Embodiment 1

[0035] (1) Sulphurphosphating reaction: In a four-necked reaction flask equipped with a stirrer, a thermometer, an air duct and a gas absorption device, first add 176g (2mol) of sec-amyl alcohol and 260g (2mol) of 2-ethylhexanol , stir and pass N 2 Under protective conditions, 222 g (1 mol) of phosphorus pentasulfide was added dropwise in batches, the rate of addition was controlled to avoid too fast a temperature rise, the temperature was controlled at 90±2°C, and the reaction was performed at a constant temperature for 3-5 hours. The H2S gas that reaction produces introduces the absorption bottle that 178g30% concentration NaOH solution (1.33mol) is housed, and is converted into Na after the completion of the reaction. 2 212g of S and NaHS mixed solution was used for later use. The reactant in the four-neck flask is filtered after cooling, and obtains the micro-black transparent liquid of second amyl isooctyl dithiophosphoric acid, weighs 612g, yield 98.1%, acid value 146mg...

Abstract

The invention relates to the anti-abrasion agent field, in particular to an organic boron complex energy saving anti-abrasion agent and a preparation process thereof. The compositions by weight percentage of the organic boron complex energy saving anti-abrasion agent are as follows: organic boron: 40 to 80 percent; petroleum sulfonate of barium: 5 to 15 percent; isobutylene boride: 10 to 30 percent; sulfurized isobutylene: 5 to 15 percent. The organic boron complex energy saving anti-abrasion agent has scientific formula, reasonable design and good anti-abrasion, water-resistant and anti-rustperformance, can form a boronization laminated film with elasticity and strong adhesive force by being absorbed on the friction surfaces to play a role of apparent abrasion reduction and abrasion resistance, can be widely used in the lubricating systems of various machines, equipment and vehicles, and has good maintenance effect and certain energy saving effect.

Description

technical field [0001] The invention relates to the field of antiwear agents, in particular to an organic boron composite energy-saving antiwear agent and a preparation method thereof. Background technique [0002] The anti-wear agent can greatly reduce the frictional resistance of the protected machinery, save power energy, and prolong the life of the machinery exponentially. With the development of sulfur-phosphorus gear oils and hydraulic oils, boron-containing additives have begun to be used in such oils. Borates are a new type of environment-friendly extreme pressure anti-wear agent. Studies have shown that its extreme pressure performance, anti-wear performance, thermal oxidation stability, high temperature corrosion resistance and airtight performance are superior to some other types of extreme pressure agents. For example, the heat resistance temperature of general sulfur and phosphorus agents is about 130 ° C , while the heat-resistant temperature of borate is 150°...
