Problems solved by technology

[0002] Ferric oxide, also known as iron red, has the characteristics of stable properties and no discoloration 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; while phosphate It is an anti-rust pigment, which belongs to chemical anti-rust, and has the characteristics of non-toxic, pollution-free, and environmental protection. At present, zinc phosphate is mainly used. Zinc phosphate anti-rust pigments are high in price; the effect is not very good

Embodiment 1

[0019] The iron trioxide and the iron phosphate are respectively dried to a moisture content of less than 1%, 60% of the iron trioxide and 40% of the iron phosphate are thoroughly mixed, and then crushed to a size greater than 325 mesh. If industrial waste residue is used, the content of iron trioxide and iron phosphate is above 60%.

Embodiment 2

[0021] In order to improve the coloring rate, vividness and hiding rate of the pigment, 1-20% of colorant is added to the pigment.

Embodiment 3

[0023] In order to improve the wettability and dispersibility of the pigment, 1-5% silane coupling agent is added to the 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 ...
