Abstract
The invention discloses extreme pressure-resistant open gear oil and a preparation method thereof, wherein the extreme pressure-resistant open gear oil is prepared from the following components in parts by weight: 100 parts of degradable base oil, 3-5 parts of sulfurized fatty acid ester, 1-3 parts of synergist, 0.2-2 parts of antioxidant and 1.5-3 parts of dispersant; the preparation method of the synergist comprises the following steps: adding 1-amino-4-methylpiperazine, 5-bromothiazole and a catalyst into an anhydrous organic solvent, and reacting to obtain the synergist. The protective oil film is formed by matching the synergist with the sulfurized fatty acid ester, so that the corrosivity of the sulfurized fatty acid ester on the metal surface can be reduced, the synergist and the sulfurized fatty acid ester have synergistic effects on improving the extreme pressure resistance and the anti-fatigue effect of the extreme pressure open type gear oil, and the protective oil film formed by combining the synergist and the sulfurized fatty acid ester has stronger combination stability with the metal surface of the gear and higher oil film strength, so that the extreme pressure resistance and the anti-wear property of the extreme pressure open type gear oil are enhanced.
Description
Technical Field
The invention relates to the technical field of gear oil, in particular to extreme pressure-resistant open gear oil and a preparation method thereof.
Background
The extreme-pressure-resistant open gear oil mainly comprises two parts, namely base oil and an additive, wherein the base oil of the extreme-pressure-resistant open gear oil mainly comprises degradable base oil, mineral oil and synthetic oil, wherein the mineral oil and the synthetic oil are mostly prepared on the basis of petroleum, most of the mineral oil and the synthetic oil are difficult to degrade, have serious pollution and are easy to destroy the ecological environment balance after being left in the environment for a long time. The degradable base oil has the advantages of low pollution and good biodegradability, and the pollution treatment cost is obviously low, thereby meeting the requirements of the modern society on environmental protection and energy conservation.
The traditional extreme pressure antiwear agents are compounds containing sulfur, chlorine or phosphorus, but most of the compounds are suitable for mineral base oil, have adverse effects on the biodegradability of the biodegradable base oil, and are particularly harmful to active microorganisms or enzymes playing a role in the degradation process of the base oil. The sulfurized fatty acid ester has good biodegradability and is a commonly used extreme pressure antiwear agent in biodegradable gear oil, but the additive has a slow corrosion effect on metals.
Disclosure of Invention
In order to improve the corrosivity brought to the metal surface by adding a sulfurized fatty extreme pressure antiwear agent, the application provides an extreme pressure open gear oil.
The extreme-pressure-resistant open gear oil is prepared from the following components in parts by mass:
degradable base oil 100 parts
3-5 parts of sulfurized fatty acid ester
1-3 parts of synergistic agent
0.2 to 2 portions of antioxidant
1.5-3 parts of dispersant
The preparation method of the synergist comprises the following steps: adding 1-amino-4-methylpiperazine, 5-bromothiazole and a catalyst into an anhydrous organic solvent, and reacting to obtain the synergist.
The synergistic agent is matched with the sulfurized fatty acid ester to form a protective oil film, so that on one hand, the corrosion effect of the sulfurized fatty acid ester on the metal surface can be reduced, irregular micro pits and initial cracks are not prone to occurring on the metal surface due to corrosion, the synergistic agent is high in binding property with the metal surface, the protective oil film formed by binding with the sulfurized fatty acid ester has high binding stability and excellent oil film strength, and the synergistic effect on improving the extreme pressure resistance and fatigue resistance of the extreme pressure open type gear oil is remarkable.
The extreme pressure resistant open gear oil formed by matching the sulfurized fatty acid ester, the synergist, the antioxidant and the dispersant has the advantages of being small in additive amount, good in anti-wear and extreme pressure resistant effects, long in service life, non-toxic, resistant to pitting corrosion, high-temperature anti-oxidation, waterproof, biodegradable and capable of meeting the requirement of environmental protection, can be applied to automatic lubrication of open gears in severe working condition environments of heavy industry, and is used for improving damage to equipment in working environments such as high temperature, water vapor and heavy load.
Preferably, the reaction temperature of the 1-amino-4-methylpiperazine and the 5-bromothiazole is 80-100 ℃, and the reaction time is 6-10h.
When the reaction temperature is 80-100 ℃, the reaction time is 6-10h, and the activity of the 1-amino-4-methylpiperazine and the 5-bromothiazole is higher, the 1-amino-4-methylpiperazine and the 5-bromothiazole can be quickly combined to generate the synergist under the catalytic action of the catalyst, the occurrence of side reactions is reduced, and the reaction rate and the reaction yield of the synergist are improved.
Preferably, the molar ratio of the 1-amino-4-methylpiperazine to the 5-bromothiazole is 1-1.5:1.
the application comprises the following steps of controlling the molar ratio of 1-amino-4-methylpiperazine to 5-bromothiazole to be 1-1.5: the 1, 1-amino-4-methylpiperazine and the 5-bromothiazole are fully combined and collided in the reaction process, which is favorable for the smooth reaction.
Preferably, the catalyst is anhydrous potassium carbonate.
The anhydrous potassium carbonate is used as a catalyst for catalyzing the reaction of the 1-amino-4-methylpiperazine and the 5-bromothiazole, so that the reaction is oriented to the direction of synthesizing corrosion resistance, side reactions are reduced, reaction impurities which are not easy to remove are reduced, the interference of the impurities on the performances of all aspects of the extreme pressure open type gear oil is reduced, and the extreme pressure resistance and the fatigue resistance of the extreme pressure open type gear oil are further improved.
Preferably, the anhydrous organic solvent is anhydrous N, N-dimethylacetamide.
The 1-amino-4-methylpiperazine, the 5-bromothiazole and the catalyst are dissolved in the anhydrous N, N-dimethylacetamide to form a stable homogeneous phase, and the anhydrous N, N-dimethylacetamide is used as a reaction solvent, so that the reaction is promoted, and the reaction yield is improved.
Preferably, the volume ratio of the anhydrous organic solvent to the mol ratio of the 5-bromothiazole is 3-10ml.
By controlling the ratio of the anhydrous organic solvent to the amount of the 5-bromothiazole, the reaction is favorably controlled, so that the reaction yield is poor.
Preferably, the degradable base oil is prepared by compounding 60-80 parts by mass of liquid paraffin, 10-15 parts by mass of linoleic acid and 10-15 parts by mass of corn oil.
