Embodiment 1

[0022] Nano-type high-performance extreme pressure anti-wear lubrication care agent (I) includes: 18% paraffin base diluent oil (component A); 12% sulfur phosphorus bis-octyl basic zinc salt (component B); 68% organic phosphonic acid Salt and thiophosphate etc. mixture (component C); 1.2% vinyl acetate-fumarate copolymer (component D); 0.3% dodecenylsuccinic acid (component E); 0.5% nano Oil-soluble silicone compound (component F).

[0023] Conditioning agent (I) was added in 15W / CD40 base oil with 6%, carried out internal combustion engine bench performance test according to GB1105.2-87, and its evaluation result is shown in Table 1.

[0024] Table 1 Bench Performance Test Record Form

[0025]

[0026] The test conclusion is: under the no-load condition, the oil saving after adding the care agent (I) is 10.4%, which is mainly due to the reduction of the friction work by the nano lubricating oil. Fuel economy is around 1.7 percent when loaded. Soot emissions are s...

Embodiment 2

[0033] Nano-type high-performance extreme pressure anti-wear lubrication care agent (II) includes: 48% sulfoalkyl diluent oil (component A); 8% sulfur phosphorus bis-octyl basic zinc salt (component B); 7% dioxane 34% organic phosphonate and thiophosphate mixture (component C); 1.6% alkylnaphthalene (component D); 1.1% dodecenyl butadiene Diacid (component E); 0.3% nano oil soluble silicone compound (component F).

[0034] The care agent (II) was added to GL-5 85W / 90 base oil at 9%, and its extreme pressure and anti-wear properties were evaluated by a four-ball friction and wear tester. The evaluation results are shown in Table 3.

[0036] Pilot projects

[0037] As can be seen from Table 3: the lubricating oil with care agent (II) has a large PB value and a small long wear value d, indicating that the care agent has good extreme pressure performance and anti-wear performance, and is a class of lubrica...

Embodiment 3

[0039] Nano-type high-performance extreme pressure anti-wear lubrication care agent (III) includes: 40% sulfoalkyl diluent oil (component A); 12% sulfur phosphorus bis-octyl basic zinc salt (component B); 46% organic phosphine salt and thiophosphate mixture (component C); 1.0% vinyl acetate-fumarate copolymer (component D); 0.3% dodecenyl succinic acid (component E); 0.2% mercaptothiol Oxadiazole (component E); 0.5% nanoscale oil-soluble silicone compound (component F).

Abstract

The invention provides a nano type high-performance extreme pressure antiwear lubricating and nursing agent comprising: (1) a predetermined amount of thinning oil, (2) at least an oxidation and corrosion inhibitor, (3) at least a phosphor-containing extreme pressure antiwear agent, (4) at least a pour depressor, (5) at least a rust inhibitor, (6) and nano oil solution type siliconoxidation compound.

Description

technical field [0001] The invention relates to an extreme pressure anti-wear lubrication care agent, in particular to a nano-type high-performance extreme pressure anti-wear lubrication care agent. [0002] The present invention also relates to the application of the above-mentioned care agent. Background technique [0003] Mechanical wear losses and oil consumption due to friction are staggering. About 1 / 3 of the energy used in the industrial sector is consumed in various forms of friction; about 8% of the failure of mechanical parts is caused by various forms of wear. Adding lubricating oil additives can improve anti-wear, anti-friction and energy-saving performance, especially extreme pressure anti-wear additives become one of the keys to test the lubricating performance of lubricating oil. [0004] The unique ultrafine structure of nanomaterials makes it have the characteristics of high diffusivity, low melting point, high hardness, easy sintering, and high catalytic ...
