()(a) 一般式、
The present invention relates to a lubricating oil composition, and more particularly to a lubricating oil composition with significantly improved sludge formation prevention properties, which comprises a base oil containing a specific extreme pressure agent and a copolymer having a specific structure as essential components. products, particularly hydraulic oil and gear oil compositions. There are directional control valves, flow control valves, etc. in the hydraulic circuit.
Since there are various types of valves with very narrow gaps,
Contamination of foreign substances such as dirt and generated sludge into the hydraulic fluid used is extremely disliked. On the other hand, recent hydraulic units are becoming more pressurized and faster, and the thermal conditions for hydraulic fluid are becoming increasingly severe. Moreover, in recent years, the use of servo valves in hydraulic circuits, which are more sensitive to foreign matter contamination, has become commonplace, so improving the ability of hydraulic fluid to prevent sludge formation has become the most important and urgent issue. . Thermal conditions for gear oils are also becoming more severe due to higher speeds and higher pressures in machinery, similar to those for hydraulic oil, and improving thermal stability has become an important issue. Conventionally, detergent dispersion has often been added as an additive to prevent sludge formation in lubricating oils. However, the addition of conventional detergent-dispersing agents has the disadvantage that other properties of the lubricating oil are degraded. For example, when metal detergent dispersants such as petroleum-based sulfonates and phosphonates, which are common detergent dispersants, and ashless detergent dispersants such as succinic acid and amine detergents are used, the wear resistance and demulsification properties of lubricating oils are significantly improved. It will drop. Therefore, conventionally, when adding these detergents and dispersants to lubricating oils, the only options were to add them in small amounts to avoid interfering with other properties, or to add them in effective amounts at the expense of other properties. . The present invention provides a lubricating oil composition, particularly a hydraulic oil and gear oil composition, which has excellent properties necessary for a lubricating oil such as wear resistance and demulsification properties, and has significantly improved sludge formation prevention properties. With the goal. As a result of repeated research in order to improve the sludge formation prevention properties of lubricating oil without sacrificing other properties, the present inventors combined a specific extreme pressure agent and a copolymer with a specific structure into the base oil. The present inventors have discovered that a lubricating oil composition formed by the following methods satisfies this required performance, and have completed the present invention. That is, the present invention uses mineral oil and/or synthetic oil as a base oil, and comprises () a phosphinate, a phosphonate, a phosphoramidate, an amine phosphate, a reaction product of a hydrocarbon with phosphorus sulfide, an amine salt of a thiophosphate. one or more phosphorus-based extreme pressure agents and/or sulfur-based extreme pressure agents selected from the group, and ()(a) general formula,

The molar ratio of component and component (b) is arbitrary, but generally
The ratio is about 80:20 to 95:5. Although the method of the copolymer reaction is arbitrary, the copolymer can usually be easily obtained by radical solution polymerization of components (a) and (b) in the presence of a polymerization initiator such as benzoyl peroxide. The amount of component () added to the base oil is arbitrary, but usually 0.01 to 20% by weight of the base oil, preferably
It is desirable to blend 0.1 to 10% by weight. The lubricating oil composition of the present invention can be obtained by blending component (a) and component (b) into a base oil as essential components, but if necessary, other lubricating oil additives that are commonly used in practice, such as oxidation Inhibitors, pour point depressants, corrosion inhibitors, rust inhibitors, metal deactivators, antifoaming agents, etc. may be added. Also, if the amount is small, a metallic detergent dispersant or an ashless detergent acid separating agent can be added. The lubricating oil composition of the present invention is particularly preferably used as a hydraulic oil and gear oil, but it can also be used as a lubricating oil for various other uses. Next, the present invention will be explained in more detail with reference to Examples and Comparative Examples; however, the present invention is not limited to these Examples as long as the gist thereof remains unchanged. Example 1, Reference Examples 1 to 2, and Comparative Examples 1 to 4 Lubricating oil formulations Example 1 and Reference Examples 1 to 2 were obtained using the compositions listed in Table 1, and their evaluation was conducted using the vane pump test (wear resistance) shown below. A sludge formation test (to evaluate sludge formation prevention properties), and a demulsification test (to evaluate demulsification properties) were conducted. The results are shown in Table 1. Vane Pump Testing: ASTM D2882 Vane Pump Testing (VANE PUMP TESTING OF
PETROLEUM HYDRAULIC FLUIDS), total wear of vanes and rings (mg)

It was left in an air constant temperature bath at 160°C for 120 hours. The amount of sludge produced was determined by diluting the sample oil after the test with n-hexane, filtering it through a 5 μm telelon filter, and measuring the weight. Demulsification test: Conducted in accordance with JIS K 2520 lubricating oil demulsification test method. For comparison, we also show a case in which component () is not used (Comparative Example 1), a case in which an antioxidant is used in place of component () (Comparative Example 2), and a case in which a metal-based detergent and dispersant is used in place of component (). Similar tests were conducted for the case where the ashless detergent and dispersant was used (Comparative Example 3) and the case where an ashless detergent and dispersant was used instead of the component () (Comparative Example 4), and the results are also listed in Table 1. The substances in the composition of Vote 1 are as follows. (a) Base oil: Refined mineral oil with a kinematic viscosity of 32 cSt (@40℃), (b) Extreme pressure agent: Zinc diothyphosphate-based extreme pressure agent: Zinc bis(2-ethylhexyl) dithiophosphate, Phosphorus-based extreme pressure agent: Dioctyl Amine didodecyl phosphate Sulfur-based extreme pressure agent: sulfurized olefin, (c) copolymer; A: C1 - C18 alkyl methacrylate and N-

It can be seen that the sludge formation prevention property is significantly improved. On the other hand, when component () is not used (Comparative Example 1) and when an antioxidant is used in place of component () (Comparative Example 2), the results of the sludge formation test are significantly inferior. As is clear, when extreme pressure agents and ordinary refining dispersants are used together to improve sludge formation prevention properties (Comparative Examples 3 and 4), compared to when only extreme pressure agents are used (Comparative Example 1), It can be seen that although the results of the sludge formation test are improved, the results of the vane pump test and the demulsification test are worsened, causing a practical problem. Further, although Example 1 is almost equivalent to Reference Examples 1 and 2 in the sludge formation test, it is superior in the vane pump test and also provides good results in the demulsification test.
