Definitions
- This invention relates to the use of a compound obtainable by reacting at least one member selected from the group consisting of polyalkylenepolyamines and polyalkyleneimines each containing 3 to 200 nitrogen atoms with at least one member selected from the group consisting of fatty acid compounds, glycidyl ether compounds and epoxy compounds as a cold rolling oil additive and the use of the above described compound in a cold rolling oil composition.
- the cold rolling oil in prevalent use today is generally based on, as the lubricating oil component, an animal or vegetable oil, a mineral oil, a fatty acid ester or the like and contains, as supplemental components, a rust inhibitor, high-pressure agent, oil improving agent, antioxidant, antifoam and/or other auxiliary agents.
- Such cold rolling oil is emulsified with an emulsifying agent into an O/W emulsion, which is then fed to the roll assembly of the mill generally at a concentration of about 1 to 20 percent.
- high-speed rolling and mass production have been implemented and there is consequently a demand for rolling oil with improved lubricating property, workability and amenability to effluent disposal.
- the prior art cold rolling oil incorporating the conventional emulsifier controls rolling lubricity by adjusting the type and addition level of emulsifier to thereby increase or decrease the quantity of oil (plateout) that will be deposited on the surface of rolling work, with the result that the amount of plateout and the stability of the circulating emulsion cannot be reconciled.
- the higher the stability of the emulsion the smaller is the amount of plateout on the rolling work, thus leading to an insufficiency of lubrication.
- the stability of the emulsion is sacrificed so that various troubles are encountered while the emulsion is circulated.
- US-A-4 705 643 relates to a lubricating oil composition
- a detergent additive which is the hydrolised reaction product of an aliphatic branch chain carboxylic acid of 16 to 20 carbon atoms and a polyamine of at least 3 amine groups.
- the lubricating oil composition disclosed therein is used in the field of fuel/oil mixtures, specifically in 2 stroke cycle internal combustion engines.
- a composition comprising alone or in combination with each other polyamides obtained by reacting specific polyalkylenediamines with specific fatty acids, such as linolec acid is disclosed in FR-A 1 318 311.
- This composition can be used in lubricants and fuels for combustion motors.
- This invention relates, in one aspect, to the use as a cold rolling oil additive of a compound obtainable by reacting at least one member of the group consisting of polyalkylenepolyamines and polyalkyleneimines each containing 3 to 200 nitrogen atoms with at least one member of the group consisting of fatty acid compounds, glycidyl ether compounds and epoxy compounds and, in another aspect, to the use of the above described compound in a cold rolling oil composition, which has excellent lubricating capability, emulsion stability and annealing process antifouling property and assures the utmost cleanliness of rolling mill equipment.

Description
- This invention relates to the use of a compound obtainable by reacting at least one member selected from the group consisting of polyalkylenepolyamines and polyalkyleneimines each containing 3 to 200 nitrogen atoms with at least one member selected from the group consisting of fatty acid compounds, glycidyl ether compounds and epoxy compounds as a cold rolling oil additive and the use of the above described compound in a cold rolling oil composition.
- The cold rolling oil in prevalent use today is generally based on, as the lubricating oil component, an animal or vegetable oil, a mineral oil, a fatty acid ester or the like and contains, as supplemental components, a rust inhibitor, high-pressure agent, oil improving agent, antioxidant, antifoam and/or other auxiliary agents. Such cold rolling oil is emulsified with an emulsifying agent into an O/W emulsion, which is then fed to the roll assembly of the mill generally at a concentration of about 1 to 20 percent. On the other hand; with the recent advance of rolling technology, high-speed rolling and mass production have been implemented and there is consequently a demand for rolling oil with improved lubricating property, workability and amenability to effluent disposal.
