Coating protection method

A protection method of a coating comprises the steps that a base body is provided, and the base body comprises a body and a coating arranged on the surface of the body; rubbing the surface of the substrate provided with the coating so as to enable the substrate to carry positive charges; the surface of the base body provided with the coating is coated with protective liquid, the protective liquid contains an anionic surfactant, the positive charges and the anionic surfactant attract each other so that the protective liquid can be adsorbed to the surface of the base body, and the protective liquid covers the coating; and standing the substrate coated with the protective liquid, so that the protective liquid forms a protective layer to cover the surface of the coating so as to protect the coating. 一种涂层的保护方法，包括提供基体，基体包括本体以及设置于本体表面的涂层；摩擦设置有涂层的基体的表面，以使基体携带正电荷；在设置有涂层的基体的表面涂覆防护液，防护液中含有阴离子表面活性剂，正电荷与阴离子表面活性剂相互吸引，以使防护液吸附于基体的表面，防护液覆盖涂层；静置涂覆完防护液的基体，以使防护液形成保护层覆盖在涂层的表面以保护涂层。
