Description

Aqueous lubricating release agent composition for plastic processing

The present invention relates to a water-based lubrication system that is used when performing plastic working such as carpeting, rolling, drawing, and extrusion of carbon steel, alloy steel, non-ferrous metal, etc., warm or hot. The present invention relates to a release agent composition.

Field background technology

Conventionally, a lubricating release agent for plastic processing of metals and the like that is performed warmly or hotly, and particularly as a lubricant for forging, an oil-dispersed type or a water-dispersed type mainly composed of graphite. O The lubricating oils used in graphite and olive oils have problems such as blackening of the worker or the working environment, impairing health, and oil dispersion. The model has problems such as danger of smoking and ignition.o In addition, there is a risk of malfunction of the motor due to the conductivity of graphite itself. It is pointed out that there is.

In recent years, an environmental management system (· SOI 400 s) has been introduced and studied, and a graphite-based lubricating release agent used for warm and hot forging. In order to solve this problem, a non-graphite lubricating release agent has been developed and put on the market. These non-graphitic lubricating release agents include aromatic carbonates such as phthalates, pyromellitates, and trimellites. Acid salts and aliphatic carboxylate as the main agent. Although the subject is improved, it is a precursor based on graphite, that is, carbonized by the heat held by the mold and the heat provided by the pellets. However, it has been pointed out that lubricating and releasable properties are not as good as those of graphite, and there are limits to their use. Furthermore, since the main component is an organic substance, it has not yet been possible to truly solve health problems such as generation of pyrolysis gas.

On the other hand, a lubricant for warm / hot forging using a non-graphite inorganic material, for example, a synthetic layered structure (monmorillo nitrite) is also used ( JP-A-63-976995) and those using water-soluble glass (JP-A-63-976995). Has been proposed, but these proposals point out that forgings are likely to accumulate in the recesses of the mold and that underfilling is likely to occur. It is not used much, except in special cases. Other lubricants for warm and hot forging using inorganic substances have also been proposed, but in these, the main agent is still graphite.

The present invention eliminates the risk of environmental pollution in graphite, the danger of malfunction of motors, and the danger of smoke and fire in oil-dispersed types. The purpose of the present invention is to provide a hot and hot plastic working of metal using a non-graphite inorganic substance which does not generate meat, and in particular, to provide a water-based lubricating agent for forging. Disclosure of the invention

The inventors of the present invention have conducted intensive studies, and as a result, have found that By using spherical particles as the base material, the minerals overturn the conventional view that they accumulate in recesses, do not accumulate in recesses, and do not cause underfilling. It has been found that a lubrication mechanism (microbearing mechanism) using rotation is formed, and a good forged product is formed. By combining the fine spherical particles with an aqueous adhesive, it was found that the fine spherical particles exhibited an effect of initially adhering the fine spherical particles to the mold surface. However, we have reached the present invention (the first invention).

The inventors of the present invention have further researched and found that by mixing whiskers with these inorganic fine spherical particles and water-based adhesives, the mold surface could be improved. The fact that the movement of the fine spherical particles distributed on the surface is reduced and the lubricating mechanism is further strengthened can be confirmed by combining the inorganic powder having a flaky crystal shape with the mold. The purpose of preventing direct contact of the billet and preventing or reducing the sticking and jumping of the billet is to reduce or prevent metal hydroxide or tying. Mixing inorganic powder with water will cool the mold and prevent sticking and jumping of the billet caused by thermal expansion of the mold. When a lubricating aid is added, the lubricating performance of the fine spherical particles is further improved, and the surface of the forged D¾ surface is reduced.

The average particle size of the inorganic fine spherical particles (hereinafter, referred to as the component (a)) constituting the composition 1 and the composition 2 of the present invention is 0.5. A spherical or nearly spherical inorganic fine particle having a diameter of up to 60 m, preferably 1 to 30 m, and more preferably 1 to 10 μππ can be used. If the average particle size is less than 0.5 m, the particles are likely to aggregate during the formation of the film, making it difficult to obtain lubricity. If it exceeds, the abrasion resistance increases. In other words, the spherical particles settle when diluting and adjusting the lubricant, and do not give good results.

