Abstract

The invention provides a preparation method of an anti-corrosion coating. Through fluorinated polysiloxane in the primer, the anti-corrosion coating has good adhesion to a base and has good hydrophobicity. An inorganic filler can enhance the corrosion resistance of the anti-corrosion coating and provide a micron-scale surface. Nanometer hydrophobic particles in a fabric can enhance the hydrophobicity of the anti-corrosion coating. The nanometer particles interpenetrate with the micron-scale surface in the primer so that an uneven microscopic hydrophobic structure is formed and the hydrophobicity is further improved. The silane coupling agent can enhance the identity of the nanometer hydrophobic particles and the system so that dispersion is more uniform. The invention also provides a multifunctional anti-corrosion display frame. The interiors of mounting holes and through holes of the display frame are spray-coated with anti-corrosion coatings for preventing rust corrosion caused by long-term retention of water and prolonging the service life of the display frame.

Description

technical field [0001] The invention relates to a preparation method and application of an anti-corrosion paint, in particular to a preparation method of an anti-corrosion paint, a coating construction method and its application and a display stand. Background technique [0002] Anti-corrosion coating refers to a type of low surface energy coating that makes the contact angle between static water and the surface greater than 90 degrees or even 150 degrees after being applied to a smooth surface. The surface treated with anti-corrosion coating can achieve the effects of waterproof, anti-fog, anti-snow, anti-pollution, anti-adhesion, anti-oxidation, anti-corrosion and self-cleaning. [0003] Due to the defects of the formula and preparation method of the existing anti-corrosion coatings, when applied to the surface of the metal substrate, the adhesion with the substrate is not strong, resulting in poor durability of the anti-corrosion coatings. Under the condition of mechanic...
