Problems solved by technology

According to the survey, at present, in the research of anti-rust pigments at home and abroad, it is mainly modified on the basis of phosphate. The direction of modification is to form polymetallic polyphosphate double salt, modified polyphosphate (three) metal salts The antirust performance of red lead can be slightly higher than that of red lead, but its price is expensive, such as the zinc calcium phosphomolybdate we bought in the test, the price is as high as 300 yuan / kg

Abstract

The invention discloses a composite ferrum-titanium powder, a rust-preventive pigment for improving the tarnish proofness for anti-corrosive paint, characterized in that, the composite ferrum-titanium powder uses natural or artificially synthesized ferriferrous oxide having a fineness of 200-1200 sieve number as carrying agent, to be added by nano silicon oxide, titanium oxide, vanadium oxide, yttrium oxide, zinc oxide, ferric oxide and calcium carbonate.

Description

technical field [0001] The invention relates to an antirust pigment, in particular to a composite iron-titanium powder used for improving the antirust performance of an antirust paint. Background technique [0002] Coating is the most economical and convenient anti-corrosion material. Due to its excellent antirust performance, Hongdan antirust paint has been king in the field of antirust paint for nearly a hundred years. According to the introduction of the National Coatings Industry Information Center, my country's current annual consumption of anti-corrosion paint is more than 350,000 tons, not including the export of anti-corrosion paint, and the growth rate in 2001 reached 13%. In 1990, the national consumption of red lead reached 80,000 tons. In the past two years, the consumption of red lead has been declining, and the development trend is to gradually reduce and prohibit its use. Due to its excellent anti-rust performance and the lack of sound industrial hygiene and ...