- Under the circumstances, the prior art cold rolling oil incorporating the conventional emulsifier controls rolling lubricity by adjusting the type and addition level of emulsifier to thereby increase or decrease the quantity of oil (plateout) that will be deposited on the surface of rolling work, with the result that the amount of plateout and the stability of the circulating emulsion cannot be reconciled. Stated differently, the higher the stability of the emulsion, the smaller is the amount of plateout on the rolling work, thus leading to an insufficiency of lubrication. On the other hand, if it is attempted to increase the amount of plateout, the stability of the emulsion is sacrificed so that various troubles are encountered while the emulsion is circulated. Furthermore, the iron particles produced in the course of cold reduction find their way into this unstable emulsion so that scums tend to be attached to the cold-rolled steel plate to adversely affect the subsequent washing and annealing processes. Furthermore, the scums attach themselves to the rolls and the equipment around the rolls to jeopardize the work environment and interfere with workability. To overcome these disadvantages, a variety of cold rolling oil compositions have been proposed (for example, Japanese Patent Publication No. 62-14599 and Japanese Kokai Patent Publication No. 62-121792). However, these compositions are invariably deficient in annealing process antifouling performance and in the assurance of cleanliness of the rolling mill equipment, thus being of no great field utility.
- US-A-4 705 643 relates to a lubricating oil composition comprising a detergent additive, which is the hydrolised reaction product of an aliphatic branch chain carboxylic acid of 16 to 20 carbon atoms and a polyamine of at least 3 amine groups. The lubricating oil composition disclosed therein is used in the field of fuel/oil mixtures, specifically in 2 stroke cycle internal combustion engines.
- A composition comprising alone or in combination with each other polyamides obtained by reacting specific polyalkylenediamines with specific fatty acids, such as linolec acid is disclosed in FR-A 1 318 311. This composition can be used in lubricants and fuels for combustion motors.
- This invention relates, in one aspect, to the use as a cold rolling oil additive of a compound obtainable by reacting at least one member of the group consisting of polyalkylenepolyamines and polyalkyleneimines each containing 3 to 200 nitrogen atoms with at least one member of the group consisting of fatty acid compounds, glycidyl ether compounds and epoxy compounds and, in another aspect, to the use of the above described compound in a cold rolling oil composition, which has excellent lubricating capability, emulsion stability and annealing process antifouling property and assures the utmost cleanliness of rolling mill equipment.

- The compound to be used as a metal cold rolling oil additive is a compound obtainable by reacting at least one member selected from the group consisting of the aforementioned polyalkylenepolyamines and polyalkyleneimines each containing 3 to 200 nitrogen atoms with at least one member selected from the group consisting of the aforementioned fatty acid compounds, glycidyl ether compounds and epoxy compounds, and functions as a basic surface active agent.
- In the practice of this invention, the aforesaid basic compound may be used alone but is preferably used in combination with an acidic surface active agent such as phosphoric acid ester compounds, sulfonic acid compounds, sulfonic acid ester compounds and so on, in the form of a neutral salt at pH 3 to 10.
- The phosphoric acid ester compounds mentioned above include, among others, the compounds obtainable by reacting 2 to 5 moles of the adduct of 1 to 30 moles of ethylene oxide to an alkylphenol such as butylphenol, nonylphenol, dodecylphenol, etc., or a higher alcohol such as octyl alcohol, lauryl alcohol, oleyl alcohol, etc. with 1 mole of phosphoric anhydride generally at a temperature of 30 to 90°C or the compounds obtainable by reacting 2 to 5 moles of the block or random adduct of 1 to 10 moles of propylene oxide and 1 to 30 moles of ethylene oxide to said alkylphenol or higher alcohol with 1 mole of phosphoric anhydride generally at a temperature of 30 to 90°C.
- As examples of said sulfonic acid compounds or sulfonic acid ester compounds, there may be mentioned the compounds obtainable by reacting 1 to 2 moles of an alkylbenzene containing 6 to 24 carbon atoms, an α-olefin containing 8 to 26 carbon atoms, an alkylphenol containing 6 to 24 carbon atoms, a higher alcohol containing 6 to 22 carbon atoms, or an alkylphenol or higher alcohol-alkylene oxide adduct with 1 mole of a sulfonating agent such as sulfuric acid, fuming sulfuric acid, sulfuric anhydride, chlorosulfonic acid, sulfamic acid, etc. at a temperature from 10 to 120°C. As examples of said alkylphenol or higher alcohol-alkylene oxide adduct, there may be mentioned the block or random adduct obtainable by adding 1 to 30 moles of ethylene oxide or 1 to 10 moles of propylene oxide plus 1 to 30 moles of ethylene oxide.
