Description

A kind of zinc alloy vapor phase inhibitor and preparation method thereof

Technical field

The present invention relates to metal treatment field, be specifically related to a kind of zinc alloy vapor phase inhibitor and preparation method thereof.

Background technology

Metal processing piece gets rusty easily in the process of process for processing and transport, and once there is corrosion, not only affects outward appearance and function, even likely cause the wasting of resources.Rust-preventive agent to join in medium to reach the chemical agent of metal rust preventing object, can form layer protecting film on parts surface, suppresses the corrosion that moisture and other chemical composition cause.But some metal works has the antirust unapproachable positions of oiling such as bending aperture, and vapor phase inhibitor has special protection effect to this.The principle of vapor phase inhibitor is by constantly distillation automatically, evaporates into gas, just can carry out corrosion protection to metals such as iron and steel when this gas reaches capacity state.Vapor phase inhibitor has the advantages that the corrosion protection phase is permanent, can provide all-pervasive protection, and its use is protected and removes very convenient, and environmental pressure is little, and purposes is very extensive.
