Abstract

The invention relates to an automobile automatic transmission fluid, and mainly aims at solving the problems of non ideal wear resistance and antioxidant properties of automobile automatic transmission fluids in the prior art. The composition comprises base oil accounting for 85.0 to 97.0% of the total weight; a viscosity index improver accounting for 0.2 to 10.0% of the total weight; an anti-wear reagent at extreme pressure, accounting for 0.2 to 2.0% of the total weight; an antioxidant accounting for 0.05 to 2.0% of the total weight; an antioxidant anticorrosion anti-wear agent accounting for 0.02 to 1.0% of the total weight; a dispersant accounting for 0.1 to 3.0% of the total weight; a detergent accounting for 0.05 to 2.0% of the total weight; an anti rust agent accounting for 0.05 to 3.0% of the total weight; a metal deactivator accounting for 0.02 to 3.0% of the total weight; a pour point depressant accounting for 0.2 to 8.0% of the total weight; and an antifoaming agent accounting for 0.0001 to 0.02% of the total weight. The automobile automatic transmission fluid has the advantages of good antioxidant anticorrosion anti-wear properties.

Description

(1) Technical field [0001] The invention relates to an automobile automatic transmission fluid, which is mainly used in an automobile automatic transmission system and belongs to the field of lubricating oil. (2) Background technology [0002] Automobile transmission fluid is mainly used in the automatic transmission system of automobiles, acting as an intermediate medium and lubricating. It is usually required to have good viscosity-temperature properties, corrosion resistance, wear resistance, thermal oxidation stability, and anti-foaming properties. In order to meet the above performance, general automatic transmission fluid needs to add various additives such as viscosity index improver, dispersant, antioxidant, extreme pressure and antiwear agent, rust inhibitor, metal deactivator, pour point depressant, antifoaming agent, etc. [0003] With the development of automatic transmissions, automatic transmission fluids are also constantly being upgraded. The specifications o...