- The basic compound and neutral salt thereof, which constitutes the above mentioned cold rolling oil additive, can be synthesized in any known manner. For example, they can be produced by the following method. To tetraethylenepentamine (which contains 5 nitrogen atoms) is added stearic acid and the mixture is subjected to condensation with elimination of water at an elevated temperature of 120 to 180°C to give an amide compound. To this is added polyoxyethylene nonylphenol ether phosphate or sulfonate at a temperature of 30 to 100°C to give a neutral salt with pH 7.
- Furthermore, the compound used according to the invention as a cold rolling oil additive preferably further contains a nonionic surface active agent with a HLB number of not less than 6. As examples of such nonionic surfactant, there may be mentioned the adducts of ethylene oxide, propylene oxide, butylene oxide or the like to C₈₋₂₂ alcohols, alkylphenols, fatty acids or polyhydric alcohol fatty acid esters. If the HLB number is less than 6, the stability of the emulsion is unsatisfactory and the incidence of oil stain increases. The above-mentioned C₈₋₂₂ alcohols include octyl alcohol, lauryl alcohol, stearyl alcohol, oleyl alcohol and so on. The alkylphenols include, among others, butylphenol, octylphenol, nonylphenol, dodecylphenol, etc. and the corresponding condensates with formaldehyde. The fatty acids include lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid and so on. The polyhydric alcohol fatty acid esters include, among others, the esters obtainable by reacting said fatty acids with glycerol, polyglycerol, pentaerythritol, sorbitol, ethylene glycol, propylene glycol or the like.
- The above mentioned cold rolling oil composition comprises the above-described compound to be used according to the invention as a additive and a lubricating oil component. As this lubricating oil component, any of the components heretofore in use as this type of rolling oil can be employed. As examples of such components, there may be mentioned animal oils, vegetable oils, mineral oils, and synthetic fatty acid esters. These oil components can be used singly or in combination. To be specific, there may be used any of mineral oils such as spindle oil, machine oil, turbine oil, cylinder oil etc.; animal and vegetable oils such as sperm oil, beef tallow, lard, rapeseed oil, castor oil, rice bran oil, soybean oil, palm oil, coconut oil, etc.; esters of fatty acids from beef tallow, coconut oil, castor oil, etc. with aliphatic monohydric alcohols containing 1 to 22 carbon atoms; and fatty acid esters synthesized from such fatty acids and polyhydric alcohols such as propylene glycol, pentaerythritol, sorbitol and so on.
- Generally, the rolling oil composition is based on an animal or vegetable oil, a mineral oil or a synthetic fatty acid ester and, if required, contains as a supplemental component one or more members of the group consisting of oil improving agents, high-pressure additives, rust inhibitors, antioxidants, emulsifiers, antifoams, etc. and is used as diluted with water into an emulsion of 0.1 to 10% concentration. Said cold rolling oil composition can also be used in the same manner. Thus, the compound to be used according to the invention as an additive is first dissolved in a base oil component and, then, diluted with water to form an emulsion. Alternatively, the compound to be used according to the invention as an additive may be first dissolved in water and then emulsified with the base oil component to form an emulsion. The level of addition of the compound to be used according to the invention as an additive based on the total weight of the cold rolling oil composition is 0.1 to 10 percent by weight and preferably 0.5 to 5 percent by weight.
- In addition to the above components, said cold rolling oil composition may further contain, as required, any of the known oil improving agents, high-pressure additives, rust inhibitors, antioxidants, defoamers and so on.
