Problems solved by technology

[0004] Motorcycle shock absorber oil requires moderate viscosity, good viscosity-temperature performance, and good low-temperature performance, so higher requirements are put forward for the selection of base oil, but at present, most motorcycle front shock absorber oils in my country are simple binary mixtures. Mineral oil, the viscosity-temperature characteristics and low-temperature performance are extremely unsatisfactory, even after adding additives, it is still difficult to meet the normal working environment of motorcycle shock absorbers (40°C~-40°C)

Abstract

The invention discloses an oil composition for a front shock absorber of a motorcycle and a production method thereof. The oil for the front shock absorber of the motorcycle comprises the following raw material components per kilogram: 900 to 950 grams of base oil, 10 to 40 grams of extrcme pressure antiwear additive, 10 to 30 grams of antioxidant, 10 to 30 grams of pour point depressant and 0.0005 to 0.001 gram of anti-foaming agent. The preparation method of the oil composition for the front shock absorber of the motorcycle comprises the following steps of: after mixing component oils in the base oil according to a certain ratio, adding the anti-foaming agent and the pour point depressant; after heating to a temperature of 75 to 85 DEG C and stirring for 4 hours, adding the extrcme pressure antiwear additive and the antioxidant; stirring the mixture for 4 hours at a temperature of 50 to 60 DEG C; and filtering to obtain the oil composition for the front shock absorber of the motorcycle, which is disclosed by the invention and has excellent low temperature fluidity, excellent shock absorption, shear stability, lubrication, inoxidizability and antirust property. Various index requirements of the oil composition for the front shock absorber of the motorcycle are met.

Description

Technical field [0001] The present invention involves a motorcycle's front shock absorber oil composition. It is a kind of oil for reducing the vibration of motorcycles in the exercise, ensuring the smoothness and comfort of driving, and improving the service life of motorcycles and the stability of manipulation stability.Class mixture. Background technique [0002] In order to ease and attenuate motorcycles due to the impact and vibration of the road unevenness during driving, to ensure the smoothness and comfort of driving, and to improve the life of the motorcycle's usage and the stability of the manipulation.Device. [0003] Due to the development of the manufacturing technology of modern motorcycles, the driving field of motorcycles is too large, and the number of roads in roads increases, which leads to higher requirements for shock absorbers and its oil products.The requirements of characteristics, low temperature liquidity, rubber compatibility, oxidation stability, and a...
