Abstract

The invention relates to a protective agent for a hydraulic steering system and a preparation method thereof, which is characterized in that it comprises the following components in parts by weight: 15-25 parts of isomeric pentaerythritol ester; Calcium sulfonate T106 2-6 parts; bis-octyl zinc dithiophosphate T203 2-8 parts; polyalphaolefin T803B 0.1-0.6 parts; viscosity index improver LZ7075 2-10 parts; antifoaming agent T902 0.001-0.010 parts . The protective agent of the present invention can maintain the original viscosity of the oil, reduce the thinning of the oil, and enhance the shear performance; help to reduce the generation of sludge and paint film; improve the working conditions of the seals and rings and prevent them from leaking; The formulation of grinding and extreme pressure components protects moving parts and metal parts from abrasion; enhances anti-foaming performance; is easy to degrade, and is absolutely safe and environmentally friendly no matter in the process of production, transportation, storage or use.

Description

technical field [0001] The invention relates to the technical field of automobile hydraulic steering system maintenance, in particular to a hydraulic steering system protective agent and a preparation method thereof. Background technique [0002] The steering system of a car is a mechanism used to change and restore the driving direction of the car and keep the car running straight, which has a great influence on the normal operation of the steering wheel and the safe driving of the car. In use, the working conditions of the automobile steering system are harsh, such as frequent changes in speed and load, long-term bending, torque shearing, and impact loads caused by uneven roads. , distortion, or loss of rust, cracks, and fractures, which will affect the handling, economy, and safety of the car. Once there is a problem with the steering system of the car, it is easy to cause an accident. Therefore, the normal operation of the automobile steering system plays a very import...
