Problems solved by technology
Since the phosphating process can only be used for a short period of time, and it can only be temporarily rusted in a dry climate, such an anti-corrosion method is not only limited by conditions, but also the anti-corrosion effect cannot be effective for a long time; using electrophoresis technology for anti-corrosion treatment, Due to the reason of electric field shielding, the fuel tank and pipeline cannot be coated with electrophoretic paint, so the electrophoretic process technology has limitations
Therefore, the inner wall of the oil tank and pipeline of the prior art cannot remove rust and oil stains, so that the inner wall is rusted in a short period of time, causing metal impurities to fall off, causing the entire hydraulic system to reduce cleanliness and block the hydraulic valve body, resulting in control failure

The invention discloses an anti-corrosion coating for an inner wall of a hydraulic system. The anti-corrosion coating for the inner wall of the hydraulic system comprises the following components in weight percentage: 5-7% of silver powder, 4-8% of butyl acetate, 70-80% of modified acrylic resin, 0.3% of dust-proof agent, 3-8% of aromatic hydrocarbon solvent, 5-7% of color paste, 0.1% of leveling agent and 1.6% of anti-rust filler. The anti-corrosion coating for the inner wall of the hydraulic system is a product searched and developed mainly for meeting technical requirements of a hydraulic pumping system on long-term heat resistance, lasting pressure resistance and lasting rust resistance; and the anti-corrosion coating for the inner wall of the hydraulic system is long in oil-resistant time, resistant to high oil temperature and strong in anti-aging performance.
Description
technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating for the inner wall of a hydraulic system. Background technique [0002] At present, the oil tanks and pipelines of the working systems of domestic construction machinery, automobiles, and hydraulic workstations have been treated with decades-old rust removal, oil removal, and phosphating processes for anti-corrosion treatment. In recent years, there are also a small number of electrophoresis technology processing for anti-corrosion. Since the phosphating process can only be used for a short period of time, and it can only be temporarily rusted in a dry climate, such an anti-corrosion method is not only limited by conditions, but also the anti-corrosion effect cannot be effective for a long time; using electrophoresis technology for anti-corrosion treatment, Due to the shielding of the electric field, the fuel tank and pipeline cannot be coated with electroph...
