Description
Technical Field
The present invention relates to a heat treatment oil composition.
Background
In a metal material such as a steel material, heat treatment such as quenching, tempering, annealing, and normalizing is performed for the purpose of improving the properties thereof. Among these heat treatments, quenching is a treatment in which a heated metal material is immersed in a coolant to transform into a predetermined quenched structure, and the quenched material becomes very hard by this quenching. For example, if a heated steel material in an austenitic state is immersed in a coolant and cooled at an upper critical speed or higher, transformation to a quenched structure such as martensite is possible.
As the coolant, an oil-based or water-based heat treatment agent is generally used. If the quenching of a metal material using an oil-based heat treatment agent (heat treatment oil) is described, the heated metal material is usually cooled in 3 stages when it is put into the heat treatment oil as a coolant. Specifically, the heat treatment oil is (1) a 1 st stage (vapor film stage) in which the metal material is covered with a vapor film of the heat treatment oil, (2) a 2 nd stage (boiling stage) in which the vapor film is broken and boils, and (3) a 3 rd stage (convection stage) in which the temperature of the metal material is not higher than the boiling point of the heat treatment oil and heat is lost by convection. In each stage, the cooling rate is different depending on the ambient atmosphere of the metal material, and the cooling rate in the 2 nd stage (boiling stage) is the highest.
In general, in the heat-treated oil, the cooling rate sharply increases when the phase shifts from the vapor film phase to the boiling phase. When the metal material is not a simple planar shape, a vapor film stage and a boiling stage are likely to be mixed on the surface of the metal material. When the mixing occurs, a great temperature difference occurs on the surface of the metal material due to the difference in cooling rate between the vapor film stage and the boiling stage. Then, due to this temperature difference, thermal stress and strain stress are generated, and strain is generated in the metal material. Therefore, in the heat treatment, particularly quenching, of a metal material, it is important to select a heat treatment oil suitable for the heat treatment conditions, and if this selection is not appropriate, strain may occur in the metal material and sufficient quenching hardness may not be obtained.
Heat treatment oil was measured in JIS K2242: 2012 are classified into 1 to 3 groups, and 1 and 2 oils of 1 group and 1 and 2 oils of 2 group and 2 oil are used for quenching.
JISK 2242: 2012, the number of cooling seconds of 800 to 400 ℃ is defined as a measure of cooling performance, 5.0 seconds or less in class 1, 4.0 seconds or less in class 1, 5.0 seconds or less in class 2, and 6.0 seconds or less in class 2.
The shorter the cooling seconds, the higher the cooling performance, and the metal material becomes hard. Generally, the hardness of a quenched metal has a trade-off relationship with strain, with harder metals having greater strain.
Industrially, the number of seconds at 300 ℃ is also used as an index for the cooling property of the oil agent. 300 ℃ seconds refers to seconds per JISK 2242: 2012 test method for cooling performance, and the cooling time from 800 ℃ to 300 ℃ of the cooling curve.
As an index indicating the cooling property of the oil agent, the number of seconds (characteristic number of seconds; vapor film length) from the start of the vapor film stage to the temperature (characteristic temperature) at which the end is reached is also used. In general, if the vapor film stage is longer, the time during which the vapor film stage and the boiling stage are mixed together tends to be longer, and the strain tends to be larger. JISK 2242: 2012, the characteristic temperature is defined as class 1 No. being defined as 480 ℃ or higher, class 1 No. 2 being defined as 580 ℃ or higher, class 2 No. 1 being defined as 500 ℃ or higher, class 2 No. being defined as 600 ℃ or higher.
The type 1 oil and the type 2 oil correspond to cold oil used at low oil temperature, the type 2 oil 1 oil corresponds to semi-hot oil used at higher oil temperature, and the type 2 oil corresponds to hot oil used at high oil temperature.
The user selects the quenching oil based on the above-described index in order to obtain the target hardness and strain. For example, the above-mentioned group 2 No. 1 oil is widely used in quenching of automotive gear parts and the like where strain is a problem. The reason for this is that the group 1 oil has too high hardness depending on the component, in addition to large strain. The reason for this is that the type 2 oil is insufficient in hardness although the strain is small.
