Description

technical field [0001] The invention generally relates to the field of antirust films, and in particular, relates to vapor phase antirust paper with ultra-long antirust function and a preparation method thereof. Background technique [0002] Metal objects are easily corroded in the atmosphere. If no measures are taken, the corrosion will become more and more serious. Not only the appearance will be damaged, but also its performance will be greatly reduced with the intensity of the corrosion. Therefore, in order to prevent corrosion, sealing metal objects is an important anti-rust method. For a long time, vapor phase antirust paper has been widely used as an important antirust wrapping material. Generally, a vapor phase antirust agent is coated on the base paper. Such antirust paper uses kraft paper as the base paper, and coats a layer of vapor phase corrosion inhibitor on it, which will automatically volatilize to the metal surface through the vapor phase corrosion inhibito...
