Abstract

The invention discloses an extreme pressure anti-wear additive. The extreme pressure anti-wear additive is prepared from the following raw materials in parts by weight: 10-20 parts of sublimed salicylic acid, 80-100 parts of boric acid, 3-4 parts of lithium hydroxide, 4-6 parts of calcium hydroxide, 40-60 parts of potassium hydroxide, 70-90 parts of water, 120-160 parts of base oil A, and 60-80 parts of base oil B. The sublimed salicylic acid and the lithium hydroxide are adopted, the calcium hydroxide is added, it is ensured that borate can be well dispersed through a special production technology, in the application process, the adverse effects on lubricant performance are minimized, the water-resisting property and the extreme pressure anti-wear property of a product are greatly improved, and the problem that the borate is prone to sedimentation is also solved effectively. The prepared extreme pressure anti-wear additive has the extremely-high extreme pressure anti-wear property andheat stability, four-ball test PB is greater than or equal to 2000 N, PD is greater than or equal to 8000 N, and the good anti-wear extreme pressure property is still be achieved when the using temperature reaches to 250 DEG C or above.

Description

technical field [0001] The invention relates to the field of petrochemical additives, in particular to an extreme pressure anti-wear additive and a preparation method thereof. Background technique [0002] About one-third of the metal materials in the world are consumed by oxidation corrosion and mechanical wear every year, and the loss in this area in my country is as high as 180 billion yuan per year. It can be seen how important it is to prevent metal corrosion and improve lubrication and anti-wear properties. For more than half a century, people have made unremitting efforts in the development of extreme pressure anti-wear and anti-friction oil agents to improve lubrication performance, and developed a variety of single agents and compound agents. Such as sulfur phosphorus (SP) gear oil extreme pressure anti-wear agent, internal combustion engine oil, anti-wear hydraulic oil zinc dialkyl dithiophosphate (ZDDP) anti-oxidation anti-corrosion anti-wear multi-effect agent, o...
