Compound iron oxide red rust resisting pigment

Abstract

The invention discloses a compound iron oxide red rust resisting pigment, which contains the following components in percentage by weight: 20-80 percent of ferric oxide and 20-80 percent of iron phosphate. The invention has the following advantages that: firstly, the invention integrates the chemical rust resisting characteristics of iron oxide red physical shielding rust resistance and phosphates, has strong weather resistance and good rust resistance and is particularly suitable for metal rust resistance in relatively-severe environment; secondly, the invention can utilize industrial waste residue so as to save resources and reduce the production cost; and in addition, the no pollution generates in the production process and products have no toxicity and are green and environment-friendly.

Description

Technical field

[0001] The invention relates to an anti-rust pigment. Background technique

[0002] Iron trioxide, also known as iron red, has stable properties and does not change color at high temperature. As a coating, it has good weather resistance and has a certain anti-rust effect. It belongs to physical shielding and anti-rust, and is generally used for lower-grade pigments; and phosphate It is a kind of anti-rust pigment, chemical anti-rust, non-toxic, pollution-free, and environmental protection. At present, zinc phosphate is mainly used. The price of zinc phosphate anti-rust pigment is high; the other is used for metal anti-rust in harsh environment. the effect is not very good. Summary of the invention

[0003] The purpose of the present invention is to provide an iron red composite antirust pigment.

[0004] The purpose of the present invention is achieved by the following way: a composite iron red anti-rust pigment, the anti-rust pigment contains the following weight ...
