Abstract

A super-hydrophobic oil-proof self-cleaning aerosol comprises, by weight, one or more of a fluorine-containing compound and a silicone-containing compound 0.1-15%, lanthanide series compound 0.1-5%, nano material 0.1-10%, dissolve promoter 5-40%, diluents 10-60% and propellants 15-40%. A preparation method of the super-hydrophobic oil-proof self-cleaning aerosol comprises the following steps of weighing raw materials according to a formula, stirring and evenly mixing all raw materials except the propellants, respectively filling the raw materials into an aerosol can or a tinplate can or an aluminum can, plugging a valve into a filled can, sealing an opening, filling the propellants, and conducting online weighing, water bath leakage detection and label adhesion on the canned aerosol. The super-hydrophobic oil-proof self-cleaning aerosol has the following advantages that a production process is simple, large-scale production is facilitated, product perniciousness is low, the aerosol is very convenient to carry and use and is especially suitable for application of a spray gun in a large-scale constriction site; the aerosol has no temperature requirement in use and has no special condition requirements, is colorless, tasteless, high in adhesion force, long in service life and wide in application range and is resistant to friction.

Description

technical field [0001] The invention relates to super-hydrophobic coating technology, in particular to a super-hydrophobic and oil-proof self-cleaning aerosol and a preparation method thereof. Background technique [0002] The free energy of the material surface determines whether the material is hydrophilic or hydrophobic. The lower the free energy, the stronger the hydrophobicity; the microscopic roughness of the surface determines the strength of hydrophilicity and hydrophobicity. The rougher the surface, the stronger the hydrophobicity. Water is a substance with relatively high surface energy, so substances with lower surface energy than water, such as some substances containing silicon and fluorine, will show hydrophobicity, and water will shrink into a spherical shape on the surface of such substances. Since super-hydrophobic materials have many unique surface properties, such as waterproof, oil-proof, anti-fouling, snow-proof, anti-corrosion and self-cleaning and supe...