For example, in the case of hot forging using SCM415 material, the deformation resistance is about 50 to 78 MPa, and it is generally about 10 times higher due to formability. The molding load of 500 to 78 OMPa is applied. In the case of hot forging, the temperature of the billet is 65-700 ° C., and the deformation resistance is about 235-27 MPa. Therefore, in order to maintain lubrication performance during forging, the powder must have a compressive strength that is at least greater than the deformation resistance. Required. Therefore, the spherical particles have a compressive strength of more than 98 MPa, preferably more than 2994 MPa, and more preferably more than 39 MPa. It needs to be something. As a result of the examination, the spherical particles having a Mohs hardness of less than 7 cannot withstand the above-mentioned high pressure during forging, and cannot maintain a spherical shape. It has been found . In addition, if the material reacts with the material to be forged, the releasability is impaired. From the above, the spherical particles are preferably made of aluminum, silica, silica-alumina, acid-aluminum titanium having a Mohs hardness of 7 or more. Zirconia and silicon nitride are most suitable, and in the present invention, one or more selected from them can be used. In addition, when the spherical particles are hollow, heat insulation is imparted, and it is possible to prevent underfilling by improving the flowability of the bite, and thereby reducing the thickness of the metal. The prolonged life of the tool (mold) by protection of the mold from thermal impact is achieved.

Constituents of Composition 1 and Composition 2 of the present invention (b) Water system The adhesive (hereinafter, referred to as component (b)) has a function of initially attaching component (a) to the mold surface as described above. The one that can perform its function with as low a concentration as possible is selected. The component (b) may be used in the second invention of the present invention (c) whisker, as in the case of the component (a).

(d) scaly crystal-shaped inorganic powder, (e) inorganic powder having metal hydroxide or binding water, and (f) lubricating aid are added to the mold surface. It has the function of attaching it to the initial stage. In addition, it is necessary to select components (b) that do not cause health hazards and that do not generate harmful gases.

From the above, as the component (b), aqueous epoxy resin resin emulsion, petroleum resin emulsion, polyvinyl alcohol, calco Boxymethylcellulose sodium salt, hydroxymethylcellulose mouth sodium salt, sodium polyacrylate , Sodium isoprene and anhydrous maleic acid copolymer sodium salt, sodium adipate and sodium phosphate are preferred. Yes, one or more of these forces can be used. Of these, water-based epoxy resin resin emulsion, petroleum resin emulsion, 'polyvinyl alcohol, carboxime Cellulose sodium salt and hydroxymethyl cellulose sodium salt can be used at a mold temperature of about 200 ° C. It has excellent performance under the condition that it is cooled, but it is carbonized at high temperature, so if it is used at high temperature, It is desirable to use the one that you want. For sodium polyacrylate, its molecular weight is within the range of 10,000 to 110,000, and its neutrality is within the range of 0.5 to 1.0. It is preferable that the polyacrylic acid be neutralized with sodium hydroxide so as to be in the range, and a high temperature adhesion property is required. In this case, a molecular weight of 200,000 to 110,000 is preferred. If the molecular weight is less than 10,000, it will be decomposed and carbonized by the heat of the mold, and will not function as an adhesive. On the other hand, if the molecular weight exceeds 110,000, the viscosity of the composition becomes too high, and it is not preferable because the composition becomes too gelative.

The above isobutylene monohydrate maleic acid copolymer sodium salt has a molecular weight in the range of 50,000 to 200,000, The isobutylene monohydrate maleic acid copolymer is hydrated with sodium hydroxide so that its neutrality is in the range of 0.5 to 1.0. A neutralized one is preferred. If the molecular weight is less than 50,000, it will be decomposed and carbonized by the heat of the mold and will not function as an adhesive. On the other hand, if the molecular weight exceeds 200,000, the viscosity of the composition becomes too high, which is not preferable because gelling occurs. Further, if the neutrality power is less than 0.5, it is undesirable to exhibit an unpleasant acid odor at the time of work and to reduce the workability. No. If the median degree exceeds 1.0, the sodium will be released, and it will not be desirable for work safety.

