Abstract

The invention discloses a novel environment-friendly efficient anticorrosive paint which takes ironmaking steel slag as raw material. Steel slag micro powder with a little armco magnetic iron is obtained by grinding, magnetic separating, drying, milling, classifying and secondly magnetic separating the steel slag, power surface is treated by powder surface conditioning agent, and the product is obtained after additive is added into the steel slag micro powder. The preparation method of the paint comprises the steps: grinding the ironmaking steel slag; magnetic separating, drying, milling, classifying and secondly magnetic separating the grinded steel slag; surface chemical modifying powder granules; adding the additive and the like. The invention transforms the ironmaking steel slag with no or less value into the anticorrosive paint which has high value, good anti-corrosive property, no heavy metal and low cost, thereby not only solving the serious pollution problem of anticorrosive paint such as red lead type lead chromium, and the like, but also having good anti-corrosive property and cost performance in the anticorrosive paints.

Description

technical field [0001] The invention relates to an anti-rust pigment, in particular to a novel high-efficiency, environment-friendly and anti-rust pigment added to coatings. The invention also relates to a manufacturing method of the novel, high-efficiency, environment-friendly and anti-rust pigment. Background technique [0002] According to relevant reports, the economic loss caused by corrosion in the world exceeds 700 billion US dollars every year, accounting for 2-4% of the gross national product of various countries, and the annual corrosion loss in China also accounts for about 4% of the gross national product. There is a heavy price to pay for 10% of the metal being corroded away. [0003] Compared with other various anti-corrosion methods, coating with paint is the most economical, most convenient and effective, and the most widely used anti-corrosion method. etc.) corrosion primers are called anti-rust paints (or anti-corrosion primers, anti-corrosion paints), and...
