Liquid anti-rust wax for long-term protection of ferrous metal and preparation method thereof

Abstract

The invention relates to liquid anti-rust wax for long-term protection of ferrous metal. The liquid anti-rust wax comprises the following raw materials of refined paraffin wax, C5 petroleum resin, N0.80 ceresin wax, aluminum distearate, T743 barium soap, wool fat magnesium soap, 2,6-ditert-p-cresol, wool fat, vaseline and No.200 solvent soil; various components are blended according to the steps to obtain a finished product. When the liquid anti-rust wax disclosed by the invention is used, the anti-rust treatment is performed by adopting the modes of brush coating, dip coating and spray coating; after 24 hours, a film layer is uniform and is crack-free, and the thickness of the film layer is more than 25 micrometers; the salt fog resisting time of the film layer of No.45 steel can reach over 90 days; the film layer is good in adhesion, so the anti-rust effect cannot be influenced by general collision; the film layer is dry and cool, so the influence on normal package is avoided, and the flowing is avoided under the temperature condition of below 80DEG C; the liquid anti-rust wax is the anti-rust wax with good anti-rust effect and durability.

Description

technical field [0001] The invention belongs to the technical field of ferrous metal antirust, in particular to a liquid antirust wax suitable for long-term protection of ferrous metals and a preparation method thereof. Background technique [0002] Ferrous metal is the general term for iron, chromium and manganese in the industry, and also includes alloys of these three metals, especially alloy ferrous metal steel and steel, mainly because the surface of iron is covered with a layer of iron tetraoxide and brown after rusting. A mixture of ferric oxide, so it appears black. Ferrous metals must be anti-rust during transportation or storage. Generally, thin-film anti-rust oil, dura-film anti-rust oil or anti-rust grease are commonly used. These anti-rust measures have problems: 1. The film anti-rust oil is attached The force is poor, and it is easy to be scratched during transportation or storage, resulting in a decline in the anti-rust effect; 2. The hard film anti-rust oil ...

AI Technical Summary

Problems solved by technology

Ferrous metals must be anti-rust during transportation or storage. Generally, thin-film anti-rust oil, dura-film anti-rust oil or anti-rust grease are commonly used. These anti-rust measures have problems: 1. The film anti-rust oil is attached The force is poor, and it is easy to be scratched during transportation or storage, resulting in a decline in the anti-rust effect; 2. The hard film anti-rust oil has good adhesion, but the film layer is brittle and thin, and a slight external force will cause damage to the thin layer , leading to a decline in the anti-rust effect; 3. The adhesion of the anti-rust grease is average, it will not dry after application, it will stick to the outer packaging, and it will melt and flow away when the ambient temperature is high, resulting in a decline in the anti-rust effect
