Embodiment 1～6

[0031] According to the parts by weight in Table 1, weigh the required amount of metal deactivator, antioxidant, oily agent, rust inhibitor, detergent dispersant and antifoaming agent into the base oil (68 viscosity grade). Heat and stir at 70°C until it is completely uniform, then lower the temperature to 60°C, add an extreme pressure anti-wear agent, and stir until it is completely uniform to obtain the cold heading oil composition for cold heading and lubrication. The types and amounts of each component in the composition are shown in Table 1.

[0032] Among them, Rc2540 is sulfurized olefin; T321 is sulfurized isobutylene; T307 is phosphorothioate double ester amine salt; T404 is sulfurized cottonseed oil; T501 is 2,6-di-tert-butyl-p-cresol; Irganox L135 is mixed shielding component; Irganox L57 is alkylated diphenylamine; T552 is benzenetriazole, aldehyde and amine condensate; T561 is 2,5-dimercapto-1,3,4-thiadiazole derivative; T747A is alkenyl succinic acid half ester ; T...

[0034] The extreme pressure and anti-wear properties (comprehensive wear index, maximum seizure-free coincidence, sintering load, wear scar diameter), corrosion resistance (corrosion of copper flakes), and oxidation stability of the composition in [Examples 1 to 6] Rotating oxygen bomb value) and rust resistance (liquid phase corrosion B method) were tested. The test results are shown in Table 2.

Embodiment 6

[0035] Extreme pressure and wear resistance is one of the most important properties of cold heading oil. The various compositions in [Examples 1 to 6] were tested for indicators such as comprehensive wear index, maximum seizure-free coincidence, sintering load, and wear scar diameter. The larger the comprehensive wear index, maximum seizure-free coincidence, sintering load, wear scar diameter, etc., the better the extreme pressure and wear resistance performance of cold heading oil; the smaller the wear scar diameter, the lower the extreme pressure and wear resistance performance of the oil. The better. [Examples 1 to 6] In the extreme pressure and anti-wear properties of each composition, the comprehensive wear index is greater than 631N, the sintering load is not less than 6080N, the wear scar diameter is not greater than 0.35mm, and in [Examples 4 to 6] The maximum non-jamming load value of each composition is not less than 1100N, indicating that each composition can simult...

Abstract

The invention relates to a cold heading oil composition and an application thereof. The composition mainly solves the problems in the prior art that the extreme pressure anti-wear property and copper corrosion resistance of cold heading oil cannot satisfy usage requirements of partial cold heading equipment for lubrication unified oil supply for cold heading process and equipment, galling is generated on the surface of workpiece, or transmission gear shaft is corroded. The composition comprises the following components in parts by weight: a) 100 parts of mineral base oil; b) 0.1-5.0 parts of an anti-wear reagent at extreme pressure; c) 0.01-0.5 parts of a metal passivator; d) 1.0-15.0 parts of an oiliness agent; e) 0.005-0.5 parts of an anti-foaming agent. The anti-wear reagent at extreme pressure is a mixture of sulfurized olefin and at least one of sulfurized isobutylene, phenyl sulfide, sulfurized fatty acid ester or ammonium thiophsphonate. The metal passivator is selected from at least one of triazole derivatives or thiadiazole derivatives; the oiliness agent is a mixture of sulfurized plant oil and at least one selected from fatty acid ester or high-grade fatty alcohol. The technical scheme can better solve the problem, and is used for partial cold heading equipment for lubrication unified oil supply for cold heading process and equipment.

Description

Technical field [0001] The invention relates to a cold heading oil composition and its use. Background technique [0002] The cold heading process is one of the important processes in the metal processing technology. It is an indispensable manufacturing method for mass-produced automotive fasteners, motorcycles, bicycles, and automatic production of special shapes on household appliances. It has the characteristics of high forming contact stress and extremely high requirements for the extreme pressure performance of the cold heading forming oil. Therefore, active sulfur additives with excellent extreme pressure properties are often used in a large amount in cold heading oil products, but at the same time, they are more corrosive to brass. [0003] Gear is an important component in transmission. Gear oil is an important lubricating material to ensure the working efficiency of gear transmission and prolong the service life of gears. In the gear mechanism, it mainly prevents tooth s...
