graphite.
- Patent Literature 6 discloses a lubricant composition
- a lubricant composition comprising alkali metal borates and alkali metal sulfates as essential components and furthermore comprising alkali metal salts of fatty acids, alkaline earth metal salts of fatty acids, a solid lubricant, a water-soluble thermoplastic resin and optionally sodium silicate.
- Patent Literature 7 discloses a metal material for plastic working, whereby the surface thereof is equipped with a lubricating film that contains sodium metaborate (A1) and sodium metasilicate (A2), zinc stearate (B), calcium hydroxide (C) and a 1-dodecene/maleic acid anhydride copolymer (D).
- A1 sodium metaborate
- A2 sodium metasilicate
- B zinc stearate
- B calcium hydroxide
- D 1-dodecene/maleic acid anhydride copolymer
- the inventors have found, as a result of earnestly studying in order to solve the problems mentioned above, that the formation of a coating film by combining a water-soluble silicate and a specific water-soluble inorganic salt at a specific ratio provides high corrosion resistance (in particular, long-term rust prevention property), workability and adequate film removability which have not been able to be achieved in any way by the single components, thereby achieving the present invention.
- the present invention (1) is a water-based lubricating coating agent characterized in that a water-soluble silicate (A) having a solubility of at least 1 g in 100 g of water at 25°C and a water-soluble inorganic salt (B) having a solubility of at least 1 g in 100 g of water at 25°C, which is a tungstate, are blended such that the solid content mass ratio (B)/(A) falls within the range of 0.7 to 25, wherein
- A water-soluble silicate
- B water-soluble inorganic salt
- the present invention (2) is a metal material with a lubricating coating film of 0.5 to 40 g/m2 as coating weight, which is formed on a metal material surface by applying and drying the water-based lubricating coating agent for plastic working according to the invention (1), which is excellent in plastic workability.
- the use of the water-based lubricating coating agent according to the present invention provides a lubricating coating film which is excellent in corrosion resistance, workability and film removability in practical use.
- the agent is significantly superior as compared with conventional water-based lubricating coating films in that all of these performances have a level comparable or superior to those of chemical conversion coating films.
- Metal materials where the coating film with the previously mentioned great characteristics is formed on the metal material surfaces can be obtained by applying and drying the water-based lubricating coating agent according to the present invention.
- Fig. 1 is indications of the evaluation in an upsetting-ball ironing tribo-test (seizure resistance evaluation).
- a water-based lubricating coating agent according to the present invention is obtained by blending a water-soluble silicate (A) (hereinafter, referred to as a silicate (A)) and a water-soluble inorganic salt (B) (hereinafter, referred to as an inorganic salt (B)) , which is a tungstate, such that the solid content mass ratio (B)/(A) falls within the range of 0.7 to 25.
- the blend in the range can form a coating film with high corrosion resistance and workability and adequate film removability which have not been able to be achieved by the silicate (A) or inorganic salt (B) itself.
- water-soluble in the Claims and the Specification means that the solubility in water at room temperature (25°C) ⁇ the mass (g) of a solute dissolved in 100 g of water ⁇ is at least 1 g, and preferably 10 g or more.
- the inorganic salt (B) When the silicate (A) and the inorganic salt (B) are combined to provide a coating film, the inorganic salt (B) will be incorporated finely and homogeneously in a network structure formed by the silicate (A). As a result, the fragile coating film of the silicate (A) is made flexible to improve the workability.
- the incorporation of the inorganic salt (B) in the network structure of the silicate (A) makes the coating film denser, thereby enhancing the barrier performance, and thus improving the corrosion resistance (in particular, long-term rust prevention property).
- the network structure of the silicate (A) is appropriately blocked by the inorganic salt (B), thereby improving the film removability.
- the ratio between the silicate (A) and the inorganic salt (B) is important for delivering the performances mentioned above.
- the performances are delivered at a solid content mass ratio (B)/(A) within the range of 0.7 to 25, but preferably in the range of 0.9 to 10.0, and more preferably 1.1 to 3.0.
- the ratio (B)/(A) below 0.7 results in failure to achieve sufficient corrosion resistance and workability, and also provides a coating film which is inferior in film removability. This is due to a rigid network structure formed by the relatively increased amount of the silicate.
- the ratio (B)/(A) in excess of 25 results in failure to achieve sufficient corrosion resistance, and also results in a coating film which is inferior in adhesion and uniformity. This is due to the fact that the relatively excessively small amount of the silicate results in failure to build an adequate network structure, thereby degrading the barrier performance, and degrading the adhesion and uniformity of the coating film.
- the corrosion resistance is significantly improved by the formation of a passivation film that has a self-repairing function unique to tungsten.
- stable corrosion resistance can be achieved even when the coating film becomes defective, e.g., due to steels in contact with each other. For this reason, stable corrosion resistance is likely to be produced even in the case of processing large amounts of materials simultaneously, such as mass processing and coil processing of wire rods with the use of barrels for use in lubricating agents for cold forging.
- silicate (A) for use in the coating agent according to the present invention examples include, for example, lithium silicates, sodium silicates, and potassium silicates. These may be used singly, or two or more thereof may be combined. In particular, it is preferable to use lithium silicates and/or sodium silicates.
- Tungstates include, for example, lithium tungstates, sodium tungstates, potassium tungstates, and ammonium tungstates. These may be used singly, or two or more thereof may be combined.
- the resin component (C) is blended for purpose of providing binder action, improving the adhesion between the base material and the coating film, providing leveling property by thickening action, stabilizing the dispersing component, and improving barrier property.
- the resin component (C) which has such functions and properties is at least one selected from the group consisting of vinyl resins, acrylic resins, epoxy resins, urethane resins, phenolic resins, cellulose derivatives, polymaleic acid, polyolefin, and polyester.
- the resin component (C) used herein has a film formation property and is typically supplied in a water-soluble or water-dispersion state. These may be used singly, or two or more thereof may be combined.
- the solid content mass ratio (C)/ ⁇ (A) + (B) ⁇ of the resin component (C) to the silicate (A) and the inorganic salt (B) is 0.01 to 3, and preferably 0.1 to 1.5.
- the ratio of less than 0.01 may fail to provide binder action, improve the adhesion between the base material and the coating film, provide the leveling property by thickening action, stabilize the dispersing component, improve the barrier property, or the like as expected for the resin component (C), whereas in the case of the ratio in excess of 3, the amount of the silicate and inorganic salt may be relatively reduced, thereby making it impossible to sufficiently exhibit high corrosion resistance and workability.
- the lubricant (D) itself has lubricity and causes slippage, and has the function of reducing a frictional force between a die for processing and a material to be processed.
- the increased frictional force during plastic working increases the working energy, generates heat, causes seizure, or the like, but when the water-based lubricating coating agent according to the present invention includes the lubricant (D), the increase in frictional force will be suppressed.
- the lubricant (D) which has such functions and properties is at least one selected from the group consisting of waxes, polytetrafluoroethylene, fatty acid soaps, fatty acid metal soaps, fatty acid amides, molybdenum disulfide, tungsten disulfide, graphite, melamine cyanurate, amino acid compounds of layered structure, and layered clay minerals.