However, parts such as transmissions and speed reducers for automobiles are mass-produced in almost all cases, and so-called concentrated quenching is performed in which a large number of processed products are stacked on 1 pallet and quenched together. In this case, there is a problem that variations occur in cooling performance depending on the position where the stacked components are mounted, and variations occur in hardness and strain of each component. For example, the hardness of the member attached to the lower portion is high, and the hardness of the member attached to the upper portion is low. In view of the above, techniques of patent documents 1 to 4 have been proposed.
Patent document 1 proposes a heat treatment oil composition having cooling performance comparable to that of the above-mentioned group 2 No. 1 oil, and reducing variations in cooling performance during concentrated quenching. Specifically disclosed is a heat-treated oil composition characterized by containing a mixed base oil which is characterized by containing 5 mass% or more and less than 50 mass% of a low-boiling base oil having a 5% distillation temperature of 300 ℃ or more and 400 ℃ or less and more than 50 mass% and 95% or less of a high-boiling base oil having a 5% distillation temperature of 500 ℃ or more.
Patent document 2 proposes a heat-treating oil composition containing 50 to 95 mass% of a total composition and having a kinematic viscosity at 40 ℃ of 5mm260mm of more than s2A base oil having a 40 ℃ kinematic viscosity of 300mm of 5 to 50 mass% based on the total amount of the composition2The base oil and the alpha-olefin copolymer having a viscosity of at least s can reduce variations in cooling performance during concentrated quenching.
Patent document 3 proposes a heat treatment oil composition which has cooling performance comparable to that of the above-mentioned group 2 oil No. 1 and which reduces variations in cooling performance during concentrated quenching, the heat treatment oil composition containing a petroleum resin as a vapor film breaking agent and having a characteristic number of seconds of 1.00 second or less and a 300 ℃ number of seconds of 6.00 seconds or more and 14.50 seconds or less.
Patent document 4 proposes a heat treatment oil composition capable of exhibiting high cooling performance, which has kinematic viscosity at 40 ℃Degree of 4mm2More than s and 20mm2An alkenyl or alkyl succinimide is blended in the base oil with a flow rate of less than s.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail. The present invention is not limited to the following embodiments, and can be implemented by being arbitrarily changed within a scope not departing from the gist thereof.
The present invention relates to a heat-treated oil composition comprising (a) a base oil and (B) a vapor film-breaking agent. The heat treatment oil composition of the present invention is prepared according to JIS K2242: 2012 for the cooling curve, i.e., the cooling time from 800 ℃ to 300 ℃ in the cooling curve, i.e., the number of seconds at 300 ℃ is less than 6 seconds, and the component (B) contains a petroleum resin.
The heat treatment oil composition of the present invention is excellent in the balance of cooling performance, quenching hardness, and quenching strain.
The heat treatment oil compositions described in patent documents 1 to 3 (jp 2007 & 009238 a, jp 2013 & 194262 a, and jp 2016 & 151054 a) have a long cooling time and reduce quenching strain, but are sometimes applied to conveying members (e.g., gears and bearings) such as automobile parts, etc., because the quenching hardness is insufficient, and further hardness increase is required. On the other hand, the heat treatment oil composition described in patent document 4 (jp 2010-229479 a) has a short cooling time and high quenching hardness, but has a large quenching strain and is difficult to apply to a component having a complicated shape or the like. There is still a demand for a heat treatment oil composition that can achieve both high quench hardness and reduced quench strain.
The heat treatment oil composition of the preferred embodiment can achieve both high quench hardness and reduced quench strain. The heat treatment oil composition of the present embodiment can be suitably used for transportation members (e.g., gears and bearings), particularly large-sized members, such as automobile parts.
Hereinafter, each component will be described in detail. The upper limit and the lower limit of the numerical range described in the present specification may be arbitrarily combined. For example, when "A to B" and "C to D" are described, "A to D" and "C to B" are also included in the scope of the present invention. In addition, the numerical range "lower limit value to upper limit value" described in the present specification means not lower than the lower limit value but not higher than the upper limit value.