(C) Whisker (hereinafter referred to as “component (c)”) constituting the composition 2 of the present invention is composed of the component (a) disposed on the mold surface. It has a function to reduce movement. That is, the component (a) disposed on the mold surface is slightly shifted due to contact with the billet. It moves, but by combining the component (c), the cage

(Figures) to form. As a result, the component (a) often rotates in a fixed position, and the lubricating mechanism is further strengthened. The component (c) preferably has a fiber diameter of 2 / m or less and a fiber length of 10 to 30 m. The fiber diameter is 0.5 to 0.8 times the particle diameter of the component (a), and it is a desirable force. When the fiber diameter exceeds 2 m, the molded product, especially hot forging In the case of construction, it may be damaged, and therefore, those with a length of 2 m or less are preferable. Also, if the fiber length force is less than 10 m, it becomes difficult to fix the component (a), and if it exceeds 30 m, the component (c) is evenly dispersed. This makes it difficult to spray, and when spraying and using a mold release agent, the spraying becomes difficult. As the component (c), from the viewpoint of physical properties such as elasticity, tensile strength, and melting point, potassium titanate, aluminum borate, acid chloride, etc. Titanium and Waste Nite powers are preferred; these powers can be used with one or more of the selected powers.

The composition 2 of the present invention is composed of (d) a non-porous flake-shaped amorphous powder (hereinafter, referred to as component (d)), which is a mold and a vitreous pot. It has a function to prevent direct contact. That is, the component (a) is subjected to a molding load via the billet, and thus, the component (a) is more or less shifted than the position first attached to the mold. Due to the movement, sparse and dense parts can be formed on the mold surface. In the sparse part, there are many opportunities for the mold and the bit to come into direct contact, and it is easy to cause sticking and jumping force. Then, when component (d) is mixed, the mold surface is covered with this component (d), As a result, direct contact between the mold and the bill is prevented, and sticking and jumping-up are less likely to occur. As the component (d), boron nitride, mica, sericite, turquoise, bacillarite, and hydrotalcite are suitable. Thus, one or more of these can be used. The node mouth talcite is also suitable for the following component (e). Therefore, when the node nose site is used as the component (d). In this case, the component (e) described below can be anything other than a hydrorotal site, and the use of the component (e) can be omitted. O can do

Further, the above-mentioned inorganic powder is converted into a sorbitan fatty acid ester, a polyoxyethylene sorbone fatty acid ester and a grease cell. When one or two or more of the selected species are selected from the group consisting of phosphorus and fatty acid esters, the scaly B-shaped inter-layer The results show that the sliding and abrasion resistance of the mold is reduced, the mold is covered more securely, and sticking and jumping are less likely to occur.

Sorbitan fatty acid esters include, but are not limited to, Sorbitan monolaurate, Sorbitan monolumite, Sorbitan monolate Stearate, Sorbitan restorate, Sorbi evening monolate, Sorbitantorioleto, etc. Examples of the oxyethylene sorbitan fatty acid ester include polyoxyethylene sorbitan monolaurate and polyoxyethylene sorbitan fatty acid ester. Schilensolbitan monosparate, polyxylenesolbitan monostearate, polyoxylaten Lensolbitan restorate, polyoxyethylene monolate, polyoxyethylene sonore Evening Glycerin fatty acid esters such as trioleate, monostearic acid monoglyceride and oleic acid type Examples include noglyceride and stearate monooleate monoglyceride.

The inorganic powder containing metal hydroxide or bound water (hereinafter referred to as component (e)) that constitutes composition 2 of the present invention is (e). It has a function to cool the mold. In general, if the mold temperature exceeds 215 ° C, a frosted phenomenon will occur, causing water to splash off and the mold to cool. It is well known that retirement does not go to fullness. For this reason, attempts have been made to quickly form a coating on the surface of the mold to retain water content and to prevent water splashing at least. I came. Since these components, which form the film and form the film, are mainly organic substances, the generation of decomposition gas could not be avoided.

