Abstract

The invention discloses an inorganic nanocementing agent, which is characterized by corrosion prevention, fire- proof, wearing resistant, acid-resistant and alkali reisistant. It takes silicasol and potassium metasilicate as raw material, and produced by adding a little amount of organic raw material or inorganic raw material, and the comprised raw material and their proportion by weight are as follows: nanocolloidal silica 10 -15, potassium metasilicate 20- 30, polyvinyl alcohol 1- 5, nano titanium dioxide 3- 6, titanium dioxide titanium dioxide 7- 12, calcining porcelain clay 2- 6, porcelain clay 2- 6, silicon zirconite powder 10- 14, barium sulfate powder and water 8- 15; or as that: nanocolloidal silica 10 -15, potassium metasilicate 20- 30, polyvinyl alcohol 1- 5, mica titanium 20- 30, nano zinc oxide 7- 12, high-alumina powder 2- 6, charring silicon 10- 18, barite powder 8- 16, and clean water 8- 15. The product will not deform at 1200 Deg. C, it can form permeating high- rigidity compact coating on metal surface, and there is no permission, cracking and separation when the gelatin is heated to 300- 500 Deg. C for several hours and for more than fives times of shock cooling and heating.

Description

Technical field: [0001] The utility model relates to a chemical product, in particular to an inorganic corrosion-resistant, fire-resistant and wear-resistant nanometer cementing material used for surface treatment in anti-corrosion engineering. Background technique: [0002] At present, the floors, acid drainage ditch, tanks, tanks, and other equipment in petroleum, chemical, metallurgical and other industrial sectors need to be treated with anti-corrosion spraying. In addition to the improved acid and alkali resistance of the sprayed coating, the fire resistance and wear resistance of the sprayed coating are also required. The performance is also getting higher and higher. Most of the coatings currently used are organic spray coatings. This coating has better acid and alkali resistance, but poor high temperature resistance, and is highly toxic and easy to age, especially in a sudden cold or hot environment. The coating is prone to cracking. Invention content: [0003] In...
