Abstract

The invention relates to a hydraulic steering system protective agent and a preparation method thereof. The protective agent is characterized by comprising the following components in parts by weight: 15-25 parts of heterogeneous pentaerythritol ester, 50-80 parts of base oil 100N, 2-6 parts of high alkaline synthetic calcium sulfonate T106, 2-8 parts of zinc dioctyl dithiophosphate T203, 0.1-0.6 part of poly(alpha-olefin) T803B, 2-10 parts of viscosity index improver LZ7075 and 0.001-0.010 part of anti-foaming agent T902. The protective agent can achieve the effects of maintaining the original viscosity of oils, reducing thinning of oils and enhancing the shear property, is conducive to reducing oil sludge and paint films, has the effect of improving the working conditions of sealing elements and rings to prevent oils from leaking, has the effects of protecting moving parts and metal parts and preventing wear as the protective agent contains anti-wear and extreme pressure components, has the effect of enhancing the anti-foaming property, is easy to degrade and is absolutely safe and environmentally friendly in whether the production, transport, storage or use process.

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...
