Description
Technical Field
The utility model belongs to the technical field of U-shaped bolts, and particularly relates to a U-shaped bolt for an automobile.
Background
The U-shaped bolt, namely the saddle bolt, is named because of the U-shape, and the two ends of the U-shaped bolt are provided with threads which can be combined with nuts, and the U-shaped bolt is mainly used for fixing a tubular object or a sheet-shaped object.
The U-shaped bolt has wide application, and is mainly applied to building installation, mechanical accessory connection, vehicles, ships, bridge tunnel railways and the like, especially automobiles, and is used for stabilizing automobile chassis and frames. Such as leaf springs, are attached by U-bolts.
The U-shaped bolt is made of carbon steel and stainless steel, and is easy to corrode. In the prior art, the corrosion prevention technology of the U-shaped bolt mainly comprises an electroplating process and oxidation. The electroplating process is to plate zinc on the outer surface of the U-shaped bolt, but the defect surface of the galvanized layer is easy to be permeated by corrosive media such as acid, alkali, salt and the like, so that corrosion is caused. The oxidation is to immerse the U-bolts in molten salts of sodium nitrate and potassium nitrate, remove and heat treat in water to obtain a black oxide film, i.e., iron oxide (a compound of ferrous oxide and ferric oxide) on the surface thereof. However, the black oxide film is very thin, typically 0.5 to 1.6 μm, and has limited oxidation resistance.
Disclosure of utility model
The utility model provides a U-shaped bolt for an automobile, which aims to solve the technical problem that the U-shaped bolt is easy to corrode in the prior art.
The technical scheme adopted by the utility model for solving the technical problems is as follows.
A U-shaped bolt for an automobile comprises a U-shaped bolt;
the epoxy resin anti-corrosion coating is fixed on the outer surface of the U-shaped bolt;
And a hydrophobic oleophobic coating affixed to the outer surface of the corrosion resistant coating.
Preferably, the thickness of the epoxy resin anti-corrosion coating is 0.5-1 μm.
Preferably, the epoxy resin anticorrosive coating is made of epoxy fluorocarbon anticorrosive paint.
Preferably, the hydrophobic and oleophobic coating has a thickness of 0.5-1 μm.
Preferably, the material of the hydrophobic and oleophobic coating is super-hydrophobic and super-oleophobic nano-paint.
Compared with the prior art, the utility model has the beneficial effects that:
According to the U-shaped bolt for the automobile, the outer surface of the U-shaped bolt is provided with the epoxy resin anti-corrosion coating and the hydrophobic and oleophobic coating; the hydrophobic angle of the hydrophobic and oleophobic coating can reach 150 ℃, and after the solution of corrosive mediums such as wear resistance, acid and alkali resistance, salt mist resistance, corrosion resistance, acid, alkali, salt and the like contacts the outer surface of the U-shaped bolt, the solution is not easy to remain and permeate, and the steel is isolated from the corrosion environment so as to prevent the corrosion process; the inside of the hydrophobic and oleophobic coating is provided with the epoxy resin anti-corrosion coating, so that the adhesion between the hydrophobic and oleophobic coating and the surface of the U-shaped bolt steel can be increased, bidirectional protection can be realized, namely, the defect of the outer surface of the U-shaped bolt is prevented from affecting the hydrophobic and oleophobic coating (the defect of the hydrophobic and oleophobic coating cannot be corroded or the coating is incomplete), and the anti-corrosion effect can be still realized after the hydrophobic and oleophobic coating is used for a long time and has defects.
