Rust-bearing anti-rust paint

Abstract

The invention relates to a rust-bearing anti-rust paint which is mainly prepared from rust-bearing anti-rust paint emulsion, calcium ferrite, zinc phosphate, zinc oxide, barium chromate, aluminum tripolyphosphate, mica ferric oxide, talcum powder, kaolin, wollastonite powder, water, curing agent and the like. The rust-bearing anti-rust paint has uvioresistant capacity, and can postpone aging of the paint film. The paint film has the characteristics of favorable corrosion resistance, high durability, acid / alkali / salt / water corrosion resistance, high adhesive force, high impact resistance, excellent bending resistance, long corrosion resistance time and the like.

Description

technical field [0001] The invention relates to a rust-resistant antirust paint and a preparation method thereof, belonging to the field of metal surface protection. Background technique [0002] The derusting effect of the metal surface directly affects the adhesion and durability of the paint film. At present, the main means of derusting are manual derusting, pickling derusting, sandblasting and shot peening, etc., but these derusting methods There are certain defects: manual derusting is mainly used for secondary derusting of ships, pipelines, bridges, etc. This method is labor-intensive, narrow in construction field, low in efficiency, high in cost, unsatisfactory in derusting effect, and seriously affects human health ;Pickling derusting is easy to produce "over-corrosion" and "over-hydrogen", and it is easy to produce secondary rust, and the discharge of pickling waste liquid is easy to cause environmental pollution; sandblasting and shot peening derusting equipment re...

[0002] The derusting effect of the metal surface directly affects the adhesion and durability of the paint film. At present, the main means of derusting are manual derusting, pickling derusting, sandblasting and shot peening, etc., but these derusting methods There are certain defects: manual derusting is mainly used for secondary derusting of ships, pipelines, bridges, etc. This method is labor-intensive, narrow in construction field, low in efficiency, high in cost, unsatisfactory in derusting effect, and seriously affects human health ;Pickling derusting is easy to produce "over-corrosion" and "over-hydrogen", and it is easy to produce secondary rust, and the discharge of pickling waste liquid is easy to cause environmental pollution; sandblasting and shot peening derusting equipment require large investment and high cost , it is difficult to function

[0003] In order to overcome the deficiencies in the above-mentioned various derusting methods, a kind of antirust paint with rust provided by the present invention overcomes the defects in derusting construction.
