Abstract

The invention relates to the technical field of metal corrosion resistance and in particular relates to a durable volatile antirust nonwoven fabric and a preparation method thereof. The preparation method comprises the steps: encapsulating a volatile corrosion inhibitor, further, carrying out spinning, and carrying out fixation on cellulose fibers; and then, forming a mesh, and sealing the mesh bycoating zeolite powder and a resin emulsion to form the volatile antirust nonwoven fabric. The durable volatile antirust nonwoven fabric is not only good in slow release feature, but also excellent in packaging performance, good in durability, beneficial to long-term slow release and capable of sustainably and slowly volatilizing the corrosion inhibitor at normal temperature and adsorbing the corrosion inhibitor to an exposed metal surface to effectively prevent an environmental atmosphere such as oxygen and moisture from corroding metal so as to achieve a good antirust effect.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a durable vapor phase antirust nonwoven fabric and a preparation method thereof. Background technique [0002] Metal is a kind of material with luster (that is, strong reflection of visible light), high ductility, easy conduction of electricity and heat conduction. The above properties of metals are all related to the free electrons contained in the metal crystals. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Metal minerals are mostly oxides and sulfides. Other forms are chlorides, sulfates, carbonates and silicates. The connection between metals is a metal bond, so the connection can be re-established by changing the position at will, which is also the reason why metals have good ductility. Metal elements usually only show positive valence in compounds. Relatively large atomic ma...
