Description
Technical Field
The invention belongs to the technical field of lubricating oil, and particularly relates to low-carbon environment-friendly high-performance industrial gear oil and a preparation method and application thereof.
Background
Industrial gear oil is widely applied to closed gear devices in industries such as metallurgy, mine, metal processing and the like, and along with development of scientific technology and industrial production, gear transmission is developed towards the directions of small volume, light weight, high speed, heavy load and high power. Therefore, the oil product used by the gear is required to have wider viscosity-temperature performance, more excellent bearing capacity, higher transmission efficiency and longer service life, and also has high biodegradation rate and lubricating property, thereby being suitable for preparing environment-friendly industrial gear oil.
With the development of industrial gear equipment and the continuous improvement of the requirements of industrial gear oil specification diffraction on gear lubrication, the advantages of synthesizing industrial gear oil are increasingly revealed. However, the existing synthetic industrial gear has single oily performance, cannot realize better comprehensive performance, has poor stability, needs to be replaced frequently, has overlarge peculiar smell, and cannot bring better use experience. Therefore, there is a need to develop an industrial gear oil which is excellent in combination properties and can meet the requirements of energy saving, environmental protection, safety and the like.
Disclosure of Invention
The invention aims to provide low-carbon environment-friendly high-performance industrial gear oil, and a preparation method and application thereof. The low-carbon environment-friendly high-performance industrial gear oil has excellent comprehensive performance, has a certain repairing function on aging and abrasion of mechanical equipment, comprehensively improves the performances of oxidation resistance, lubricating performance, biodegradability, corrosion resistance, rust resistance, extreme pressure wear resistance, emulsification resistance and the like, and can solve the problem of overlarge taste of the traditional gear oil.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the low-carbon environment-friendly high-performance industrial gear oil comprises the following components in parts by weight: 70-120 parts of base oil, 0.1-1 part of antioxidant, 0.1-1 part of antiwear agent, 0.2-1 part of extreme pressure agent, 0.05-0.5 part of metal deactivator, 0.05-0.5 part of antirust agent, 0.005-0.1 part of anticoaming agent and 0.01-0.5 part of anti-foaming agent;
the base oil comprises 10-30 parts of degradable polyol ester and 60-90 parts of poly alpha olefin.
Preferably, the low-carbon environment-friendly high-performance industrial gear oil comprises the following components in parts by weight: 90-105 parts of base oil, 0.2-0.5 part of antioxidant, 0.2-0.5 part of antiwear agent, 0.4-0.8 part of extreme pressure agent, 0.1-0.2 part of metal deactivator, 0.1-0.2 part of antirust agent, 0.01-0.02 part of anticoaming agent and 0.02-0.1 part of anticoaming agent.
Preferably, the base oil comprises 20-25 parts of degradable polyol ester and 70-80 parts of polyalphaolefin.
Preferably, the kinematic viscosity at 40℃per 100 parts by weight of the degradable polyol ester is 18-22mm 2 and/S, wherein the viscosity index is more than or equal to 140.
More preferably, the kinematic viscosity at 40℃per 100 parts by weight of the degradable polyol ester is 18.5-20.5mm 2 /S。
Preferably, the polyalphaolefin is a combination of polyalphaolefin-1 having a viscosity index of 130 to 160 and polyalphaolefin-2 having a viscosity index of 180 to 200.
Preferably, the mass ratio of the poly alpha olefin-1 to the poly alpha olefin-2 is (75-85): (15-25). If the ratio of the poly alpha olefin-1 to the poly alpha olefin-2 is not proper, the oil film strength and the thickness of the gear oil are not enough, the gear oil is excessively worn, the oil film thickness is not enough, the oil film strength is poor, and an oil film with enough thickness is not easy to form on a friction surface with high temperature and high pressure, so that the machine parts cannot be lubricated normally.
More preferably, the mass ratio of polyalphaolefin-1 to polyalphaolefin-2 is 81:19.

Performance testing
The low-carbon, environment-friendly and high-performance industrial gear oils prepared in examples and comparative examples were subjected to performance tests, and test items and test standards are shown in table 1. The results of the performance test are shown in Table 2.
TABLE 1
TABLE 2
From the experimental data in table 2, it can be known that the industrial gear oil prepared by the embodiment of the invention has good comprehensive performance, can comprehensively improve the performances of oxidation resistance, lubricating performance, biodegradability, corrosion resistance, rust resistance, extreme pressure wear resistance, emulsification resistance and the like, and prolongs the oil change period. Compared with example 3, in example 6, the equivalent amount of acid phosphate amine salt is selected to replace boronated phosphorothioate ammonium salt, the appearance of the prepared gear oil cannot be in a transparent state, and meanwhile, the corrosion resistance, the foam performance, the anti-emulsifying performance and the extreme pressure wear resistance are reduced; in the embodiment 7, the equal amount of the sulfur isobutylene prepared by the normal pressure process is selected to replace the sulfur isobutylene prepared by the normal pressure and high pressure processes, and the prepared gear oil has the corrosion resistance, the foam property and the extreme pressure abrasion resistance which are reduced; in example 8, the equivalent amount of thiadiazole derivative is used for replacing benzotriazole derivative, and in example 10, equivalent amount of polyethylene oxide-propylene oxide ether is used for replacing tetrapolyoxypropylene derivative, so that the foaming property and the anti-emulsifying property of the gear oil are both reduced; in example 9, the gear oil prepared by replacing synthetic barium sulfonate with equal amount of barium dinonylnaphthalene sulfonate has precipitation, and has poor foam property and extreme pressure wear resistance.
Compared with example 3, the base oil component selected in comparative example 1 is different, and only a single degradable polyol ester is selected as the base oil component in comparative example 2, so that the final prepared industrial gear oil has poor comprehensive properties such as water repellency, corrosion resistance, anti-foaming property, extreme pressure lubricating property and the like. Wherein the relative viscosity of the gear oil of comparative example 1 cannot meet the standard requirements; the gear oil prepared in comparative example 2 has too low motion viscosity at 40 ℃ to meet the requirements of products, and meanwhile, due to the too small viscosity, the corresponding parameters of the abrasive spot diameter, the maximum seizure-free load and the sintering load cannot be measured. The antioxidant selected in comparative example 3 was unsuitable in composition, resulting in the produced industrial gear oil having significantly inferior appearance, stability (foam property, demulsification property) and liquid phase rust and the like.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
