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 [0001] The invention relates to the technical field of chemical antirust raw materials, in particular to a composite phosphate antirust pigment. Background technique [0002] The loss caused by metal corrosion is becoming more and more serious with the development of industry. Although there are many anti-corrosion measures at present, the most widely used method is still the coating protection method. In this method, the antirust pigment is an important factor affecting the protection effect. For a long time, anti-rust pigments have always been dominated by compounds containing lead and chromium. Although their anti-rust effect is good, due to the increasing attention of human beings to the environment and health, such toxic anti-rust pigments have been gradually abandoned. use. Countries and regions such as the United States, Japan, and the European Community have formulated laws and regulations restricting the use of chemicals containing harmful heavy m...
