Problems solved by technology

[0003] At present, there are SiliconIZ type heat-resistant coatings produced in Japan in the international market, as well as Leaf brand heat-resistant coatings produced in the UK, but their operating temperature is <400 °C and they are very expensive.
The TH-1 and Type 2 heat-resistant coatings developed with the support of the former Ministry of Metallurgy of our country also have a service temperature below 400°C. The metal high-temperature protective coatings developed by Nanjing University of Aeronautics and Astronautics also fell off after being tried in the silicon steel branch of Wuhan Iron and Steel. So far, there is no such coating in the domestic market. Mature metal protective coatings above 400°C, metal protective coatings resistant to 1000°C are blank

Abstract

The heat resistant and wear resistant power-saving metal paint is produced through adding successively to stirrer nanoemter glue powder, calgon solution, modifying silica sol, acrylic acid, water soluble silicon oil, modified water glass, compounded stuffing, organic bentonite solution, butyrin, acetylacetone, N,N-methyl methane amide and coupling agent silane solution to obtain nanoemter powder modified micron level paint powder; and then dispersing the paint powder in powerful high speed dispersing machine. The paint has high temperature resistant, wear resistant and other advantages.

Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature-resistant, wear-resistant and energy-saving coating for metal. Background technique [0002] On October 26-28, 1999, the first China International Conference on Corrosion Control was held in Beijing. The meeting pointed out that in 1998, the economic loss caused by metal corrosion in my country was 280 billion yuan, and the economic loss caused by metal corrosion in industrially developed countries accounted for 2% of the GDP -4%, my country accounts for 6%, and 20-40% of the world's annual metal output, which is equivalent to more than 100 million tons of metal being corroded and lost, which has become an international serious problem. Anti-corrosion scientific and technological methods of modern science and technology are generally only used in normal temperature fields, such as paint, electroplating, cathodic protection, passivation film, non-metallic lining, etc. There are not m...
