Problems solved by technology

For zinc phosphate antirust paint, zinc phosphate is highly water-soluble and should not be used alone. It is often used in conjunction with red lead, zinc yellow, zinc oxide, etc., which has little effect on reducing the environmental hazards of lead-based antirust paint. Therefore, from the perspective of technology There is no fundamental breakthrough in

Abstract

The nanometer composite antirust paint consists of alcoholic acid, epoxy ester, stuffing and assistant as well as nanometer composite antirust powder. The nanometer composite antirust powder is corrosion inhibitor mixture comprising nanometer titania powder and Fe3O4 or P2O3. The nanometer composite antirust paint has antirust performance superior to traditional antirust paint with red lead, iron red, etc, salt water tolerance over 240 hr, no environmental pollution and harm to construction worker, simple production process and low cost, and may be sued widely in anticorrosive coating of various kinds of military facilities and civil facilities.

Description

technical field [0001] The invention relates to an antirust paint, in particular to an efficient, low-cost and environment-friendly antirust paint. Background technique [0002] Paint is a new type of polymer material and supporting engineering material that is coated on the surface of the protected and decorated substrate and can form a continuous film that is firmly attached. It has a wide range of applications. According to relevant reports, the annual economic loss caused by metal corrosion in the world is about 700 billion US dollars, accounting for 2-4% of the gross national product of various countries, and the annual metal corrosion loss in China also accounts for about 4% of the gross national product. The whole world has to pay a heavy price of 10% metal being corroded every year. Metal anti-corrosion is a major issue in the industry. [0003] Compared with other various anti-corrosion methods, anti-rust coatings are the most economical, most convenient and effect...
