Abstract

The present invention relates to a water base rust-resisting protection agent for metal sheet, band and foil product. Said rust-resisting protecting agent is formed from wax substance, rust-resisting agent, adsorbing agent and surfactant. Said protection agent is an emulsion liquor, can be applied or sprayed on the surface of metal sheet, band and foil product so as to form a layer of uniform, compact and bright protecting layer with the characteristics of resisting heat, resisting cold, resisting wet-heat and easy-washing, can be used for protecting the metal sheet, band and foil product.

Description

1. Technical field [0001] The invention relates to a metal antirust agent, in particular to an antirust protective agent used for metal plates, strips and foil products during storage and transportation. 2. Background technology [0002] The antirust protection of metal products is a widespread problem, and the research work in this field is also relatively active, and there are many published prior art. Introduced in CN1041621 is an ultra-thin anti-rust oil for ferrous metal products, which is an ultra-thin anti-rust oil composed of additives such as machine oil, kerosene, barium sulfonate and corrosion inhibitor. Because this kind of anti-rust oil forms an ultra-thin soft film anti-rust layer on the metal surface, the temperature resistance, humidity resistance, salt spray resistance, and corrosion resistance are not good, and the surface of metal products is easy to stick and absorb dust. , It should be cleaned when used, and it is easy to generate waste water.
