Description
Technical field
The invention belongs to multifunctional macromolecule technical field of material, and in particular to a kind of low antistatic antirust of vapour lock is thin
The preparation method of film.
Background technology
Metal and metal product are in transport, storage process, it is easy to are subject to atmospheric corrosion and influence appearance, performance, very
To causing to scrap, it is therefore necessary to transport, period of storage is longer or the metal that is under high humidity, hot conditions and its product into
Row rust prevention packaging.Rust-preventing film is a new generation's innovation high-tech being combined based on high molecular material with the development of VCI vapor phase inhibitor technologies
Skill product.Distillation will be started by the VCI after anti-rust metal article rust-preventing film package encapsulation, contained in membrane body and volatilize antirust gas
The body factor, scattering and permeating extremely by antirust article surface and adsorb thereon, and the fine and close protection film layer of formation unimolecule thickness, isolation induces
The various factors of corrosion and the contact by antirust article surface, so as to effectively prevent the generation of corrosion.
Volatile rust prevention is a kind of new antirust, and VCI can slowly gasify at normal temperatures, space of its gas full of sealing,
VCI can be adsorbed on metal surface and form protective film, prevent superficial layer corrosion from departing from, so as to achieve the purpose that antirust.VCI gas
Phase rust-preventing film is notable using simple, time saving, saving of labor, clean, dry, antistatic, corrosion-free, rust-proof life limit for length, rust-proof effect, right
Environment and human body nonhazardous.Be widely used in electronic product, component of machine, vapour rub component, electronic apparatus, hardware etc. neck