[ component (A): base oil ]
The base oil is not particularly limited, and any of mineral oils and synthetic oils used as base oils for heat treatment oils can be suitably selected and used.

[ component (B): vapor film-rupturing agent
The heat-treating oil composition comprises a petroleum resin as a vapor film disruptor. By using the petroleum resin, the vapor film stage can be shortened, and the vapor film stage and the boiling stage can be made difficult to be mixed on the surface of the metal material. This makes it possible to prevent variations in cooling performance (variations in hardness and strain) of each member during quenching. In addition, even in the case of a component having a complicated shape, variations in cooling performance of each component part can be made less likely to occur, and therefore, strain of each component can be suppressed. Further, by containing the petroleum resin, the characteristic seconds in the initial stage of the heat treatment can be shortened, and thus excellent cooling performance can be provided from the initial stage of the heat treatment. In addition, by using the petroleum resin, it is possible to suppress a change with time in cooling performance of the heat treatment oil composition when the heat treatment of the metal material is repeated. Therefore, by using the petroleum resin, the life of the heat-treating oil composition can be extended. The reason why the petroleum resin can exhibit these effects is considered to be the thermoplasticity of the petroleum resin and the excellent solubility in the base oil.
The petroleum resin is obtained by polymerizing or copolymerizing 1 or 2 or more unsaturated compounds selected from the group consisting of aliphatic olefins or aliphatic diolefins having 4 to 10 carbon atoms and aromatic compounds having 8 or more carbon atoms and an ethylenically unsaturated bond, which are obtained as a by-product in the production of olefins such as ethylene by thermal decomposition of petroleum such as naphtha. For example, the petroleum resin is a resin obtained by copolymerizing an unsaturated compound containing dicyclopentadiene and an aromatic compound, which is a C5 fraction as a main raw material (dicyclopentadiene-aromatic copolymer petroleum resin).
These petroleum resins can be roughly classified into, for example, "aliphatic petroleum resins" obtained by polymerizing aliphatic olefins and/or aliphatic diolefins, "aromatic petroleum resins" obtained by polymerizing aromatic compounds having an ethylenically unsaturated bond, and "aliphatic-aromatic copolymerized petroleum resins" obtained by copolymerizing aliphatic olefins and/or aliphatic diolefins with aromatic compounds having an ethylenically unsaturated bond.
Examples of the aliphatic olefins having 4 to 10 carbon atoms include butene, pentene, hexene, heptene and the like. Examples of the aliphatic diolefins having 4 to 10 carbon atoms include butadiene, pentadiene, isoprene, cyclopentadiene, dicyclopentadiene, and methylpentadiene. Examples of the aromatic compound having an ethylenically unsaturated bond and having 8 or more carbon atoms include styrene, α -methylstyrene, β -methylstyrene, vinyltoluene, vinylxylene, indene, methylindene, and ethylindene.
Further, the raw material compounds of the petroleum resin do not need to be all by-products in the production of olefins by thermal decomposition of petroleum such as naphtha, and chemically synthesized unsaturated compounds may be used. For example, "dicyclopentadiene-based petroleum resin" obtained by polymerization of cyclopentadiene, dicyclopentadiene (DCPD); "dicyclopentadiene-aromatic-copolymerized petroleum resins" (for example, dicyclopentadiene-styrene-based petroleum resins) obtained by copolymerizing cyclopentadiene and dicyclopentadiene with an aromatic compound having an ethylenically unsaturated bond.
In the present specification, the petroleum resin includes a hydrogenated petroleum resin, a modified petroleum resin, and other petroleum resin derivatives.
The hydrogenated petroleum resin is obtained by adding a hydrogen atom to the petroleum resin. All or part of the double bonds in the molecule are hydrogenated by hydrogenation. Thus, the hydrogenated petroleum resin may be a fully hydrogenated petroleum resin or a partially hydrogenated petroleum resin. When a partially hydrogenated resin is used, the resin is excellent in cooling property and has a low softening point, and therefore, the resin can be easily produced.