- these layered clay minerals may be subjected to an organic treatment, thereby introducing an organic denaturant between layers.
- the organic treatment is carried out in accordance with a method of introducing the organic denaturant with the interlayer distance increased by causing the layered clay minerals to swell with water.
- the organic denaturant is an alkylamine or an alkyl quaternary ammonium salt which adsorbs in between layers to form a strong bond, and specific examples thereof include stearyldimethylamine, distearylamine, distearyldimethylamine, stearyltrimethylammoniumchloride, and distearyldimethylammoniumchloride.

- the ratio (D)/ ⁇ (A) + (B) ⁇ of less than 0.01 results in failure to sufficiently exert the friction-reducing effect expected for the lubricant (D), whereas in the case of the ratio in excess of 6, the relatively decreased amount of the silicate (A) and inorganic salt (B) may make it impossible to sufficiently exhibit high corrosion resistance and workability.
- a viscosity modifier can be blended for the purpose of providing leveling property and thixotropy in order to ensure an evenly applied state when the lubricant is applied to the base material.

- Wire drawing was carried out by drawing a steel wire of ⁇ 3.2 mm through a die of ⁇ 2.76.
- Missile C40 from Matsuura Industry Co., Ltd. was used as a dry lubricant.
- the dry lubricant was put in a die box immediately before drawing the material so as to naturally adhere to the material.
- the evaluation was made from seizure of the test material and the residual amount of the lubrication film after the wire drawing. It is to be noted that the coating amount after the wire drawing was obtained from the mass difference between before and after removal by removing the coating film with the use of the following film remover.
- Examples 17 to 26, 29 to 39 and 42, Reference Examples 27, 28, 40 and 41 and Comparative Examples 10 to 28 were evaluated for corrosion resistance.
- the wire rod subjected to the wire drawing test mentioned above was exposed to indoors for 3 months in an open atmosphere in summer, thereby observing the degree of rust. It has been determined that the corrosion resistance is more inferior as the rusted area is larger.
- the use of the water-based lubricant according to the present invention can achieve a balance between high workability and corrosion resistance. Furthermore, the lubricating coating film after the processing with the cleaner is also favorably removed. Accordingly, the present invention has an extremely great deal of potential in industry.
