The invention discloses a protective coating and a preparation method and application thereof. The preparation raw materials of the protective coating include: bihydrolyzable functional group silane and polyhydrolyzable functional group silane; A functional group silane, the polyhydrolyzable functional group silane is a silane containing two or more hydrolyzable functional groups linked to Si. Based on the reaction characteristics of silane molecules containing hydrolyzable groups, the present invention successfully applies the hydrophobic organosilicon system to the preparation of protective coatings. The protective coatings of the present invention are coated and cured to form coatings with excellent strength and toughness , adhesion, hydrophobicity and oleophobicity and anti-corrosion effect, suitable for surface protection of various substrates, especially inorganic substrates such as metals. |
