Efficient wear-resistant micro-powder graphite lubricating grease for vehicle steel plate spring and preparation method of wear-resistant micro-powder graphite lubricating grease

Abstract

The invention discloses efficient wear-resistant micro-powder graphite lubricating grease for a vehicle steel plate spring and a preparation method of the wear-resistant micro-powder graphite lubricating grease. The efficient wear-resistant micro-powder graphite lubricating grease is formed by refining lithium-based grease, base oil and an oiliness agent, super-micro and fine graphite powder, an antioxidant and corrosion inhibitor; the efficient wear-resistant micro-powder graphite lubricating grease is efficient in extreme pressure wear-resistant performance and adhesiveness, low in friction coefficient, strong in bearing capability, and excellent in mechanical stability and chemical stability; and the lubricating grease is vapor-resistant, capable of resisting the corrosion of weak acid-base, and excellent in water resistance and water washing. The aims of providing lubricating, wear-resisting, rust-preventing and corrosion-resisting performances for the large lorry steel plate spring are realized in sever rugged environment.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a high-efficiency anti-wear micro-powder graphite lubricating grease for automobile leaf springs and a preparation method thereof. Background technique [0002] Automobile leaf springs need to be frequently filled with grease to increase the anti-wear lubrication performance. If the grease between the spring steel plates of the vehicle is lacking or fails, the contact surface of the spring steel plates will be severely corroded, which will not only reduce the shock absorption performance of the leaf springs , It will also cause abnormal friction and heat generation between the spring steel sheets, thereby reducing its elasticity and fatigue strength, reducing the shock absorption performance of the leaf spring, and once there are other overloaded external forces, it will break prematurely and shorten the leaf spring. The service life directly affects the ride comfort a...

[0002] Automobile leaf springs need to be frequently filled with grease to increase the anti-wear lubrication performance. If the grease between the spring steel plates of the vehicle is lacking or fails, the contact surface of the spring steel plates will be severely corroded, which will not only reduce the shock absorption performance of the leaf springs , It will also cause abnormal friction and heat generation between the spring steel sheets, thereby reducing its elasticity and fatigue strength, reducing the shock absorption performance of the leaf spring, and once there are other overloaded external forces, it will break prematurely and shorten the leaf spring. The service life directly affects the ride comfort and safety of the car; calcium-based grease, also known as butter grease, is still widely used as grease between automobile leaf springs in the current automobile maintenance industry. However, this grease is The technology in the 1930s has the defects of poor heat resistance, poor pressure resistance, and easy volatilization at high temperatures. It is already a product that has been eliminated in developed countries.