- Since, in the cold rolling oil composition, the protective colloid action of the additive of this invention allows the lubricating oil to be stably dispersed in water as fairly large particles, the oil component maintains a stable and fairly large particle size distribution even under agitated conditions with high shearing forces in the tank, circulating pump and so on.
- Moreover, since the large oil particles form a thick lubricating film on the metal work upon supply to the roll, the composition exhibits an excellent cold roll lubricating performance and insures a satisfactory circulation stability (the large particle size of oil is retained and no separation of the oil occurs even if the composition is recycled).
- Furthermore, when the neutral salt of a basic surfactant and an acidic surfactant is employed, its ability to become quickly adsorbed on the liquid and solid particles to render them hydrophilic helps eliminate the entrapping of infiltrating dirty oil or contaminents such as metal dust during the rolling operation and prevent fouling of the tank and mill line. These effects are not obtained with the conventional rolling oil compositions prepared using the ordinary emulsifiers. As a consequence, the composition obtained by using the compound to be used according to the invention as a cold rolling oil additive has a laudable feature that it helps insure a clean environment which has never been achieved with the conventional cold rolling oil emulsions. Furthermore, since the rolling oil composition obtained by using the compound to be used according to the invention as a cold rolling oil additive retains a stable cold-roll lubricating property, it is by far superior to the commercial rolling oil compositions heretofore available in lubricating performance and clean mill characteristic.
- Providing, thus, the use of a compound as a cold rolling oil additive which may be used in a cold rolling oil composition having excellent cold-roll lubricating and stable recycling characteristics, this invention contributes a great deal to the progress of rolling technology.
- The following examples and comparative examples are merely illustrative of this invention and should by no means be construed as limiting the scope of the invention.
- The use according to the invention of a compound as additives A through T, which are to be incorporated in rolling oil compositions are shown in Tables 1 and 2. The rolling oil compositions thus obtained, which were prepared by using these additives in predetermined proportions (by weight), are shown in Tables 3 and 4.
- The performance of these rolling oil compositions was evaluated by the following tests. The results are set forth in Tables 5 and 6.
- Using a Timken tester, the test was performed in accordance with JIS K 2519. Thus, in a tank, each rolling oil composition was diluted with water to a concentration of 5% and stirred by means of a homomixer at 8000 rpm to provide a dispersion at a temperature of 60°C and this dispersion was fed for circulation. The evaluation was made on the basis of the specific area within the seizure limit curves. The poorest rating was 1.0 (ratio). The larger this ratio, the more desirable is the lubricating property.
- To a 5% aqueous dispersion of each rolling oil composition was added 0.1% of iron power (particle size: not more than 1 µm) to provide a rolling oil dispersion at 60°C. Using a gear pump, this rolling oil dispersion was sprayed from a nozzle against the surface of a test steel plate (0.5 ℓ/min., 1 atm., 5 seconds) and dried. Two steel plates similarly treated were laid one on the other, pressed together at a pressure of 40 kg/cm² and heated at 130°C for 15 hours. Then, the assembly was annealed in an atmosphere of N₂ + 5%H₂ gas in an annealing furnace at 700°C for 2 hours and the degree of fouling of the surface of the steel plates was visually evaluated and rated according to the following criteria.

- To a 5% aqueous dispersion of each rolling oil composition was added 0.1% of iron powder (particle size: not more than 1 µm) to provide a rolling oil dispersion at 60°C. Using a gear pump, this dispersion was continuously sprayed at a pressure of 2.5 kg/cm² against an iron roll heated to 150°C in a closed liquid circuit. After 48 hours, the oil fraction of the dispersion, to the exclusion of the surface floating oil phase, was quantitated and the percent decrease from the initial concentration was determined by means of the following equation.
- To the rolling oil dispersion prepared in the above test (1) was added 3 g of aluminum sulfate and the mixture was stirred for 2 minutes. After adjustment to pH 7.0 with Ca(OH)₂, the mixture was further stirred for 10 minutes and, then, allowed to stand for 30 minutes. The surface oil phase was discarded and the clear liquid was recovered and tested for COD (chemical oxygen demand, KMnO₄ method).