Component (e) is insoluble in water, emits bound water at 200 to 55 ° C, evaporates, and is non-toxic. It is done. The component (e) should be as fine as possible to produce a reaction in a short time and to retain water as a dispersion medium. Particles with a particle size of 10 m or less are desirable. Once the component (e) is distributed, it once adheres to the mold as a fine powder, is decomposed by the heat of the mold, releases and evaporates the water from the sinter, and evaporates. Cool the mold with latent heat. Furthermore, if the bound water comes off, an endothermic reaction of oxide formation occurs at the same time, and the effect is reduced. Cool the mold properly. As the mold cools, it prevents and reduces the sticking and jumping-up of the billet caused by the thermal expansion of the mold, and also reduces the mold. The life of the mold can be extended. As the component (e), there may be mentioned aluminum hydroxide, talcite at the mouth, calcium hydroxide, calcium calcium oxalate, and the like. Hydrates, magnesium hydroxide and magnesium phosphate octahydrate are preferred, and one or more selected from them are preferred. Can be used. As described above, the hydrorotal site is also suitable as the above-mentioned component (d), and therefore, as the component (e). In the case of using a hydrosite, it is possible to use a component other than a hydrorotal site as the above-mentioned component (d). O The use of minute (d) can be omitted o

The lubricating aid (f) constituting the composition 2 of the present invention (hereinafter, referred to as a component (f)) improves the slidability of the billet and improves the formability. It has a function to make it work. As the component (f), sodium phosphates, sodium adipate, sodium maleate, and sodium phthalate It is possible to use one or two or more species selected from among them. Examples of sodium phosphates include sodium dibasic phosphate, sodium tribasic phosphate, sodium triphosphate and sodium hexaphosphate. Sodium sodium phosphate is strong, and sodium phthalates include sodium phthalate, sodium isoflurate, and sodium phthalate. Sodium fluorate is raised. The organic acid sodium is prepared by reacting the organic acid with a stoichiometric amount of sodium hydroxide. You can get what you get.

The composition 1 of the present invention has a component (a) force of 0.1 to 70 weight.

%, Component (b) as an active ingredient in an amount of from 0.02 to 50% by weight, and water in an amount of at least 10% by weight. Yes. Component (a) Strongly less than 0.1% by weight, the required amount cannot be supplied to the mold surface under normal spraying conditions, and sufficient lubrication is effected. If the content exceeds 70% by weight, it becomes difficult to mix other components, and the required characteristics cannot be obtained. In addition, since the composition is in a solid state, work such as dispersion is extremely difficult. Since the component (b) is usually in the form of a solution or an emulsion, the component (b) has a solid component in the solution or the emulsion. Although expressed as an effective component, if the component (b) is less than 0.02% by weight as an active ingredient, the component (a) is adhered to the mold surface. If the amount exceeds 50% by weight, the overall balance of the composition will be lost, and the specified performance will not be achieved, and thermal decomposition will not be achieved. Gas generation will not be ignored. If the hydraulic power is less than 10% by weight, the components cannot be uniformly mixed, and the desired performance cannot be obtained.

The composition 2 of the present invention is composed of the component (a) or 0.1 to 70% by weight, the component (b) as an active ingredient of 0.02 to 50% by weight, and the component (c) power. 0 or less than 20% by weight, the component (d)

0 or less than 40 weights, component (e) force 0 or 2

It is preferred that they are combined such that 0% by weight or less, component (f) is 0 or 20% by weight or less, and the balance is water. Component (a) Vigorously under 0.1% by weight, under normal spray conditions