Examples of the modified petroleum resin include acid-modified petroleum resins obtained by modifying the petroleum resin with an acidic functional group represented by a carboxylic acid or the like; the acid-modified petroleum resin is obtained by reaction modification of a compound such as alcohol, amine, alkali metal, alkaline earth metal, or the like. Examples of the acid-modified petroleum resin include a carboxylic acid-modified petroleum resin obtained by modifying a petroleum resin with an unsaturated carboxylic acid or an unsaturated carboxylic acid anhydride, and an acid anhydride-modified petroleum resin. Examples of the unsaturated carboxylic acid include unsaturated monocarboxylic acids such as acrylic acid and methacrylic acid; unsaturated polycarboxylic acids such as maleic acid, fumaric acid, itaconic acid, and citraconic acid; partial esters of unsaturated polycarboxylic acids such as monomethyl maleate and monoethyl fumarate, and examples of the unsaturated carboxylic acid anhydride include unsaturated polycarboxylic acid anhydrides such as maleic anhydride and itaconic anhydride.
As the petroleum resin, synthetic resins can be used, and commercially available products can also be used.
The petroleum resins may be used alone or in combination of 2 or more.
In one embodiment, the petroleum resin is at least 1 selected from the group consisting of an aliphatic petroleum resin, an aromatic petroleum resin, an aliphatic-aromatic copolymer petroleum resin, a dicyclopentadiene petroleum resin, and a dicyclopentadiene-aromatic copolymer petroleum resin, and a hydrogenated petroleum resin and a modified petroleum resin thereof.
Among these, as the petroleum resin, an aliphatic-aromatic copolymerized petroleum resin, a hydrogenated aliphatic-aromatic copolymerized petroleum resin, and particularly a hydrogenated aliphatic-aromatic copolymerized petroleum resin are preferable in terms of shortening the characteristic seconds. For example, the petroleum resin is a hydrogenated petroleum resin of dicyclopentadiene-aromatic copolymerization type.
The number average molecular weight (Mn) of the petroleum resin is preferably 200 to 5000, more preferably 250 to 2500, and still more preferably 300 to 1500 in terms of characteristic seconds. Here, the number average molecular weight (Mn) can be measured by the VPO method.

The "softening point" in the present specification can be determined by JISK 2207: 2006 by the ring and ball method. By setting the softening point to 40 ℃ or higher, it is possible to make it more difficult for variations in cooling performance (variations in hardness and strain) of each member to occur during quenching, and also, in the case of a member having a complicated shape, it is possible to make it difficult for variations in cooling performance of each member portion to occur, and thus, it is possible to suppress strain of each member. Further, by setting the softening point to 40 ℃ or higher, the change with time of the cooling performance (increase with time of the characteristic seconds and decrease with time of the kinematic viscosity) when the heat treatment is repeated can be further suppressed, and the characteristic seconds in the initial stage of the heat treatment can be shortened. Further, by setting the softening point of the petroleum resin to 150 ℃ or lower, the stickiness of the surface of a workpiece such as a metal material after the workpiece is cooled by heat treatment of the oil composition can be reduced. The softening point of the petroleum resin can be adjusted by the degree of polymerization, the modifying component, and the degree of modification of the petroleum resin.
When 2 or more kinds of materials are used as the petroleum resin, all the materials are preferably in the above softening point range.

As the hue of petroleum resin, according to JISK 6901: the Hazen color measured by 2008 is preferably 50 or less, more preferably 40 or less, and further preferably 30 or less.

The content of the petroleum resin is preferably 0.1 to 90% by mass based on the total amount of the composition. If the content is 0.1% by mass or more, the cooling performance can be improved. The petroleum resin generally has a high viscosity, and the viscosity of the composition tends to increase as the amount thereof is increased. If the content is 90% by mass or less, it is preferable in view of an appropriate viscosity. The content of the petroleum resin is more preferably 0.1 to 60% by mass, still more preferably 1 to 35% by mass, still more preferably 2 to 25% by mass, and particularly preferably 4 to 15% by mass, from the viewpoint of viscosity and cooling performance.

Examples of other vapor film-breaking agents include terpene resins, terpene resin derivatives, rosin derivatives, and the like.

[ component (D): metal-based detergent dispersant
