Abstract
The invention discloses a composite phosphate anti-rust pigment. The anti-rust pigment contains 20-40 parts by weight of phosphate, 40-60 parts by weight of zinc salt and 10-30 parts by weight of alloy powder. The anti-rust pigment disclosed by the invention is subjected to active modification treatment, and the treated pigment has excellent hydrophobic and lipophilic functions and has good affinity to macromolecular substances in oil paint; and the prepared paint film is compact and is capable of shielding oxygen and water in air and preventing steel rusting.
Description
Technical field
The present invention relates to the antirust raw material technical field of chemical industry, specifically belong to a kind of composite phosphate rust-stabilising pigment.
Background technology
The loss that metallic corrosion causes is along with industrial expansion is on the rise.Although anticorrosive measure is a lot of at present, the most widely used coating protection method that remains.In this method, rust-stabilising pigment is the important factor of impact protection effect.For a long time, rust-stabilising pigment always is take the compound of leaded, chromium class as main, although its favorable rust preventing effect, because the mankind are to environment and healthy pay attention to day by day, the poisonous rust-stabilising pigment of this class is slowly abandoned.As worked out the legal provisions that the chemical that contains the harmful heavy metals such as lead, chromium is used in restriction in the countries and regions such as the U.S., Japan, the European Community.World Ship industry, metal anticorrosion engineering are also progressively being forbidden the coating that contains poisonous, harmful pigment such as red lead, zinc-chrome yellow.External each Port does not allow steamer leaded in coating, chromium to enter a port yet.
Summary of the invention
The object of this invention is to provide a kind of composite phosphate rust-stabilising pigment, through active modification, process, pigment after processing has fabulous hydrophobic oleophylic function, and he can have good avidity with polymer substance in paint, makes oxygen and the corrosion of moisture content prevention iron and steel in paint film densification, shroud air.
The technical solution used in the present invention is as follows:
A composite phosphate rust-stabilising pigment, it is phosphoric acid salt 20-40 part, zinc salt 40-60 part, alloy powder 10-30 part that this described rust-stabilising pigment contains parts by weight.
Described phosphoric acid salt comprise zinc phosphate, calcium phosphate, tertiary iron phosphate and aluminium triphosphate one or more.
Described zinc salt be zinc sulfate, zinc chloride one or more.
Compared with the prior art, beneficial effect of the present invention is as follows:
The activated treating product of the present invention has good wet dispersiveness, makes rust-inhibiting paint and is difficult for layering; Suitability is wide: this product is applicable to solvent based coating, and making priming paint, finish paint all can; Easy to use: by this product, to make paint, spray, all can brush convenient construction.
Embodiment
A composite phosphate rust-stabilising pigment, it is 30 parts of phosphoric acid salt, 50 parts of zinc salts, 20 parts of alloy powders that this described rust-stabilising pigment contains parts by weight, described phosphoric acid salt comprise zinc phosphate, calcium phosphate, tertiary iron phosphate and aluminium triphosphate one or more; Zinc salt be zinc sulfate, zinc chloride one or more.