4 one Cannot supply the required amount to the mold surface, resulting in insufficient lubrication and demolding effects. If the amount exceeds 70% by weight, the other components are not available. It becomes difficult and the required characteristics cannot be obtained. In addition, since the composition becomes a solid, it is very difficult to perform operations such as dispersion. If the component (b) is less than 0.02% by weight as an active ingredient, the component (a) cannot be adhered to the mold surface, and if it exceeds 50% by weight, the total As a result, the balance will not be balanced, the specified performance will not be exhibited, and the generation of pyrolysis gas will not be neglected. If the content of the component (c) exceeds 20% by weight, the performance of the component (a) cannot be sufficiently obtained from the limit of the combination. If the component (d) force exceeds 40% by weight, a thick film is formed on the surface of the mold, resulting in impaired rotational lubrication of the component (a) and sufficient performance. No. If the content of the component (e) exceeds 20% by weight, the risk of peeling off the surface of the film adhered to the mold increases, and it becomes difficult to obtain sufficient lubrication and release properties. . If the content of component (f) exceeds 20% by weight, the heat resistance and adhesion of component (b) will be impaired, and the performance of component (a) will be insufficient. It is difficult to demonstrate. If the water content is less than 10% by weight, the components cannot be uniformly mixed, and the desired performance cannot be obtained. The composition 2 comprises (1) component (a) + component (b) + component (c), (2) component (a) + component (b) + component (d),

(3) component (a) + component (b) + component (e), (4) component (a) + component (b) + component (f), (5) component (a) + component (b) + Component (c) + component (d), component (6) (a) component (b) + component (c) + component (e), (7) component (a) component (b) + component (c) + component (f), (8) component (a) + component ( b) + component (d) + component (e), (9) component (a) + component (b) + component (d) + component (ί), (10) component (a) + component (b) + Component (e) + component (f), (11) component (a) + component (b) + component (c) + component (d) + component (e), (12) component (a) + component ( ) + Component (() + component ((1) + component (), (13) component (a) + component (b) + component (d) + component (e) + component (f) and (1 4) Combining force of component (a) + component (b) + component (c) + component (d) + component (e) + component (ί), which is described in (1), ( 2), (3) and (4) use component (c), component (d), component (e) and component (f) respectively. Thus, the above effects (5), (7), (9) and (10) achieve even better forgeability, and can be applied to forgings having complicated structures. It is more effective, and in the above (6) and (8), the mold temperature rises more easily due to the promotion of mold cooling, and there is much sticking. This is more effective in cases where the mold life is to be prolonged, and the above (11) and (13) require more mold cooling. It is more effective in extending the mold life together with the formability in cases such as deformed forging, and the above (1 2) and (14) are complex deformed. More effective when overall performance is required, such as large or deep drawn forgings

6 Compositions 1 and 2 of the present invention are usually prepared by mixing and mixing the above components and water in the proportions described above, and then mixing. In particular, it is desirable to use a stirrer equipped with high-speed rotating blades and forcibly mix and stir the mixture.

Compositions 1 and 2 of the present invention may contain, as necessary, a surfactant, a dispersant, an extreme pressure additive, a metal corrosion inhibitor, a preservative, an antifoaming agent, etc., in addition to the above components. It cannot be overemphasized that it is possible to mix various components of the above. As the surfactant, nonionic surfactants and anionic surfactants, particularly nonionic surfactants, are preferred. As the nonionic surfactant, a modified silicone is particularly preferred.

The composition 1 and the composition 2 of the present invention having the above-mentioned composition are forged, rolled, drawn, and extruded from a carbon steel, an alloy steel, a non-ferrous metal, etc. under warm or hot conditions. It can be used as a lubricating agent for plastic processing such as, but it is especially effective as a lubricating agent for warm and hot forging. . When used as a lubricating release agent for warm / hot forging, the method of use is the same as the conventional lubricating release agent for warm / hot forging. In use, it is usually diluted with water. The dilution ratio with water depends on the specific surface area of the component (a) to be used, the surface area of the mold, the concentration of the component (a) in the composition, the length of the film in contact with the film, and the lubrication. Although it differs depending on the release agent liquid spray amount, etc., it can usually be increased to 40 to 100 times. This is because the dilution ratio of conventional graphite-based and non-graphite-based lubricating agents is 10 to 30 times. It is effective to increase the size. With conventional graphite-based swellable agents, it was necessary to gradually change the dilution ratio so that it would be suitable for use in the field when used. Such a composition does not require such a thorough adjustment of the dilution ratio. The metal materials to be processed to which the composition 1 and the composition 2 of the present invention are applied include structural carbon steel, case hardening steel, alloy case hardening steel, and non-ferrous metal. It can be used widely and is not restricted.
